FIELD: electricity.
SUBSTANCE: polyethylene suspended insulator for overhead transmission lines is proposed, its cap and core are made from composite materials and the insulating part is made from cross-linked polyethylene. The head of the insulating part is pressed-in between the cap and the core when being manufactured. The core is formed by unidirectional reinforcing fibres and a polymeric compound.
EFFECT: improved operation reliability, longer and more stable preservation of the insulating ability and easy use due to the reduced weight of the unit, prevention of corrosion, higher resistance to dynamic loads.
