Product Introduction
The external insulation of the composite termination is composed of a glass fiber reinforced epoxy resin tube and a silicone rubber rainshed, aluminum alloy flanges with strong corrosion resistance are installed at both ends. It is the best substitute for porcelain covers and has gradually been accepted all over the world.
