Description:
THHN Wire is a general-purpose cable that is designed for hazardous environments and high heat applications. Its outstanding feature is its very high heat-resistant jacket and its thermoset tough insulation.

THHN cable is a general-purpose power cable for use in heavy duties applications involving high-heat emittance. Its 90°C temperature limit allows it to serve in high heat environments and applications fire risks. The fire-retardant jacket will prevent further effect of the fire on the cable. The nylon jacket does not react with oils, solvents and industrial chemicals that would otherwise destroy the cable and therefore qualifying it to be used in marshy and oily environments.

The weather resistant THHN Cable can be used in seas and tropical areas because its nylon jacket can resist sunlight.
THHN is an acronym for;
T-Thermoplastic
HH-high Heat resistant
N-Nylon Coating
