VSY1-40.5GD Indoor High-Voltage Vacuum Circuit Breaker

The VSY1-40.5GD indoor high-voltage vacuum circuit breaker is a next-generation product specially designed by our company for wind and photovoltaic applications. It is suitable for three-phase AC systems at 50 Hz with a system voltage of 35 kV, where it serves to switch load currents, overload currents, and short-circuit currents. It is particularly well suited for 40.5 kV packaged substations, providing control and protection for transformers with ratings of 3150 kVA and above, and can also be used in other standalone units within 35 kV systems. It is especially ideal for operation in regions characterized by extremely low temperatures, severe pollution, and high humidity.

VGY2-40.5GD Indoor High-Voltage Vacuum Circuit Breaker

The VGY2-40.5GD indoor high-voltage vacuum circuit breaker is switching equipment designed for 35 kV power systems, serving as control and protection devices in industrial and mining enterprises, power plants, and substations. This vacuum circuit breaker boasts superior performance and is particularly well suited for applications involving frequent operations or repeated interruption of short-circuit currents. The circuit breaker features an integrated design that combines the operating mechanism with the main body, arranged in a front‑to‑back split configuration, and incorporates reliable interlocking functions. It can be installed as a fixed unit or configured as a handcart unit when mounted on a chassis.

VGY1-40.5 Series Indoor High-Voltage Vacuum Circuit Breaker

The VGY1‑40.5 series indoor high‑voltage vacuum circuit breaker is an indoor switchgear rated for a three‑phase AC system with a nominal voltage of 40.5 kV. It is suitable for control and protection of electrical equipment in industrial and mining enterprises, power plants, and substations, and is particularly well suited for applications involving frequent operations or repeated interruption of short‑circuit currents. The circuit breaker features an integrated design that combines the operating mechanism with the main body, allowing it to be installed as a fixed unit or, when equipped with a dedicated push‑type mechanism, to function as a withdrawable handcart unit.
