Western Power has advised that crews will be washing ash and dust off the power lines in Bullsbrook from helicopters on Friday.

A Western Power spokesman said as there were many horse breeders and livestock holders in the area they advised owners to move animals from paddocks near power lines.

Western Power has started rebuilding parts of the electricity was destroyed by the Bullsbrook bushfire after the Department of Fire and Emergency Services allowed crews access to sections of the bushfire zone.

Western Power’s field operations head Brad Lacey said to restore the network they had to replace more than 180 power poles and 2km of power lines.

“Western Power crews will be working hard for at least a week to safely rebuild the network and help the Bullsbrook community return to normal as quickly as possible,’’ he said.

“Yesterday we were granted access to safe areas of the fire zone, but we anticipate that Western Power will be given the all-clear tomorrow, which will allow more than 35 crews to join the restoration efforts.

Western Power advises anyone returning to the fire zone to stay safe and if they see a fallen powerline or damaged equipment, stay well clear and call to its 24/7 emergency line on 13 13 51.

On Tuesday 59 customers were still without power due to the bushfire.
