LW8-40.5

LW8-40.5

The LW8-40.5 is a high-performance outdoor SF6 circuit breaker developed for 35kV/40.5kV three-phase AC power distribution systems. Adopting sulfur hexafluoride gas as insulation and arc extinguishing medium, this breaker delivers excellent dielectric strength and reliable short-circuit breaking performance, ensuring safe and stable operation of power transmission lines and substation equipment.
Equipped with a high-precision spring operating mechanism, the LW8-40.5 SF6 circuit breaker features flexible opening and closing action, low mechanical failure rate and no frequent maintenance. The fully sealed integral gas chamber structure effectively reduces gas leakage, with an ultra-low annual leakage rate, adapting to long-term outdoor operation in complex environments such as high temperature, severe cold, humidity and dust.
This model supports multiple rated current and breaking capacity specifications, covering 630A, 1250A, 1600A and 2000A, fully complying with IEC and international industry standards. It is widely applicable in power grid reconstruction, industrial and mining enterprises, photovoltaic power stations, wind power plants and urban outdoor substations, undertaking circuit switching, overload protection and short-circuit fault protection functions.
With the advantages of compact structure, stable performance, long service life and low operation cost, the LW8-40.5 outdoor SF6 circuit breaker has become a mainstream and reliable high-voltage switch device for medium and high voltage outdoor power systems.
