The performance of cold shrink cable accessories is so superior, will it completely replace heat shrink?
【Abstract】 The cold shrinkable cable accessories have the advantages of small size, convenient operation, rapid operation, no need for special tools, wide application range and few product specifications. Compared with heat-shrinkable cable accessories, it does not need to be heated by fire, and there is no risk of disengagement between the inner layers of the accessories when moved or bent after installation (because the cold-shrinkable cable accessories rely on elastic compression force. ). However, no product is perfect, and cold shrink cable accessories have their own limitations. |
Cold-shrinkable cable accessories have the advantages of small size, convenient operation, rapid operation, no need for special tools, wide application range and few product specifications. Compared with heat-shrinkable cable accessories, it does not need to be heated by fire, and there is no risk of disengagement between the inner layers of the accessories when moved or bent after installation (because the cold-shrinkable cable accessories rely on elastic compression force.).
However, no product is perfect, and cold shrink cable accessories also have their own limitations, which are reflected in:
Firstly, the specifications of the cold-shrinkable cable accessories are limited, and it cannot be made too small, so that the application in low-voltage cable accessories is limited, especially the small square section is almost impossible.
Secondly, it is not suitable for cold shrinkage of oil-immersed cables. It cannot block the oil, which limits the application of cold-shrinkable cable accessories on oil-immersed cables.
Thirdly, its price is about 5-6 times that of heat shrinkable cable accessories, and it will not be the first choice in some economical situations.
From a technical point of view, the performance of cold shrinkable cable accessories is mainly reflected in its partial discharge characteristics, and the comprehensive performance of heat shrinkable cable accessories has certain advantages. In terms of installation, the installation time of cold-shrinkable cable accessories is shorter than that of heat-shrinkable cable accessories, and power can be sent after installation. Cold-shrinkable cable accessories have some advantages. To sum up, it is unlikely that cold shrinkable cable accessories will completely replace heat shrinkable cable accessories. Click to see the difference between cold shrinkable cable accessories and heat shrinkable cable accessories.
Here to remind users: according to their own industrial and mining conditions, to choose the type of cable accessories. Any product exists for a reason, and it is unlikely that it will die out completely. In fact, casting, wrapping and other cable accessories have been used for nearly fifty years, but they are still in use today.
