20kv European Front Connector European Standard Cable Accessories Connectors
Type: HT-15KV / 630A front joint
Application
* Non-Shielded front / rear connector can be used in 20kv cable branch box, ring main unit, box transformer substation, etc.,
guaranteed that the product can be multi-branch power supplied.
* Applicable to fully enclosed connection to Φ46 / Φ56 / 91.5 / M16
* For 18/20kv, 12/20kv crosslinked cables, cable cross-section 25-400mm.
Features
* Product frequency withstand voltage and partial discharge are higher than standard IEC60502 of 30%.
* It is the product with fully insulation, fully enclosure, fully shielding.
* After connection of front connector and rear connector, the center distance is only 100mm, not only meet the space need
in gas type ring main unit, also smaller the structure of cable branch box.
