H‑Energy
H‑Energy (part of the NEC Group) has launched production of the VGK‑110 sulfur hexafluoride (SF₆) column circuit breaker (110 kV). The equipment is designed for operation in the coldest regions: it can withstand temperatures as low as -60 °C and is ready for use in infrastructure projects in the Far North.
The new circuit breaker is rated for a nominal current of up to 3150 A and a breaking current of up to 40 kA. However, its key feature is its extended temperature range. There are currently few solutions on the 110 kV column circuit breaker market that can operate stably under conditions of extremely low temperatures.
Development of the device took 80 weeks. During this period, the company’s engineers designed an arc‑quenching chamber and a spring drive, and also developed special welding and assembly technologies. To manufacture the new product, a dedicated production tooling was designed and implemented.
Launching production of the VGK‑110 is part of the company’s long‑term strategy to expand its range of high‑voltage equipment. The technical solutions tested in this project will form the basis for H‑Energy’s new products: a tank circuit breaker and a hybrid cell at 110 kV. Thanks to the experience gained, it is planned to bring these products to market significantly faster.
