35kV-630A European touchable front connector
application:
35kV 630A screen-type electric front connector is suitable for power plants, power distribution equipment and high-voltage power centers with industrial frequency AC voltage of 35KV and below, such as: electric connections, couplings, wind power and the entry and exit of GIS systems. The docking order is now full, full sealed, and full screen. The product adopts the internationally advanced back-fired insulation layer technology, and its electrical performance reaches the international leading level, making it safer and more reliable to use. The installation conditions are not affected by the environment, anti-condensation, anti-pollution, and maintenance-free. The product stress treatment introduces international advanced technology, and the product structure is small in size, fully meeting the installation space requirements. It is an internationally leading prefabricated cable head, suitable for cable cross-sections 50-500mm².
