The medium voltage 1-core cold shrink joint is a cold shrink accessory used in medium voltage cable systems (usually voltage levels of 6kV to 35kV). It is specially designed for the connection of single-core cables and provides a reliable connection and insulation protection solution for medium voltage single-core cable systems.
