Cable Cleats
Protect your investments
Dingdong cable cleats are designed to support and retain your cables within your cable tray system in everyday conditions. More importantly, they help prevent damage in short circuit conditions. Unfortunately, short circuits do happen, and when they do,they are destructive and dangerous. Cable cleats are one of the first lines of defense to help protect your personnel,your cables and your cable tray systems.
Cable cleat selection and specification
Step1: Know your cables
What type of cable is being used?
- Single or Multi-conductor
What is the outside diameter of the cable(s)?
What is the cable arrangement (single conductor cable only)?
-Flat or Trefoil
If a ground wire will be installed within the cleat, you will need the ground wire outside diameter
Step2: Know your system
What is the available short circuit current (RMS or ip (Peak))?
What type of cable installed? Cable tray or bracket ?
Step3: Select your cable cleat
- Single cable used Trefoil cable cleat
-Multi-conductor cable used Single cable cleat
Step4: Determine cleat spacing for installation
Your cable diameter is equal to the spacing between conductor centers shown below.
Find your cable diameter at the top of the table and look down at the column below it.
Find the value equal to or greater than the available short circuit for your system .
