Joining closures eks-6SKaT-R

Technical performance

eks-6SKaT-R heat-shrinkable joining closure using rubber compound.
It is used to connect flexible cables with rubber insulation for a voltage of 6 kV.

Closure set includes:

1. Copper sleeves for crimping;
2. Special tapes;
3. Heat-shrinkable tubes with an adhesive layer;
4. Rubber compound;
5. Installation instructions.
   
   

Closure design

The cable conductors are connected with copper sleeves for crimping. The electric field intensity around the conductor connection is equalized with special heat-shrinkable tubes.
The restoration of the semiconductor coating of the core is carried out by a special semiconducting tape.
The inner space of the closure is filled with rubber compound, which provides the following:

1. 100% air displacement from the closure;
2. Sealing of connected cores;
3. Necessary mechanical strength and closure tensile strength, as well as strength against short-circuit shock currents.

The compound is poured into a plastic case, which is removed after polymerization of the compound.

Technological features

• test voltage is supplied immediately after installation;
• mechanical abrasion resistance and flexibility, not inferior to a single piece of cable;
• no special tools required.
  
  

Testing

eks-6SKaT-R joining closure is tested in accordance with GOST 23286-78.

Application
