Dry Type Transformers

Dry Type Transformers: A Reliable Power Solution

Dry Type Transformers are electrical transformers that use air or solid insulation instead of oil for cooling and dielectric support. This design makes them especially safe, low-maintenance, and environmentally friendly.

GANELEC supplies the transformer industry with YAWEI Dry Type Transformers including in-country backup, service and warranty.

All orders can be made to the customer's specifications. 

What Are They Used For?

1. Indoor installations in hospitals, schools, office buildings, shopping malls, and other fire-sensitive areas — no oil means zero risk of leaks or fire.
2. Commercial, data‑center, and telecom power distribution, where compact size, quiet operation, and minimal maintenance are essential.
3. Industrial sites, especially those handling flammable materials (chemical, petrochemical, oil & gas), to minimise environmental and fire risks.
4. Renewable‑energy applications such as wind farms and solar plants, where oil‑free equipment aligns with sustainability goals.
5. Public infrastructure — airports, rail systems, tunnels, metro stations — safe, robust, and code-compliant equipment.

Key Advantages

• No oil — no fire leaks: Totally eliminates flammable or toxic insulation like mineral oil.
• Minimal maintenance: No oil testing or replacement needed; simpler inspection routines.
• Compact installation: Can be placed close to loads without special vaults or containment measures.
• Robust safety features: High mechanical strength, self-extinguishing insulation, and seismic resistance.
• Better overload tolerance: Effective heat dissipation allows handling of temporary overloads better than oil-filled types.
• Environmentally sound: Oil-free, pollutant-free, and no greenhouse gas emissions.

Safety and Eco-Friendliness of Dry Type Transformers

Dry Type Transformers are designed with safety in mind, featuring self-extinguishing and low fire hazard properties. Constructed with eco-friendly insulation materials, these transformers not only provide reliable performance but also ensure peace of mind in your operations.

Due to their flame-retardant design, Dry Type Transformers significantly reduce the risk of fire, allowing you to operate without the constant worry of investing in additional fire suppression measures. Even when faced with arcing, they do not produce toxic gases, making them an ideal choice for environments where safety is paramount.

With easy maintenance and a commitment to protecting both the environment and your facility, Dry Type Transformers stand out as a responsible and efficient power solution.

Zero Oil Usage: A Cost-Effective Solution

One of the standout features of Dry Type Transformers is their zero oil usage. Unlike traditional transformers that rely on liquid for cooling, Dry Type Transformers utilize air to maintain optimal operating temperatures. This innovation eliminates the need for costly oil purchases and reduces associated maintenance expenses.

With no liquid to manage, you can enjoy a virtually maintenance-free experience, allowing you to operate worry-free. The absence of oil not only simplifies upkeep but also enhances safety, as there's no risk of leaks or spills. Choose Dry Type Transformers for a reliable, economical solution that prioritizes efficiency and peace of mind.

Eco-Friendly and Safe

Dry Type Transformers stand out as a green alternative in the power distribution landscape, as they do not use oil or any liquids in their operation. This means you’ll never have to worry about oil leaks or other environmental pollutants, contributing to a cleaner, safer environment.

Additionally, these transformers have a self-extinguishing feature, significantly reducing the risk of explosions. Their robust design allows them to withstand unexpected weather changes, making them ideal for operation in heavily polluted or challenging environments.

By choosing Dry Type Transformers, you're opting for a solution that prioritizes not only safety and performance but also environmental responsibility. Enjoy the peace of mind that comes from utilizing technology designed with both the planet and your operational needs in mind.

Low Cost Installation and Lower Load Losses

Dry Type Transformers offer a cost-effective installation process due to their inherently low-risk nature. There are minimal restrictions during installation, eliminating the need for extensive environmental precautions, such as groundwater protection. This not only simplifies the setup but also reduces overall installation costs.

What’s more, these transformers are built to last, with a lifespan that can exceed 20 years and a low likelihood of failure. Their efficient design results in lower load losses, ensuring that more of the energy consumed is effectively utilized, enhancing your operational efficiency.

By choosing a Dry Type Transformer, you not only minimise installation expenses but also invest in a reliable, long-lasting power solution that supports your operational goals while maintaining cost efficiency.

Low Maintenance

Once installed, these transformers require minimal upkeep, allowing you to focus on other important operational aspects. With air as their primary cooling medium, there’s no risk of dirt buildup, and you won’t need to manage liquid levels or perform regular liquid testing.

While routine inspections by an expert are recommended to ensure optimal performance, these are straightforward and hassle-free. Overall, Dry Type Transformers provide a reliable, low-maintenance solution that supports your operational efficiency while giving you peace of mind.

Sustainable

Choosing a Dry Type Transformer means you're making a significant contribution to conserving our planet’s resources. These transformers are designed for efficiency, featuring low electricity usage that reduces your overall energy consumption.

Additionally, Dry Type Transformers are constructed from 90% recyclable materials, promoting a circular economy and minimizing waste. With a reliable service life of over 20 years, they provide long-lasting performance that further supports sustainability efforts.

By opting for a Dry Type Transformer, you are actively participating in environmental stewardship while enjoying an efficient and effective power solution.
