The 8.7/15–630 kV European-style front connector is suitable for the inlet and outlet cable terminations of ring-main units (for cross-linked power cables). It is bolted to the switchgear’s cable entry/exit bushing bases, the wall bushings of cable distribution boxes, and double-through bushings, and is also applicable to packaged substation equipment.

The 630A European-style rear connector can be connected to a European-style front connector or to another rear connector, thereby providing an extended cable connection circuit (branch). However, it cannot be directly connected to bushing bases or wall bushings. The connector’s tail end can be directly sealed with an insulating plug, or it can be further extended to connect another European-style rear connector or a rear surge arrester.

17/45–50 kV European-style surge arresters provide reliable overvoltage protection for electrical systems. The shielded design of these rear-mounted arresters, featuring an external semi-conductive layer, ensures the personal safety of installation and maintenance personnel as well as the safe operation of equipment. Moreover, their exceptional resistance to ultraviolet radiation, aging, water ingress, and moisture penetration guarantees dependable performance even in harsh environmental conditions. When paired with European-style front-end connectors, these rear-mounted arresters help ensure the secure and reliable operation of the power grid.
