90°C Thw90 8 AWG stranded copper wire (600V/1kv heat-resistant PVC) is a high-performance wire designed specifically for high-temperature environments. With its excellent heat resistance and stable electrical performance, it plays a key role in electrical systems under various high-temperature working conditions.​ In terms of specification parameters, the rated temperature of this wire is 90°C, enabling it to work stably for a long time in high-temperature environments, far exceeding the temperature resistance limit of ordinary wires. It is suitable for scenarios such as high-temperature industrial workshops, kitchen equipment, and around heating systems. The wire gauge is 8 AWG (American Wire Gauge), corresponding to a cross-sectional area of approximately 8.37mm². This specification gives it a strong current-carrying capacity. At the rated temperature of 90°C, the continuous current-carrying capacity can reach about 40A, which can be adapted to high-power electrical equipment, such as industrial ovens and large air conditioning units. The conductor is made of multiple strands of fine copper wires stranded together, which not only enhances the flexibility of the wire, making it easy to bend and lay in complex high-temperature equipment interiors or narrow spaces, but also improves its vibration resistance and fatigue resistance, prolonging the service life. At 20°C, the maximum resistance of the conductor does not exceed 2.06Ω/km, ensuring efficient current transmission and low energy loss. The insulation layer is made of heat-resistant PVC material with a thickness of about 1.2-1.5mm, which has excellent electrical insulation performance. The insulation resistance is greater than 100MΩ·km at room temperature, which can effectively isolate current and prevent leakage and short-circuit accidents. At the same time, the insulation layer can still maintain good mechanical properties and insulation effect at a high temperature of 90°C without softening or cracking. The rated voltage of the wire is 600V/1kv, which can meet the power supply needs of medium and low-voltage electrical systems and is suitable for circuits of different voltage levels. The outer diameter of the wire is about 6.5-7.0mm, which is suitable for conventional high-temperature wire tubes and installation spaces, making construction convenient.​ In terms of characteristic uses, the application scenarios of this wire are concentrated in high-temperature environments or fields with high requirements for heat resistance. In the industrial field, it can be used as the power connection line for high-temperature equipment such as industrial kilns, drying equipment, and heat treatment production lines.

The high temperature and moisture environment in the kitchen have high requirements for the heat resistance and moisture resistance of the wire, and this wire can adapt well; in heating systems, it can be used for electrical connection lines of wall-hung boilers and floor heating equipment. The temperature around the heating equipment is high when it is running, and this wire can ensure the safe operation of the line; in the automobile manufacturing industry, it can be used as part of the electrical lines in the automobile engine compartment. The temperature in the engine compartment is high and there is vibration, and the heat resistance and vibration resistance of this wire can meet the requirements; in power station auxiliary equipment, such as electrical lines around steam turbines and boilers, this wire can also be used to adapt to the high-temperature working environment of the power station.​ In terms of materials, the conductor is made of high-purity electrolytic copper with a purity of more than 99.9%, which has excellent conductivity, can transmit current efficiently and reduce energy loss. Copper has good thermal conductivity and can dissipate heat quickly in high-temperature environments, avoiding affecting the wire performance due to heat accumulation. At the same time, copper has excellent ductility and toughness, making the stranded conductor structure stable and not easy to break, and can withstand the thermal expansion and contraction stress in high-temperature environments. The insulation layer is made of heat-resistant PVC material, which is added with heat-resistant additives on the basis of ordinary PVC, enabling it to be used for a long time at a high temperature of 90°C without aging. This material also has good chemical corrosion resistance, can resist the erosion of oil stains, moisture, etc., and adapt to complex high-temperature environments. In addition, heat-resistant PVC has certain flame retardancy, burns slowly when exposed to open fire, and can self-extinguish after leaving the fire source, improving the safety of the wire.​ In terms of production process, the wire is made through multiple strict processes. First, copper wire drawing, drawing high-purity copper rods into fine copper wires of required diameter. During the drawing process, the temperature and tension are strictly controlled to ensure the stable performance of the copper wires; then stranding, stranding multiple strands of fine copper wires into conductors according to specific processes. During stranding, ensure that each strand of copper wire is evenly stressed and closely arranged to enhance the flexibility and stability of the conductor; next, insulation layer extrusion, wrapping heat-resistant PVC material around the outer layer of the conductor through an extruder. The extrusion temperature is controlled at a high level to ensure that the heat-resistant PVC material is fully plasticized, closely combined with the conductor, and the insulation layer thickness is uniform; then high-temperature curing treatment, placing the wire in an environment above 90°C for aging test to 检验 the performance stability of the insulation layer at high temperature; then spark test to detect the integrity of the insulation layer to ensure no pinholes, cracks and other defects; finally, taking up, cutting and packaging. Each process has strict quality control to ensure that the products meet the relevant standards and specifications of heat-resistant wires.​ In terms of general information, the packaging adopts reels or high-temperature resistant cartons according to different lengths, and the outer layer is wrapped with moisture-proof and fireproof plastic film to prevent moisture and dust during transportation and storage, and avoid the impact of high-temperature environment on the packaging. During transportation, severe collision, exposure to sunlight and contact with open fire should be avoided to prevent damage to the insulation layer and affect the heat resistance. A comprehensive high-temperature performance test and electrical performance inspection will be carried out before delivery to ensure that the products are qualified. The manufacturer provides sample services to facilitate users to test and adapt in high-temperature environments. In terms of after-sales service, a 1-3 year warranty period is provided.

This product is a THW-type building wire specially designed for the Philippine market, featuring lead-free environmental protection, dual protection against heat and moisture, thermoplastic insulation material, and a rated voltage of 600V. It serves as a core power transmission solution for indoor and outdoor wiring in residential, commercial buildings, and light industrial sites in the Philippines. Relying on its adaptability to the local climate and strict safety compliance, it is widely used in building main wiring, electrical equipment connection, and fixed power system construction, meeting the long-term stable electricity demand under the high-temperature and high-humidity climate in the Philippines.​ In terms of core characteristics, environmental protection, and safety, the "lead-free" design is one of the key advantages of this wire. From the insulation material to the conductor coating, the product contains no lead, fully complying with Philippine and international environmental standards. It avoids potential harm to soil, water sources, and human health caused by traditional lead-containing wires during production, installation, and disposal. Especially, it adapts to the increasingly strict regulatory requirements for the environmental protection of building materials in the Philippines, while ensuring the health and safety of construction workers and residents. In addition, the lead-free material does not sacrifice the performance of the wire; instead, through formula optimization, the insulation layer maintains flexibility while improving anti-aging ability, extending the product's service life.​ The dual protection characteristics of heat resistance and moisture resistance are customized for the Philippine climate. The Philippines has a tropical monsoon climate, with high temperatures throughout the year and high humidity during the rainy season. Ordinary wires are prone to softening and aging of the insulation layer due to high temperatures, or leakage risks caused by humid environments. The thermoplastic insulation layer of this THW wire has undergone special high-temperature resistant modification treatment, which can maintain stable insulation performance in relatively high-temperature environments (usually up to 75℃-90℃, depending on specific product specifications) without softening, adhesion, or insulation failure. At the same time, the insulation layer has excellent moisture resistance, which can effectively isolate moisture in the air. Even when used in high-humidity environments during the rainy season or areas close to water sources (such as kitchens and bathrooms), it can prevent the decline in electrical performance caused by the insulation layer absorbing moisture, greatly reducing safety hazards such as short circuits and electric leakage, and ensuring the reliable operation of the power system under extreme climates.​ In terms of electrical performance and application scenarios, the 600V rated voltage adapts to the power system needs of most buildings in the Philippines. It can meet the power transmission needs from residential lighting circuits, socket power supply to small and medium-sized power equipment (such as air conditioners, elevators, commercial freezers) in commercial buildings, covering mainstream power consumption scenarios from low voltage to medium voltage inside buildings. Its thermoplastic insulation material has both good electrical insulation and mechanical strength, with high insulation resistance, which can effectively isolate the conductor from the outside world and prevent current leakage. At the same time, the material has a certain degree of wear resistance and chemical corrosion resistance, which can cope with slight friction during building construction and contact with common indoor chemicals (such as cleaning agents), protecting the internal conductor from damage.​ In terms of compliance and regional adaptability, this THW wire strictly follows the Philippine National Electrical Code (such as the Philippine Electrical Code PEC) and international standards for THW-type wires. From the accuracy of the conductor cross-sectional area, the thickness of the insulation layer to the heat and moisture resistance performance, all have passed third-party testing and certification, ensuring that the product meets the acceptance requirements of local construction projects in the Philippines. In addition, the product optimizes the wiring flexibility according to the characteristics of Philippine building construction. The overall flexibility of the wire is moderate, which is convenient for threading and installation in conduits or wire troughs in different positions such as building walls, ceilings, and floors, adapting to various construction scenarios such as new house construction and old house circuit transformation. Whether in Luzon Island with high temperature and heavy rain, or in the Visayas Islands with high humidity, this wire can perform stably, providing safe, durable, and environmentally friendly power transmission guarantee for various buildings in the Philippines, and is a preferred product in the local building electrical field.
