The Shady Tactics Low-Voltage Contractors Use to Undercut Pricing
In the world of structured cabling, not all cables are created equal. Some low-voltage contractors know how to cut corners to offer seemingly attractive pricing. At GETDSI, we’re all about quality, which means we don’t play that game. Let’s dive into the sneaky tactics some contractors use and why they can leave you with a network that’s more trouble than it’s worth.

1. The Copper-Clad Aluminum (CCA) Con Job
One of the biggest red flags is the use of copper-clad aluminum (CCA) cables. These cables may look similar to solid copper but are essentially a thin layer of copper wrapped around an aluminum core. While this might save a contractor a few bucks upfront, it leads to several headaches down the line:
- Lower conductivity: CCA cables simply can’t match the electrical efficiency of solid copper, which can result in spotty connections and slower speeds.
- Brittleness: CCA is more prone to breakage, especially when bent or subjected to stress. This means you could be facing unexpected replacements sooner than you’d like.
- PoE problems: If you plan on using Power over Ethernet (PoE), CCA cables can overheat, leading to failures that disrupt your entire network.
2. Ignoring Industry Standards
Many contractors also choose to ignore established industry standards, which are in place to ensure safety and performance. Here are some common shortcuts they take:
- Neglecting bend radius: Every cable has a minimum bend radius it must adhere to in order to function correctly. Contractors who don’t follow this can cause permanent damage to the cables, leading to poor performance and costly repairs.
- Improper cable separation: Ethernet cables need to be kept away from power cables to prevent electromagnetic interference. Some contractors skip this step, risking data loss and unreliable connections.
- Skipping labeling and documentation: Proper labeling and documentation are crucial for future troubleshooting. Contractors who cut corners here make it nearly impossible to identify issues when they arise, turning your network into a tangled mess.
3. Plenum vs. Riser: The Cable Showdown
When it comes to structured cabling, you’ve got two heavyweights in the ring: plenum-rated and riser-rated cables. Here’s the lowdown:
- Plenum-Rated Cables: These guys are the safety-conscious champs, designed for air-handling spaces (think above your ceiling tiles or below your floorboards). They come with special insulation that’s flame-retardant and produces less smoke if things go south. If your cables are running where the air circulates, you want plenum-rated.
- Riser-Rated Cables: These are the no-nonsense types designed for vertical runs between floors. They’re also flame-retardant but don’t have the same level of safety as their plenum buddies. Use riser-rated cables when you’re running vertically, but keep them away from plenum spaces!
4. The Hidden Costs of Cutting Corners
Failing to adhere to these standards can leave you with a cabling system that’s riddled with problems and ultimately costs you more in the long run. Plus, let’s not forget about the 23 AWG wire gauge! This little wire can make a big difference in your setup:
- What’s the Deal?: 23 AWG is a measure of wire thickness that provides excellent performance in low-voltage applications. With a bandwidth capability of 400-500 MHz, it can handle high-speed data transmission with ease.
