Copper steel tape earthing coil

Description

Copper steel tape grounding coil is a bimetallic composite material consisting of an inner steel core and an outer copper layer. It not only has the high mechanical properties of steel, but also the good electrical conductivity and corrosion resistance of copper. In terms of product form, we use one individual package of 100 meters, which contains all the physical properties of copper steel grounding rod and the advantage of the length of copper steel strand.

:

Tensile strength:

350-770 MPa (for vertical grounding); 290-510 MPa (for horizontal grounding)

Copper thickness:

0.254 mm-0.8 mm (custom order is available)

Ductility of copper layer:

when the product is continuously bent by 90° three times, no cracks will occur on the inner and outer edge copper layer.

Weldability of copper layer:

when the product is placed between the clamp or vice jaws, the distance between which is less than the diameter of the steel core of the sample (W=d-0.1), hit the end of the sample with a hammer, cut off a sufficient layer of copper, completely expose the steel core, the presence of a peeled copper layer on the vice jaws is allowed, but the remaining part of the rod, peeled copper and steel should not be visible to the naked eye.

Electrocorrosion characteristics:

when simulating the short-circuit current interruption after the electrocorrosion resistance test, the final resistance growth rate does not exceed 50% of the initial resistance value. Moreover, the resistance growth rate at each stage of the test does not exceed 15% during the test. The surface of the copper-coated steel sample after the test is solid, without cracks, cavities, and defects in the form of bubbles.
