ABSTRACT:
A fire, heat and high voltage cable wrap system for protecting wires and cables. The protective cable wrap system includes a support layer for strength being selected from the group consisting of woven, non-woven, knitted, netted or matted materials; a high voltage arc resistant layer for protection against high voltage; a fire protective coating layer for protecting the cable wrap system against fire; and a top coating layer for resistance to water, chemicals, gases, environmental factors and mechanical damage. The support layer, the high voltage arc resistant layer, the fire protective coating layer and the top coating layer are laminated together for forming a composite laminate structure having a plurality of concentric layers for the protection of transmission wires, electrical wires and cables that provides for high voltage isolation up to 50 kV.
