Gas Insulated Vacuum Circuit Breaker

Kechang's Gas Insulated Vacuum Circuit Breaker (GIS VCB) adopts Class H (180°C) insulation system, with windings wrapped in Nomex paper and epoxy resin casting for enhanced insulation performance. The epoxy resin used is of flame-retardant F1 grade, ensuring long-term heat resistance and reducing insulation aging risks even in high-temperature environments. This design solves the problem of frequent insulation breakdown in traditional circuit breakers, extending the product's service life to over 25 years. We provide detailed insulation test reports to verify performance, helping you avoid potential safety hazards in power distribution systems.

Fire safety is non-negotiable for projects in hospitals, data centers and commercial buildings. Our GIS VCB features an oil-free and leak-proof structure, eliminating the risk of oil leakage and fire caused by traditional oil-immersed circuit breakers. It has passed IEC 60076 and UL fire safety tests, with low ignition risk and strong flame retardancy. This product solves the fire safety concerns of procurement in high-demand scenarios, ensuring compliance with local safety regulations. The gas-insulated design also prevents external dust and moisture from entering, further enhancing fire safety and operational stability.

Noise pollution is a key concern for circuit breakers installed in urban areas and residential communities. Kechang optimizes the GIS VCB's structure with improved iron core lamination, low-noise fans and shock-absorbing components, ensuring noise levels range from 45-55 dB (depending on specifications), which fully complies with IEC and GB standards. The low-noise design solves the problem of disturbing residents or staff in nearby areas, making the product suitable for indoor and outdoor installations in noise-sensitive environments. Unlike ordinary circuit breakers with harsh operating noise, our product balances performance and quiet operation, reducing complaints and maintenance due to noise issues.

Efficient maintenance management is a core demand for procurement teams. Our GIS VCB is equipped with PT100 temperature sensors and intelligent thermostats, which can real-time display temperature, automatically control fan start/stop and trigger over-temperature alarms. It supports MODBUS/RS485 remote monitoring protocol, allowing you to check operational status, collect data and handle faults remotely without on-site inspections. This smart monitoring system solves the problem of high labor costs and low efficiency in traditional manual maintenance, minimizing downtime and ensuring continuous power supply. The system is easy to integrate with existing power monitoring platforms, reducing integration costs for your projects.

Circuit breakers need to withstand harsh outdoor and complex environmental conditions. Kechang's GIS VCB offers protection levels of IP30, IP44 and above, with excellent dustproof, moistureproof and corrosion-resistant performance. It can operate stably in the temperature range of -25°C to 40°C, adapting to high-altitude, high-humidity and coastal areas with strong corrosive air. This product solves the problem of poor environmental adaptability of ordinary circuit breakers, avoiding faults caused by extreme weather or harsh environments. The compact gas-insulated structure also reduces space occupation, making it suitable for projects with limited installation area.

We understand that different projects have unique requirements for circuit breakers. Kechang provides professional customization services, including voltage levels, rated capacity (50kVA-2000kVA), protection grades, installation sizes and wiring methods (copper bar/cable terminal). This solves the problem of mismatching between standard products and project needs, ensuring the product perfectly fits your power distribution system. All GIS VCB products comply with IEC 60076, IEEE C57, CE, UL and RoHS standards, meeting EU EcoDesign energy efficiency regulations. We offer a 3-year quality guarantee and complete certification documents, ensuring product reliability and after-sales support. As an ISO 9001 and ISO 14001 certified enterprise, Kechang strictly controls production processes to deliver high-quality products for your procurement projects.
