At present, there are many kinds of tensioning wire clips for power fittings and their functions are different, but the commonly used ones are NLL aluminum alloy tensioning wire clips, copper and aluminum equipment wire clips (brazing), NXJ overhead insulation wedge type wire clips, etc. The tension clamp is used to fix the wire, in order to bear the wire tension of a kind of power fittings, installation is the construction personnel will first take the device to the specified position, and then through the tool for installation; The following small series and you talk about the three commonly used wire clips:

Electric power fittings tensioning line clip which a few?

NLL aluminum alloy tension clamp

NLL series bolt type aluminum alloy tension wire clamp is suitable for fixing aluminum stranded wire or steel core aluminum stranded wire on the tension rod, used for overhead insulated aluminum wire and insulation cover matching use, play the role of insulation protection; After 1008 hours of artificial climate aging test, the performance is good, this is NLL aluminum alloy tensile wire clip weather resistance; The clamping force is constant, the DC resistance ratio is between 0.85~0.9, and the contact surface between the wire clamp and the wire is large; The overload capacity reaches more than 2 times of the approved current; Always running below dc resistivity ratio 1, thermal cycling performance is very good; No electromagnetic loss, corrosion, oxidation resistance, because the material is made of high strength special aluminum alloy;

Copper and aluminum equipment wire clamp (brazing)

Made of red copper + aluminum, aluminum plate body is set, one end of the aluminum plate body can be detachable through bolts connected with the pressure plate, aluminum plate body is provided with a groove on the surface of the other end of the aluminum plate body is provided with a copper layer, copper layer and groove is located in the same surface of the aluminum plate body; Copper and aluminum equipment wire clamp is mainly used for wiring and electrical equipment outlet terminal connection;

NXJ overhead insulated wedge clamp

The shell is made of high strength aluminum alloy with oxidation resistance and no power loss. Power frequency voltage ≥18KV, guarantee 1 minute no breakdown; The cable does not need to strip the insulation layer, can be directly installed wedge structure, simple and reliable installation; Install connect rod connected to the connection hardware, hardware connected to insulator, ontology opening down as far as possible, with the line in tightener to appropriate location, insulated wires in the body cavity, and then into the insulating wedge core, two wedge core to maintain flush at the same time, to guarantee good knock knock insulating wedge core after flush, then remove the tightener, adjusting nut to chi degree meet the engineering requirements, To ensure that the core is not pulled after the wire is pulled by the tensioning cable clamp, it is recommended to reserve at least 1 meter of wire at the end of the wedge jumper.
