Specifications

Coffee and green color fiber glass tube can be used on many electrical equipments, such as mutual inductors,zinc oxide arresters

Coffee and green color fiber glass tube is insulation product shaped through gluing alkali-free and twist-free glass fiber yarn, alkali-free glass cloth and epoxy Volan cloth soaking in epoxy resin compound glue, then being heated and solidified; According to users requirements, it can be made into such heat-resistant grades as B, F or H grade, which have good electrical capability and mechanical strength, and now is widely used in arrester sleeves and bushings of switches on the column for 35KV110KV220KV1000KV etc.
