Seismic bracing systems are used to limit movement during seismic events, like earthquakes or landslides, protecting environments from property damage, and saving lives. Seismic Bracing Systems may be used for electrical cable trays, fire sprinkler systems, plumbing, and suspended equipment. However, they are most often used in the earthquake and seismic event danger zones or in applications used underground.
Our Custom Seismic Cable Solution
As a distributor for mining parts, one customer relied on Allied Wire and Cable to make a quality custom cable for their application. The bracing system used in this application would be used in an underground mine to assist in emergency operations. The customer knew they could not find their exact requirements in an off-the-shelf product, so they contacted Allied Wire and Cable. They were looking for a cable that offered color-coded and number-coded conductors, specific shielding, and drain wires.
At the core of this UL style, PTLC cable was a 3-pair 20 AWG stranded (7/28) bare copper conductor. Each pair of conductors was color-coded, one black and one white, and each pair was number-coded to stand apart from the other pairs. Each pair featured a tinned copper drain wire and were individually shielded with aluminum and polyester. Additionally, an overall continuous foil shield of aluminum and mylar with an additional drain wire was added. The custom seismic cable’s application did not need high-temperature materials, so the insulation and jacket were made of standard PVC.
When it comes to potentially hazardous work environments, stock products do not always meet specifications and safety standards.
