Product Description

This disengaging device adopts compact mechanical structure with simple outer dimension for convenient field mounting with standard M10 or M12 thread connection. It can effectively trigger separation under fault conditions to cut off the faulty arrester from the power circuit and avoid sustained short‑circuit risk for the grid. Three practical installation modes are available to fit bracket mounting, power station assembly and overhead line installation scenarios, paired with soft copper grounding wire or aluminum wire for reliable earthing connection. The whole unit features stable mechanical performance, easy assembly and maintenance‑free running, perfectly cooperating with different types of surge arresters in power distribution networks.
