TW/THW is a solid or stranded, soft annealed copper conductor insulated with Polyvinylchloride (PVC). It is UL rated for 600 volts. #10, 12, and 14 AWG are 19 strands; all others are "highly flexible" stranding constructions.
Annealed uncoated copper conductor. Class B, soft drawn, bare copper per ASTM B3 and ASTM B8. Both tinned copper conductors and extra-flexible conductors are available as options.
Heat and moisture resistant polyvinyl chloride (PVC) meeting the requirements of ICEA S-95-658 (NEMA WC 90) UL 83 for Type THW and wires. The insulation is suitable for use in wet or dry locations at a conductor temperature not exceeding 75° C for normal operation.
Single conductor cables can be paralleled or multiplexed for more efficient installations. Single conductor cables can also be pre-installed in conduit.
TW/THW wires are intended for use as grounding wire and other general purpose power wiring in residential, commercial, and industrial applications.
