Cold shrink cable accessories are cold shrinkage stress control tubes, and Suzhou Feibo's cold shrink products have a withstand voltage rating from low voltage 0.6KV to high voltage 35KV. The 1KV rated low voltage cable accessory uses a cold shrink insulating tube as the reinforced insulation, and the 10KV high voltage rating uses a joint cold shrink insulation with a semi-conductive shield inside and outside. The cold shrink branch sleeve is adopted at the fork of the three-core cable attachment of the terminal.
 
Compared with heat shrink cable accessories, cold shrink cable accessories have small sizes, small product specifications, and no need for tools to install quickly and easily. When you use it, you only need to pull out the inner white plastic support bar to shrink the wrapped cable to complete the installation. Because the raw material silicone rubber material itself has a high elasticity, which makes it have a very large radial pressure, the
waterproof seal of the cold shrink cable accessories is not worse than the heat shrinkable product.
 
Cable accessories are the guarantee for the safe and stable operation of cable wires. Today we will talk about the reasons and principles of
waterproof seal of the cold shrink cable accessories.
 
The reasons for the
waterproof seal of the cold shrink cable accessories: 1. Cold shrink cable accessories, especially cold shrink outdoor terminals, must withstand the harsh external environment in the long-term outdoor wind and rain environment, so as to provide protection for the cable. 2. There are many cases where the cold shrink cable joint is immersed in water for a long time, so it must be waterproof and sealed. 3. Moisture have always been one of the main causes of the most harmful damage to cable accessories. Once the moisture enters the inside of the cable, it will affect the insulation and cause abnormal operation to break the cable accessories.
 
So how is the
waterproof seal of the cold shrink cable accessories achieved? Since the cold shrink cable accessory has a very large radial pressure body, it has excellent waterproof performance, and the cold shrink product also uses a silicone rubber self-melting tape and a unique built-in waterproof sealant design to provide an excellent seal. Suzhou Feibo's cold shrink package is also equipped with auxiliary tools such as waterproof tape, so the waterproof seal of the cold shrink cable accessories is trustworthy.
