Glass disc insulators are used for insulating and fixing wires in high voltage overhead transmission and distribution lines. Different types of glass disc insulators are used on different voltage levels.

Polymer insulators have high dielectric strength. When the voltage applied to both sides of an insulator reaches a critical value, local conduction occurs, the current suddenly increases, and permanent damage occurs. This phenomenon is called dielectric breakdown. Dielectric strength is the limit that characterizes the voltage resistance of an insulating material, expressed as the ratio of the breakdown voltage of the dielectric in a uniform electric field to the thickness of the dielectric. Under standard conditions, the dielectric strength of air is approximately 32 kV/cm, while the dielectric strength of polymer insulators is generally between 200 and 1500 kV/cm.

The low-voltage winding of oil-immersed transformer generally adopts the cylindrical structure with copper foil around the shaft except copper wire for small capacity. The high-voltage winding adopts multi-layer cylindrical structure, so that the ampere-turns distribution of the winding is balanced, with small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.
