XHHW-2 Cable

XHHW-2 Cable Description:

XHHW-2 cable is a thermoset product. Rather than PVC or other plastics, XHHW-2 cable is XLPE (crosslinked polyethylene) insulation. XLPE is more resistant to chemicals, ozone, and abrasions. Because of the chemistries involved, modern XLPE is far less toxic than PVC in the event of fire. In most applications, thermosets are more flexible than thermoplastics and are more advantageous for projects where complex, close-spaced bends are required. Thermoset compounds utilize a curing process which causes a chemical reaction, allowing the polymers to cross-link. Once cured, the thermoset insulation retain their shape and will not remelt when heat is applied. 



XHHW-2 Cable Construction:

Conductors: Bare copper or aluminum alloy 
Insulation: Abrasion, heat, moisture, and flame resistant cross-linkedpolyethylene (XLPE) insulation in various color

The Different Between XHHW-2 Cable And THHN Cable 

THHN/THWN-2 is a thermoplastic product. It uses a thinner PVC insulation, which can lead to current leakage and dielectric breakdown in demanding circuits or from chemical or environmental exposure. The PVC insulation in THHN/THWN-2 emits a toxic smoke when burned and is less flexible at cold temperatures. However, it is lighter in weight and less expensive to manufacture. 

THHN/THWN-2 CABLE:	XHHW-2 CABLE:
T = Thermoplastic	X = Cross-Linked Polyethylene (XLPE)
HH = High Heat Resistant	HH = High Heat Resistant
W = Water Resistant	W = Water Resistant
N = Nylon Jacket	(Not Required)
-2 = Temperature Rated 90°C Wet/Dry	-2 = Temperature Rated 90°C Wet/Dry

XHHW-2 Cable Application: 

XHHW-2 cables are primarily used for power distribution in conduit or other recognized raceways for services, feeders, and branch circuit wiring as specified in the National Electrical Code. The cable is suitable for use in wet or dry locations at temperatures not exceeding 90°C and is dual-rated for 600V or 1000V. 1/0AWG and larger are approved for cable tray use.
