HEDT is dual wall heat shrinkable tubing. Its inner layer is made from elastomeric insulation material to provide high insulation and the external layer is made from semi- conductive materials to provide electric shielding. The tubing manufactured with special technology, is suitable for applications in power cable joints from 11kV to 36kV.
