The Usune Indoor High Voltage Breaker Switch is independently developed and manufactured by Zhejiang Usune Electric Co., Ltd., a professional high-voltage power transmission and distribution equipment manufacturer in China. As a core control and protection device for 10KV, 20KV, and 36KV power systems, it can be used in conjunction with power transformers and features stable breaking performance, high safety, low maintenance, and long service life. This product is manufactured in our factory according to strict industrial standards and is widely used in power transmission and distribution, industrial production, and new energy power generation.
The indoor high-voltage breaker switch uses an electromagnetic mechanism and arc-extinguishing system as its core. It relies on electromagnetic drive to complete the switching action, quickly interrupts fault current through a professional arc-extinguishing medium and structure, and achieves electrical isolation and voltage matching through a high-performance insulation system. Working with power transformers, it completes the step-up and step-down power supply, ensuring the stable and safe operation of the entire power system.

A 35KV photovoltaic power station in East China adopted the Usune 36KV Indoor high voltage breaker switch, equipped with a three-phase oil-immersed power transformer, to undertake the grid connection and circuit protection tasks of the photovoltaic units, effectively solving the problem of current fluctuation in new energy power generation. It operated without faulty tripping for two years, significantly reducing line losses and improving the overall power generation efficiency of the station.
A large urban data center uses Usune 10KV indoor high-voltage circuit breakers, along with indoor distribution transformers, to construct an independent high-voltage power distribution system. This provides comprehensive protection for the server power supply circuits, ensuring uninterrupted power supply to the data center 24/7 and preventing business losses due to power outages.
A1: It covers mainstream medium- and high-voltage specifications of 10KV, 20KV, and 36KV, perfectly matching power transformers of the same voltage level. Custom parameter adjustments are supported according to project requirements.
A2: It uses high-quality silicon steel sheets, copper windings, and high-strength insulation materials. With no rotating, easily damaged parts, its service life can reach over 20 years. Daily maintenance only requires periodic dust removal and contact condition checks; no complex maintenance is needed.
A3: Compatible with power transmission and distribution transformers, power distribution transformers, and generator transformers, it is widely used in indoor high-voltage power distribution scenarios such as substations, industrial parks, new energy power plants, residential communities, and data centers.
