Introduce to THHN cable
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor and compared to the PVC cable, THHN has been more and more common used and popular in many countries, such as The Philippines, Australia, Peru and other South American countries.
THHN cable has better electrical and physical properties than ordinary PVC insulated wire and cable: nylon sheathed wire and cable has better heat resistance, the characteristics of small weight loss under high temperature operation, can improve the instantaneous thermal overload resistance of wire, can slow down or reduce the escape or migration of PVC components. THHN cable has the characteristics of corrosion resistance, self-lubrication and oil resistance. Compared with PVC insulated wire and cable of the same section, THN cable has the characteristics of small outer diameter, light weight, small static friction coefficient and corrosion resistance, which can improve the safety and applicability of laying. THHN cable rated operating voltage 450/750V, widely used in household appliances, aerospace systems, construction and lighting. The long-term working temperature of the cable is 90℃ or 75℃, the laying temperature is not less than 0℃, and the bending radius should not be less than 4 times of the cable diameter.
As one of most commonly used cable to wiring most of residential structures, the THHN cable outermost sheath denotes the gauge of the wire inside:
