Introduction of rod-shaped porcelain insulators for OCS of electrified railway

The rod-shaped porcelain insulator (hereinafter referred to as insulator) of the overhead contact system of electrified railway consists of seven parts: rod-shaped porcelain parts, steel caps, steel bowls, U-shaped hoops, pressing plates or pins, and fasteners. The rod-shaped porcelain is the key component of the insulator, which not only bears the internal insulation, but also the tensile and bending mechanical loads. Metal accessories are components that connect the insulator with the use environment, also known as connection hardware. The rod-shaped porcelain insulator of OCS of electrified railway is composed of rod-shaped porcelain parts, steel caps and steel bowls, of which no less than 525 Portland cement and porcelain sand. Or bonded with quartz sand glue. Apply a thin buffer layer with adhesive on the contact surface of steel cap and steel foot. Elastic pad on top of steel foot. The porcelain surface is generally covered with white glaze. Brown glaze or blue grey glaze can also be used if required. Steel covers, steel bowls, u-hoops, pressure plates or pins and fasteners are hot-dip galvanized. And has moderate mechanical strength consistent with the structure. In order to ensure that the developed insulator can meet the practical requirements of electrified railway
