The Heat Shrink Joint (EHVS-H) is based on a heat shrink design for voltage classes up to 72.5 kV. Polymeric insulated cables of various designs can be adapted with respect to shielding and metal sheath.
Our heat shrink cable accessories have been used by utilities and industrial companies around the world for more than 35 years. This ongoing field experience has made TE a leader in materials science and technology for high voltage applications. TE’s materials technology is at the core of the development of our heat shrink joints. The materials used in our cable accessories have been extensively optimized with respect to product design and function, manufacturing and expected service environments. The system is suitable for paper and polymeric cable constructions, and is also designed to accommodate modern jointing requirements such as mechanical shear bolt connectors.
The conductive outer layer together with the insulating middle layer represents the heat-shrinkable hold out for the inner elastomeric layer of the joint body. During the shrinking process, the stored recovery force of the elastomeric layer is released. Combined with the recovery force generated by the heat-shrinkable outer layers of the joint body and outstanding ability of geometrical adjustment, the resulting high-compression force provides tight electrical interfaces and a high-performing seal against moisture ingress.
