33kv 90kn Disc Insulator T And C

The disc insulator is typically made of a high-strength material, such as porcelain or glass, that can withstand mechanical stresses and electrical voltages. It consists of a number of insulating discs stacked on top of each other and held together with a metal or composite rod passing through their centers. 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.
