LW8-40.5 Outdoor High Voltage SF6 Circuit Breaker | 35kV Porcelain Column Sulfur Hexafluoride Breaker
The LW8-40.5 Outdoor AC High-Voltage SF6 Circuit Breaker is a three-phase electrical appliance designed for power systems with a rated voltage of 35kV/40.5kV and a frequency of 50Hz. Utilizing sulfur hexafluoride (SF6) gas as both the arc-extinguishing and insulation medium, it employs a compressed gas arc-extinguishing structure to ensure strong breaking capacity. This durable breaker is ideal for transformer substations and power plants to open or close rated and short-circuit currents. It can also function as a connecting circuit breaker or capacitor bank switch, featuring an integrated current transformer for precise measurement and protection.
