High voltage. Overhead power lines

   High voltage overhead power lines are those that carry three-phase alternating current at 50 Hz whose rated effective voltage between phases is equal to or greater than 1 kW.

   These overhead power lines need an initial inspection to be legalised. Afterwards, a periodic inspection must be carried out every 3 years.

   Due to the high demand for the creation of high voltage overhead power lines, in OCA Global we have a large expert team in these inspections, following current regulations.
