MV Cable
MV Cable
(OP)
Does anyone know what is the function of stress-relief-mastic and nested-conductor-tubes in MV (36 kV) cable joints? Thanks for help!

in page 3 pos.7 you can see the nested [3 tubes] used to hold in place the PILC armored cable.
Also in order to deviate the electric field intensity in order to avoid insulation stress a stress relief mastic [SRM] is wrapped on the conductor [as shown].
RE: MV Cable
The three tubes-the smallest is the Black Stress Control Tube, the middle is Red Insulating Tube and the largest Black/Red Dual Layer Tube-are at the beginning "nested" not far from the connection place and will be shrunk one-by-one as indicated. The SRM will fill the voids creating a smooth surface in order to apply the tubes
