10KV-1000KV Toughened Glass Disc Insulators For High Voltage Transmission Line
Disc Suspension Insulator Working Principal
A suspension insulator for an overhead powerline comprises two major components. These are the cross-arms and the disc insulators, which are coupled up by metallic links. These suspension insulator parts work as a system to protect the transmission line.
A complete set of suspension insulator is manufactured by stringing the disc insulators using the metallic string. The connection of the insulators is in series.
For the pole lines where the conductor is suspended from the insulator’s bottom section, cross-arms are used for securing the insulator in place. The cross-arm also guarantees the stability of the insulator.
Each disc for a suspension insulator is designed to have a low voltage. For example, a single disc of the insulator can be calibrated to have 11 kV. The discs are connected in series, and the desired voltage will determine the number of discs to be used on the insulator.
The series connection of the insulation of the discs provides maximum independence of the insulator. This is to say that the performance of one disc does not depend on the others. In the event that one disc fails, the rest will remain unaffected.
