Product Description

1.Introduction of 24kV heat shrinkable power cable accessories

Heat-shrinkable cable terminals are commonly known as heat-shrinkable cable heads, which are widely used on the terminals of cross-linked cables or oil-immersed cables with voltage levels of 35KV and below. Heat-shrinkable cable intermediate connection is widely used for the intermediate connection of cross-linked cables or oil-immersed cables with voltage levels of 35KV and below. Compared with traditional cable accessories, it has the characteristics of small size, light weight, safety and reliability, and convenient installation.

The product conforms to the GB11033 standard, the long-term use temperature range is -55~105℃, the aging life is up to 20 years, the radial shrinkage rate is ≥50%, the longitudinal shrinkage rate is <5%, and the shrinkage temperature is 110°C~140°C. The products are divided into single core, two cores, three cores, four cores, and five cores, which have been widely used in the terminal processing and intermediate connection of low-voltage cables. The terminal insulation tube is divided into red, green, yellow, black and blue directly. Small size, light weight, reliable performance, widely used in electric power, petrochemical, metallurgy, railway, port construction, and various fields.
