Why Your Company Should Avoid CCA Cabling – Part 2

30 Oct 2018

Cat6 Office Cabling Dallas TX Pittsburgh PA As discussed in Part 1, companies that have a limited budget for network infrastructure may end up buying copper clad aluminum (CCA) cabling to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets. Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Shortened Cable Runs

As lengthier CCA cable runs approach the 100-meter maximum, there will be a decrease of signal strength in comparison to solid copper CAT5e cabling. Reduced signal strength can result in data loss because increased packets of data must be retransmitted.

Unsuitable for Power Over Ethernet (PoE)

Since CCA wires have a higher DC resistance (about 55% greater) than solid copper, its conductors may need to be 60% larger than solid copper to compensate. Without resistance compensation, the drop in voltage will be greater for any channel length.

Longer cable runs of 65 meters or more will surpass TIA’s channel DCR requirements, limiting the available voltage for the device. In addition, higher resistance will result in a faster buildup of radiant heat, which may damage the device.

How to Identify CCA Cabling

CCA wire is also much more brittle than solid copper wire. Identifying CCA is easy because all you need to find is the silver color of the tip of the conductor. Another way is scraping away the thin copper surface of the conductor to reveal the aluminum.

CCA cables also weigh much less than solid copper cables. Go to the CCCA website for the CableCheck™ mobile app (http://cccassoc.org/news/free-apps/), which provides the approximate correct box weights to help detect CCA conductors being used to fraudulently substitute for solid copper conductors.

When a CCA cable is labeled as a Category 5e, 6 or 6A cable or CMP or CMR rated, it is counterfeit cable. It will also be non-compliant with industry performance standards and will pose a hazard by being unable to pass UL fire safety testing.

Why Your Company Should Avoid CCA Cabling – Part 1

Cabling Network Cable Twisted Pairs If your company has a limited budget for network infrastructure, your team may be tempted to find numerous way to economize. Unfortunately, this may lead to buying CCA cabling in order to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets.

Definition of CCA

CCA stands for copper coated aluminum. A CCA cable’s core is an inner aluminum conductor that is coated with copper. As a result, it weighs considerably less than solid copper cables.

A CCA cable can be made at a significantly reduced cost than the solid copper version. This gives a manufacturer an increased profit margin and a significant competitive edge over those companies who continue making solid copper cable.

CCA cables may look similar and are advertised to function just like standard CAT5e or CAT6 cabling, but they have serious flaws that could result in network issues, business continuity problems, and safety hazards as discussed below.

Non-Compliant

CCA twisted pair cables are non-compliant with UL and TIA standards, which require solid or stranded copper conductors. The National Electrical Code (NEC) also does not provide CCA cabling a valid safety listing. Thus, CCA cables cannot be installed legally if the facility requires CM, CMG, CMP, CMR, or CMX rated cables.

Inflexible

As CCA conductors are brittle and easily break, just transferring a faceplate or patch panel can result in failures. CCA wires have low tensile strength, and they are known to break from shearing or pulling, which can happen during packaging or delivery. Moreover, CCA cables have a very limited bend radius.

Oxidation

Aluminum begins oxidizing very rapidly when it is exposed to air. This oxidation and the resulting corrosion may lead to failed terminations inside the network infrastructure, resulting in connectivity issues.

Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.
