As a well-known premium brand with a long history in the electrical equipment industry, Youbian focuses on researching, manufacturing and selling various types of Vacuum Circuit Breakers. With solid manufacturing capabilities and mature engineering support experience, it provides global power engineering customers with switchgear solutions that are highly stable and safe.
A Vacuum Circuit Breaker is a crucial protective switch device in high and low voltage power distribution systems. It achieves circuit opening and closing as well as fault isolation through a vacuum interrupter chamber. It features no oil pollution, low noise, high safety, and long service life. It is the mainstream switch equipment for modern power transmission and distribution, industrial power distribution, and project renovations.
Compared to traditional circuit breakers, the Vacuum Circuit Breaker has stable arc-extinguishing performance and a long maintenance-free period. It can be adapted for high-frequency opening and closing operations, effectively ensuring the safe and stable operation of the entire power system.
As a professional Manufacturer, Youbian relies on its own production base and mature manufacturing system. As a reliable China-based electrical equipment Supplier, it focuses on providing high-quality vacuum circuit breaker complete sets and supporting equipment to domestic and foreign customers, meeting the needs of various engineering procurement and export requirements.
Our main product line of vacuum circuit breakers is divided into two series: indoor and outdoor. It covers all scenarios of high and low voltage power distribution projects and can meet the usage requirements of different installation environments, voltage levels, and construction standards:
The indoor vacuum circuit breaker is a dedicated equipment with an embedded cabinet structure. It is compact in design, small in size, and flexible in operation, without any risk of fire or explosion. It is suitable for closed power distribution scenarios. The product has excellent insulation performance and fast opening and closing speeds. It can precisely cut off circuit faults such as short circuits and overloads. It is mainly used in conjunction with high-voltage switch cabinets, distribution rooms, factory power distribution rooms, office buildings, and factory automation power distribution systems. It is suitable for long-term stable indoor operation and is the preferred equipment for urban industrial and commercial power distribution and indoor complete electrical projects.
The outdoor vacuum circuit breaker adopts an integrated sealed protection structure, featuring waterproof, dustproof, corrosion-resistant, anti-aging, and resistance to high and low temperatures. It can adapt to complex and harsh working conditions in the field. The equipment does not require a cabinet for protection and can be directly installed outdoors. It is widely used in outdoor substations, urban and rural power grid renovations, rail transit, outdoor power distribution in mines, and outdoor transmission lines, etc. It has strong anti-environment interference capabilities and can operate stably in harsh weather conditions such as rain, snow, and sandstorms, meeting the long-term outdoor power operation requirements.
A1: No, they cannot. The indoor model has no outdoor protection structure and is only suitable for enclosed dust-free indoor environments; the outdoor model has a high-strength protection level and is specifically designed for harsh outdoor conditions. Mixing them will cause equipment failure.
A2: The equipment uses vacuum arc extinguishing, which is pollution-free, requires no frequent maintenance, has strong breaking capacity, operates stably, and has a much longer service life than traditional switchgear, significantly reducing operation and maintenance costs.
A3: Yes, we can customize products according to voltage levels, installation dimensions, and control parameters. We can undertake various engineering support, foreign trade batch orders, and bidding project cooperation.
A4: Factory warranty guarantee, providing long-term technical consultation, fault diagnosis and maintenance guidance, to solve all the problems related to the use and operation of the customer's equipment throughout the process.
