LW36-126 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker

 Structural characteristics

  LW36-126 Outdoor High-Voltage AC Sulfur Hexafluoride (SF₆) Circuit Breaker, with a spring operated mechanism for the three phases arranged in the center and linked by the three phases, resulting in a novel and exquisite appearance. The circuit breaker uses SF6 gas as the insulation and arc extinguishing medium. During operation, the three poles of the circuit breaker are connected to SF6 gas, and a pointer type density relay is used to monitor its pressure and density. Due to the use of self powered arc extinguishing principle and optimized design in the circuit breaker motion system, the mechanical efficiency has been effectively improved and the operating power has been greatly reduced; Excellent breaking performance and long electrical lifespan;

 The installation chassis and support are made of steel plates that are bent as a whole, and the surface treatment is all hot-dip galvanized. All exposed fasteners are made of high-strength materials and hot-dip galvanized, or use stainless steel standard parts. The outer shell of the mechanism box is made of stainless steel material, so the product has excellent corrosion resistance;

 High mechanical reliability, capable of frequent operation;

 Due to the inherent high insulation strength of sulfur hexafluoride gas and the use of superior contact movement in circuit breakers, there is no reignition of the breaking capacitive current; The external insulation level is high, and the external insulation is designed with a large creepage distance. The creepage distance is ≥ 31mm/kV, and the anti pollution performance is excellent. Can operate safely even in harsh environments; Strong current carrying capacity: Conduct a temperature rise test at 1.2 times the rated current of 3150A, which is 3780A, and there is still a large margin of temperature rise at each point;

 The overall appearance structure of the product is compact, easy to install and debug on site, and the maintenance workload is small.
