Withdrawal of Surge Arresters from Approved Materials List

What is Happening?

In the most recent update to the Standard Contestable (Approved) Material List CEOM7004, a number of items have been removed. CLAH (Current Limiting Arcing Horns) surge arresters have been discontinued by the manufacturer and following a review of their requirement, CLAH surge arresters are to be withdrawn from Essential Energy Covered Conductor Thick (CCT) constructions.

Other associated equipment used in conjunction with CLAH surge arresters will also be withdrawn. The CCT construction drawings in Section CEOM7303 of the Overhead Construction Manual have been updated to reflect the changes.

The Standard Contestable (Approved) Material List CEOM7004 has also been updated and the associated material has been removed. For all other updates please make yourself familiar with Issue 55 of the AML.

What do you need to do?

  1. Review the above construction drawings and the AML on the Document Library.
  2. Communicate this information to relevant members of your organisation.
