Medium Voltage Transformers

A transformer or electrical transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.


What is a Medium Voltage Transformer?


Medium voltage transformer, also known as MV transformer, is the equipment used in the electrical power distribution system to provide final voltage transformation by stepping down to lower voltage levels suitable for utilization by industrial, commercial, and residential facilities.


These transformers are important to efficient and safe transmission of electrical power across various applications, including industrial plants, utility substations, and renewable energy installations. By stepping down the voltage for local distribution, medium voltage transformers enable the safe and reliable supply of electricity to end-users while minimizing energy losses during transmission. In addition to voltage regulation, medium voltage transformers also provide isolation and protection functions, ensuring the stability and integrity of the electrical distribution network.


Discover our medium voltage transformers that ranges from dry-type, oil and power transformers from medium voltage up to 170kV. Our long experience with all types of electrical transformers translates into reliable products for any application, while our new Trihal IoT connected features allow you to take a step forward in efficiency. The digital transformation of MV transformers is helping eradicate a list of worries faced by medium voltage appliances. To understand this simply, it provides the operations teams a greater level of transparency in terms of their MV assets on a regular basis. By collating data-driven information regarding equipment conditions, the workforce or project managers can take swift and proactive measures as opposed to reactive measures in terms of negating unforeseen problems, which helps in lowering downtime. This helps promote the concept of predictive maintenance, which helps avoid failures, as well as keeping maintenance requirements and costs at an all-time low.

Our Dry-Type Distribution Transformers offer high levels of reliability and safety. With low flammability, they are ideally suited for critical applications. Best-in-class cast resin transformers are engineered to maximise your investment through reliable performance and a long service life.

  • Dry-Type Distribution Transformers are essential components in electrical power distribution, offering an alternative to traditional oil-filled transformers by using air or gas for insulation.
  • Filled with sustainable design, solid, and resin-based insulation materials, the absence of oil reduces the environmental impact making them more reliable, less prone to fire hazards, and suitable for indoor installations and areas where environmental safety is a concern.
  • Low maintenance: with no oil to manage, Dry-Type Transformers require minimal maintenance, reducing operational costs over time.
  • Compact design: suitable for installations with limited space, such as urban and industrial settings.


What are the types of Dry-Type Transformer?

  • Cast Resin Transformers (CRT): use epoxy resin to insulate the windings, providing high mechanical strength and moisture resistance.
  • Vacuum Pressure Impregnated (VPI) Transformers: use a vacuum and pressure process to impregnate the windings with resin, offering enhanced insulation and protection against environmental factors.


How is digital transformation improving Medium Voltage Transformers?

The digital transformation of Medium Voltage Transformers is helping to provide operations teams with a greater level of data-driven insight into equipment conditions. It enables proactive measures, helping to lower downtime, promote predictive maintenance, and keep maintenance requirements and costs at an all-time low.


Where are Dry-Type Transformers widely used?

  • Commercial buildings: for lighting and power distribution in office buildings, malls, and hospitals.
  • Industrial facilities: powering machinery and processes in factories and plants.
  • Data centres: providing reliable power with minimal risk of fire.
  • Renewable energy projects: supporting solar and wind energy installations where safety and environmental considerations are critical.
