Suspension insulator for power lines - has two flexible arched insulation members with convex sides outside

摘要

The insulator comprises two flexible, arched insulation members rigidly attached to each other, with their convex sides being on the outside, like in a spring suspension (rigging). The fittings intended for the mechanical connection of the insulator to the cross-arm of a support and for suspending the wire to the insulator are mounted in the middle of the insulation members. The insulation members are made of an elastic insulation material, for example, unidirectional glass-reinforced plastic, in which the glass fibres extend along a rod and are pretensioned to ensure an increased bending strength.
