Overview of Heat Shrink Cable Accessories

Overview of heat-shrinkable accessories

The key technical issues in its use are:

To ensure that the electrical parameters of the stress tube must meet the specified values of the above standards, it can work safely.

In addition, attention should be paid to filling the air gap out of the fracture of the insulating semi-conductive layer of the cable with silicone grease to remove the gas and reduce the partial discharge.

The cross-linked cable of heat-shrinkable accessories will shrink greatly during operation due to poor internal stress treatment. Therefore, when installing accessories, pay attention to the overlap between the stress tube and the insulation shield by no less than 20mm, so as to prevent the stress tube from detaching from the insulation shield during shrinkage.

Due to the small elasticity of heat-shrinkable accessories, air gaps may occur at the interface when they expand with heat and contract with cold during operation. Therefore, sealing technology is very important to prevent moisture from infiltrating.
