Arc-extinguishing Tube for Fuses

The polymer melting tube is the core load-carrying and arc-extinguishing component of the outdoor jet-type drop-out fuse. It replaces the traditional steel paper tube and phenolic paper tube. It is matched with the RW/PRW series 10kV and 35kV outdoor drop-out fuses and is used in power distribution lines and the high-voltage side of power distribution transformers to achieve overload and short-circuit protection. It complies with the GB/T 15166.3 and DL/T 640 standards. Applicable scenarios
General suburban routes, coastal salt-spray areas, chemical pollution areas, mountainous regions with high ultraviolet radiation, and humid and rainy areas.

Performance advantage
