Technical features :
1.The operating mechanism and main circuit are in a top-and-bottom arrangement with a small handcart depth.
2.The screw propulsion mechanism with clutch could protect the operating mechanism from damage .
3.The newest "five-protection" interlocking design has no steel bracing wire in old model ZN85 so taht the endurance is reliable and longer.
4.The mechanical components are made of high quality steel alloy and through special surface treatment,the components could withstand the neutral salt spray test for more than 350 hours.
5.The cylindrical composite insulation main circuit features small volume,free of maintenance and few service.
