Structure
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.
Usage
It is mainly used in dielectric and mechanical protection, joints and terminals.
Characteristics
- Shrink temperature: 84ºC ~ 125ºC
- Environmental, flexible, flame retardant, soft
Standard
1) GB/T 1059-2007 2) RoHS approval
