Cold shrinkage Construction:

A cold shrinkable cable accessories reduce too many human factors. In construction, cold shrinkage can automatically shrink by removing the plastic core inside. In the process of shrinkage, the phenomenon of uneven shrinkage of insulating pipes will not be caused by human factors. Thus ensuring the quality of construction.

B cold contraction is contracted from one end to the other according to the program. This program can not be changed to ensure that no bubbles will appear during the contraction process.

C is dangerous in petrochemical industry. Cold shrink construction avoids the use of heat sources to become safe.

Heat shrinkable Construction:

A thermal shrinkage is greatly affected by the construction level. When heated unevenly, the thickness of insulation pipe shrinks unevenly, and even some parts do not shrink at all, resulting in uneven shrinkage thickness, thin areas are prone to breakdown and other problems.

B In the process of heat shrinkage, it is easy to cause the burning of insulating pipes due to poor control of the degree of heating, which greatly affects the insulation performance of insulating pipes.

C shrinkage can be heated from one end to the other or from the middle to both ends during the heating process, which can easily lead to bubbles in the shrinkage process.

D is a place where the use of open fire and other heat sources is prohibited, such as petrochemical, chemical and other industries. If the use increases the risk, it may lead to serious accidents.

In the process of using

1) With the expansion and contraction of the cable, the cold-shrinkable cable accessories will keep synchronous breathing with the cable, so that the cable and accessories will always maintain a good state of integration.

2) The thermal shrinkable cable accessories will not change with the thermal expansion and cooling of the cable, and long-term operation will easily lead to the gap between the cable and accessories and lead to accidents.

Quality contrast

1) The inherent advantages of cold shrinkage make the application of cold shrinkage cable accessories develop towards high voltage continuously. At present, there are 110 KV cold shrinkage cable accessories.

2) The inherent shortcomings of thermal shrinkable cable accessories make them hovering below 35 KV voltage level for a long time. At 35 KV voltage level, thermal shrinkable cable accessories have become an important cause of frequent accidents in cable operation.
