Introducing our state-of-the-art Outdoor Sulfur Hexafluoride (SF6) Dead Tank Circuit Breakers, designed to deliver unparalleled reliability and performance in high-voltage power systems. Engineered with advanced technology, these circuit breakers are tailored for outdoor applications, ensuring efficient fault isolation and system protection under various environmental conditions. Rated at 72.5 kV, they cater to both 1200 A and 1250 A continuous currents, making them suitable for a wide range of industrial and utility applications.
Equipped with three SF6 interrupters, these breakers boast an impressive interrupting current rating of 31.5 kA, guaranteeing rapid fault clearing even under extreme conditions. The inclusion of six 150:5 ratio CTs enhances relay accuracy, while the trip-free spring operation mechanism ensures swift response to faults without delay. The anti-condensation cabinet heater maintains internal components in optimal condition, regardless of external weather, further enhancing longevity and reliability.
Our design incorporates a comprehensive control package featuring 12-stage auxiliary contacts, a 110VDC trip coil, dual voltage options for closing coils (48 VDC / 110VDC), and an auxiliary voltage supply of 110/220 VDC. The user-friendly interface includes a mechanical position indicator, an operation handle, isolating switches, and conveniently located terminal blocks for easy wiring. Safety is prioritized with hot-dipped galvanized mounting structures, ensuring corrosion resistance and durability over time.
To support maintenance and operational efficiency, each unit comes complete with a gas charging device featuring a regulator valve, a gas leak detector, and a reserve supply of SF6 gas. Compliance with EN 62271-1, EN 62271-100, EN 60273, and other relevant EN (IEC) standards assures customers of the highest quality and adherence to international safety regulations.
