Usune is a professional high and low voltage electrical equipment manufacturer located in China, specializing in the research, development, production, and customization of high and low voltage circuit breakers, disconnect switches, grounding switches, and other equipment. The Outdoor Vacuum Circuit Breaker is the company's core outdoor power distribution product, specifically designed for complex and harsh outdoor operating environments.
This equipment is compatible with AC 50/60 Hz, 12 kV~35 kV power systems, employing harmless vacuum arc-extinguishing technology to achieve green and safe opening and closing operations. The fully sealed, weather-resistant structure can withstand rain, snow, wind, sand, dust erosion, and extreme temperature changes. As a key protection device for outdoor power grids, it is mainly used for power reception, distribution, control, and fault protection of outdoor lines, transformers, and other electrical equipment, ensuring the safe and stable operation of the power system. It is widely applicable to various outdoor power distribution scenarios such as urban and rural power grid upgrades; industrial and mining oil fields, highways and railways, and residential communities.
The core arc-extinguishing component of the Outdoor Vacuum Circuit Breaker, possessing excellent arc-extinguishing performance, capable of quickly and reliably interrupting load current and short-circuit current. No fire hazards, zero environmental pollution, and an exceptionally long electrical lifespan, effectively ensuring the safety and durability of equipment under frequent operation and fault protection conditions.
The cabinet is made of high-quality anti-corrosion steel plate or aluminum alloy, treated with multiple anti-rust, anti-aging, and waterproof sealing processes, achieving a protection rating of IP65 and above. It effectively resists rainwater penetration, dust accumulation, and wind and sand impact, adapting to extreme temperature changes in various regions and preventing equipment aging and failures caused by outdoor environmental corrosion.
Equipped with a mature manual and electric spring operating mechanism, featuring simple operating logic, stable performance, and fast opening and closing speeds. Supports on-site manual operation, centralized electric control, and remote automated operation. It can be integrated with intelligent power monitoring systems to achieve unattended intelligent operation of the equipment.
Utilizes high-performance composite insulation materials or high-strength porcelain insulators, offering high insulation strength and excellent anti-pollution flashover performance. It maintains stable insulation performance in harsh environments such as humid, saline-alkali, and heavily polluted conditions, eliminating insulation breakdown problems and ensuring the safe operation of the power system.
Designed specifically for extreme outdoor conditions, it integrates multiple properties including waterproofing, dustproofing, corrosion resistance, and anti-aging. It can operate stably in extreme temperature ranges from -40℃ to +85℃, perfectly adapting to harsh environments such as coastal saline-alkali areas, high-altitude low-pressure environments, and dusty industrial mining areas, demonstrating outstanding environmental tolerance.
Utilizing pure vacuum arc extinguishing technology, there is no arc splashing or harmful gas emission during operation, making it environmentally friendly. Core component losses are extremely low, with an electrical life of tens of thousands of cycles, meeting the demands of long-term, frequent operation of outdoor power grids.
Equipped with comprehensive mechanical interlocks and electrical fault protection functions, it effectively prevents misoperation and avoids equipment damage and personal injury accidents. The robust structure and high mechanical strength provide excellent dynamic and thermal stability, resisting short-circuit impacts and mechanical vibrations.
The compact structure and lightweight design significantly reduce on-site hoisting and installation difficulties, shortening the construction cycle. The core vacuum interrupter is maintenance-free, requiring minimal daily maintenance and effectively reducing the long-term maintenance costs of power projects.
Supports manual, electric, and remote operation modes. An optional intelligent monitoring system enables remote real-time monitoring of equipment operation status, data acquisition, and fault early warning, adapting to the needs of smart grid construction.
Compatible with various operating conditions such as outdoor ring network power supply, terminal power distribution, and transformer protection. It can be perfectly matched with outdoor switchgear, prefabricated substations, and other equipment, offering strong project adaptability and a wide range of applications.
This product is specifically designed for complex and harsh outdoor environments. It can operate stably in extreme temperature environments ranging from -40℃ to +85℃, adapting to various complex conditions such as high-altitude low-voltage, coastal saline-alkali, dusty industrial and mining environments, and desert windy conditions. With its IP65 high protection rating and anti-corrosion and anti-aging processes, it can effectively resist rain, snow, sandstorms, and dust erosion, demonstrating extremely strong environmental tolerance.
The core vacuum interrupter chamber allows for long-term maintenance-free operation, eliminating the need for frequent replacement and repair like traditional interrupter components. Routine maintenance only requires simple surface cleaning and checking the operating mechanism. Compared to traditional SF6 circuit breakers, it eliminates the cumbersome procedures of gas leak detection and gas replenishment, significantly reducing maintenance workload and overall costs, making it suitable for unattended operation of outdoor power distribution stations.
The product boasts excellent intelligent expandability. In addition to basic manual and electric operation, an intelligent monitoring module can be added to achieve remote real-time monitoring of equipment current, voltage, temperature, and fault status. It supports remote opening and closing, automatic fault alarms, and data uploading, and can seamlessly integrate with smart grid management systems, facilitating unattended and intelligent management of outdoor power distribution equipment.
