Tension resisting clip for carbon fiber composite core conductive wire

Abstract

The invention discloses a strain clamp used by a carbon fiber composite core lead for fixing carbon fiber composite core aluminum strands on overhead power lines and strain poles and towers of a substation in the electric power system. The clamp of the invention is composed of a sphenoid clip holder provided in a wire clamp body, a sphenoid clip in the clip holder with a shape matching the shape of inner holes of the sphenoid clip holder and an internal liner pipe provided additionally. The wire clamp of the invention fully utilizes the feature that the sphenoid clip moves inside of the clip holder to clamp the carbon fiber composite core reliably under the change of temperature, forms a conductor by the crimp connection of the internal liner pipe with the wire clamp body and the aluminum strands, and imposes no damage to the carbon fiber composite core. The wire clamp of the invention has the advantages of compact and reasonable design, novel and ingenious construction, small impact from temperature, strong shock and endurance resistance, even grip distribution, strong bearing grip strength and effective avoidance of grip looseness. Furthermore, the wire clamp of the invention, in the situation that a system increases capacity, needs not to replace an iron tower, imposes no damage to green land and reduces economic loss, thus being economical and practical. The development prospect thereof is broad and an extensive application is available.

Description

Technical field: [0001] The invention relates to a tension clamp used for fixing steel-cored aluminum stranded wires on overhead power lines and substation tension towers in a power system. Background technique: [0002] The strain clamp is a fitting used for fixing wires on overhead power lines and substation tension towers in the power system. It connects the wires to the insulator strings, and the insulator strings are then connected to the iron tower to bear the tension of the wires and reduce the wire tension. It plays a very important role in the safe operation of the power system. For a long time, the above-mentioned wires have been made of steel-cored aluminum stranded wires. Due to the magnetic loss of steel-cored aluminum stranded wires, the long-term operation line loss is relatively large. When the temperature is high, the slack of the line will also increase, which will affect the operation of the power system. In order to eliminate the hidden danger, it is nec...
