The relationship between the specifications of cold shrinkable cable accessories and the cross-sectional area of the cable

2023-03-13
First of all, we know that there are actually many kinds of cables, different voltage levels, different structures, different uses, different cross-sectional areas and so on. Cold shrinkable cable accessories are mainly applicable to power cables, which are represented by YJV22 crosslinked polyethylene insulated vinyl chloride sheathed and armored power cables. For other types of cables, if the structure difference is too large, check the cable size and structure diagram.

Cold shrinkable cable accessories are assembled from a variety of types of cold shrinkable tubes, that his application also needs to comply with such specifications. That is to say, we have a certain range of application if the cold shrinkable cable accessories is finalized. Take the cold shrinkable termination as an example, the cold shrinkable breakout is used in the cable stripping position, to play the role of branch core and insulation sheath, cold shrinkable insulation tube in the main insulation, to play the role of insulation sheath, high pressure cold shrinkable termination head used in the semi-conductive layer cut away position, there is a prefabricated stress cone, can play the role of main insulation and electric field dredding, sealing tube for copper terminal seal protection and distinguish. 

So we want to determine whether the cold shrinkable cable accessories are suitable, we need to know whether the size of the applied position is in the effective shrinkage application range of our cold shrinkage tube, which is the basic principle of selection.

It should be noted that the cable cross-sectional area and cable diameter are not the same thing, which need to be converted. The easiest way is to find the cable manufacturer's cable manual and inquire directly. The same cable section, different structural types, different manufacturers have certain differences, such as armored and unarmored cables, the outer diameter is different.
