TW/THW wires are intended for use as grounding wire and other general purpose power wiring in residential, commercial, and industrial applications.
Conductors are solid or stranded annealed or hard uncoated copper.
Insulation is a polyvinylchloride (PVC) material applied tightly to the conductor.
Surface or indent markings for cable identification
Conforms to ASTM B-3 and UL 83 for copper conductors
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.
1.Conductor
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.
2.Insulation
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.
3.Assembly
Single conductor cables can be paralleled or multiplexed for more efficient installations. Single conductor cables can also be pre-installed in conduit.
Applicable Standards:
Listed by UL as Type THW per Standard 83.
All sizes carry the VW-1 flame test designation.
Listed by UL as Oil Resistant I.
Listed by UL as Sunlight Resistant (250 kcmil and larger, black only)
250 kcmil and larger pass UL and IEEE-383 ribbon burner flame test and are listed For CT Use.
6. Conforms to Federal Specification J-C-30B
