Protective fittings

Protective fittings are designed to protect insulating suspensions, insulators, wires, lightning protection cables from electrical and mechanical influences that cause deterioration of overhead power lines or damage to individual elements.

Protective fittings:

• corona protection rings and shields used to lowering of electric field intensity on a daisy and protection of accessories against a corona;
• screens attachment – for installation of Shields in a tension suspension string;
• vibration dampers – for warning of damage of wires and lightning protection ropes from the fatigue failures caused by vibration;
• the surge dampers of wires intended for protection against surge of a phase;
• spacers, providing fitting and holding of wires at the given distance from each other;
• arcing horns, protecting insulators of suspension strings of a lightning protection rope from influence of an electric arc;
• the ballasts set on the supporting clamps for the purpose of an exception of «tightening» of wires of the intermediate support;
• safety cable sleeves used to protection of wires against damage in case of contact among themselves and also in case of possible shock about accessories;
• bolted clamps – for an exception of fractures of hollow wires on descents to devices of a high tension on substations.
