Construction of a MV Power Line
For a 3MW solar power plant
Pole Installation
measuring heading and verticality
Pole installation observing inclination and heading guidelines to obtain the predefined design measurements.
Underground Lines
Two underground connections were required
The connection to PCS and a line corossing requiered underground connections. These required cable splices, wich were performed in a wind shelter to ensure a clean installation.
Team Coordination
Safety and procedures
The team met regularly to review safety measures and installation procedures to comply with the engineering guidelines and code requirements.
Line Crossing
66kV line undercrossing
A guard line was used complying with the local distribution network standard.
Cable Tensioning
Following engineering temperature tables
Cable tensioning was performed measuring the cable temperature and refering that to the calbe tensionong tables specified in the engineering proceedings. These tensions were calculated to ensure safety margin levels and pole solicitation within the allowed limits.
Reconnector and Metering at the Connection Point
With aux transformes and communications
The connection point system considered protections, Metering system, aux transformer and comunications.
