Hot and cold shrink cable accessories in terms of price, quality, suitable environment what are the difference
cold cable accessories and heat shrinkable cable accessories are products of power cable industry, but from the aspects of price, quality, suitable environment, which has a lot of difference. Therefore, materials of some small make up to you, hope to be of help!
a, shrinkage cable accessories and heat shrinkable cable accessories is the price difference:
1, the heat shrinkable cable accessories products of the price will be cheaper, the current is heat shrinkable products are widely used in the field of below 35 kv, 35 kv level has been gradually to excessive cold, and 10 kv areas and 1 kv because the price is relatively cheap, so it has been widely used.
2, shrinkage cable accessories product price is quite expensive, cold current price of the product is about 4 to 10 times the heat shrinkable products, may also be more, but from the perspective of the operation cost of a long-term, more than 10 kv products can be more consider to choose cold type of cable accessories, in particular, 35 kv, choose the cold can reduce long-term operation cost;
2, shrinkage cable accessories and heat shrinkable cable accessories on quality difference:
1, cold type of product has the advantages of the popularization and use of the cold cable accessories is constantly in high voltage direction development, currently has a 110 kv cold cable accessories.
2, heat shrinkable cable accessories has the shortcoming of the heat shrinkable cable accessories for long periods of wandering in the use of below 35 kv voltage class, and in the 35 kv voltage grade, heat shrinkable type of cable accessories has become a cable in the process of running accidents often happen in one of the important reasons;
3, shrinkage cable accessories and heat shrinkable cable accessories in applicable environment difference:
1, heat shrinkable cable accessories material its elasticity is relatively poor, so a lot of time can lead to partial discharge control is difficult, thermal cycle caused by the aging speed will be faster.
2, cold cable accessory material performance will be good, do not need to heating can be installed. This will make the interface performance can get a lot of ascension, partial discharge is low, long-term, stable and reliable, can with the cable heat bilges cold shrink 'share', long-term and stable working machinery due to thermal aging degree is low, the thermal shrinkage in attachment.
so, hot and cold shrinkage cable accessories in terms of price, quality, suitable environment have many difference, small make up remind here, manufacturers and buyers must be timely identify seriously good, avoid the screened out the parameters of the two kinds of cable products and the difference between a series of problems, resulting in the occurrence of safety accidents.
