Straight cable joints for single-core screened polymer insulated cables with copper wire screen

Straight cable joints for single-core screened polymer insulated cables with copper wire screen

Application: for joining cables of type: N(A)2XS(2)Y, N(A)2XS(F)(L)(2)Y, YH(A)KXS, XUH(A)KXS, XH(A)KXS , X(RU)H(A)KXS.

The set contains stress control mastic which is wrapped around the screens’ terminations and the connector’s surface.
It is used for preliminary controlling of the electrical field and filling up the space between insulation and connector’s endings. The joint is supplied with stress control tubing which is shaping the electromagnetic field distribution on the whole connection length, insulation and double-layer tube with integrated layers: inner insulation, outer semiconducting. Outer semiconducting layer reconstructs the cable’s screen and increases the insulation layer’s pressure strength. This design guarantees the perfect adhesion of all tubes in the joint. Copper mesh applied on the whole joint length increases the mechanical resistance of the joint and improves the heat venting from the drain wire.
Drain wire is being connected by screw or compression connectors additionally protected by the heat shrink tube. Reconstruction of the cable jacket is made by heat shrink thick wall adhesive-layered tube guaranteeing good adhesion of the tube to the cable’s outer surface.
Plastic mass applied at the joints endings protects against moisture penetration.

Properties of the joints: 

  • for cables with cross-sections up to 400 mm2 (concerns joints with screw connectors),
  • in case of joints with screw connectors they limit the number of tools necessary for the assembling,
  • thermoplastic stress control mastic applied in the joint prevents from appearing of the incomplete discharges,
  • high electrical and mechanical resistance,
  • guarantee reliable and long-life work of the power line,
  • short assembling time thanks to simple construction and attached installation guide,
