Engineering, Procurement and Construction (EPC) communities are tasked with the responsibility to deliver robust, reliable physical infrastructure solutions that safely and securely route, manage, and protect (the 3-phase AC) medium voltage cables.

These cable installations are often deployed in harsh environments and reside close to personnel, making it critical that the health and safety of workers and equipment is protected.  Common applications include:

  • Military and commercial shipbuilding
  • Upstream / downstream oil, gas, and petrochemical facilities
  • Offshore oil rigs
  • Floating production, storage, and offloading facilities (FSPOs)
  • Wind Farms

When a short circuit occurs in 3-phase AC systems, cables repel each other with tremendous force:

Cable Size Cable Tie Spacing Fault Current Force on the Tie
mm2 mm in. kA N lb
300 300 12 25 865 195
50 3,465 780
75 7,796 1,754
600 24 25 1,732 390
50 6,929 1,559
75 15,591 3,508
1000 39 25 2,887 650
50 11,549 2,599
75 25,985 5,847

 

Cable restraint devices must be able to withstand these forces during a short circuit event, protecting the health and safety of workers and equipment. Most specifies and engineers are diligent when it comes to system design. Problems usually arise when the specification reaches others that might not have the technical understanding and instead focus more on cost.

Panduit Self-Locking Cable Ties and the MS75 Metal Strapping System can now be used for cable management applications requiring short circuit protection. These Panduit short circuit solutions provide a significant cost advantage over conventional cable cleats:

  • Up to 3x faster installation over cable cleats
  • As much as 300% increase in labor efficiency
  • Up to 75% reduction in material cost

Available in a variety of sizes, these solutions ensure cables remain contained in the event of a short circuit occurrence, minimizing disruption and damage to the facility. The Self-Locking Cable Ties and the MS75 Metal Strapping System is engineered to withstand peak currents up to 112kA and can be used with a variety of ladder rack and cable tray styles. This Panduit short circuit solution is designed to perform in a wide range of harsh environments, including industries such as Oil and Gas, Power Generation, Manufacturing, and Shipbuilding.

These Panduit short circuit solutions have been validated at third party test facilities in both the United States and Europe, to provide the utmost confi­dence, that these solutions will perform to specifications when needed. To appreciate the maximum efficiency over conventional cable cleats, Panduit offers a range of high speed installation tools, designed to enable the installer to quickly and safely install these solutions. These tools are both rugged and reliable, ensuring the productivity needed to get the job done on time.
