Straight cable joints for screened rubber insulated cables with three service cores and three protection cores 6/10 kV

Straight cable joints for screened rubber insulated cables with three service cores and three protection cores 6/10 kV


Application: for joining mining wires of type: NTSCGEWOU, OnGcekgż-G (S), OnGcekgż-G (Z), OnGcrekgż-G (S), OnGcrekgż-G (Z) 6/10kV.

Tinned mining connectors are used for joining service cores and protection cores. Stress control mastic is wrapped around the screens’ terminations and the connector’s surface. They are 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 and outer semiconducting. Heat shrink thick wall adhesive-layered flame-retardant tube is used for reconstruction of the outer covering. Protection against moisture penetration is guaranteed by applied both thermofusible adhesive and mastic.
 

Properties of the joints:

  • guarantee durable wires’ connection thanks to threaded mining connectors,
  • cover cable cross-sections up to 185 mm2 of service core and up to 95 mm2 of protection core,
  • thermoplastic stress control mass applied in the joint set prevents from incomplete discharges occuring,
  • high electrical and mechanical durability, resistance to difficult working conditions such as opencast mines,
  • guarantee reliable and long-life work of the power line,
  • anti-moisture barrier in the form of insulation and filling masses.

Positive technical approving issued by Institute of Power Engineering in conformity with requirements of norm PN -HD 629.1 S2:2006.
