Busbar Protection Polyolefin Heat Shrink Tubing Tube Wire Wrap Sleeve
Dimenstion
1) 1KV Bus Bar Protection Heat Shrinkable Tube
3) 35 KV Bus Bar Protection Heat Shrinkable Tube
|
Bus-bar heat shrinkable protection tube adopts cross-linked and environmental friendly polyolefin material. It restricts the hazardous substance in PBB, PBBD, PBBE and other heavy metal, and supplies high dielectric strength and voltage withstand performance. It prevents bus-bar from chemical corrosion effected by strong acid, alkali, salt etc. It also has environmental friendly, flexible, flame retardant, soft performance.
It is mainly used in dielectric and mechanical protection, joints and terminals.
Shrink temperature: 84ºC ~ 125ºC
Environmental, flexible, flame retardant, soft
