6kV CABLE JOINTS
6kV CABLE JOINTS
(OP)
Are cable joints common practice on HV cables? I have a long run of 6kV cable carrying less than nominal load that has developed a fault mid stream. I normally prefer to re-run damaged HV cables but it is not cost or time effective in this scenario.
What sort of documentaion or procedure is there in splicing HV cables?

lets have some details , eg,paper/lead/xlpe/epr
above or below ground,why it failed etc
RE: 6kV CABLE JOINTS
Cables are pretty old (32yrs) SIEMENS's cables NYFGbY run above ground where :
NY= Protodur Insolation
F = Armour of Galv. Flat Steel Wires
Gb= Helix of Galv. Steel Tape
Y = Protodur Sheath
Replacement length is around 400 meters. A bit of cable 'chaffing' occurred at a bend along the cable tray route.
RE: 6kV CABLE JOINTS
i not heard of protodur,is it a
plastic,rubber or paper insulation and what type of screening does it use?
when you contact a contractor it would be usefull to
have a sample so that a suitable joint can be found

The electrical infrastructure one of our plants in Guinea is very old and has some unorthodox equipment. I guess I am not old enough to recognize some of them!!!!
However,
I found a solution to the old HV cable issue using a Raychem product
