Multi-Shed Porcelain Line Post Insulator

The PS series uses a multi-shed external-insulation profile for outdoor overhead lines requiring conductor support and insulation.
Additional sheds extend the surface creepage path and are intended for outdoor conditions involving rain, moisture, or contamination.
The Multi-Shed Porcelain Line Post Insulator is a project option when a longer creepage configuration is needed than the installation would otherwise provide.

Selecting by Height and Load
 

Minimum nominal creepage distance across the series is approximately 300–1450 mm.

Structural height ranges approximately 224–660 mm, giving buyers a basis for checking installation space and insulation distance.

Rated cantilever failing load is 12.5 kN, while lightning impulse withstand is approximately 105–325 kV.

Selection should consider structural height, creepage distance, mechanical grade, and the project's insulation requirement together.

Drawing and Sample Alignment

 

OEM/ODM production can follow customer technical drawings or a product prototype.

For PS-series sourcing, project discussions can focus on required structural height, creepage distance, and mechanical grade.

Sample confirmation is supported before mass production when the buyer needs to verify project fit.

Column-Type Inspection Points

 

Production includes raw-material treatment, forming, clay preparation, glazing, firing, and inspection of porcelain insulating parts.

Inspection resources cover bending performance, dimensions, creepage distance, and electrical performance.

Finished products are fully inspected before packing, and third-party inspection is accepted.

Production Visibility

 

Export packaging is arranged according to the receiving requirements of the buyer's destination country.

Standard specifications generally require 30 days for production and customized versions generally require 45 days.

Photo or video progress updates can be supplied during order execution.

Buyers sourcing the Multi-Shed Porcelain Line Post Insulator can use the confirmed dimensions and creepage range as the starting point for technical comparison before requesting a sample.

Because the PS series covers a broad dimensional range, the exact sub-model should be confirmed before quotation and production scheduling.
