post insulators

post insulator for power grid

Changsha Rich’s post insulators provide essential support and insulation for busbars, disconnect switches, and other live components in substations and switchgear. Engineered for high mechanical load-bearing capacity and outstanding electrical insulation, our post insulators ensure the structural integrity and safety of your electrical installations, even in demanding environments.

Key Features of Our Post Insulators:

  • Exceptional Load Capacity: Designed to support significant static and dynamic loads.
  • Creepage Distance Optimization: Designed for polluted areas to prevent flashovers.
  • Anti-Flashing Design: Ensures stable performance in wet conditions.
  • Easy Installation: Standardized mounting holes and designs for quick integration.
  • Available in Porcelain and Composite Materials: Choose the best material for your application.

Applications:

  • Substation Busbar Support
  • Disconnect Switches
  • Railway Electrification Systems

post insulator

Our post insulators offer cantilever strength up to 16kN and compressive strength exceeding 100kN, designed to withstand high mechanical loads in substations.
End fittings are typically hot-dip galvanized cast iron or ductile iron, attached with high-strength Portland cement for superior mechanical integrity.
Yes, we have a specific range of post insulators designed with high dynamic strength and flexibility to meet stringent seismic requirements.
Yes, we can supply complete units with all necessary mounting hardware (bolts, washers, nuts) pre-assembled or kitted for easy and fast installation.
Each insulator is individually separated by foam or cardboard in a robust wooden crate, ensuring zero damage during transit. We have a proven track record of a breakage rate below 0.02%.
