초록 ▼

Electric arc and flame protective sheath or boot material for electrical, particularly for high voltage electrical, cables and complex electrical splices, junctures and the like, is precast preferably from a liquid polyvinyl chloride plastisol, preformed into a selected shape of a protective sheath or boot, reinforced and protected against destruction by pre-mixing with a filler of heat resistant fiber containing flame and fire-retardant plasticizer as well as fire-retardant, preferably intumescent, and heat stabilizing substances. The precast sheath or boot is flexible and elastomeric and may be sized and shaped to be slipped upon the cable or joint protectively to further insulate and protect it against electrical arcing, heat or fire.

대표청구항 ▼

A precast electrical arc and fire protective sheath, boot or the like in the form of a separately manually mountable protective unit for disposition about electrical equipment, cables, cable splices, appurtenant equipment or the like, said unit comprising a heat fused, and molded thermoplastic base having evenly distributed therein a heat resistant fiber, heat stable above the melting point of said thermoplastic base, and fire-retardant substances, said fiber adapted to hold heat molten thermoplastic from flowing, said unit being molded from a suspension containing no water other than chemically bound water, said fire-retardant substances being heat activatable at high arcing and flaming temperatures to release fire protective gases to convert said protective unit into a foamed heat insulating coating when mounted about electrical equipment, such as cables, cable splices, appurtenant equipment and the like.
