Product Description:
Continuous busbar protective bushing has excellent flame
retardancy, insulation, thermal stability, and can provide high
insulation strength and resistance to electric carbon marks. Soft
material, good elasticity, more convenient to use. Limit PBB, PBBD,
PBBE and heavy metals and other substances harmful to the
environment, do not produce toxic gases and harmful substances when
burning, suitable for bus and electrical equipment anti-corrosion
and insulation protection. Products are widely used in power
industry, communications, automobiles, ships, aircraft
manufacturing and other fields
Features:
