Abstract
The utility model relates to a pretwisted suspension wire clip for overhead line, composed of a rigid clamping plate, a wire clip main body and an elastic clamping fixture. The elastic clamping fixture is made up by two elastic clip sheets. A shaft groove which a conductor wire can be passed is arranged in the middle. The shape of the outer surface looks like a hyperbola waist drum. The wire clip main body is uniformly arranged and winded to form by a plurality of metal pretwisted wires pretwisted into a spiral shape. The wire clip main body is sheathed outside the elastic clamping fixture, and the wire clip main body is axially extended along both ends of the elastic clamping fixture. A pretwisted wire bunch with a core hole in the shaft direction in the middle is formed. The pretwisted wire bunch is sheathed on the part of the outer of the elastic clamping fixture, and the pretwisted wire bunch is the same configuration as the elastic clamping fixture. The configuration of the pretwisted wire bunch looks like a hyperbola waist drum. The rigid clamping plate made up by two clip sheets is made up with the clamping fixture with a hyperbola waist drum inner cavity. The rigid clamping plate is clamped outside the wire clip main body on the elastic clamping fixture point. The suspension wire clip has large grasp force and light weight, and the suspension wire clip ensures the grasp force, and simultaneously the suspension wire clip can also eliminate the centripetal pressure efficiently. The suspension wire clip increases the rigidity of the suspension point conductor wire / ground wire, and the suspension wire clip is not easy to cause injury at the suspension point, and therefore, the suspension wire clip ensures the normal life time of the system.

Described rigidity clamping plate can also can directly be formed by two rigidity intermediate plate hinges by being placed in its outer U-shaped strap clamp tightly with fixing, can directly be fixed with suspension plate on the rigidity intermediate plate.
For preventing point discharge, the termination of the preformed armor rods of wire clip body is hemisphere.
This overhead transmission line pre-hinged catenarian cable cleat function and characteristics:
1〉this overhead transmission line can substitute the suspension clamp of various versions in the past fully with pre-hinged catenarian cable cleat.
2〉this overhead transmission line wraps lead/ground wire hanging position central authorities formation elastic buffer with the rubber clamp of pre-hinged catenarian cable cleat, avoid contacting of suspension clamp and lead/ground wire rigidity, can eliminate harmful radial pressure effectively again when having guaranteed the wire clamp grip.
3〉this overhead transmission line is wrapped in lead/ground wire outside with preformed armor rods equably with certain length, both improved the rigidity of the hitch point of lead/ground wire, between wire clamp and lead/ground wire, formed sufficient contact-making surface again, with the suffered stress distribution of lead/ground wire on a bigger zone, make bending, shear, the influence of static stresss such as stretching greatly reduces, guarantee that wire clamp itself can be concentrated to the hurtful stress of lead/ground wire, greatly improve the ability of lead/ground wire tolerance stress, and when lead/ground wire vibration takes place even waves, prevent because the stubborn repeatedly folding of lead/ground wire, cause because of fatigue of materials a disconnected burst of phenomenon takes place, and be difficult for causing damage, thereby protect the ordinary life of positive system in suspension place.
4〉this overhead transmission line dolioform particular design of hyperbola of pre-hinged catenarian cable cleat, grip is big, and is in light weight, can reduce electromagnetic consumable and eliminate corona, and the spherical termination of protecting lines guarantees the unlikely generation point discharge of lead/ground wire.
5〉this overhead transmission line pre-hinged catenarian cable cleat installation quality high conformity, and installation process can damage wires/ground wire.
6〉this overhead transmission line has a very high reliability with pre-hinged catenarian cable cleat is in service, and defeated, distribution line are had excellent protection, thereby guarantees the good economy of power system operation.
7〉this overhead transmission line is in full accord with pre-hinged catenarian cable cleat material and institute's wrappage (twisted wire), has reduced owing to metal not of the same race caused corrosion under electric circumstance, thereby has guaranteed stronger corrosion resistance, has prolonged the useful life of system.
8〉this overhead transmission line has advantages such as grip is big, easy for installation, freight is low, neat and artistic with pre-hinged catenarian cable cleat.
9〉this overhead transmission line is running under extreme rugged environment, tension force, impact, the extreme temperature with pre-hinged catenarian cable cleat, and pre-hinged catenarian cable cleat still can normally move.
10〉this overhead transmission line has avoided bolt, nut, packing ring and other parts in the possibility of installing or operation is lost or damaged therebetween with the particular design of pre-hinged catenarian cable cleat.
11〉this overhead transmission line is made by the high duty metal silk with the lines that protect of pre-hinged catenarian cable cleat, has fabulous elasticity and toughness, can guarantee long-term ageing resistance and anti-loosening property.
12〉this overhead transmission line is in light weight with pre-hinged catenarian cable cleat, intensity is high, can be used for the bigger area of heavy ice and span.
13〉this overhead transmission line is held lead/ground wire with the lines that protect of pre-hinged catenarian cable cleat in a both sides of dangling, and has avoided lead/ground wire slippage and play, therefore bottom line is reduced in the wearing and tearing of lead/ground wire.
