Hot Dip Galvanized Transmission Power Line Insulator End Fittings

High-voltage lines disc hanging porcelain insulator (ordinary) for the insulation of high voltage overhead transmission and distribution lines and fixed for conductor.

General assemble insulator string on a line for different voltage grade type insulator used for general areas, such as increasing insulator piece number can also improve the pollution flashover performance.

Hanging by the porcelain, porcelain insulator iron cap and steel legs with no less than 525 Portland cement, quartz sand cement gel pack. The contact surface between the iron cap and the steel foot and the adhesive is lightly coated with a buffer layer, and the top of the steel foot is provided with elastic liner. Porcelain surface generally painted white glaze, brown glaze, according to the need to draw other glaze. The surface of iron cap and steel foot is all hot-dip galvanized. The push-pull type elastic locking pin of ball-type connection has two types: w-type and r-type, both of which are made of tin bronze, brass and austenitic stainless steel. Grooved cylindrical and hunchback cotter pins, the former having a hot zinc surface and the latter made of brass. The elastic locking pin, cylinder pin and other parts are supplied with complete sets of products.

Insulator according to the connection points ball type and trough type two kinds.

The same strength grade of regular and fouling resistance type insulator, using the same size ball and socket connections, can guarantee the swap.

The Polymeric Insulator are made of glassfiber epoxy core rod, silicone rubber shed and metal fittings.

The silicon rubber shed adopt the whole packing pressure technique, and then to solve the key problem – interface electric spark puncture, which would affect the reliability of composite insulator.

Connection of the glassfiber rod and metal fittings, adopts the pressure welding technique of the international advanced level, and have the full automatic sound wave detection of defects system, high intension, beautiful outline, small volume, light weight, and the metal fitting of galvanization can corrosion prevention and exchange used with porcelain insulator.

This product is reliable structure, can’t damage the core rod, and take full advantage of the mechanical strength.

We also have kinds of fitting for Insulators,welcome to inquiry,thanks very much!
