Product Overview
The product chassis is made of stainless steel and hot-dip galvanized carbon steel with anti-ultraviolet protective coating to ensure the normal operation of the body in an outdoor environment. The parts are made of stainless steel to ensure the durability, stability and waterproof of the load switch. Anti-salt fog and other properties. The power is large, safe and reliable, long electrical life, frequent operation, less maintenance, obvious continuity and other outstanding features. The operation method adopts single lever manual operation, and also can adopt electric and remote control operation
