UL 83 Standard T90 Nylon Cable

T90 cable features a high temperature rating and heat resistance, conforms to common North American cable standards, and employs an improved insulation and sheath construction. The T90 designation is commonly used to indicate that the cable can operate continuously at 90°C (in a dry environment), a higher temperature rating compared to the older standard (TW75 only allows 75°C). In actual product labeling, T90 often appears together with designations such as THHN/THWN-2/MTW, indicating a composite-rated building wiring type.

T90 copper cable uses solid or stranded copper conductors, conforming to ASTM B3 / ASTM B787 standards. It uses thermoplastic polyvinyl chloride (PVC) as insulation, providing heat and moisture resistance. The cable is sheathed with nylon or special PVC, which not only protects the insulation but also reduces friction during pulling, facilitating threading through conduits.

T90 wire has passed rigorous UL certification (UL File No. E544861), Whether for retail or major engineering projects, our wires are more easily selected by engineering consultants, electrical contractors, and owners, meeting the UL certification requirements in tender documents and engineering specifications.

T90 cable is a copper-core building cable rated for 600V and with a maximum operating temperature of 90°C (dry environment), widely used in residential, commercial, and industrial electrical systems. It features PVC insulation with a nylon or low-friction outer sheath, making it suitable for installation in conduits, cable trays, or enclosed wiring systems. Its excellent heat resistance, mechanical strength, and ease of installation make T90 cable a common and reliable general-purpose building wiring solution in North America and Canada. 

Exporting to 80+ countries and regions, we bring proven global export experience and trusted wires & cables to customers worldwide.

Geritel Wire is a professional T90 copper wire manufacturer. We have long exported to North America, Latin America, and other regions, and are familiar with the local market standards and application requirements for wires. Our stable quality and professional export experience have made us a trusted partner for overseas customers.

T90 wire is typically offered in coil packaging, small wooden spools, large wooden spools, and carton packaging, depending on the wire diameter and ordered length. Coil packaging is mostly used for small gauge and short length cables; small wooden spools are suitable for medium diameter and standard engineering lengths; large wooden spools are used for long-meter or large-section T90 wires to prevent cable deformation; and carton packaging is suitable for cut-to-length products, facilitating batch use and inventory management.

Geritel Wire Manufacturer holds 50+ international certifications, including UL, cUL, SAA, TUV, CE, VDE, ISO, and others. Our cables meet the highest global quality and safety standards.
