Schneider Substations: Feature, Benefits, and Applications

The electricity demand is growing at an unprecedented speed that can only be fulfilled by power-generating substations. Based on resource availability, different types of substations are available – thermal, atomic, and hydro-electric. They are built at different locations that are not necessarily close to the load centers where the actual power utilization can be done.

Electricity generated is in low-voltage levels; however, it is economical to supply power at high-level voltage. Several switching and transformer stations are required for preserving both levels of voltage.

What is the Substation?

A substation is an electrical system with a high-voltage capacity that can be used to control the apparatus, generators, electrical circuits, and similar other equipment. They are primarily used to convert alternative current (AC) to direct current (DC).

Some of its types of small in size consisting of an in-built transformer and relative switches. While other substations are significantly large, requiring various types of transformers, multiple equipment, circuit breakers, and switches.

Various types of substations are:

  • Step-up substation
  • Step-down transformer substation
  • Distribution substation
  • Underground distribution
  • System station
  • Customer substation
  • Switchyard

What is the Distribution Substation?

The distribution type substation is placed near the main power where it is stepped-down to supply voltage to the consumers by using a proper dispersal network.

This type of substation typically operates at 2.4 to 34.5 kV voltage levels and generally deliver electricity directly to industrial and residential customers. These feeders serve a significantly large number of premises and usually contain various branches.

For medium and low voltage, prefabricated substations are also used. For crowded places where it is challenging to place open distribution substations, it becomes crucial to install a compact and closed substation structure. Especially, Metaclad Distribution Substations become efficiently beneficial in such a case.

Metaclad Distribution Substation

It is a medium voltage transformer that operates between 200kVA to 1500kVA (110000/433V). Compact in size than traditional substations, the Metaclad Distribution substation by Schneider Electric is rated 200, 315, 800, or 1000kVA.

It has a ringmaster range switchgear that consists of a ring main unit, circuit breaker, or switch disconnector.


  • Free-breathing or hermetically sealed transformer
  • Option between dielectric fluids (mineral oil or Midel 7131 fluid)
  • Ringmaster range switchgear
  • RMU, circuit breaker, or switch disconnector
  • Up to seven low voltage fuse ways or MCCB/ACB options
  • Stainless steel enclosures, powder-coated in a variety of colours
  • Ease of installation with complete access to all components


  • Easy specification

Single point of contact for entire substation

  • Choice

Metaclad distribution substation is available in rating from 200kVA to 1500kVA, along with voltage up to 11kV.

  • Small footprint

Due to its small and compact equipment size, it can be used anywhere.

  • Reduced downtime

Less time required for its installation on-site

  • Safe

21kA KEMA certified expulsion vent is used with MV switchgear that provides operator safety.


Various applications of this compact substation are found in energy. Infrastructure and commercial industries that have high-voltage requirements.

  • Airports

This substation is an ideal solution for distribution from the airport’s 11kV network.

  • Retail parks

It is an excellent means of supplying shop units from the local distribution system.

  • Factories

The power supply for a factory can be installed quickly and easily using the Metaclad Distribution Substation.

  • Housing estates

This type of substation is a quick and easy way of completing the electrical installation of a large housing estate, where vandal resistance is a concern.

  • Other sectors

Other sectors where this substation has applications are pharmaceuticals, educational establishments, industrial refurbishment, petroleum, and sports facilities.

Installing a substation at premises that require heavy-voltage can be a wise decision. Taking help from specialized electric distributors of the area becomes a wise decision. They can help in selecting the best distribution substation as per your requirement.
