LW□-252 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker
CNKEEYA,LW□-252 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker is an outdoor product, applicable to 50Hz AC power grids with a maximum voltage of 252kV in areas with altitude ≤2000m, ambient temperature ≥-30℃ and pollution class ≤IV. It is mainly used for interrupting rated and fault currents, switching circuit lines and acting as an interconnection breaker, realizing efficient control and protection of power systems.
LW36-126 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker
LW36-126 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker linked spring operating mechanism, boasting a sleek design. It takes SF6 gas as insulation and arc-extinguishing medium, equipped with a pointer density relay for real-time gas monitoring.
LW36-126/T3150-40 High-Voltage AC SF₆ Tank-Type Circuit Breaker
CNKEEYA,LW36-126/T3150-40 High-Voltage AC SF₆ Tank-Type Circuit Breakerintegrates the circuit breaker and current transformer together, and the arc extinguishing chamber is horizontally installed in a grounded aluminum alloy shell, equipped with a CT26 type spring operating mechanism. It uses fewer components, has a simple and compact layout, and is overall sturdy and durable, meeting the requirements of oil-free switches. It has excellent mechanical characteristics and high reliability. All important components are processed by CNC and machining center equipment, and bearings are made of branded bearings (such as IKO, INA, SKF, etc.), with a mechanical life of up to 10000 times. Suitable for outdoor high-voltage switchgear with three-phase AC 50Hz, it can be used for control and protection of 72.5 (126) kV transmission and transformation systems; It can also be used for connecting circuit breakers and opening and closing capacitor banks.
ZCW□-72.5(126.5)/L Type Open-Type Switchgear Assembly
ZCW□-72.5(126.5)/L Type Open-Type Switchgear Assembly is a complete set of combination electrical apparatus that uses air as the external insulation SF6 gas as the arc extinguishing medium. The control and protection of 72.5KV transmission and distribution systems for three-phase AC can also be used for connecting circuit breakers and opening and closing capacitor banks. Suitable for urban substations, enterprise substations, and mountainous substations with tight land use.
LW□-12 Primary and Secondary Integrated SF₆ Circuit Breaker
LW□-12 Primary and Secondary Integrated SF₆ Circuit Breaker, which uses the magnetic field force received by the arc current to make the arc rotate at high speed along a certain section. Due to the relatively light weight of the arc, it gradually elongates and continuously contacts fresh SF6 gas during high-speed rotation, and is cooled and extinguished. This type of circuit breaker has the advantages of strong arc extinguishing ability, long electrical life, no current interruption when breaking small currents, and no overvoltage during operation. At the same time, it requires less operating power and has high reliability.
LN2-40.5 Indoor High-Voltage Sulfur Hexafluoride Circuit Breaker
LN2-40.5 Outdoor High-Voltage Sulfur Hexafluoride Circuit Breaker is an indoor device used in AC 50HZ three-phase systems. It can be used for protection and control in industrial and mining enterprises, power plants, and substations. And it can be used in frequent operating places. It can also be used as a contact circuit breaker and a capacitor bank circuit breaker.
