What is a disc insulator？

Disc insulators are also called suspension insulators, which are actually a piece of porcelain or glass with steel caps and iron feet at the upper and lower ends, which can be connected in series.

Suspension insulators are generally made of insulating parts (such as porcelain parts, glass parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued with glue or mechanically clamped. Insulators are widely used in power systems, generally belong to external insulation, and work under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth (or ground) or other conductors with potential differences.

Effect:

As one of the important equipment of transmission lines, suspension insulators are responsible for the important tasks of suspending wires and insulating towers. The suspension porcelain insulators produced are used in high-voltage, ultra-high-voltage and ultra-high-voltage transmission lines all over the world. Safe operation provides a reliable guarantee.

Suspension porcelain insulators are divided into two types: insulators for AC systems and porcelain insulators for DC systems. The high-resistance insulating material formula, the special umbrella-shaped structure and the anti-corrosion design of the metal accessories enable the DC porcelain insulators produced by our company to fully meet the stringent requirements of DC transmission for product aging performance.
