DuraSystems’ DuraBarrier is designed for easy installation and is fire, blast, moisture, and impact resistant. DuraBarrier is demountable for easy maintenance or replacement of transformer or equipment. In addition, the DuraBarrier is corrosion resistant, maintenance free, and cost competitive. The standard DuraBarrier is made of hot dipped galvanized, with stainless & specialty metals also available. DuraSystems’ DuraBarrier helps protect life, property, and the environment.
The DuraBarrier was selected by Energy Northwest in Washington State as a transformer separation.
The above options should provide the selection and flexibility to meet virtually all possible transformer applications and its modular design and bolted on site connections make it quick and easy to install.

Transformer Isolation Barriers
DuraSystems` DuraBarrier is a barrier that will help protect people and property from the growing number of transformer failures.
Electricity is taken for granted and it is only when the lights go out and life comes to a standstill that people suddenly become aware of their dependency on electrical equipment such as transformers.
Transformers are a fundamental component of electrical distribution and transmission networks. Most people are not aware of the fact that transformers are subject to faults. Transformers sometimes explode and/or catch fire without warning. When a catastrophic fire or explosion occurs, the damage and costs can be immense. Equipment replacement, cleanup and repair, and lost revenue can run into the 10’s of millions of dollars.
Insurers and corporate risk managers consider transformers to be the most critical electrical components within facilities today. This is due to the quantity of oil contained within the transformer, its contact with high voltage elements and the dangers involved with failure. Transformer continue to fail at an increasing rate year over year.
Two specific transformers statistics that deserve special attention are the current average age of transformers and the increased loads they are expected to supply. The average age of transformers in North America is 35 years, which means that many, with an optimistic life span of 40-50 years are coming to the end of their usefulness. There is also a problem with increased loads. World energy consumption has grown from 1 trillion to 11 trillion kW/hr in the decades following World War II. Transformers were not designed to handle such heavy loads.
These emerging risk factors have caused many insurance companies to demand protection of the transformers they insure. This is why the DuraBarrier was developed. DuraSystems has designed and developed a barrier system that meets the requirements of FM Global Property Loss Data Sheet 5-4 for exterior transformers and most stringent fire protection requirements for fire exposure on both sides.
DuraSystems recognized the need for transformer protection that could be installed in confined spaces and was quick and easy to erect unlike concrete barriers. Due to its relatively low weight, the DuraBarrier requires simpler and smaller foundations than poured concrete or concrete block methods. This can result in significant cost savings especially with retrofit applications where existing equipment is being upgraded/replaced or existing underground service foundations cannot be disturbed.
The DuraBarrier is a modular pre-engineered barrier system. DuraBarrier pre-engineered systems are available to meet the following conditions:
