Underwriters Laboratories lnc.File E 348482长度：自熄套管长度为1000（）毫米（连续长度可由供需双方另议）。
Silicone coated fiberglass sleeving treated at a high temperature is the sleeving braided with non-alkali fiberglass and coated with a special kind of silicone resin. Self-extinguishable fiberglass sleeving possesses good qualities of dielectric,self-extinguishment,excellent softness and elasticity.It is widely used as wiring insulator for H grade electrical machinery,domestic electrical appliances、TV sets、ａnd electric equipments, and also for the protection of collected stands of wire.Now this product has passed UL recognition and the UL File NO,is E 348482.
