As a professional manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our robust and reliable 35kV/10kV Outdoor Vacuum Circuit Breaker. Engineered for the most demanding environments, this circuit breaker is specifically designed to provide safe, efficient, and uninterrupted power distribution in mining operations and heavy industrial facilities. Our commitment to quality, backed by ISO9001 certification, ensures that every unit delivers exceptional performance and longevity, protecting your critical electrical infrastructure from faults and overloads. We understand the unique challenges of industrial power management, which is why we offer customizable solutions to perfectly match your specific application requirements.
This outdoor vacuum circuit breaker represents a significant advancement in medium-voltage protection technology. Its core component is a high-performance vacuum interrupter, which provides superior arc quenching capabilities in a compact, maintenance-free design. Unlike traditional oil or SF6 circuit breakers, the vacuum technology eliminates the risk of fire, eliminates the need for gas handling, and significantly reduces environmental concerns. The breaker is housed in a rugged, weatherproof enclosure designed to withstand harsh outdoor conditions, including extreme temperatures, humidity, dust, and corrosive atmospheres commonly found in mining and industrial sites.
Key Features and Technical Advantages:
- Superior Interruption Performance: The vacuum interrupter ensures fast and reliable interruption of fault currents, minimizing damage to downstream equipment and reducing system downtime.
- Minimal Maintenance: Sealed-for-life vacuum interrupters and a simple spring-operated mechanism drastically reduce the need for routine maintenance compared to air-blast or oil circuit breakers.
- Enhanced Safety: No flammable oil or greenhouse gases (SF6) are used, making it a safer choice for personnel and the environment. The design includes clear isolation and earthing points.
- Robust Construction: The enclosure is typically constructed from galvanized steel or corrosion-resistant coated materials, providing excellent protection against weather and industrial pollutants.
- Flexible Configuration: We offer a high degree of customization. Options may include different current and short-circuit ratings, control voltage options (AC/DC), communication interfaces for remote monitoring (optional), and specific mounting arrangements to fit existing structures.
- Long Electrical Life: Vacuum interrupters are capable of a high number of mechanical and electrical operations, ensuring a long service life even in frequently switched applications.
The benefits for your operation are substantial. By integrating this circuit breaker into your power distribution network, you gain improved system reliability, leading to fewer production stoppages. The reduced maintenance requirements translate into lower long-term operating costs and less need for specialized maintenance crews on-site. Furthermore, the enhanced safety profile protects your workforce and helps you meet stringent environmental and safety regulations common in the mining and heavy industry sectors.

Frequently Asked Questions (FAQ)
-
What are the main advantages of a vacuum circuit breaker over an SF6 type for outdoor use?
Vacuum circuit breakers offer several benefits: they are more environmentally friendly as they contain no greenhouse gases, require less maintenance, have a compact design, and are not affected by low temperatures which can liquefy SF6 gas. -
How customizable is this circuit breaker for my specific mining application?
We offer a high degree of customization. You can specify the rated voltage (e.g., 10kV, 35kV), current rating, short-circuit breaking capacity, control voltage, presence of current transformers, and mounting structure details to integrate with your existing switchgear or poles. -
What is the expected maintenance interval for this outdoor vacuum circuit breaker?
Thanks to the sealed vacuum interrupter and robust mechanism, routine maintenance is minimal. Primary tasks involve periodic visual inspection, mechanical operation checks, and cleaning of external insulation. Detailed maintenance schedules are provided in the manual. -
Can this breaker be integrated with remote monitoring and control systems (SCADA)?
Yes, this is an available option. The breaker can be equipped with motorized charging, auxiliary switches, and provisions for communication modules (like IEC 61850 or DNP3) to enable integration into modern supervisory control and data acquisition systems. -
What standards does this product comply with?
The breaker is designed and tested in accordance with international standards such as IEC 62271-100 for circuit breakers and IEC 62271-1 for common specifications. Specific standard compliance can be confirmed based on your regional requirements. -
What is the typical delivery lead time for a customized order?
Lead time depends on the complexity of the customization and current production schedule. Standard configurations may have shorter lead times, while fully customized units require more engineering and manufacturing time. We provide estimated timelines upon receipt of your detailed specifications. -
How does the breaker perform in extremely dusty or corrosive environments common in mining?
The enclosure is designed to be weatherproof and resistant to ingress of dust and moisture (typically IP54 or higher). For highly corrosive atmospheres, we can recommend or apply special protective coatings on the enclosure to enhance corrosion resistance. -
Do you provide technical support and spare parts?
Yes, as the manufacturer, we provide comprehensive technical documentation, installation guidance, and a reliable supply of genuine spare parts, including vacuum interrupters and mechanism components, to ensure the long-term operation of your equipment.
