Product and Services

Oil Immersed Transormer
liquid-immersed transformers are engineered to meet the evolving demands of modern power networks. They enable the integration of renewable energy, support grid modernization, and deliver long-term efficiency with minimal environmental impact.

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

Mining transformers
Varelen transformers are engineered with robust to withstand dust, moisture, and extreme temperatures, delivering reliable performance even in the toughest mining environments.

VPI Dry Type Transformer
dry-type Vacuum Pressure Impregnated (VPI) transformer is widely relied upon for its long, reliable service life in harsh industrial applications.

Green Hydrogen Transformer
Hydrogen can be produced through an electrolyser, a device that uses electricity to split water into hydrogen and oxygen through a process called electrolysis. This process requires a power source, typically in the form of alternating current (AC), to provide the energy needed for the electrolysis reaction.

Compact Substation
Our box-type substation offers a safe, space-saving, and cost-effective energy distribution solution, featuring integrated components for efficient electrical transformation and protection. Easy to install and secure.

Frequently Asked Questions
Dry-type transformer uses solid insulation instead of oil, making it safe, eco-friendly, and low-maintenance – ideal for indoor and environmentally sensitive areas.
Fluid-immersed distribution transformer is an oil- or ester-filled transformer that converts higher medium-voltage levels down to lower voltages, typically up to 36 kV on the primary side and 250–800 V on the secondary side, while maintaining the same frequency.
All distribution transformers are tested according to international standards, and Varelen monitors and complies with regulations like the European Eco Design Directive and US DOE rules, adapting designs as requirements evolve.
