Line collapse: Moses Hlophe-Helehele 132kV Line restoration

During a storm event on Thursday 14 November, 2019 extreme winds hit the area just east of Manzini in South Africa.

The windstorm hit the Moses Hlophe-Helehele 132kV line approximately five towers away from Helehele Substation.

Three suspension towers of type ‘255 A’ collapsed when the wind hit the line. The towers collapsed transversally and there was no evidence of broken conductor. Between towers 42 and 43, the HV conductors landed on an under-crossing 11kV line, which was also damaged.
