The medium voltage 3-core cold shrink cable intermediate head is specially designed for the connection of three-core cables (usually refers to the voltage level of 6kV to 35kV). It relies on the pre-expansion characteristics of the elastic material. When installing, the support tube is pulled out to automatically shrink the material, tightly wrap the cable connection, and provide reliable electrical insulation, mechanical protection and environmental sealing.

Provide reliable electrical insulation to prevent short circuit or leakage at the cable connection, and avoid insulation breakdown caused by local electric field concentration.
Tightly wrap the cable connection to prevent water, moisture, dust and other pollutants from entering.
Provide mechanical support to prevent the cable connection from being damaged by external forces; able to withstand mechanical stress such as vibration, bending and stretching during cable operation.
Easy installation: No heating or complex installation tools are required, and the installation process is safe and fast.
