Barriers bring benefits to transformer blast protection

08 December 2009

Promat UK has revealed that its Promat Durasteel barrier systems are proving increasingly popular for applications where they provide protection against the devastating effects of power transformer explosions.

The Promat Durasteel barrier systems offer both cost and space savings when used on transformer applications. They are particularly effective when installed between transformers located adjacent to each other in the traditional manner, as they help isolate the blast and potential damage by preventing it from spreading via a domino effect.
The relatively light weight of the Promat Durasteel barriers allows simpler and smaller foundations to be used when compared to traditional poured concrete or concrete block barriers and this can generate significant cost savings. This is a particular benefit for retrofit transformer applications where space may be limited and existing underground service foundations cannot be disturbed. The Promat Durasteel barriers can also be demounted and reinstalled which greatly simplifies the task of transformer replacement.
The barriers are formed from a fibre-cement core sandwiched between mechanically bonded galvanised steel facings. This combines exceptional fire and blast resistant properties with lightness and durability and has led to the barriers being used on many high profile projects including the London Underground Jubilee Line Extension, The British Museum, Heathrow Airport Terminal 5 and the new Westfield London retail project.
