Product features
The 630 A rear plug-in cable connector is used in conjunction with the front plug-in cable connector product. It provides branching for 630 A circuits but cannot be directly connected to products such as bushings. Its rear end can be sealed with an insulator or extended to connect another rear plug-in cable connector and rear plug-in arrester.
Utilizing advanced rear injection technology, the outer layer features a semi-conductive shielding layer that is touch-safe, ensuring personal safety. The unique stress cone structure effectively dissipates electric field stress, resolving electric field stress issues at the cut-off point of the cable shielding layer. It offers expandability, flexible installation and removal, and enables T-type cable connections. The product is fully sealed, fully insulated, fully protected, maintenance-free, submersible-resistant, and pollution-resistant.
