Product Description

Excellent Performance:
1. New product, new craft; More exquisite, cuter, refined appearance like a pagoda;
2. Compared to the products in current marketing, our products have reduced the height and width of nearly 70mm which saves the space inside the transformer. It is a preferred product of oil-saving and material-saving.
3. Though outer electric-charged limit reduced, there is a slight increase in insulation and the crack edge's voltage withstand is more reliable.
4. Change the originally assembled three single-pieces of switch insulation frame into a trinity mold. The formidable tonnage will be suppressed into overall support, thus forms a better material density, greater mechanical strength, and a higher level of pressure withstand.
5. Remove the metal screw of the three single compartment bracket connecting will also remove the adverse factors caused by the discharge of potential suspensions.
6. Use inter-clamp moving contact of special structure will make muti-contact between moving contacts and fixed contacts. Which enables smaller contact resistant.
