Full Voltage Coverage from Distribution to Transmission
Our High Tension Circuit Breaker covers every voltage level from 10kV to 550kV. This broad coverage makes it suitable for distribution networks and ultra-high voltage transmission projects. We offer both vacuum and SF6 arc-quenching technologies. The vacuum version works best for medium-voltage applications. It has simple construction and requires no maintenance. The SF6 version handles high and ultra-high voltage scenarios. It offers large breaking capacity and excellent insulation performance. Our understanding of arc extinction and insulation technology spans all voltage levels. We have dedicated test stations for each voltage class. Our test methods match the specific needs of each product type. This comprehensive capability means you can source all your breaker needs from one supplier. You save time on procurement and vendor qualification. Your projects get consistent quality across all voltage levels.

Wide Selection of Current and Breaking Ratings
This High Tension Circuit Breaker gives you extensive rating options. Rated current ranges from 630A to 4000A. Short-circuit breaking current ranges from 20kA to 50kA. You can select the most economical rating based on your actual system short-circuit calculations. The module-based design approach improves our responsiveness. Different voltage products share common operating mechanisms and control systems. This commonality helps us deliver custom orders faster. We support on-demand customization for special requirements. These include special terminal shapes or secondary wiring configurations. The breaker can adapt to your specific installation needs. Spring operating mechanisms work well for medium and some high-voltage products. Hydraulic mechanisms are used mostly for ultra-high voltage products. They offer higher operating power and stable performance. Our breakers are built with the highest standards for safety and reliability.

Multiple Operating Mechanism Options
Our High Tension Circuit Breaker offers both spring and hydraulic operating mechanisms. Spring mechanisms are mature and reliable for most voltage classes. Hydraulic mechanisms provide stable performance for the most demanding applications. You can choose the option that suits your preferences and requirements. We understand that breakers serve as the last line of defense in power systems. This responsibility drives our commitment to quality. We select materials carefully for each component. We follow precise production and assembly procedures. Our testing ensures every breaker meets its design specifications. We support FOB trade terms for export orders. Professional packaging protects the breaker during shipping. Our 12-month warranty covers the product from delivery. We provide technical documentation to support installation and operation. Choose our High Tension Circuit Breaker for complete voltage coverage and dependable performance.
