Wire and Cable Management Buyer’s Guide 2021

Wire and cable management decisions can seem small, but they have both short- and long-term ramifications, from boosting installation efficiencies and cutting site-prep costs to reducing O&M burdens and improving a project’s levelized cost of energy (LCOE). We reached out to providers of wire and cable management systems for residential to utility-scale solar to see what’s new in their lineup, what it’s made of, how it installs and what sets it apart.

Heyco UVX clip

Heyco Helios UVX Clip

Material: Constructed from our UVX nylon material, the Heyco Helios UVX Clip is ideal for extreme conditions. The temperature range for Heyco Helios UVX Clip is from -4°F (-20°C) to 185°F (85°C). Heyco Helios UVX Clips are part of Heyco’s 20 Year Solar Warranty.

Install: The Heyco Helios UVX Clip accommodates up to two cables between .23” (5,8mm) and .32” (8,0mm) in diameter and mounts into a .260” (6,6mm) mounting hole. The configuration of the fins for the mounting platform allow for easy insertion but high extraction forces while the design of where installers load the cables allows for easy loading of cables but promising holding power. The Heyco Helios UVX Clip is a perfect solution for hard to reach areas. *Spoiler alert* Heyco will also soon have an adhesive backed option utilizing VHB tape for applications where mounting holes aren’t available, making them even easier to install.

Key feature: Despite not being constructed from a stainless-steel material, the Heyco Helios UVX Clip still boasts a 20 year warranty at a favorable price-point.

The cable cross section is 10 AWG/6 mm² and is cTÜVus certified. PV-K/ILF is for application up to 30A. Custom amperage and cable length are available upon request.

Install: The installation is quick and easy; it takes just few seconds to click in the MC4 connectors on both ends of the in-line-fuse PV-K/ILF and it is ready to go. When installing more than two strings in paralleled, install one per-string to protect modules and inverters from costly over current damage.

Key feature: Staubli’s in-line-fuse PV-K/ILF is UL listed and 100 percent made in United States. MC4 connector comes standard with the in-line-fuse PV-K/ILF, and installers can readily find matching MC4 connectors to avoid mating connectors from different brand together.

CAB-Torque-Tube-HangersPatentPend

CAB Solar Torque Tube Hangers

Material: CAB Torque Tube Hangers are manufactured from class 3 galvanized, high tensile strength spring steel for maximum strength and corrosion resistance. CAB’s 80 mil (2 mm) thick PVC coating is applied to 100 percent of the surface for flame retardance, chemical resistance and UV stabilization. They are also high dielectric grade with a dielectric breakdown strength of 400 volts per mil (.025mm). The working load limit of CAB’s Torque Tube Hangers varies by hanger, but most have a limit of 20-25 lbs (9-11.3 kg).

Install: CAB Hangers install quickly and easily with no tools required. They feature a tight snap on fit over most torque tube or fixed tilt structures. Hangers can be installed, and cables loaded in just seconds. This greatly reduces labor time compared to cable ties, clips or clamps. Typical single cable spacing interval is determined by the specific project needs but is generally 2 ft. to 3 ft. The spiral design secures large bundles of cable safely and effectively, and simplifies upgrades, maintenance, and troubleshooting.

Key feature: CAB Torque Tube Hangers are especially effective in projects with bifacial panels because cables are bundled together and neatly organized along the torque tube. This reduces shadowing, a common problem with typical cabling and fastener systems. In addition, CAB Torque Tube Hangers are not only offered in single carrier styles, but also in double and multi-carrier. Custom configurations available for any torque tube or fixed tilt structure.

Heyco Edge clips

Heyco Edge Clips

Material: The mounting device for Heyco Edge Clips is constructed out of a post nickel-plated steel – this steel clip provides high retention forces while requiring low insertion force. This post nickel-plated steel mounting device is then inserted into an ergonomic housing constructed out of Nylon 6/6 UV resistant and heat stabilized material. The cable ties are constructed from a Nylon 6/6 UV resistant material, with plans to offer a Nylon 12 cable tie in the near future. The temperature ratings for Heyco’s current offering are -40°F to 185°F for the cable ties and -.04°F to 221°F for the edge clip.

Install: Heyco Edge Clips are ideal for installations where pre-drilled mounting holes aren’t available or temperatures are too extreme for adhesive solutions. Heyco Edge Clips come pre-assembled with the cable tie already inserted, so all the installer needs to do is push the edge clip onto an exposed edge, route the cables, and then zip the cable tie shut.

Key feature: Heyco Edge Clips are versatile – with two different sizes to choose from (1-3 mm panel thicknesses or 3-6 mm panel thicknesses), installers can use these on the back of PV modules or use them on thicker materials like on purlins or module supports. Heyco Edge Clips are a great solution for managing bare cables or routing conduit, tubing, or sleeving as well.

PVDF_hellermanntyton

HellermannTyton PVDF Solar Tie

Material: Manufactured from polyvinylidene chloride, or PVDF, this outdoor tie exhibits high UV, chemical and thermal resistance for a polymer, with a maximum operating temperature of 284°F. This product is offered with a 25-year warranty.

Install: It was designed to replace metal ties, known to sometimes slice through electrified solar cables and lead to catastrophic faults. Some metal ties require a hand tool to crimp them closed, a time-consuming inconvenience.

Key feature: The key feature of PVDF is the ease of use. When you typically think of metal cable ties, or coated metal products, they are rigid and often times sharp. Plus, you need a tool mechanically close it. With our PVDF Solar Tie, it operates just like a regular cable tie, but will perform for a very long time.

Clip_PD_G-CMEA24BT2S--INDL-O-HIR-ENG

Panduit Edge Clip Cable Tie Mounts

Material: These edge clips are made of a plastic housing that hosts a steel clip and include a pre-installed cable tie. The plastic housing and the cable tie are made of a high-grade nylon that is UV resistant for long-term outdoor exposure and can handle 239° F continuous use operating temperature.

Install: Think of a solar frame edge – these clips install right onto the edge where PV or other wire is being routed along, which allows the convenience of location, ease of installation (no drilling, no adhesives) and then securing the wire with the cable tie. Simply push the edge clip onto the frame edge for a reliable hold. There are two basic sizes for the edge clip, one size designated for panel thickness ranging from 0.7 mm to 3 mm, and the other for a larger 3 mm – 6 mm frame thickness. Different configurations are available in accordance with how the wire run will be positioned relative to the frame edge.

Key feature: Panduit Edge Clips provide versatile mounting direct to panel and frame edges. Where a panel edge is available, paired with a need to route wire or cable alongside or perpendicular to that edge, look to edge clips as the solution. Simply push the mount right onto the edge for a secure hold.

    Chris:
    Read your articles on wire management and Hellermann Tytons PVDF cable tie. We have had a PVDF cable tie since 2017, much sooner than Hellermann’s. In fact, 8,000 were installed in a field test with First Solar in Southern California. Would like to see you do an article of our SolarSafe Kynar cable ties.
