Shielded (Unshielded) Top-Expansion Busbar

MengziShielded (Unshielded) Top-Expansion Busbar

Shielded flexible busbar connectors are used for busbar connections between SF6-insulated metal-enclosed switchgear. They provide fully sealed and fully insulated connections between load switches and busbars, completely eliminating the fatal risks associated with high-voltage conductors being exposed to harsh weather conditions. In addition, they are easy to install and offer high reliability.

Product Description

　　Product Overview

　　The busbar connector is composed of a busbar combined with T-shaped and cross-shaped connectors. The busbar length can be custom-made anywhere between 300 mm and 800 mm, making it suitable for electrical systems rated at 8.7/15 kV to 12/24 kV with rated currents of 630 A or 1250 A. The bushing interfaces comply with DIN 47636, EN 50180, and EN 50181 standards.
