Product Description

Product DescriptionThis outdoor pole mounted vacuum circuit breaker serves as core switchgear for urban and rural overhead distribution networks. The whole unit adopts integrated stainless steel cabinet, equipped with three-phase integrated silicone rubber composite insulating bushings, built-in vacuum interrupter and spring stored energy operating mechanism. The equipment can be directly installed on distribution poles, realizing normal opening & closing of power lines, and rapidly cut off circuit under overload and short-circuit faults to achieve automatic grid protection. Silicone rubber insulating housing features excellent hydrophobic and anti-pollution performance, adapting to complex outdoor open-air working conditions. It is widely used in new rural power grid construction, urban distribution network renovation, photovoltaic and wind power supporting transmission lines, acting as key complete equipment for safe and stable operation of overhead distribution systems.Outdoor high-voltage automatic recloser device vacuum circuit breaker rated voltage 30KV, 33KV, 36KV and rated current 630A, 1250A, 1600A, three-phase AC 50/60Hz outdoor power distribution equipment. It is mainly used to break and close the power system load current, overload current and short circuit current. Environmental ConditionsAmbient temperature: – 40℃~+40℃Altitude: ≤2000mRelative humidity: ≤95% (daily average) or ≤90% (monthly average)Wind speed: ≤34m/s (equivalent to a pressure of 700pa on a cylindrical surface)Structure and FunctionProduct Advantages:Application Scenarios:- Anti-corrosion Stainless Steel Cabinet: Stainless steel housing resists rainwater, coastal salt fog and industrial acid corrosion, no rust after long-term outdoor service
- Anti-pollution Composite Insulating Bushing: Hydrophobic silicone sheds reduce pollution flashover risk, stable operation in heavy dust and humid areas
- Arc-free Vacuum Interruption: Arc extinguished inside vacuum chamber without open flame or waste gas, low component wear and long service life
- Stable Spring Stored Energy Mechanism: Fast response for opening and closing, low mechanical failure rate and easy maintenance
- Integrated Three-phase Compact Design: Small installation footprint, easy pole mounting with bracket by single worker
- All-weather Super Weather Resistance: Operate stably under high temperature, frost, heavy rain and thunderstorm all year round
- Multi-layer Safety Protection: Automatically break circuit under overload and short-circuit to avoid wire burnout and large-scale power outage
- Long Maintenance-free Operation: No easily worn consumables for core arc-extinguishing parts, no disassembly maintenance required under normal working conditionsAs supporting equipment for overhead power grid lines, it fits all kinds of medium voltage overhead distribution projects:
1.Section control and fault protection for main medium voltage overhead lines on urban & rural distribution poles
2.Switchgear for new rural power grid construction and old urban distribution network upgrading projects
3.Protection device for outgoing overhead transmission lines of photovoltaic and wind power stations
4.Outdoor power lines in coastal salt fog, mining dust and chemical industrial heavy corrosion zones
5.Supporting equipment for township industrial parks, agricultural irrigation dedicated lines and long-distance mountain distribution lines
It can be matched with pole mounting brackets, current transformers, zinc oxide lightning arresters and line fittings to build a complete outdoor power distribution automation system.
