Product Details
LW17A-126/T3150-31.5 Outdoor High-voltage Sulfur Hexafluoride Circuit Breaker LW17A-126/T3150-31.5 Outdoor High-voltage Sulfur Hexafluoride Circuit Breaker is designed based on the digestion and absorption of ABB's introduced technology. It uses sulfur hexafluoride gas as the main insulation and arc extinguishing medium and is equipped with a highly reliable spring operating mechanism. It is mainly used to complete the switching of normal load current, cut off fault current and convert power lines, and realize the control and protection of 126kV power system. The main technical parameters are as follows: l Rated voltage: 126kV l Rated current: 3150A l Rated short-time breaking current: 34.5kA (duration: 4s) l
Rated short-circuit closing current (peak): 80kA l Rated power frequency withstand voltage: 230kV l Rated lightning impulse withstand voltage: 550kV l Rated SF6 gas pressure (gauge pressure at 20℃) 0.5 MPa
