Copper clad wire (CCS) is an abbreviation for copper clad
steel wire, which incorporates both the physical property of steel (i.e., high
tensile strength) and the electrical property of copper (i.e., its high
electrical conductivity). In short, copper clad steel wires are steel wires
covered with copper. The core material used to make copper clad steel wire is
generally low carbon steels and is typically employed as either the internal or
grounding conductor of coaxial and multilayer cables.
Copper
clad steel wire can be electroplated or manufactured with silver, nickel,
gold, solder, and tin. The applications of CCS includes specialty resistors and
capacitors, motors and magnetic assemblies, and intelligent pressure and
temperature measuring instrumentations. The electrical resistance to electrical
current passing through the cable when exposed to the electric field depends on
the thickness of the outer layer of copper used in the wire. This layer is
called 'coating' and its thickness depends on the manufacturing process used in
wire making.
The electrical and mechanical properties of copper along
with its ability to form electrical conductors at high temperatures make it a
particularly suitable metal for use as electrical wire conductors. Copper is
used in a wide range of applications, such as power distribution, medical,
aerospace, telecommunication, industrial, and transportation applications. For
instance, many medical applications involving surgical operations require
surgical steel wire to prevent blood loss after surgery. Moreover, due to the
fact that copper is capable of providing much greater electrical resistance
than other metals, the metal is commonly used in motor industries to reduce the
weight and length of engine cables and to enhance the performance and lifespan
of engine components.
With the rapid growth of end-use industries such as
automotive, building and construction, power generation, and
telecommunications, the demand for copper clad steel wires is also increasing.
For instance, according to the European Information Technology Observatory
(EITO), telecommunications revenues (services, hardware, and infrastructure)
increased by 2.0 percent to EUR 59.7 billion in Germany in 2019. In
telecommunications industry, copper clad steel wire is used to produce CATV
drop cable, coaxial cable, telephone drop wire, etc.
