Worldwide regulations require fire protection for emergency feeder circuits in commercial buildings, public spaces, hospitals, industrial plants and refineries. Critical equipment and processes must continue to operate during an emergency to minimize damage and protect lives.
Historically, fire safety of critical circuits was achieved by running conventional cables behind a heat barrier such as a gypsum board or hollow concrete block; or by embedding the conductors in concrete.
nVent PYROTENAX mineral insulated fire-rated cables are UL listed and can withstand temperatures up to 1850°F (1010°C) for two hours. This built-in fire resistance provides greater protection as opposed to the fire-rating of conventional cables which require heat barrier systems.
nVent's PYROTENAX mineral insulated fire rated cable offers a unique combination of dependability, versatility and performance. Highly compacted magnesium oxide insulation provides exceptional temperature and electrical performance. This inorganic and inherently fire resistant construction features:
As codes increasingly call for two hour fire resistance, the demand for a more costly and more complex construction for adequate protection of conventional cables. PYROTENAX fire-rated cables have built-in fire resistance and do not require a fire barrier.
PYROTENAX cables have a proven track record, with millions of feet installed globally.
PYROTENAX cables are:
The cable itself is a fire barrier (built-in fire resistance) and does not require additional construction methods. While conventional cables require heat barrier systems such as gyproc enclosures, or encasement in two inches of concrete, which takes up space, our cables are a built with a fire-resistant barrier, meaning additional construction methods are not required.
Construction methods: Just because they meet the code, does that mean they provide two hours of protection?
