ACB Retrofits – UK Brewery

This project at a UK brewery required the existing 30 year old ACB to be replaced due to unreliability

The contract had been awarded to a major UK switchgear manufacturer who recognised our expertise in this area so they were more than happy to sub-contract it to ExEllison.

The old ACBs had asbestos arc-chutes as is common on many Air Circuit Breakers of this age and is reason enough to change the ACBs as well as the lack of spare parts and expertise to keep them in good working order.

The ExEllison installation team is fully trained for the removal and transportation of Asbestos and provide a traceable disposal certificate for the material removed.

The Customer had originally been told that a week-long shut-down would be required.

However, the unique ExEllison design allows an easy-fitting retrofit assembly to be completely constructed and tested in our works removing the need to make any parts on site.

3 – ACBs were retrofitted and two bus-section ACBs removed and shorting-lings fitted – all in a single day.

ExEllison have retrofitted over 400 ACBs of various types including:

  • Ellison
  • Ottermil
  • ABB, Mitsubishi
  • Terasaki
  • Siemens
  • Reyrolle
  • Schneider
  • Merlin Gerin
  • Johnson Philips
  • GEC
  • Whipp & Bourne
  • STS Switchgear
  • Dorman Smith
  • Eaton, Proteus
  • AF Switchgear
