Water tree resistant cable

A fire and thermal insulative wrap for protecting building wires and cables is provided comprising a layered construction of a support substrate and a coating, thereon, of an intumescent material. Optionally, a third ceramic layer is provided for added fire protection and electrical properties. Wires and cables constructed to include the wraps are cost effective because construction can include the substitution of low cost polyolefin resins and compounds for fluorocarbon resins and smoke suppressed PVC compounds. The new constructions based on polyolefin components advantageously produce lower levels of smoke and toxic and corrosive gases during a fire event when compared with the halogen based PVC and fluorocarbon systems. Moreover, the superior fire and thermal protection provided adds safety gained from increased circuit integrity. Finally, the wrap thickness being slight does not add significantly to cable size and therefore promotes an installation advantage.
