Product Description
Overview:
The FLN36 SF6 gas-insulated load break switch is a dual-break rotary switch that utilizes sulfur hexafluoride gas as the insulating and arc-extinguishing medium, designed for 7.2-24kV XGN15-12 RMU distribution systems. Each load break switch is filled with SF6 gas at a pressure of 0.4 bar, with the gas permanently sealed inside.
Advantages:
- Safety: Manufactured to the highest IEC standards, featuring a non-corrosive, leak-proof enclosure, inspection windows, built-in voltage indicator, interlocking mechanism, gas pressure gauge, and more.
- Cost-efficiency: A lifespan of at least 30 years, maintenance-free due to its sealed-for-life design, and low operating costs.
- Reliability: Each unit undergoes rigorous testing, equipped with a highly durable and reliable actuator, proven in global applications.
- Intelligent integration: Modular design, compact form, easy to install, and versatile, suitable for a wide range of applications with a single switch.
