Package & Unit Substation are all factory assembled and tested. They are designed and manufactured in order to satisfy the customer’s specific requirements. There design engenders a high level of flexibility that covers a wide range of applications. The package & unit substation is a combination of the Ring Main unit, The Transformer and The Low-Voltage panel.

A unit substation is a combination of a Transformer and a Low Voltage panel. These substations are used for effective electrical power distribution in medium voltage to low voltage distribution systems.

Substations may be described by their voltage class, their applications within the power system, the method used to insulate most connections, and by the style and materials of the structures used.

Substation transfers power from the transmission system to the distribution system of an area. It is uneconomical to directly connect electricity consumers to the main transmission network, unless they use large amounts of power, so the distribution station reduces voltage to a level suitable for local distribution.

  • integrating SF6 insulated Ring main units with various configurations
  • integrating oil or dry type Transformers
  • integrating metering and protection
  • High operation reliability
  • Operating personnel safety
  • That they are suitable for building, infrastructure and industry.
  • All interconnecting equipment between medium voltage, transformers and low voltage are factory tested.
