Problems solved by technology

[0003] However, at present, the traditional compression type and bolt type clamps in the power industry cannot effectively hold this kind of wire. The existing special wedge-shaped composite core strengthened cable connection and tension clamps have high manufacturing costs and high installation process requirements. Harsh, seriously affecting the promotion of composite core reinforced cables

Abstract

The invention discloses a strain clamp for a composite-core reinforced cable. The strain clamp comprises a tension layer, a flow-guide aluminium sleeve and a carbon core protection cap, wherein the carbon core protection cap is arranged at the end part of the exposed composite core in a sleeving manner; the tension layer winds the outer surface of the exposed composite core at the connecting end of the composite-core reinforced cable; a part of the flow-guide aluminium sleeve is arranged outside the tension layer in a sleeving manner while the other part of the flow-guide aluminium sleeve is arranged outside an aluminium conductor at the connecting end of the composite-core reinforced cable in a sleeving manner; when the strain clamp is installed, the conductor at the connecting end of the composite-core reinforced cable is stripped for a set length; then carbon core protection cap is arranged at the end part of the exposed composite core in a sleeving manner; then the tension layer winds the outer surface of the exposed composite core; and finally, the flow-guide aluminium sleeve is arranged in the junction place between the end part of the tension layer and the end part of the non-stripped conductor in a sleeving manner, and the junction place is pressed and connected so as to connect the tension layer with the conductor on the outer layer of the cable. The strain clamp provided by the invention is simple in structure and convenient to install and maintain.

Description

technical field [0001] The invention relates to a strain-resistant clamp for connecting, fixing and tensioning an overhead power transmission and distribution line to a composite core reinforced cable. Background technique [0002] The mechanical part of the composite core reinforced cable is made of a single composite mandrel or multi-strand composite mandrel, which has a very low thermal expansion rate, high strength, light weight, strong corrosion resistance, Non-magnetic, strong flexibility, high elasticity and other characteristics, for the erection of new lines due to light weight and small sag, it has the advantages of reducing the height of the iron tower and widening the span between the iron towers, thereby reducing the cost of the iron tower. The coefficient is low, it can withstand high temperature and short-term overload, and the arc sag can also be guaranteed at a safe height. The replacement of the wire has the advantages of reducing the load of the iron to...
