LW36-72.5
The LW36-72.5 is a high-performance outdoor three-phase AC high-voltage SF6 circuit breaker developed for 72.5kV power transmission and distribution systems. Complying strictly with IEC 62271-100 and national GB standards, this professional high voltage switchgear is widely applied in large-scale power substations, thermal power plants, wind power bases, photovoltaic power stations and industrial heavy-duty power grid systems for circuit switching, overload protection and short-circuit fault isolation.
Adopting high-purity SF6 gas as the insulating and arc-extinguishing medium, the LW36-72.5 circuit breaker adopts advanced self-energy arc extinguishing technology. It delivers outstanding dielectric insulation performance and ultra-strong short-circuit breaking capability, ensuring rapid and stable arc extinction in extreme fault conditions. Compared with conventional high voltage breakers, this model features lower operating power, minimal mechanical impact and extremely low failure rate during long-term cyclic operation.
Equipped with a reliable high-strength spring operating mechanism, the LW36-72.5 outdoor circuit breaker achieves precise and consistent closing and opening actions. The overall fully sealed integrated structure is professionally treated with anti-corrosion, dust-proof and moisture-proof technology. It can adapt to harsh outdoor working environments, including high altitude, low temperature, coastal salt fog, heavy dust and strong wind, maintaining stable operation in all-weather conditions.
The LW36-72.5 SF6 circuit breaker supports multiple mainstream specifications of rated current and short-circuit breaking current to meet diverse requirements of national and international power engineering projects. With a compact and reasonable structural design, it is easy to install and debug on site, requiring almost no daily maintenance. It effectively reduces the operation and maintenance cost of power grid equipment and improves the overall operational efficiency of the power system.
As a core 72.5kV high voltage power device, the LW36-72.5 circuit breaker features high safety coefficient, stable mechanical performance and ultra-long service life. We provide global customers with factory direct sales, customizable technical solutions, complete product certification and professional after-sales support, ensuring reliable and safe operation of various high-voltage power projects.
