The Relationship Between the Specifications of Cold Shrink Cable Accessories and the Cross-Sectional Area of Cables

 

As a mainstream insulation product used in cable terminations and cable intermediate joints, what are the specifications of cold shrink cable accessories? How does it correspond to the size of our cable models? Today, we will come to popularize it for everyone.

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. How should we select the cold shrink accessories? Here it is necessary to affirm that the cold shrinkage cable accessories are mainly applicable to power cables, with YJV22 cross-linked polyethylene insulation vinyl chloride sheath with armored power cable as the representative. Other types of cables, if the structure is too different, is not necessarily used, you need to correspond to see the size of the cable and the structure of the diagram to determine again.

Similarly, our cold shrink accessories are assembled from a variety of types of cold shrink tube, that his application also need to comply with such specifications. That is to say, if our cold shrink accessories are shaped well, there is a certain range of applications. Cold shrinkage terminal for example, cold shrinkage finger sleeve used in the cable stripping position, to play the role of branch core and insulation sheath, cold shrinkage insulation tube used in the main insulation, to play the role of insulation sheath. High-voltage cold shrinkage terminal used in the semi-conductor layer cut away from the location, which has a prefabricated stress cone, can play the role of the main insulation and electric field diversion, sealing tube for the copper terminal sealing protection and phase differentiation role. So we want to determine whether the cold shrink cable accessories are applicable, it is necessary to know whether the size of the applied position in our cold shrink tube effective shrinkage application range and so on. This is the basic principle of selection.

It should be noted that the cable cross-sectional area and cable diameter is not the same thing, need to be converted, the easiest way is to look for cable manufacturers cable manual direct query. The same cable cross-section, different structure types, different manufacturers have certain differences, such as armored and non-armor cable, the outside diameter is different.

After years of experience in the application of products, the above division is very practical and economical to meet the needs of most degrees of power cables. If it is a special cable, you can seek support and specialize in customization.
