Joints 110 kV
Technical description
Pre-moulded outdoor joint MCB 126 / 145 is designed to connect two XLPE 64/110 kV high voltage cables. Joint MCB 126 / 145 could be produced in di erent constructions which give the possibility of screen wires direct connection, cross-bonding connection of di erent cable phase wires screen (screen transition), wires screen connection with optical fibers in the metal tubes (modules).
Marking of high-voltage cable joints
