ABSTRACT:
Electric arc and flame protective tape for electrical, particularly for high voltage electrical cables and complex electrical, splices, junctures and the like, comprises a base sheet fabric coated with a thermoplastic resin preferably from a liquid polyvinyl chloride plastisol, reinforced and protected against destruction by pre-melting with a filler of heat resistant fiber, and containing flame and fire-retardant plasticizer as well as fire-retardant, preferably intumescent, and heat stabilizing substances. The tape is flexible and elastomeric and may be wrapped about the cable or joint, protectively to further insulate and protect it against electrical arcing, heat or fire.
