What Is Disc Type Insulator?

Disc type insulator are also called suspension insulators. It's actually a piece of porcelain or glass with steel caps and iron feet at the top and bottom. It can be used in tandem. Disc type insulator, is usually made of insulating parts (such as porcelain parts, glass parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) with cement or mechanical clamping. Insulators are widely used in power systems, generally, it belongs to external insulation. It works under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations and external live conductors of various electrical equipment are supported by insulators, insulating it from earth (or ground objects) or other conductors with potential difference. The function of disc type insulator: As one of the important equipments of the transmission line, the disc type insulator is responsible for the important task of the hanging wire and the insulation of the tower. The suspended disc ceramic insulator are used in high voltage, ultra-high voltage and ultra-high voltage transmission lines all over the world, providing a reliable guarantee for the safe operation of transmission lines. The disc ceramic insulator is divided into two kinds: the one for ac system and the one for dc system. The high-resistance insulating material formula, special umbrella structure and anti-corrosion design of metal accessories make the disc ceramic insulator produced by our company completely meet the harsh requirements of the aging performance of the products for the dc power transmission. There are many kinds of umbrella structure design of disc type insulator, providing a variety of reasonable options for the use of various regional lines.
