PVC Insulated PVC Sheathed cables 300 - 500 Volts without circuit protective conductor (Flat, Twin and Three Core)

CONSTRUCTION:

CONDUCTOR :

Soft drawn annealed copper conductor as per UL 83. Available in solid or stranded type for sizes 14, 12 and 10 AWG. Sizes 8 AWG and larger available in stranded only.

INSULATION :

Extruded polyvinyl Chloride (PVC) compound rated 75 °C and 90 °C.

JACKET :

Tough, smooth, heat and light stabilized, low moisture absorption nylon conforming to UL requirements for type THHN or THWN. This jacket offers a great degree of protection to the PVC insulation from abrasion and cut-through which may be encountered in pulling wire through conduits. Nylon has long been recognized as one of the toughest jacketing material used in wire and cable manufacturing.

FEATURES :

1. Meets UL 'VW-1 Flame Test requirements.
2. Wet or dry locations - Rated 90 °C dry 75 °C wet.
3. Resistant to gas and oil exposure : Rated gasoline and oil resistant II per UL.
4. Versatile : Can be used as follows
        a. THHN : 90 °C dry building wire
        b. THWN : 75 °C wet and 90°C dry building wire
        c. MTW : 90 °C machine tool wire
5. Pulls easier : tough smooth nylon jacket over PVC insulation.
6. Small diameter : more conductors per conduit.

APPLICATIONS :

Type THHN - THWN building wires are intended for general purpose applications and may be installed in conduit, duct or other recognized raceways in wet or dry locations.

Type THHN - THWN wires are designed to operate at conductor temperatures of 75°C and 90°C for 600 volts service in wet and dry locations respectively. Applicable for both new work and rewiring installed where the smaller wire diameter permits additional circuits or larger conductors, to be installed in the conduit without exceeding maximum fill limitations.

Type THHN - THWN wires are also recommended for industrial installation where exceptional resistance to heat and corrosive atmospheres are needed, such as chemical plants, oil refineries, paper mills, etc.
