Disc Pin Insulator

The Disc Pin Insulator P-33-Y is a large-diameter model designed for 33 kV applications. It has a structure height of 244 mm and a disc diameter of 280 mm. The mechanical failing load is 13 kN. It meets BS 137 and IEC 60383 standards. The "Y" indicates a long-shank design. The creepage distance is 630 mm, while the dry arcing distance is 360 mm. The large disc diameter provides a longer creepage path, which helps reduce the risk of flashover in polluted areas. We have refined our porcelain formula several times. The current formula provides better anti-aging performance than our earlier versions. We offer both brown and white glaze options. Both surfaces are smooth and resist dirt accumulation. This helps extend the maintenance interval. This Disc Pin Insulator is commonly used on 33 kV overhead lines, section switches, and the high-voltage sides of pole-mounted transformers.

Large products require more precise firing control. We have two eco-friendly shuttle kilns and one tunnel kiln. Our annual production capacity reaches 26,000 tons. For large pieces, we use PLC-based automatic temperature control. We strictly follow the specified firing curve throughout the process. Our quality team has 16 members, and they focus on shed uniformity and wall thickness for large products. Before shipment, we conduct 100% visual inspections and spot checks of electrical performance. We hold ISO 9001 certification, and our quality control records cover the entire production process from start to finish. You can request factory test reports for each batch. We also accept OEM customization, including surface markings, packing marks, and brand logos.

Custom sample development takes 20 to 30 days. Normal order delivery takes 30 to 40 days because large products require longer drying and firing times. Third-party factory inspections are welcome. We have previously hosted TÜV and Intertek inspections. Our standard payment terms are 50% deposit and 50% before shipment, although the ratio is negotiable. We pack the products in fumigated solid wood pallets. Each unit is separated with protective partitions. The packaging is suitable for both sea and land transportation. For this Disc Pin Insulator, we suggest placing orders early to secure your production and delivery schedule. We also provide export documents and quality data to support smooth customs clearance.

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