Joining closures eks-10STT-SL-M

For 3-core cables with impregnated paper insulation for 6 and 10 kV voltage.

Technical performance

Heat-shrinkable joining closures eks-10STT-SL-M with the use of plastic compound are used for cables with aluminum or lead sheath, with impregnated paper insulation, for 6 and 10 kV voltage.

Closure set includes:

  1. Universal connectors with breakaway head manufactured by GPH;
  2. Special tapes;
  3. Heat-shrinkable tubing and cable sleeve joints with adhesive layer;
  4. Plastic compound;
  5. Kit for connecting the sheaths using a solderless grounding system, which includes a ground wire, spring rings and contact plates;
  6. Installation instructions.

Closure design

The electric field intensity around the conductor joints is equalized using special mastics with high dielectric constant and sealed with heat-shrinkable tubes. The equalization of the electric field intensity in the cable sheath end is made with the use of special tape with high dielectric constant. The space between the conductors, as well as the space between the conductors and the sheath, is filled with plastic compound, which provides sealing of the connected conductors and blocking the oil-rosin composition, as well as the necessary resistance of the closure against shock short-circuit currents. External protection and sealing are provided by a heat-shrinkable tube with an adhesive underlayer. The closure is protected from mechanical damage by a thick-walled heat-shrinkable casing.

Technological features

  • processing of the space between the conductors in the cable sheath end is not required;
  • test voltage is supplied immediately after installation;
  • admissible height difference along the cable length is 25 meters;
  • no special tools required.

Testing

eks-10STT-SL-M joining closure is tested in accordance with GOST 13781.0-86.

Characteristics

eks-10STT-SL-M joining closures correspond to ST TOO 143-1930-10-16-26-2012 and meet the requirements of GOST 13781.0-86.

Additional advantage

The joint always remains flexible and can be filled thanks to the plastic compound.

Application

The eks-10STT-SL-M joining closure is designed to connect cables with an aluminum or lead sheath, with impregnated paper insulation for voltage up to 6 and 10 kV, operated at an ambient temperature from -500С to +500С, with a relative air humidity of up to 80 %, in cable structures or in the ground.

Supply

At the customer’s request, the sets can be supplied without sleeves or with sleeves for crimping for copper or aluminum conductors.

Cable type

AABG, ASBG, SBG, AABlU, ASBlU, SBN, AASHvU, AASHp, AAB2lSHvU, ASB2lSHvU, SB2lSHv, SBlU etc.
