Refractory Concrete Panels

When fire containment is absolutely imperative.

A power substation contains all of the ingredients required to generate the perfect fire storm. A typical transmission transformer bank consists of three or more transformer tanks, each containing 10,000 to 45,000 gallons of mineral oil. The initial spark is likely to come from electric arcing inside the tank, which also generates heat and pressure high enough to rupture the tank. Oxygen immediately rushes into the tank causing the oil within the tank to violently explode, creating a blast of intense radiation, flying shrapnel, and flaming oil. The effect of the blast is instantaneous and has been documented to ignite other transformers more than 60 feet away from the initial fire.

Features & Benefits

Simple, Quick Assembly and Reassembly

  • Results in significant cost savings due to grooved columns and slide-in panels that allow construction of one wall in one day or less.
  • Built from prefabricated components, with standard tools. No special training is necessary.
  • Constructed with low-capacity boom trucks due to light-weight panels and columns.

Versatile and Easily Adapted to Outdoor or Indoor Use

  • Economically meet all mechanical specifications throughout the expected temperature range due to unique refractory design.
  • Applicable to substations with different wall arrangements and dimensions.
  • Easy and safe to adjust in the field with ordinary tools.
  • Field-proven refractory and reinforcement materials - highly superior to concrete and other cements.

Fire Rating

Fire Rating

Certified 4 Hour Fire Rating
Certified by Southwest Research Institute per ASTM E-119 and compliant with IEEE Std 979, IBC, CBC, UBC construction codes. Surpassed both the required 4-hour fire exposure test and the 45 psi water jet blast test at 1,960 F.

Ballistics Testing

Ballistics Testing

Ballistic Impact Resistant
TruFire Walls have sufficient impact resistance to survive shrapnel inpingement and are capable of stopping a 44 Magnum ballistic projectile with no through penetration, which is equivalent to UL Standard 752 rating.
