Medium Voltage Pin Insulator

The Medium Voltage Pin Insulator 55-5 is an ANSI-standard pin-post model designed for medium-voltage distribution. Its rated voltage is 25 kV. The structure height is 152 mm, and the disc diameter is 178 mm. The mechanical failing load is 11 kN. This product complies with ANSI C29.5. The creepage distance is 305 mm, while the dry arcing distance is 159 mm. The 25 kV rating is suitable for medium-voltage distribution applications under the ANSI system. The product is used on 25 kV overhead lines and for post insulation in substations. The relatively large disc diameter provides a sufficient creepage distance for outdoor applications. The porcelain material is fired at high temperatures, resulting in a dense body with good mechanical strength. It can withstand higher bending loads, making it suitable for applications that require additional mechanical strength. This Medium Voltage Pin Insulator provides reliable support for 25 kV power distribution networks.

Our technical team pays close attention to long-term operating performance. We conduct mechanical load cycle tests to simulate actual operating conditions. These tests evaluate durability under repeated wind loads and conductor tension. Our physical and chemical laboratory can also test the thermal stability of the ceramic body. The glaze provides good weather resistance and is designed to resist peeling during long-term outdoor exposure. We hold occupational health and safety management certification, and our production processes follow applicable safety requirements. You can specify your preferred packing methods. For example, we can use non-fumigation pallets or custom-sized wooden cases. We can also adapt the packaging to different countries' import requirements.

Normal delivery takes 25 to 35 days. We support mixed orders containing different 55-series models. The minimum order quantity is negotiable. We accept T/T and L/C payment methods. We provide progress updates from production through dispatch, including photos and videos when required. We pack the products with fumigated wooden pallets and corrugated cartons. The outer layer is reinforced with stretch film to provide additional protection during transportation. The warranty period is 12 months. This product offers a practical balance of size and mechanical strength for medium-voltage applications. Our team keeps you informed throughout the entire order process.

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