Note: Made of stainless steel, other sizes can be customized according to customer requirements!
Usage steps:
1. Determine the effective value or DC value of the working voltage;
2. Determine the material group (based on the comparative tracking index, it is divided into: Group I material, Group II material, Group IIIa material, Group IIIb material.)
3. Determine the pollution level; determine the insulation type (functional insulation, basic insulation, additional insulation, reinforced insulation).
