Detailed Description of U1000 Series and 54mm², 56mm² Low-Voltage Power Cables

I. Product-Related Information

(1) Specification Parameters

The low-voltage Power Cables of models U1000 R2V, U1000 R02V and specifications 54mm², 56mm² have clear and detailed divisions in terms of specification parameters, which together determine the performance and application scope of the cables.

In terms of rated voltage, "U1000" clearly indicates that the rated voltage of these two cables is 1000V, and this voltage level enables them to perfectly adapt to low-voltage power distribution systems. In household electricity use, the common voltage is 220V, and the electricity voltage in commercial buildings and small industrial facilities is mostly below 380V. The rated voltage of 1000V provides sufficient voltage margin for these scenarios, ensuring that the normal use will not be affected by voltage fluctuations during power transmission, and also providing an important guarantee for the safe operation of the cables.

In terms of conductor structure, the specifications of 54mm² and 56mm² have clear meanings. "5" means that the cable contains 5 conductors. This multi-conductor design can meet different circuit requirements. For example, in a three-phase four-wire circuit, they can be used for phase lines, neutral lines, etc. "4mm²" and "6mm²" are the cross-sectional areas of each conductor, and this parameter is closely related to the current-carrying capacity of the cable. Generally speaking, the larger the cross-sectional area, the smaller the resistance of the conductor, and the less heat generated when transmitting current, so it can carry a larger current. Tests show that when the ambient temperature is 25℃, the long-term allowable current-carrying capacity of the 54mm² cable is about 30A; while the long-term allowable current-carrying capacity of the 56mm² cable can reach 40A at the same ambient temperature. This makes the 54mm² cable suitable for medium-power power transmission, such as connecting small motors with a power of about 7kW, 3-horsepower air conditioners and other equipment; the 56mm² cable can be used for higher-power scenarios, such as power supply for equipment with a power of more than 10kW, such as large water pumps and industrial ovens.

In addition, the thickness of the cable's insulation and sheath is also an important specification parameter. U1000 R2V and U1000 R02V Cables use polyvinyl chloride (PVC) as insulation and sheath materials, among which the insulation thickness is usually not less than 0.8mm, and the sheath thickness is not less than 1.2mm. This thickness design can effectively ensure the insulation performance and mechanical strength of the cable, and prevent safety accidents caused by insulation breakdown and sheath damage.

The outer diameter of the cable is also a parameter to be considered. The outer diameter of the 54mm² cable is about 15mm, and that of the 56mm² cable is about 18mm. Different outer diameter sizes will affect the laying method and installation space of the cable. In practical applications, it is necessary to select the appropriate specification of the cable according to the specific laying environment and installation requirements.

(2) Characteristic Uses

For example, in the power supply of temperature control equipment and irrigation water pumps in greenhouses, 54mm² and 56mm² cables can provide appropriate power transmission according to the power demand of the equipment, ensuring the smooth progress of agricultural production.

(3) Material and Style

The materials of U1000 R2V and U1000 R02V cables are carefully considered to ensure the stability and reliability of their performance.

In terms of Conductor Material, high-purity electrolytic copper is used as the conductor material. Electrolytic copper has excellent electrical conductivity, with high conductivity, which can reduce energy loss during current transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and mechanical strength, which is easy to be processed into conductors of various specifications, and can bear certain mechanical stress during use, not easy to break.

Polyvinyl chloride (PVC) is selected as the insulation and sheath material. PVC is a commonly used polymer material with many advantages. Firstly, it has good insulation performance, which can effectively prevent current leakage and ensure the safe operation of the cable. Secondly, PVC has good wear resistance, which can resist external friction and collision during cable laying, installation and use, reducing the risk of sheath damage. Moreover, PVC has certain chemical corrosion resistance, which can resist the erosion of acids, alkalis, oils and other chemicals, and is suitable for various complex environments. In addition, PVC material has strong flexibility, making the cable easy to bend and lay, and able to adapt to different installation scenarios.

In terms of style, these cables are all of circular structure, which is conducive to cable production, laying and installation. Circular cables have less resistance during laying, and can be more conveniently piped, buried or laid openly. At the same time, the circular structure makes the stress of the cable more uniform, and can better bear external pressure and tension during use.

The color of the cable is also part of its style. Usually, the insulation layer is distinguished by different colors to facilitate the identification of different conductors during installation and maintenance. For example, phase lines can be in yellow, green and red, neutral lines in blue, and ground lines in yellow-green 双色. Such color identification conforms to industry standards, can effectively avoid wiring errors, and improve construction efficiency and safety.

(4) Production Process

The production process of low-voltage power cables of models U1000 R2V, U1000 R02V and specifications 54mm², 56mm² strictly follows relevant industry standards and adopts advanced production technology to ensure product quality.

The first is the manufacturing process of the conductor. High-purity electrolytic copper rods are selected as raw materials, and the copper rods are drawn into Copper Wires of required diameter by a wire drawing machine. During the wire drawing process, it is necessary to control the drawing speed and tension to ensure the dimensional accuracy and mechanical properties of the copper wires. Then, multiple copper wires are stranded together to form a conductor. The stranding process can improve the flexibility and filling factor of the conductor, reduce the skin effect of the conductor, and improve the conductivity.

Next is the insulation extrusion process. The Stranded Conductor is fed into the extruder, and a layer of polyvinyl chloride insulation is extruded outside the conductor. During the extrusion process, it is necessary to accurately control the extrusion temperature, speed and pressure to ensure that the insulation layer has uniform thickness, smooth surface and is closely combined with the conductor. The thickness and quality of the insulation layer directly affect the insulation performance of the cable, so this link needs strict monitoring.

Then is the cabling process. Multiple Insulated Wire cores are stranded together according to a certain stranding direction and pitch to form the cable core. During the cabling process, it is necessary to add fillers in the middle of the cable core to ensure the roundness and stability of the cable core. The filler usually adopts materials such as polypropylene rope, which has certain strength and flexibility.

After that is the sheath extrusion process. A layer of polyvinyl chloride sheath is extruded outside the cabled core. The sheath extrusion process is similar to the insulation extrusion process, and various parameters need to be controlled to ensure that the sheath has uniform thickness, smooth surface and is closely combined with the cable core. The main function of the sheath is to protect the cable core from the external environment, so its quality is crucial.

During the production process, multiple quality inspections are also required. For example, the DC resistance test of the conductor to ensure that the conductivity of the conductor meets the requirements; the insulation resistance test to check the insulation performance of the insulation layer; the withstand voltage test to assess the insulation strength of the cable under a certain voltage; and the tests of the sheath's thickness, outer diameter, mechanical properties, etc. Only products that meet the standards in all indicators can leave the factory.

In addition, attention is paid to environmental protection and safety during the production process. Environmentally friendly polyvinyl chloride materials are used to reduce environmental pollution during production. At the same time, the production workshop is equipped with complete safety facilities to ensure the safety and reliability of the production process.

II. General Product Information

(1) Packaging

In order to ensure the quality of the cable during transportation and storage, the low-voltage power cables of models U1000 R2V, U1000 R02V and specifications 54mm², 56mm² adopt scientific and reasonable packaging methods.

Cables are usually packaged in wooden reels or cable drums. The material of the wooden reel or cable drum is high-quality wood, which has sufficient strength and rigidity to bear the weight of the cable and the external force during transportation. The cable is neatly wound on the wooden reel or cable drum, and the winding tension needs to be controlled during the winding process to avoid damage to the cable due to excessive stretching or extrusion.

The outer layer of the cable will be wrapped with a layer of plastic film or linen to prevent the cable from being exposed to dust, moisture and direct sunlight during transportation and storage. The plastic film has good moisture-proof performance, and the linen has certain air permeability. The appropriate wrapping material can be selected according to different storage environments.

Each packaging unit is attached with a detailed label, which indicates the product model, specification, length, rated voltage, production date, manufacturer and other information, facilitating users' identification and acceptance. At the same time, the label will also mark some precautions, such as "Do not invert" and "Handle with care", to remind transportation and storage personnel to handle the cable correctly.

For small batches of cables, coil packaging can also be adopted. The cable is wound into a coil of a certain diameter, firmly bound with plastic tape, and then put into a carton or woven bag. This packaging method is convenient for handling and storage, and is suitable for the transportation and sales of a small number of cables.

(2) Transportation

The transportation process of cables needs to be carried out in strict accordance with relevant regulations to ensure the safety of products.

Before transportation, the packaged cables need to be inspected to ensure that the packaging is intact and the labels are clearly visible. For cables packaged in large wooden reels or cable drums, forklifts or cranes are needed for loading and unloading. During loading and unloading, collision and extrusion should be avoided to prevent damage to the cable drum or rupture of the cable sheath.

During transportation, the cable should be placed horizontally or vertically, avoiding inversion or excessive inclination. For long-distance transportation, the cable needs to be fixed on the transport vehicle with ropes to prevent displacement or falling due to 颠簸 during driving. At the same time, the cable should be avoided from contact with other sharp objects or corrosive substances to prevent damage to the cable.

Attention should also be paid to the impact of ambient temperature during transportation. Polyvinyl chloride materials will become brittle in low-temperature environments and are easy to crack; in high-temperature environments, they will become soft, which may lead to cable deformation. Therefore, during transportation, the cable should be 尽量避免 exposed to extreme temperature environments, and shading or heat preservation measures should be taken when necessary.

In addition, transport vehicles should abide by traffic rules, maintain stable driving, and reduce sudden braking and sharp turns to reduce the impact and vibration of the cable during transportation.
