0 likes
China [CN] 
MP-35KV heat shink busbar sleeve, known as copper bar protection tube, is made of cross-linked environmental protection polyolefin PE heat shrinkable materials which is bombarded by high power electron beam. The product with good resistance to bending and scratching, high insulation strength and resistance to electric carbon mark, applies to switchgear, substation bus, busbar, electrical equipment for anti-corrosion and insulation protection. It’s widely used in electric power industries.
Features & Benefits:
1, resistance to flame and corrosion.
2, with superior insulated and chemical properties.
3, Shrink ratio: 2:1 (1 kV, 35 kV, 10 kV busbar )
4, environmental friendly, high strength, good elasticity, flame-resistant, soft.
Operation Indexes:
Min. Shrink temp.: 80℃
Final shrink temp.: ~120℃
Operating temp.: -55℃~125℃
Up to standard: Approvals
