Key Features & Applications

  • The conductive switch blades, static contacts, and other components of the Disconnecting Switch are installed on these post insulators.
  • Supporting weight: Able to withstand all mechanical loads caused by the switch body, conductive components, operating mechanism linkages, icing, and wind pressure.
  • Structural Stability: Serves as the "skeleton" of the entire isolation switch structure, ensuring stability during long-term operation without tilting or deformation.
  • Ground Insulation: Reliably isolates conductive parts with high potential from grounded metal structures like bases and brackets.

Frequently Asked Questions

What are the primary standards for these post insulators?
These insulators comply with international and regional standards, specifically IEC60168 and DL/T 627, ensuring high quality and safety.
How is the corrosion resistance handled for metal parts?
All ferrous metal parts undergo a hot-dip galvanization process according to the ISO1461 standard, providing excellent durability in outdoor environments.
What is the creepage distance of this model?
The creepage distance is 1000mm, which is critical for preventing electrical leakage along the surface of the insulator.
Can these insulators withstand high mechanical stress?
Yes, they are designed with a cantilever strength of 2.3kN and a tensile strength of 27.5kN to handle switch body weight, wind, and icing loads.
What is the electrical withstand voltage rating?
The unit has a critical impulse withstand voltage (positive) of 230kV and a power frequency 1-minute withstand voltage (wet) of 95kV.
