Summary
LW3-12 outdoor high-voltage sulfur hexafluoride circuit breaker (SF6 circuit breaker) is a high-voltage circuit breaker used outdoors using sulfur hexafluoride (SF6) gas insulation and arc extinguishing medium with excellent insulation and arc extinguishing performance. This product is manufactured by Shaanxi Taikai Electrical Equipment Co., Ltd. It is suitable for urban power network with concentrated load, tight land use and mountain power stations with steep terrain, difficult construction and inconvenient maintenance. It can also be used in special places such as high altitude and pollution. SF6 circuit breaker has a series of outstanding advantages, such as small size, safe operation, high reliability, easy installation, long electrical life, low noise, long non-maintenance operation cycle and less maintenance workload. It will replace the oil circuit breaker on the column.
LW3-12 series sulfur hexafluoride circuit breaker is a kind of on-column circuit breaker with SF6 gas as arc extinguishing and insulation medium. It is a replacement product for urban and rural power networks. Its excellent performance-price ratio is incomparable with other 12KV class outdoor circuit breakers. LW3-12 series sulfur hexafluoride circuit breakers are developed in accordance with GB1984-89 AC high voltage circuit breakers.
