Copper-Clad Steel Grounding Strand/Copper Plated Steel Strand/Copper Clad Steel Strand Wire/Copper Clad Steel Strand Wire

product description

Continuous cast copper-clad steel is produced using 99.99% pure copper and high-quality carbon steel using metallurgical techniques to achieve molecular bonding of copper and steel. The thickness of the copper layer on one side is more than 0.25-1.0mm. The production process is green and environmentally friendly. There is no problem of thin copper layer of electroplated copper-clad steel and serious pollution. It also avoids water seepage at the interface of copper-clad steel cladding of the casing and poor corrosion resistance. ,high quality The service life of continuous cast copper-clad steel can reach 50 years.

Main features

1.Composition: The center is a steel core, the outer layer is a high-purity copper layer, and the proportion of copper reaches 20-55%.

2.Mechanical and physical properties

(1) Tensile test: tensile strength >300MPa.

(2) Bending test: Copper-clad steel rod used for vertical ground electrode, tighten one end of the sample on the clamp or jawUse a force perpendicular to the sample at a distance 40 times the sample diameter from the fixture, bend it at 30° 40 times, and the copper layer will notCracks or peeling.

(3) After rolling the teeth of the rod, the outer surface of the tooth tips and roots will be covered with copper layers, without cracks or exposed steel.

(4) Current impulse test 200KA, 8/20us impulse current test, there is no obvious change in the sample.

(5) Corrosion resistance: Take a section of continuous-cast copper-clad steel and cut it longitudinally to expose the steel core, and bury it in the atmosphere or underground.According to the test, the steel core showed corrosion after 365 days, but no corrosion was found at the joint between copper and steel.

The main purpose

(1) Lightning protection grounding: substations, power towers, railways and airports, high-rise buildings, petrochemical enterprises,

Oil (gas) depots, power plants, nuclear power plants, communication base stations.

(2) Electrical transmission, military communications, signal transmission, broadcasting, television signal transmitting and receiving antennas, feeders, etc.
