CONSTRUCTION PARAMETER

Overview

APPLICATION

General use in commercial and industrial construction, and installations where resistance against oils and gasoline is required. May be used for power and control circuits in recognized raceways, in wet or dry locations, and in presence of gases, gasoline and chemicals. Also suitable as machine tool and switchboard wiring.

STANDARD

UL 83

MAXIMUM OPERATING VOLTAGE:

600 volts

MAXIMUM CONDUCTOR TEMPERATURE

Dry locations (THHN): 90°C
Dry and wet locations (THWN): 75°C
In oil (Gasoline and Oil resistant II): 75°C

FEATURES

1)Good resistance to moisture, heat, oil, gasoline, chemicals and grease.
2)Suitable for installation where thermal overload exists.
3)Strict quality control during manufacturing process.
4)Flame retardant, UL listed as VW-1.
5)Smooth nylon jacket aids in easier pulling.
6)Superior abrasion and mechanical properties.
