Product Description

Bus-bar heat shrinkable protection tube
Model number: SB-WMPG SERIES
Operation temperature:-55ºC-125ºC
STRUCTURE
Bus-bar heat shrinkable protection tube adopts cross-linked and environment friendly polyethylene 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.
USAGE:
Usage:Use in dielectric and mechanical protection, joints and terminals.
Application range: Electrical
CHARACTERISTICS:
Shrink ratio:2:1(1kV,35kV),2.5:1(10kV)
Shrink temperature:84ºC~125ºC
Operating temperature:-55ºC~125ºC
Environmental, Flexible, flammable, and soft

STANDARD
a. GB/T 1059-2007                     
b. Environment certificate:ROHS
