Pin Type Disc Insulator

The Pin Type Disc Insulator P-20-Y features a combined-disc design. Its rated voltage is 20 kV. The structure height is 152 mm, and the disc diameter is 152 mm. The mechanical failing load is 11 kN. This product complies with BS 137 and IEC 60383. The "Y" indicates long-shank mounting. The creepage distance reaches 298 mm, while the dry arcing distance is 133 mm. The combined-disc structure provides better pollution resistance than conventional shed types. The grooves between the skirts are deeper, which helps prevent dirt from forming a continuous conductive path along the surface. We use high-grade electrical porcelain for the ceramic body. We also control the glaze thickness evenly during production. This helps improve reliability in damp outdoor environments. This Pin Type Disc Insulator is mainly used on 20 kV overhead distribution lines and at substation bay entry points.

We manage every stage of production carefully. From ball milling to forming and drying, we keep records for each process. We use automated tunnel kilns for firing. The temperature difference inside the kiln is kept very small. This helps maintain consistent performance from batch to batch. Before shipment, we conduct power frequency breakdown tests and four-point bending load tests. We also have our own physical and chemical laboratory on site. The laboratory can test raw material content and the thermal stability of the ceramic body. Many of our long-term customers value our complete testing system because they can trace the quality of each production batch. If required, we also provide full inspection services. Your staff can witness the tests, or we can arrange a third-party inspection.

The minimum order quantity is flexible. You can mix different models in one order. Each model only needs to meet its minimum packing quantity. Our foreign trade team takes photos throughout the production and dispatch processes. We pack the products on export-standard wooden pallets with corner guards. The outer layer is wrapped with stretch film. This packaging protects the products from moisture and makes loading and unloading easier. The warranty period is 12 months after shipment. If any products are damaged during transit, you can send us photos and videos. We will arrange replacements or discuss appropriate compensation. We support multiple trade terms and shipping ports. This Pin Type Disc Insulator is suitable for utility distribution projects that require reliable outdoor insulation.

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