Specifications

Epoxy filament winding tube can be used on many electrical equipments, such as mutual inductors,zinc oxide arresters,etc.

Epoxy filament winding 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.
