The Cage Type Explosion-Proof Insulated Tube for Arrester is a specially designed insulation shell component used for surge protection devices in high-voltage systems. Made from high-strength epoxy and fiberglass composite materials, this tube delivers excellent insulation, mechanical durability, and explosion resistance.
Its cage-type design enhances safety during internal fault conditions by preventing external explosion impact, making it ideal for power distribution, rail transit, and renewable energy protection systems.
