Joining closures eks-10HH-3-M and eks-10HH-3-А-M

For 3-core cables with insulation of vulcanized (cross-linked) polyethylene for a voltage of 10 kV.

MAIN HEAT-SHRINKABLE CLOSURE INSTALLATION TECHNOLOGY

Technical performance

eks-10HH-3-М and eks-10HH-3-А-М – heat-shrinkable joining closures.

Closure set includes:

  1. Universal connectors with breakaway head manufactured by GPH;
  2. Special tapes;
  3. Heat-shrinkable tubing;
  4. Kit for connecting the shield and armor using a solderless grounding system, which includes a ground wire and spring rings;
  5. Installation instructions.

Closure design

The electric field intensity at the section of the semiconducting layer of the current-carrying conductor is reached with special tapes. To restore the insulation of the current-carrying conductor, after removing the semiconducting layer, a heat-shrinkable tube with an adhesive layer is used. Conductor connection is carried out with the use of connectors with breakaway head. The electric field intensity around the conductor connection is equalized with mastic and heat-shrinkable tubes.

Insulation and sealing of joints is made with the use of heat-shrinkable tubes with an adhesive layer. The cable sheath is restored using a heat-shrinkable tube.

Installation

  • cable preparation is carried out in accordance with the installation instructions for the termination;
  • To remove the semiconducting layer from the core insulation, using special tools is recommended.

Technological features

  • test voltage is supplied immediately after installation.

Characteristics

eks-10НH-3-М and eks-10НH-3-А-М closures correspond to ST TOO 143-1930-10-16-26-2012 and meet the requirements of GOST 13781.0-86.

Application

eks-10НH-3-М and eks-10НH-3-А-М – heat-shrinkable joining closures are designed for connecting 3-core cables with cross-linked polyethylene insulation, with a PVC sheath, armored with steel tapes or wires*, for voltage of 10 kV operated at ambient temperature from -50 C to +50 C, with relative humidity up to 80%, in cable structures.

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

For 3-core cables of the following makes: (manufactured in Russia): APvEp-6/10, APvEgP-6/10, APvEgaP-6/10, PvEP-6/10, PvEgaP6/10, PvEgP-6/10, etc.
