- Copper clad steel
Copper clad steel, also known as copper covered steel or by its acronym
CCS , is a bimetallic product, mainly used in thewire industry that combines the high mechanical resistance ofsteel with the conductivity and resistance tocorrosion ofcopper .Its main purpose is to be used as a drop wire oftelephone cable s, and inner conductor ofCATV cable.The main producers are located inArgentina [http://www.facbsa.com.ar/index_eng.htm] ,Brazil , andUSA .Uses
Grounding, union of ground rods to metallic structures, meshes, substations, power installations and
lightning arrestor s. This material has proven its aptitude for these purposes. More than 60 years of installations all around the world certify the excellence of this type of installation.Properties
Among the main properties of these conductors the following should be highlighted:
* Good
corrosion resistance of copper
* Highmechanical strength
* High resistance againstmaterial fatigue
* Lower electrical resistance compared to steel wire
* Much lower impedance at high frequencies than that of steel conductors.Advantages
"Note: A valid reference for the following claims would greatly improve their usefulness. See discussion page."
Due to the inseparable union of the two metals, it is theftproof, because it is not practical to recover the copper. So the conductor has very little scrap value. Thus the frequent robberies so common with pure copper conductors are avoided.
The installation with copper steel conductors are safe and fulfills the required specifications of a good grounding. For this reason it is used with preference by utilities and oil companies.
