High-Voltage Three-Piece Joint Heat Shrink

The EHVS is designed such that it is compatible with polymeric insulated cables independent of the manufacturer and can be adapted with respect to grounding required for various cable constructions.  The installation of the joint can be performed by trained installers using conventional tools. The joint is designed and tested in accordance with IEC 60840.

The joint design consists of a three piece pre-moulded silicon rubber body with 2 adaptors and a main body with integrated stress control. It is factory-tested and 100% routine-tested. Multiple body sizes are available to cover a wide range of applications. Different adaptors can be used in combination with the main body to customize the design for transition joints. A shear-off bolt connector is used to connect the cables and is suitable for both non-milliken and milliken conductors made of either aluminum or copper. The entire design can be modified depending on the type of earthing required - In-line, Shield break, or Grounding. A heat-shrinkable polymeric sleeve containing oil-resistant sealant is designed to encapsulate the entire joint body. The moisture protection comes from the aluminum-lined wraparound, which also provides mechanical protection. 

The outer protection of the joint is customizable as per customer request. The outer protection can also be modified to include a copper case, a glass fiber resin box, or both for heavy-duty protection. The kits are also available with a fiber optic kit and a PD sensor to continue monitoring the cable status.
