Substations

The company specializes in electrical Medium Voltage Projects. Our experience and expertise in the energy sector allow us to provide full technical support in the life circle (installation, start up, maintenance) of medium voltage substations in industries, hospitals, buildings and hotels.

The steps of installation of MV substation are the selection of

  • Power transformers (dry type or oil)
  • Medium Voltage Cable
  • Medium voltage Cell,
  • Electrical equipment of medium and low voltage
  • Equipment and instruments of control switchgear and circuit breakers

A preventive maintenance involves the following steps:

  • Trip levels and accuracy of relays and low, medium and high voltage circuit breakers
  • Burnishing and adjusting contacts
  • Lubricating moving parts
  • Measure of dielectric Absorption of the oil
  • Insulation resistance test (winding-to-winding & winding-to-ground)
  • Retrofitting trip units
  • Cleaning cubicles
  • Visual inspection and replenish of silical gel
  • More visual inspections
  • Increasing the reliability and the performance of the transformer
  • It can identify and prevent potential problems
  • A preventive maintenace in regular basis can low the seervive costs 
  • Increase the longevity of the transfomer
