The role of cable terminals

remember previous let's small make up to introduce the cable termination the role of the head? For details, please click on 'what role cable terminal head'. So in this article, let's say, the end of a cable in general cable terminal can according to raw material points can be divided into heat shrinkable cable terminal and the cold shrink cable terminal, in accordance with the pressure are rated words can be divided into 1 kv, 10 kv, 35 kv cable termination.

the first, let's talk about the function of cable terminals for the hot and cold shrink cable terminal, cold cable terminal is made out of silicone rubber raw materials, with its products through a series of processing technology of cold in construction is brief, convenient to operate, convenient wait for a characteristic. Construction personnel in the operation is only need the white plastic tube support quietly extraction, the cold cable termination will depend on itself tightly wrapped in a quilt of high elastic to make objects. Then also can make the cable more safe operation directly.

second, heat shrinkable cable terminal is not the same as the cold cable terminal, heat shrinkable cable terminal it is made of raw materials such as PE, polyolefin, its operating technique is the need to use the heating tool make its heat contraction and tightly wrapped in a quilt on the object, then the bedding bag object anticorrosive effect for preventing leakage of insulation protection.

the brief introduces the effect of the end of a cable under hot and cold shrink cable terminal, the basic content of the next us under the effect of 1 - the end of a cable 35 kv what are the hot and cold shrink cable terminal specifications.

1 kv, 10 kv, the application of the hot and cold shrink cable terminal head square is the same, such as 0 # 10-1 kv 16平方毫米,1 # 25 - 50平方毫米,2 # 70 - 120平方毫米,3 # 150 - 240平方毫米,4 # 300 - 400mm2。 10 kv has 1 # 25 50平方毫米,2 # 70 - 120平方毫米,3 # 150 - 240平方毫米,4 # 300 - 400mm2。 They are two different 1 kv hot and cold shrink cable terminal has a single core, two core, three core, four core, five core, and 10 kv hot and cold shrink cable terminal has a single core ( Indoor/outdoor) , three core ( Indoor/outdoor) 。

10 kv in specifications with the hot and cold shrinkage of the 35 kv cable termination is consistent, but apply square is inconsistent, 35 kv cold for square have 1 # 50 - the end of a cable 95平方毫米,2 # 120 - 185平方毫米,3 # 240 - 400mm2; 35 kv heat shrinkable cable terminal for 1 # 50 - square 120平方毫米,2 # 150 - 240平方毫米,3 # 300 - 500mm2。

small make up here focuses on the low pressure hot and cold shrink cable termination due to low stress levels of cable terminal, it is not divided into indoor and outdoor, but 10 kv, 35 kv, hot and cold shrink cable terminal is high stress levels of cable terminal, is a indoor field. Because the cable is divided into indoor and outdoor, with difference can more performance effect - the end of a cable — Protect cable safe continuous operation. Terminal at the end of the power cable line, it besides a sealing effect of power cable, also can improve the electric power cable end, together with other power transmission and transformation equipment or appliances ( Such as overhead lines, switches, etc. ) The connection.
