The development of new energy in China is now on the fast track, and wind power generation accounts for a significant share of it. Many wind farms are built on the grasslands of Inner Mongolia, and the 35kV collector lines of wind farms are laid using direct burial cables to protect the grassland vegetation and the overall appearance of the grassland. From the operation situation, the cable intermediate head has the phenomenon of discharge.
Cold-shrinkable cable accessories are a kind of prefabricated cable accessories that can be constructed at room temperature without heating. The cold-shrinkable power cable accessories are made of imported liquid silicone rubber. After installation, they always maintain a proper radial pressure on the cable body. The interface characteristics are relatively good, and there will be no creepage breakdown due to cable operation. The stress control part is integrated with the main insulation, which effectively solves the problem of electric stress concentration at the outer shielding section of the cable and ensures reliable insulation. It is a very important cable accessory.
Cable accessories refer to the intermediate connections and terminal connections of various cables in the cable line, which together with the cables form a power transmission network. With the continuous development of cable manufacturing technology, cable accessories have gone through several stages, such as cast cable accessories, wrapped cable accessories, heat shrinkable cable accessories, prefabricated cable accessories and cold shrinkable cable accessories. At present, the most widely used are heat shrinkable cable accessories, prefabricated cable accessories and cold shrinkable cable accessories. Next, let’s take a look at it in detail.
The Difference Between Cold Shrink Termination and Heat Shrink Termination:
1. The difference between the ground wire connection methods: Cold-shrinkable cable accessories use constant force springs. The heat shrinkable cable accessories need to be soldered when using a ground wire.
2. The difference of the shrinkage method: The plastic support strip of the core part of the cold-shrinkable cable accessory shrinks naturally. The heat-shrinkable cable accessory needs to be heated by fire to shrink the low-voltage cable termination.
