Shielded (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
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.
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.
