Transformers for Data Centre

Solutions for maximum operational levels and energy efficiency

A data center is an organizational unit that coordinates and manages either devices and services for data management or the IT infrastructure for one or more companies.

It is the technological core of the company, as it guarantees the continuous functioning of all processes, systems, communications and services, and supports the daily operations of a company and its efficiency.

At this point in history, where information systems are an important tool for any business, data centers have become the protagonists for phenomenal growth. IOT, artificial intelligence, data analytics and cloud storage are just some of the key drivers of this evolution.

Reliable, efficient and high-quality products and solutions are needed to support this development.

Cast resin transformer with H-ART technology

This solution is for a distribution transformer with a nominal power rating of 2.5MVA and a primary voltage of 20kV.

It is a solution based on customer special requirements and installed in a building where a high level of electrical noise is present in the load due to not linear electronic switching devices, air conditioning etc.

This dry-type transformer is suitable for this high level of harmonics (equivalent to K-factor 13); it has Class H insulation, electrostatic screen and it is cooled without the needs of forced cooling.

Installation is indoor in a dedicated IP21 enclosure.

On secondary windings are installed Current Transformers on each phase for measuring purpose wired to a dedicated junction box.

  • Power Rating: 2500kVA
  • Insulation Temperature Class: H-ART180
  • Compact design
  • K13 harmonic profile
  • Electrostatic screen
