Interested in learning about fire resistant wiring systems in international markets? What are the testing requirements and standards and how do VITALink® products fit in? Read the synopsis of our white paper below and use the link to download.

Synopsis
Many life safety, fire-fighting and critical emergency systems depend on the unfailing reliability of electric cables during a fire. Should these essential cable systems fail because of the fire, the critical equipment they supply power to also fails, leaving occupants, emergency responders, and property at risk.

Installing cables that are not designed to withstand dynamic / flexing applications can lead to failure. Find out what causes Z-Kinking and how Exane's^® PowerFlex and TorqueFlex products help you avoid this costly issue by downloading Marmon Electrical's white paper, "Z-Kinking: Risks to Performance and Prevention" by Damian Billeaudeau, National Sales Manager for Marmon Electrical‘s Oil & Gas group.

In June 2012 UL learned of compatibility issues when Classified Fire-Resistive Cables were installed in systems where zinc was used as in interior coating in rigid steel conduits. At the high temperatures the zinc coating inside the conduit system vaporizes and interacts with the copper conductor creating a brass alloy. Brass melts at a lower temperature, which compromises the integrity of the electrical system causing premature failure. The UL-2196 test is designed to evaluate the performance of electrical circuit protective systems in severe fire events—specifically, when exposed to fire for 2 hours followed by the mechanical shock of a fire hose stream.

UL-2196 Cable Performance Testing Impacts The Following Projects:

There are differences between cables that are flame retardant and those that are fire rated. Flame retardant cables can resist the spread of fire but fire rated cables maintain circuit integrity and continue to work in the presence of fire. This article below will describe the differences between flame retardant and fire rated cables.

It’s important to have fire rated cables that meet UL 2196 and the requirements of the code as well as know which type of cable will work best as well as save you money. Two common types of cables to compare are metal clad (MC) and mineral insulated (MI). Each meets the requirements of the code, but are different when compared to labor costs. Time is money and you can be spending a lot of money for someone to appropriately install a cable. Know what the cost effective solution is between MC and MI cables.

What do stadiums, road way tunnels, subways, high-rise buildings, and other essential structures have in common? Their construction requires fire-resistant wiring. Of course, there are codes and standards which require this, but it’s also common sense.
