Large industrial equipment such as rolling mills, large compressors, and industrial boilers have huge power and high requirements for power transmission. The 240mm² cable can stably transmit power to these equipment, ensuring the continuous progress of production. The total power transmission of the production line also often uses this specification of cable to ensure the stable and reliable power supply of the entire production line. The 150mm² and 120mm² cables are suitable for small and medium-sized industrial equipment, such as CNC machine tools, injection molding machines, and fans. In the workshop power distribution system, they serve as branch cables to distribute power to various equipment, ensuring the orderly development of workshop production. The 70mm² cable can be used for small motors, conveyors, workshop lighting systems, etc., providing power support for these low-power equipment.

This series of cables is widely used in urban power distribution networks. For power transmission between substations and residential communities, appropriate specifications can be selected according to the power load of the community. For large residential communities, 150mm² or 240mm² cables can meet the electricity demand of a large number of residents; for small and medium-sized communities, 120mm² or 70mm² cables can be used. In the power transmission of urban road lighting systems, 70mm² cables are widely used due to their appropriate current-carrying capacity and easy laying characteristics, ensuring the stable operation of road lighting. In addition, in the power distribution network of commercial complexes, cables of different specifications have clear division of labor. 240mm² cables are used as main cables to transmit power, 120mm² and 150mm² cables are used for power distribution trunks of each floor, and 70mm² cables are used for branch power distribution of shops, offices, etc.

This series of cables is also indispensable in construction projects. In the power distribution system of high-rise buildings, 240mm² cables can be used as low-voltage main lines to transmit power from the distribution room to the distribution rooms of each floor; 150mm² and 120mm² cables are used for power distribution trunks in the floor to distribute power to different areas; 70mm² cables are used for branch lines such as lighting and sockets in the room. In large public buildings such as gymnasiums and convention centers, 240mm² cables can meet the power demand of a large number of equipment such as air conditioners, lighting, and audio in the venue. 120mm² and 150mm² cables are used for power distribution in various functional areas to ensure the normal operation of various facilities in the building.

The single core XLPE PVC insulated copper power cable has been carefully considered in material selection and has a reasonable style design to ensure the performance and applicability of the product.

The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can effectively reduce energy loss during power transmission and improve transmission efficiency. At the same time, electrolytic copper has good ductility and Flexibility. During the production of the cable, it can be drawn into fine Copper Wires and stranded, which is convenient for processing into conductors of different specifications. During laying and use, the conductor can withstand a certain degree of bending and stretching, and is not easy to break, ensuring the service life of the cable.

The insulation layer is made of XLPE (cross-linked polyethylene) material, which is a polyethylene treated by cross-linking. Compared with ordinary polyethylene, XLPE has significantly improved heat resistance, and can operate stably for a long time at a working temperature of 90℃, with a short-term overload temperature of up to 130℃, which can adapt to the possible temperature rise during power transmission. XLPE has high insulation resistance, good corona resistance, and low dielectric loss, which can effectively prevent leakage and arcing, improving the safety performance of the cable. In addition, XLPE also has good chemical stability and aging resistance, which can resist the erosion of various chemical substances and prolong the service life of the cable.

The outer sheath is made of PVC (polyvinyl chloride) material. PVC has excellent mechanical properties, with high tensile strength and elongation at break, which can withstand external mechanical forces such as extrusion and collision, protecting the internal insulation layer and conductor from damage. PVC material has good corrosion resistance, which can resist the erosion of acid and alkali substances, moisture in the soil, as well as oxygen and ozone in the air, and is suitable for use in various complex environments. At the same time, the PVC sheath also has certain flame retardant performance, which can delay the spread of flames in case of fire and reduce fire losses.

In terms of style, the cable has a single core structure, which makes the cable more flexible and easier to lay, especially in narrow spaces and curved paths, the advantage of Single Core Cable is obvious. The appearance of the cable is round with a smooth surface. This design reduces the friction during laying, facilitating pipe threading and buried laying. The sheath color is usually black, which has good weather resistance, can absorb sunlight heat, reduce the impact of temperature changes on cable performance, and is also convenient for identification and maintenance in various environments.

The production process of single core XLPE PVC insulated copper power cable adopts advanced technology, and each link is strictly controlled to ensure that the product quality meets the standards.

In the conductor manufacturing link, first, high-purity electrolytic copper rods are drawn into copper wires of the required diameter through a wire drawing machine. During the wire drawing process, it is necessary to control the wire drawing speed, mold size, and cooling system to ensure the dimensional accuracy and surface quality of the copper wires. The drawn copper wires undergo annealing treatment, heated to a certain temperature under the protection of inert gas to eliminate internal stress of the copper wires and improve their flexibility and conductivity. Then, multiple copper wires are regularly stranded by a stranding machine to form a conductor. During the stranding process, it is necessary to ensure uniform stranding pitch to improve the filling coefficient and stability of the conductor.

The insulation extrusion process is one of the key links. Using a dry cross-linking production line, the Stranded Conductor is fed into the extruder, and a layer of XLPE insulation is extruded outside the conductor. Before extrusion, the XLPE material needs to undergo strict drying treatment to remove moisture and prevent bubbles in the insulation layer. During the extrusion process, the extrusion temperature, pressure, and speed are accurately controlled to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor. The extruded Insulated Wire core enters the cross-linking tube and undergoes cross-linking reaction in a high-temperature and high-pressure nitrogen environment, so that the XLPE molecules form a three-dimensional network structure, thereby improving the performance of the insulation layer. After cross-linking, the insulated wire core undergoes cooling, traction, and other treatments to obtain qualified insulated wire cores.

In the sheath extrusion process, the insulated wire core is fed into the sheath extruder, and a PVC sheath is extruded outside the insulation layer. Before extrusion, the PVC material needs to be mixed and granulated to ensure the uniformity and performance stability of the material. During the extrusion process, the extrusion parameters are controlled to ensure that the sheath has uniform thickness, flat surface, and is closely attached to the insulation layer. The extruded cable undergoes cooling, drying, printing, and other treatments. The printed content includes cable model, specification, rated voltage, manufacturer, etc., which is convenient for identification and traceability.

During the production process, quality inspection runs through. The DC resistance test of the conductor ensures that its conductivity meets the standards; the tests of the insulation layer's thickness, eccentricity, and withstand voltage ensure the insulation performance; the tests of the sheath's thickness, appearance, and mechanical properties ensure the sheath quality. In addition, the finished cable also needs to undergo partial discharge test, thermal aging test, etc., to comprehensively inspect the performance of the cable. Only products that pass all tests can leave the factory for sale.

Attention is also paid to environmental protection and safety during the production process. Environmentally friendly raw materials and additives are used to reduce the emission of harmful substances during production. The production workshop is equipped with complete waste gas and wastewater treatment systems to ensure that emissions meet the standards. At the same time, the production equipment adopts advanced automatic control systems to reduce human operation errors and improve production safety.

The packaging of single core XLPE PVC insulated copper power cable is scientific and reasonable, which can effectively protect the quality of the product during transportation and storage.

For long-length cables, cable reels are used for packaging. There are two types of cable reels: wooden and steel. The appropriate material is selected according to the weight and specification of the cable. Wooden cable reels are made of high-quality hardwood, which has sufficient strength and rigidity to bear the weight of the cable and external forces during transportation. Steel cable reels are welded with high-strength steel, which has stronger bearing capacity and is suitable for large-size and heavy-weight cables. The cable is neatly wound on the cable reel, and the tension is controlled during the winding process to avoid excessive stretching or extrusion of the cable. The outer layer of the cable is wrapped with a layer of plastic film, which plays a role in moisture-proof and dust-proof, preventing the cable from being polluted and eroded by moisture during storage and transportation. Baffles are installed on both sides of the cable reel, and the height of the baffle is higher than the winding height of the cable to prevent the cable from slipping off the cable reel.

For short-length cables, coil packaging is adopted. The cable is wound into a coil with a diameter of 500-800mm, firmly bound with plastic straps or steel wires, and then put into a strong carton or woven bag. The material of the carton and woven bag has certain strength, which can protect the cable from external extrusion and collision. The packaging clearly prints the product's model, specification, length, production batch number, implementation standard, manufacturer, and other information, which is convenient for users to identify and accept. At the same time, warning signs such as "Do not invert", "Handle with care", "Moisture-proof and sun-proof" are also marked on the packaging to remind transportation and storage personnel to handle correctly.

For exported products, the packaging must meet international standards and the requirements of the importing country. Wooden packaging is fumigated and accompanied by a fumigation certificate to prevent the spread of pests and diseases. The labels on the packaging are in both Chinese and English, which is convenient for international customers to identify. In addition, according to customer requirements, pallet packaging and other methods can also be adopted to improve transportation efficiency.

The transportation process of single core XLPE PVC insulated copper power cable strictly follows relevant regulations to ensure that the products are safely delivered to the destination.

Before transportation, a comprehensive inspection of the packaged cables is carried out to confirm that the cable reels are firm, the cables are neatly wound, the packaging is intact, and the labels are clear. For large cable reels, forklifts or cranes are used for loading and unloading. During loading and unloading, collision and extrusion are avoided to prevent deformation of the cable reels and damage to the cable sheath. During loading and unloading, operators must abide by the operating procedures to ensure personal and equipment safety.

During transportation, the cable reels should be placed horizontally or vertically, avoiding inversion. For long-distance transportation, the cable reels are fixed on the transport vehicle with steel wire ropes or fastening belts to prevent displacement or falling due to bumps, sudden braking, etc., during driving. The transport vehicle should choose a route with good road conditions, avoiding driving on rough roads to reduce vibration and impact on the cable.

Attention should be paid to the impact of ambient temperature during transportation. In high-temperature summer, avoid the cable being exposed to sunlight for a long time. A sunshade cloth can be used to cover it to prevent the cable from overheating; in low-temperature winter, prevent the cable from freezing to avoid the sheath from becoming brittle and breaking due to low temperature. In case of rain and snow, take rainproof and moisture-proof measures to ensure that the packaging is intact and prevent rainwater from seeping into the cable.

During transportation, avoid contact between the cable and sharp objects and corrosive substances to prevent damage to the cable. The transport vehicle should be kept clean to avoid contamination of the cable by oil stains, etc. At the same time, traffic rules must be observed during transportation, and the transportation time should be reasonably arranged to ensure that the cable arrives on time.
