Copper Stranded Wire Why Is There A Slippery Wire?
Aug 30, 2017

Why does copper wire appear slip wire?

1, clip hardness is low; when the clip hardness is lower than the hardness of the strand, the clip can not form a scratches on the surface of the strand, copper stranded wire of course, could not bite the strand, copper stranded wire and then when the jack back to the top, The strand is followed by retraction, thus forming a slip wire.

2, tension jack and anchor with different heart or limit plate and work anchor is not heart; when its heart will cause tension when the side of the clip will scratch the strand, and scraping the iron will be filled The teeth of the teeth. Back to the top because the clip teeth teeth filled with iron and can not be embedded in the strand, this time due to high-speed retraction of the stranded strand damage to the teeth of the clip, copper stranded wire resulting in slip wire.

3, the limit plate wear; with the increase in the number of times, under considerable pressure, the support part of the plate will be pressed down, copper stranded wire resulting in smaller limit size. When the tensioning wire is moved backward, the hole of the clip can not be opened, which is smaller than the diameter of the steel hinge. Because the hardness of the clamp is higher than that of the steel hinge, when the jack is forced to move backward with steel hinge, Will scratch the steel hinge line appearance, copper stranded wire resulting in steel hinge wire diameter smaller, copper stranded wire clip teeth filled with iron, back to the top, resulting in slip wire, high-speed retraction of the steel hinge will damage the clip teeth.

4, when the tension in the clip teeth in the butter, sand; use when the clip teeth in the sand or other impurities, impurities filled in the gap between the clip teeth, when back to the top, the clip can not be embedded steel hinge line Produce slippery wire.

5, steel hinge line with rust.copper stranded wire Steel hinge with rust will also be filled with the clip of the teeth gap caused by slip wire.

6, there are mud within the limit plate; copper stranded wire limit plate with mud, the damage is equivalent to the plate wear, will lead to smaller size and produce slip wire.

7, the installation of work clips do not flexible ring; installation work anchor, sometimes in the clip on the elastic circle (oil "0" ring or bead ring) will be damaged or lost, and some workers do not want to flexible ring, When the back to the top, the clip and the steel hinge of the friction force becomes smaller and cause the clip does not follow up. High-speed retraction of the steel hinge will damage the clip teeth, resulting in slip wire.

8, the clip and the work of the anchor is not supporting; in the same site using two kinds of anchors, sometimes management confusion, resulting in the use of clips are not used, copper stranded wire because the two systems may not be the same anchor taper, Strand caused by slippery wire.

9, the operator is not skilled, back to the oil when the buck too fast, the clip too late to anchor the stranded wire, high-speed retraction of the steel hinge will damage the clip teeth, resulting in slip wire.

According to the different characteristics of hard copper wire and soft copper wire, they are used in different areas. Hard copper stranded wire is often used for applications where conductivity is required and relatively high in tension, such as distribution lines and construction conductors, copper stranded wire as well as in the case of transmission Cable. Soft copper wire is usually thinner than hard copper wire, the conductivity is particularly high, there are toughness. What we see most is the household electrical wire, it is also used in electrical machinery, as the power cable and communication equipment, the conductor.

Hard copper stranded wire and soft copper wire in the performance difference is not much difference, not the experience of the manufacturers will easily ignore the gap between the wrong will cause a great loss, so be sure to understand its function to understand which one more Suitable for their own use.

Hard copper strand tensile strength, copper stranded wire high hardness, it is a copper cold drawn from cold processing. Soft copper wire is based on the hard copper stranded by heating out of which the residual, compared to hard copper wire is relatively soft and flexible, can be bent.
