A Brief Know to Cable THHN

Cable THHN means nylon sheathed wire and cable, one of the American cable and wire standard UL83 and belong to a kind of building cable. THHN cable has better electrical and physical properties than ordinary PVC insulated wire and cable: cable THHN 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. Cable THHN and wire has the characteristics of corrosion resistance, self-lubrication and oil resistance.  Compared with PVC insulated wire and cable of the same section, cable THHN and wire 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. Cable THHN and wire’s rated operating voltage is 450/750V, widely used in household appliances, aerospace systems, construction and lighting.  The long-term working temperature of the cable THHN 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.
