Electrical Pin Insulator

The Electrical Pin Insulator PW-11-Y is designed for anti-pollution applications. Its rated voltage is 11 kV. The structure height is 170 mm, and the disc diameter is 170 mm. The mechanical failing load is 11 kN. It complies with BS 137 and IEC 60383. The "W" in the model number indicates the anti-pollution design, while the "Y" indicates a long-shank design. The creepage distance is 300 mm, and the dry arcing distance is 120 mm. This creepage distance is significantly longer than that of standard types at the same voltage level. This difference is particularly useful in areas with heavy pollution. We use a special anti-pollution porcelain formula. The body is available with semi-conducting glaze or high-gloss glaze. The surface resists dirt accumulation. This product is commonly used in coastal industrial zones and foggy, damp areas. It is installed on 11 kV distribution line tension sections and angle poles.

We have extensive experience in anti-pollution insulation solutions. Our technical center can adjust shed designs and glaze formulas according to different pollution levels. Our high-voltage laboratory can simulate damp heat and salt fog conditions for artificial pollution tests. For every batch of PW-11-Y, we measure the creepage and dry arcing distances to confirm that they match the specified drawings. If you have special pollution class requirements, we can prepare a suitable design plan and arrange type tests. The product has been tested at the China Electric Power Research Institute and the National Insulator Arrester Quality Supervision and Testing Center. Our R&D team can also assist with product selection. The team can use photos or pollution data from your installation site to provide recommendations. This approach helps us select a suitable Electrical Pin Insulator for different operating environments.

You can mix different models within the minimum order quantity. For export shipments, we use plywood cases or fumigated wooden boxes. We add separate partitions and cushioning materials inside the packages to protect the products during transportation. We respond to inquiries within 24 hours. For after-sales support, our technical staff can provide remote troubleshooting assistance during installation. Manufacturing defects are replaced free of charge within the warranty period. We support FOB and CIF trade terms. Shipments are available from Shenzhen or Ningbo. Normal delivery takes 25 to 35 days. For urgent orders, we can discuss expedited delivery options based on the production schedule. This Electrical Pin Insulator provides reliable performance for 11 kV distribution lines operating in challenging and polluted environments.

All products support custom dimensions, voltage ratings, OEM/ODM services, and manufacturing based on drawings.
