How to Splice a High Voltage Cable

How to Splice a High Voltage Cable - Step by Step!

Join us as Elektrikerpodden visits our service technician, Stefan Eklund, who walks through the different steps of splicing a 12 kV high voltage cable (3X150 square mm).

Proper insulation and sealing are crucial to prevent moisture intrusion and thus corrosion or short circuits. Inadequate insulation can lead to current leakage and the risk of fire or equipment damage. In this episode, we cover:

• Reference line
• Turning
• Stripping insulation
• Yellow mastic strips
• Heating the stress control tube
• Installing screw splice connectors
• Cleaning screw splice connectors
• Heating shrink tubing
• Copper mesh
• Outer sheath

After completing the splice, it is important to carefully inspect the connections for any errors or deficiencies. This includes measuring resistance and performing insulation tests to ensure the splice is functioning as intended.

Continuously updating and training in the field, both technically and practically, reduces the risks of personal injury, short circuits, and system outages.
