KUCHING: Parts of Sarawak were hit by a blackout on Saturday (July 10) night when the Murum transmission line tripped.
Sarawak Energy Bhd (SEB) said a double circuit tripping of the 275kV Murum transmission line caused a power outage at about 9.30pm.
Major areas affected were Kuching, Sri Aman, Sarikei, Mukah, Sibu, Bintulu and parts of Miri.
