Product drawing
Industry Standard(s)
Applicable standards: IEC60168 & DL/T 627
All ferrous metal parts are hot dipgalvanized as per ISO1461
- The conductive switch blades, static contacts, and other components of the Disconnecting Switch are installed on these post insulators.
- Supporting weight: It must be able to withstand all mechanical loads caused by the switch body, conductive components, operating mechanism linkages, as well as icing, wind pressure, etc.
- Provide stability: It is the "skeleton" of the entire isolation switch structure, ensuring that the equipment remains stable during long-term operation and handling, without tilting or deformation.
- Ground insulation: It reliably isolates conductive parts with high potential (such as bus voltage, line voltage) from grounded metal structures (such as bases, brackets).
