CopperClad wire and strand combines the strength of steel with the conductivity and corrosion resistance of copper. These properties make CopperClad wire and strand ideal for many utility, telecommunication, and general industry applications.

What is CopperClad Wire?

CopperClad wire is a composite in which a concentric copper cladding is metallurgically bonded to a steel core through a continuous, solid-cladding process using pressure rolling for primary bonding. The copper cladding thickness remains constant surrounding the steel. It measures from 6% of the overall wire diameter for 30% conductivity wires, and 10% of the overall wire diameter for 40% conductivity wires. Different steel grades for the steel core result in Dead Soft Annealed, High Strength and Extra High Strength characteristics.

What is CopperClad Strand?

CopperClad strand is concentrically stranded cable of one to three layers with left-hand lay in the outer layer, unless otherwise specified. All individual wires are the same size.

Features

Stronger Than CopperThe steel component of CopperClad wire creates a strong conductor which can withstand more mechanical abuse than solid copper wire. Its superior mechanical strength makes CopperClad wire less likely to be damaged during installation, or fatigue from vibration or bending.

Easy installationCopperClad wire and strand has been specially designed with a low carbon steel core to give the maximum amount of flexibility while maintaining high strength. A special heat treat process results in a very malleable wire that is easy to handle and install without special tools or equipment. CopperClad wire and strand is also lighter than solid copper of the same size.

Theft ResistantBecause the copper cladding is permanently bonded to the central steel core, CopperClad wire and strand offers very little scrap value, discouraging theft and leaving the grounding system intact.

Corrosion ResistantCopperClad wire and strand exhibits the same corrosion resistant properties as copper, but maintains the high strength of steel.

Dead Soft Annealed CopperClad Wire and Strand

CopperClad wire and strand has been utilized and relied upon for years as a strong, non-rusting, efficient grounding conductor. Combining the strength of steel with the conductivity and corrosion resistance of copper, CopperClad wire and strand provides a long-lasting, low impedance path to the earth. It is also less susceptible to theft because it is a bimetallic product and does not have the high scrap value of solid copper. When annealed, CopperClad wire and strand exhibits the flexibility necessary for easy handling.

To eliminate the possibility of damage from lightning strikes or short-circuit conditions, an efficient, reliable grounding system is necessary to rapidly dissipate the surge current to ground. Whatever the grounding application may be, there is a CopperClad conductor available in the size, conductivity and strength that is required.

ApplicationsGrounding Conductors for Primary Surge ArrestersSelecting Dead Soft Annealed (DSA) CopperClad wire as the grounding conductor for primary surge arresters permits a continuous length of conductor to be installed from the arrester to the buried grounding electrode. This is a practice which is not usually recommended with aluminum conductors. The steel core of the DSA CopperClad ground wire provides a rugged lead. It can withstand more mechanical abuse and is less susceptible to vibration-induced fatigue than solid copper or aluminum wire.

When DSA CopperClad wire is used in place of copper, the grounding conductor is far less likely to be stolen. This feature is important not only from an economic standpoint, but also from the standpoint of safety and reliability. Often, the fact that a copper downlead has been removed is not evident until a surge current causes a failure in the system.

Connectors Standard connectors used for copper wire can be used on all CopperClad products. This also includes exothermic connections.

Selecting the Right Size for Your Application Design engineers should be concerned with two factors when selecting a conductor for a ground grid. The conductor must: meet the maximum fault current for a certain duration, and meet a minimum breaking load as required by the substation design (typically 5,000 pounds).

Traditionally, we have used a chart comparing the ampacity ratings of copper and CopperClad CCS that allowed the user to visually select the CopperClad equivalent. For example:

• The equivalent to 4/0 copper per the graph is 19#9 40% DSA

• A typical maximum fault current for a distribution substation is ~18 kA at 30 cycles

• A 2/0 copper or 7#6 CCS conductor will meet this requirement instead of the larger size 4/0 copper commonly used for ground grids

• 7#6 CCS Conductor safety margin—30%

• Most engineers upsize to 4/0 copper in order to meet the mechanical strength requirement

• 7#6 CCS meets the fault current and mechanical strength requirements

Our coated product goes one step further. The grey PVC jacket wrapping the outside of our strong CCS effectively makes the wire in question look at first glance like simple galvanized steel—and as such of no interest to copper thieves.

Cut It—Strip It—Connect It.

We’ve listened to our users, and we know that fast installations mean more ground gets covered when trenching in grounding wire. Time is money. Just cut the wire, strip the PVC coating at the terminal end, and connect it as you would copper. Simple.

Copper Theft

The money lost in copper thefts aren’t even the greatest concern. A recent FBI criminal intelligence assessment warns: “Copper thieves are threatening U.S. critical infrastructure by targeting electrical substations.... The theft of copper from these targets disrupts the flow of electricity... and presents a risk to both public safety and national security."

For a few dollars in money, thieves risk their lives and those of service providers, field workers, and customers. Ungrounded facilities can be an epic disaster in case of fault. In these uncertain times, a safe and steady supply of electricity is paramount to maintaining our way of life. AFL's CopperClad represents another first-line defense in the fight to keep our energy grids safe and secure.

STOP COPPER THEFT ONCE AND FOR ALL

Copperweld® CAMO™ represents a tremendous leap forward in the fight against copper theft. DSA Copperweld® copper-clad steel conductors have been an excellent alternative to copper for grounding applications for almost a century. Providing a low-impedance path to ground, ample fault current capacity and high tensile strength, they're a natural for grounding poles and substations.

We've long marketed Copperweld® as a theft-deterrent. It works on three levels:

• Magnetic — Most thieves now test wire for copper purity by placing a magnet on it. Copper isn't magnetic, steel is.

• Hard to cut — Savvy thieves know when the wire resists their cutters that they're not dealing with soft, pliable copper.

• Low scrap value — If they ignore the signs and cut anyway, the joke will be on them. The scrap value of CopperClad is that of cheap ferrous mixed-metal. It's not worth the risk. So they may cut once, but not again.

The only catch has been the appearance: CCS looks like copper. But no more. Through Fuishi Copperweld's ingenious patent-pending process, we have developed a method of permanently changing the color of the shiny outer copper layer to a dark grey without affecting conductivity or connectivity. The CAMO™ conductors look like low-cost galvanized steel, and thieves will simply walk right past it.

Protect your smart grid the smart way with Copperweld® CAMO™.
