Medium Voltage 11kV Cable Joint Demonstration

Remove 1 meter of the Red [Oversheath];to expose the [Armouring] – Single Layer of galvanised circular steel wires – to be cut away.

Insert collar under the [Armouring] and tighten with external collar.

Remove black [Sheath], [Tape Binder], white[Laying up] to expose the copper[Metallic Screen].

Remove black insulation Screen to expose grey insulation.

Repeat for 2nd Cable.

Expose 10cm of the conductor, clean, add insulation and prepare for insulation test.

Insulation test before mechanical connection of cable conductors.


Remember to insert the final Oversheath in the last step before you joint the cable.

Mechanical joint of conductors, with heat shrink insulation and wrap over with braiding tape.
