In an effort to live by its slogan “Powering the Nation”, Zesco has set aside US$3.5 million to restructure the Leopards Hill- Coventry 132 KV transmission line to increase electricity capacity.
The project involves the fitting of a Wolf conductor which would include a High temperature Low Sag (HTLS) conductor on the existing transmission line.
This would result in an increase of the transmission capacity in the short to medium term and thereby improve the thermal expansion factor of 86MVA to 170 MVA.
This is according to a statement issued yesterday by the Zesco Public Relations and Marketing Department.
The statement has stated that the uprating of the transmission would be conducted between October 20 and November 10, 2014 from 06:00 hours to 18:00 hours.
However, to carry out this project, there would be increased power interruption which would mainly affect customers in Lusaka’s Chinika Industrial Area, Ndipo, Kanyama, Misisi and John Laing.
“As a result of these works, ZESCO will be switching off the transmission line during the period 20th October to 10th November 2014, from 06:00 hours to 18:00 hours on each outage period, except 23rd to 25th October 2014,” the statement stated.
The HTLS conductor, which has the same physical and mechanical properties as the existing Wolf conductor, will be strung on the existing line using the same tower structures.
Unlike the Wolf conductor, the HTLS conductor is capable of operating at higher temperatures.
At the end of the uprating, it is expected that Zesco customers will be served even better.
