LW17A-126/T3150-31.5 Outdoor high-voltage sulfur hexafluoride circuit breakerDetailed product description：

The LW17A-126/T3150-31.5 outdoor high-voltage sulfur hexafluoride circuit breaker is designed based on the technology introduced by ABB, using sulfur hexafluoride gas as the main insulation and arc extinguishing medium, and equipped with a highly reliable spring operating mechanism. It is mainly used to complete operations such as switching normal load current, cutting off fault current, and converting power lines, achieving control and protection of the 126kV power system.

The main technical parameters are as follows:

Rated voltage: 126kV
Rated current: 3150A
Rated short-time breaking current: 34.5kA (duration: 4s)
Rated short-circuit closing current (peak): 80kA
Rated power frequency withstand voltage: 230kV
Rated lightning impulse withstand voltage: 550kV
Rated SF6 gas pressure (gauge pressure at 20 ℃) 0.5 MPa
