High Voltage Pin Insulator

The High Voltage Pin Insulator 56-4 is an ANSI-standard model designed for high-voltage distribution applications. Its rated voltage is 46 kV. The structure height is 241 mm, and the disc diameter is 305 mm. The mechanical failing load is 13.3 kN. This product complies with ANSI C29.6. The creepage distance is 686 mm, while the dry arcing distance is 286 mm. The 46 kV rating is suitable for high-voltage distribution applications under the ANSI system. The product is used on 46 kV overhead lines and in substation bays around urban areas. The large disc diameter provides a long creepage path, which supports reliable operation at high voltage levels. We use a high-strength porcelain formula for the insulator body. Isostatic pressing provides a dense and uniform internal structure. This helps maintain stable electrical performance. The 13.3 kN mechanical failing load provides reliable mechanical support for high-voltage distribution applications.

Our company has more than forty years of experience in this field. We are familiar with the requirements for ANSI high-voltage products. For each batch of 56-4, we independently measure the creepage and dry arcing distances to verify compliance with ANSI requirements. High-voltage ANSI products have strict requirements for shed dimensions. We control these dimensions through high-precision molds and stable firing processes. Our annual production capacity reaches 26,000 tons, allowing us to handle large-volume orders. Our high-voltage testing center can perform power frequency withstand voltage tests and lightning impulse tests. We can also provide third-party test reports from SGS or TÜV. The product has been tested at the China Electric Power Research Institute and the XD Power Ceramics Institute. These testing records provide documented performance data for customer reference.

Normal delivery takes 30 to 40 days. Larger models require additional time for packing and container loading. We pack the products on reinforced wooden pallets and secure them with steel straps. This packaging provides reliable protection during long-distance sea transportation. The minimum order quantity is negotiable, and we also accept small trial orders. We support FOB, CIF, and DDP trade terms. Shipments can be arranged from Shanghai or Ningbo ports. The warranty period is 12 months. Manufacturing defects are replaced free of charge according to the agreed warranty terms. Our after-sales team responds within 24 hours and can assist with installation and product usage issues. This High Voltage Pin Insulator is designed for demanding high-voltage distribution applications.

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