Application Of Cold-shrink Cable Accessories In Insulation In Medium-voltage Systems

In practical applications, the Cold Shrink Cable Accessories is first slid-mounted to the prepared cable end or joint position, then the internal support core is removed, and the accessory body retracts to cover the conductor and insulation layer. This method ensures close contact between the accessory and the cable's outer solid insulation layer, improving the consistency of the overall electric field distribution.

The construction team typically pre-processes the geometry of the cable's outer sheath and insulation layer according to product specifications, ensuring the accessory matches the insulation layer after shrinkage. The materials selected for cold-shrink cable accessories are primarily elastomers such as silicone rubber. These materials have good shrinkage properties at room temperature and can be used in conjunction with the outer solid insulation to complete the encapsulation.
