We are proud to introduce our Customizable HV Circuit Breaker for 10kV and 35kV applications, engineered to deliver superior protection and control in demanding power distribution networks. This product is designed with flexibility at its core, allowing us to tailor specifications to meet your unique project requirements, ensuring seamless integration and optimal performance. Backed by our extensive experience and a dedicated technical support team, we offer not just a product but a comprehensive partnership, complete with detailed installation guides to facilitate smooth deployment and long-term operational success. Our commitment to quality and customer-centric approach makes this circuit breaker a smart investment for enhancing grid stability and safety.
This high-voltage circuit breaker is a critical component for isolating and protecting electrical circuits from damage caused by overloads or short circuits. Its robust design and advanced technology ensure reliable operation under various environmental and load conditions.
- Tailored Configuration: We understand that every power system has unique demands. Our breakers are highly customizable in terms of rated current, breaking capacity, control voltage, and auxiliary contacts. Whether you need a specific communication protocol interface or special mechanical interlocks, our engineering team can develop a solution that fits your exact blueprint.
- Advanced Interruption Technology: Utilizing either SF6 or vacuum as the insulation and arc-quenching medium, our breakers ensure fast and effective current interruption. This technology minimizes maintenance needs, enhances safety by containing the arc within a sealed chamber, and provides a long electrical life, reducing the total cost of ownership.
- Robust Mechanical Design: Featuring a reliable spring-operated mechanism, the breaker ensures quick and consistent opening and closing operations. The mechanism is designed for durability, capable of withstanding thousands of mechanical operations with minimal wear, which is crucial for frequent switching applications.
- Enhanced Safety Features: Safety is paramount. Our circuit breakers incorporate multiple protective features, including clear ON/OFF indicators, earthing switches (optional), and secure mechanical and electrical interlocks to prevent incorrect operation, protecting both personnel and equipment.
- Comprehensive Monitoring: Optional smart monitoring modules can be integrated to provide real-time data on parameters like contact wear, spring-charging status, and operation counts. This facilitates predictive maintenance, helping to prevent unplanned outages and extend equipment lifespan.

Frequently Asked Questions (FAQ)
Q1: What level of customization is available for these HV circuit breakers?
A1: We offer extensive customization options. You can specify parameters such as the rated current, breaking capacity, control voltage (DC or AC), auxiliary contact configurations, communication interfaces (e.g., Modbus), and the inclusion of specific accessories like earthing switches or smart monitoring devices. Our engineering team works with you to finalize the specifications.
Q2: What is the lead time for a customized order?
A2: The lead time depends on the complexity of the customization. For standard configurations with minor modifications, it typically ranges from 4 to 6 weeks. For fully customized designs requiring new tooling or extensive testing, the timeline will be discussed and confirmed during the order quotation process to ensure transparency.
Q3: Do you provide installation and commissioning services on-site?
A3: While we provide comprehensive, step-by-step installation guides, drawings, and manuals with every shipment, we primarily offer remote technical support for installation and commissioning. For complex projects, on-site service can be arranged and quoted separately based on the location and scope of work.
Q4: What are the main differences between SF6 and Vacuum interruption technology in your breakers?
A4: SF6 breakers use sulfur hexafluoride gas for insulation and arc quenching, offering high breaking capacity and compact design. Vacuum breakers interrupt the arc in a vacuum chamber, known for their long contact life, minimal maintenance, and environmental friendliness as they do not use greenhouse gas. The choice depends on your specific application requirements, which we can help you evaluate.
Q5: Are spare parts readily available for your circuit breakers?
A5: Yes. As the manufacturer, we maintain an inventory of critical spare parts such as contacts, coils, springs, and control modules. We can supply spare parts kits with the initial order or as needed throughout the product's lifecycle to ensure minimal downtime for maintenance.
Q6: What standards do your 10kV and 35kV circuit breakers comply with?
A6: Our products are designed and tested in accordance with major international standards, primarily IEC 62271-100 for high-voltage alternating current circuit breakers. They also conform to relevant national standards like GB 1984. Specific standard compliance can be detailed in the product test reports provided with the shipment.
Q7: Can your breakers be integrated into existing switchgear from other brands?
A7: Integration depends on the mechanical dimensions, electrical interfaces, and control protocols of the existing switchgear. We offer customization of mounting dimensions and interface panels. We recommend providing the detailed specifications or drawings of your current switchgear for our engineers to assess compatibility and propose a feasible integration solution.
Q8: What kind of technical support do you offer after the sale?
A8: Our post-sales support includes assistance with installation queries via email or video call, troubleshooting guidance, and providing documentation updates. We also offer training materials for your operations and maintenance teams. For critical issues, our engineers are available for dedicated remote support sessions.
