Joining closures eks-10SK-SL-M and eks-10SK-L-SL-M

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

THE CLOSURE CAN BE MOUNTED IN A PIT, THE LENGTH OF WHICH DOES NOT EXCEED THE LENGTH OF THE CLOSURE

Technical performance

eks-10SK-SL-M and eks-10SK-L-SL-M (cold technology) – joining closures with the use of polyurethane compound, 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. Polyurethane compound;
  4. Kit for connecting the sheaths using a solderless grounding system, which includes a ground wire and spring rings;
  5. Structural material “ArmorCast”;
  6. Installation instructions.

Closure design (eks-10SK-SL-M)

The electric field intensity is equalized with special tapes. The insulation of the junction of the conductors is carried out with the use of heat-shrinkable tubes. The space between the conductors, as well as the space between the conductors and the sheath, is filled with polyurethane 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. The external protection of the closure from mechanical damage is provided by the ArmorCast structural material.

Closure design (eks-10SK-L-SL-M)

The design and installation of the eks-10SK-L-SL-M closure are similar to the previous description for the eks-10SK-SL-M closure.

The distinguishing feature is the protection of the conductor joints - instead of heat-shrinkable tubes, the semiconducting “Tape 13” and the high-voltage self-vulcanizing “Tape 23” are wound in turns.

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-10SK-SL-M and eks-10SK-LSL-M closures are tested in accordance with GOST 13781.0-86.

Characteristics

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

Application

The eks-10SK-SL-M and eks-10SK-L-SL-M joining closures are designed to connect cables with an aluminum or lead sheath, with impregnated paper insulation for 6 and 10 kV voltage, operated at an ambient temperature from -50 С to +50 С, 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.
