Product DescriptionFunctions and Features1. Utilizes predictive live-line touchable silicone rubber cable heads, fully sealed, fully insulated, maintenance-free, reliably ensuring personnel safety;
2. Compact structure with a sleek, aesthetically pleasing design; stainless steel double-layer enclosure ensures a service life exceeding twenty years;
3. Enables localized power outage maintenance without affecting main grid operations, minimizing outage scope;
4. Compatible with one or multiple SF6 load switches (vacuum circuit breakers). Flexible wiring configurations support up to eight branch circuits.
5. Optional surge arresters, short-circuit fault indicators, and current-limiting fuses available to meet diverse user requirements.
6. Widely applied in urban grid upgrades, residential communities, commercial centers, and other densely populated urban areas.Our company's 10kV high-voltage switchgear, renowned for its superior performance, standardized design, and aesthetically pleasing appearance, is widely deployed in major industrial parks, residential communities, densely populated urban areas, highways, railways, and various other locations. Available in single-door or triple-door configurations, its exterior can be fabricated from color-coated steel panels, eco-friendly landscape-grade materials, or stainless steel. It offers notable advantages including flexible modularity and comprehensive functionality. They can be configured as VS1 vacuum circuit breakers with SF6 ring main units, or entirely with SF6 ring main units. Capable of remote control, remote signaling, and remote measurement functions, the entire unit boasts an IP33 protection rating and excellent rain resistance.

· Power supply for dispersed residential areas in rural and suburban locations
· Urban road lighting systems
· Power supply along highways and railways
· Small load points such as communication base stations and surveillance equipment
· Remote industrial power usage in oil fields, mining areas, and similar locationsQuality Assurance
1. Manufactured in strict compliance with international and domestic standards such as GB1094 and IEC60076.
2. Each unit undergoes rigorous factory testing, including lightning impulse tests, temperature rise tests, and sudden short-circuit tests.
3. Provides a 3-year warranty and lifetime technical support.1. High Efficiency and Energy Savings: Utilizes premium cold-rolled silicon steel laminated cores paired with oxygen-free copper windings to significantly reduce no-load and load losses, enhancing energy utilization efficiency.
2. Fully Sealed Maintenance-Free Design: Features a corrugated oil tank with a fully sealed structure that completely isolates transformer oil from external air, effectively preventing oil aging and moisture ingress to achieve maintenance-free operation.3. Safe and Reliable: Incorporates a built-in pressure relief valve and a high-sensitivity gas relay, providing multiple layers of protection to ensure the safe operation of both the equipment and the power grid.4. Outdoor-Specific Design: The housing features a corrosion-resistant coating and is filled with high-quality transformer oil, offering superior waterproofing, dustproofing, and pollution flashover resistance. It operates reliably in extreme climates ranging from -40°C to +40°C.
5. Easy Installation: Equipped with dedicated mounting brackets on both sides, it can be directly secured to utility poles without requiring additional civil engineering foundations, significantly reducing construction time.
