XHH/XHHW-2 Building Electrical Copper Wires is suitable for most current wiring solutions for residential, commercial and industrial applications. Because of its excellent response under overload and short-circuit situations, it is used in service entrance even underground installations. The XHH conductor is able to work properly up to 90ºC in dry environmental conditions. Its insulation is flame retardant, besides, it provides mechanical resistance against to humidity, chemical agents and oils. Its black pigmentation resist very well the ultraviolet sun light, therefore it could be used with no issue in outside applications. Conductors certified with suffix ´´-2 ´´, as XHH-2, these can meet a continuous operation temperature of 90ºC(194ºF) in dry or wet conditions
