Product Description

Cable accessories of both heat and cold shrinkable type with Features

• Power Cable Termination Technology: Stress Cone
• Power Cable Termination Voltage Class(kV): ≤ 42
• Cable Shield Style: Copper wire, copper tape
• Number of Cores: 1, 3
• Application Type: Indoor
• Industry Standards: Design Specification GB/T 12706.4, IEC 60502-4

Characteristics

• Easy/convenient installation: Stress cone wholly composed inside the silicone rubber body greatly releases the electric stress at the screen cut edge. Pre-expanding with removable plastic spiral tube inside, the elastic silicone rubber body will shrink automatically and tightly onto the needed position by removing the plastic spiral tube without heating or special tools.
• Reliable insulation: Adopting Germany liquid silicone rubber, serving the utilities and industry successfully for 20 years.
• Superior moisture sealing: Triplex sealing design and hydrophobic performance of silicone rubber ensure environmental stability.
• Safety for installing fault: Considerate design reduces the incidence of installing faults which likely occur.
• Wide usage: Possessing a series of superior performances, the cold shrink accessories can be widely used in various regions, especially fire forbidden area, high sea level, cold weather, high-humidity, salt-fog and heavy polluted regions.
