33kv 45kn Disc Insulator T And C - Porcelain & Glass Material , White Color, Designed For Power Transmission With Enhanced Insulation Performance

A disc insulator, also known as a suspension insulator, is an electrical insulator used in overhead power transmission lines to support and insulate the conductors from the supporting structures, such as towers or poles. It is called a disc insulator because it has a disc-shaped or saucer-shaped design.

The disc insulator is typically made of a high-strength material, such as porcelain or glass, that can withstand mechanical stresses and electrical voltages. Each disc has a smooth, circular surface to prevent the accumulation of contaminants or moisture, which could lead to electrical arcing and flashovers.

The disc insulator provides electrical insulation by creating a barrier between the conductor and the supporting structure. The conductor is attached to the top disc, while the lower disc is connected to the supporting structure. This design prevents the flow of electrical current through the supporting structure, ensuring safe and reliable power transmission.
