35kv Cold Shrink Terminal
Today we are going to talk about Cold Shrink Cable Accessories. 35kv is what we call 26/35kv in our industry. All voltages within this range can be used. 35kv cold shrink terminal head is one of the power cable accessories. There is another type of 35kv cold shrink terminal head, which is 35kv cold shrink intermediate joint. The cold shrink cable terminal head is a component that connects the cable to other electrical equipment, and the cold shrink cable intermediate head is a component that connects two cables. Therefore, the cold shrink cable terminal head and the cold shrink intermediate head are collectively referred to as cold shrink power cable accessories. Next, let's talk about these two types of cold shrink cable accessories separately.
The 35kv cold shrink terminal head is produced with liquid silicone rubber, which integrates waterproofing, stress control, shielding, and insulation. It has the advantages of long service life, easy operation, no need for professional tools, and few product specifications. 35kv cold shrink terminal heads are very popular in high altitude areas, cold areas, humid areas, salt fog areas and heavily polluted areas. It does not require open flames when installing, but relies on its own elastic retraction force at room temperature, so it is also particularly suitable for flammable and explosive places such as petroleum, chemical industry, mining, tunnels, etc.
35kv cold shrink terminal heads are divided into two specifications according to the number of cores: single-core and three-core. Since it belongs to high-voltage cold shrink terminal heads, 35kv cold shrink terminal heads are also divided into 35kv cold shrink indoor terminal heads and 35kv cold shrink outdoor terminal heads. Even though there are differences in the number of cores and types, there is only one type of cable applicable square number, namely: 1# (50-95mm²), 2# (120-185mm²), 3# (240-300mm²).
The main material of the 35kv cold shrink intermediate joint is also liquid silicone rubber. Like the 35kv cold shrink terminal head, it is divided into single-core and three-core specifications, but it is not divided into indoor and outdoor. Its cable applicable square number is also: 1# (50-95mm²), 2# (120-185mm²), 3# (240-300mm²).
The quality of the 35kv cold shrink terminal head affects the safe operation of the cable line, and it is also particularly important during construction operations, so it needs to be carried out in a clear weather, dry air, no flying dust, and no flying paper scraps.
