Line Post Pin Insulator

The Line Post Pin Insulator P-22-A is an Australian-standard line post model. Its rated voltage is 22 kV. The structure height is 165 mm, and the disc diameter is 230 mm. The mechanical failing load is 11 kN. This product complies with AS 1304. The "A" indicates a short-shank design. The creepage distance is 432 mm, and the dry arcing distance is 200 mm. The large disc diameter provides a longer creepage distance, which supports reliable outdoor operation. The line post design can withstand higher bending loads, making it suitable for line support and conductor fixing. We use high-quality electrical porcelain for the product body. High-pressure forming creates a dense structure and provides stable mechanical strength. This product is widely used on 22 kV overhead lines in Australia. It is also used in distribution projects in Southeast Asia.
