Power Cabinets Protected with T-Series Fire Suppression System

The fire risked identified in this application was potential electrical faults. Electrical faults can be caused by aging wiring connections, exposed wires, heat build-up and debris. Further to this Eltek identified risk through vandalism and accident that may occur. Some of these risks are hard to reduce, however it was decided that the best way to protect against the migration of fire was to install a BlazeCut system. Whilst the product produced by Eltek is of the highest quality, the environment it was installed into was prone to potential vandalism and risk of electrical fire from damage.

Eltek is a global manufacturer of high-efficiency power cabinets with around 2,000 employees operating across more than 40 countries. Part of the Delta Group since 2015, Eltek is headquartered in Drammen, Norway, with regional offices in Dallas and Singapore.

Eltek invented high-efficiency power conversion and has built its reputation on premium power solutions for some of the most demanding industries in the world, including telecommunications, data centers, power utilities, rail, marine and offshore, and rural electrification. With active business in more than 100 countries, their equipment is running in environments where reliability is not a preference. It is a requirement.

When the power infrastructure goes down, everything downstream goes with it. That is the environment Eltek builds for, and it is exactly the kind of environment where fire protection inside the cabinet is not an afterthought.

Power cabinets are dense environments. Switches, batteries, and electrical components packed into an enclosed space create multiple potential ignition points, and a fire inside a cabinet in a remote or unmanned location can run unchecked for a long time before anyone responds.

For Eltek's cabinets, a BlazeCut T Series system in a 5-meter length containing 1.25kg of FK-5-1-12 was threaded through the interior of the cabinet, routing around and between the components to cover several risk areas with a single continuous system. The tube was clipped directly to the tracks holding the switching gear, using the existing structure of the cabinet rather than adding hardware. No heavy clamps, no mounting brackets, no modifications to the cabinet itself.

That installation approach matters when you are deploying across a global footprint. Fast to install, nothing extra required, and once it is in, it runs without any maintenance intervention for up to 10 years. For a company like Eltek whose equipment operates in telco towers, rural electrification sites, and offshore installations across more than 100 countries, a suppression system that demands ongoing attention is not a practical solution. One that installs quickly and protects continuously is.

The Result

Eltek's power cabinets are now protected by a BlazeCut T Series system installed entirely within the cabinet enclosure. No external drilling, no additional fixing points, nothing added to the outside of the cabinet. The system lives inside, out of the way, and does not change the footprint or serviceability of the equipment.

If a fire starts inside the cabinet, the BlazeTube responds at the point of highest heat and discharges the FK-5-1-12 agent directly onto the source automatically. No alert needs to be sent. No technician needs to be dispatched. The suppression happens before the fire has a chance to damage the switching gear, the batteries, or the components the cabinet exists to protect.

For equipment running in remote locations with no personnel on site, that is the only kind of fire protection that actually works.
