Cable

Connecting sleeve for 1 kV armoured and unarmoured 3, 3½, 4 and 5 core cables with plastic insulation.
Ex: NAYY, NAYBY, AXPK, BBΓ, ABBΓ.

Connecting sleeve construction

For cables without armour

The connecting sleeve consists of one outer and four or five inner heat shrink tubes. The connectors shall be insulated and sealed by thick-walled tubes with a thermoplastic adhesive coating on the inner surface. The same thick-walled heat-shrink tubing with a larger diameter also provides external protection and sealing of the coupling. All couplings shall be designed in such a way as to maintain the possibility of crossing the cores during phasing. When ordering couplings without couplings, care shall be taken to ensure that the couplings used, either pressed or bolted, do not exceed the maximum dimensions given in the tables.

For cables with steel strap armour

The coupling shall consist of one outer and four or five inner heat-shrink tubes as well as copper mesh and contact springs. The connectors shall be insulated and sealed by thick-walled tubes with a thermoplastic adhesive coating on the inner surface. The copper mesh is wrapped around the splice area and its ends are connected to the armouring of the steel strips by contact springs, thus ensuring mechanical protection of the sleeve and electrical contact between the armouring of the cables to be connected. External protection and sealing of the sleeve are provided by a thick-walled Thermo shrink tube. All couplings shall be designed in such a way as to maintain the possibility of crossing the cores during phasing. When ordering couplings without couplings, care shall be taken to ensure that the couplings used, whether pressed or screwed, do not exceed the maximum dimensions given in the tables.
