Heat shrinkable cable terminations operating at medium voltage 20 /24 kV. Our range consists of one and three core cable terminations capable of operating indoors and outdoors. They are insulated with PVC, XLPE and PE polymeric cables and are fully tested in accordance with IEC 60502-4.
The medium voltage heat shrinkable cable terminations feature easy installation and reliable stress control. Also, excellent corrosion resistance as well as UV and weathering resistance. In addition, they feature anti – tracking properties. Their electrical and mechanical properties are superior to others in the market which defines them as the best choice for your installation.
