Transition cable joints from 3-core screened saturated paper insulated and armoured cable with common metal sheath to three single core extruded and screened polymer insulated cables with copper wire screen

Transition cable joints from 3-core screened saturated paper insulated and armoured cable with common metal sheath to three single core extruded and screened polymer insulated cables with copper wire screen


Application: for joining cables of type: NH(A)KBA, NH(A)KY, H(A)KnF(t, p)A, H(A)KnF(t, p)y, H(A)Kny with cables N(A)2XS(2)Y, N(A)2XS(F)(L)(2)Y, YH(A)KXS, XH(A)KXS, XUH(A)KXS, XRUH(A)KXS.

In the initial stage of preparing for the assembling, paper insulated cable is transformed into polymer insulated cable with the use of transparent heat shrink thin wall tubes and 3-core breakout boot. Cores are being joined by leakproof connectors with partition. The joint set contains stress control mastic and tubing which are applied for controlling of the electrical field on connectors, individual cores’ screens terminations and metal sheath.
Insulation tubes increase the electrical resistance of the construction, double-layer tubes reconstruct the individual cores’ screens. Spring clips guarantee the proper connection of the polymer cables’ copper wire screen with the metal sheath and armour of the paper cable. Full protection against moisture penetration is ensured by heat shrink thick wall adhesivelayered tubes for the jacket reconstruction, heat shrink 3-core breakout boot closing the connection from the side of polymer cables and insulation mastic.

Properties of the joints:

  • universal application for cables of two voltage levels: 8,7/15kV i 12/20kV,
  • resistant to difficult environmental conditions, full protection against moisture penetration, can work under water,
  • in case of joints with screw connectors they limit the number of tools necessary for the assembling,
  • guarantee reliable and long-life work of the power line,
  • high electrical and mechanical resistance.
