Transformateur sec

Reliable, Safe, and Eco-Friendly Power Distribution Solutions

Dry-type transformers are a cornerstone of safe and efficient power distribution across commercial, industrial, and institutional environments. Unlike their oil-filled counterparts, these transformers utilize air or solid insulation, making them the preferred choice for fire-sensitive or environmentally regulated areas. This collection features a wide range of transformateurs à sec engineered to deliver durability, performance, and long service life under diverse operating conditions.

What Is a Dry-Type Transformer?

A dry-type transformer is a power transformer that uses air cooling and solid insulation (such as epoxy resin) instead of oil or other liquids. It is designed for both medium-voltage and low-voltage applications, commonly used in settings that require low maintenance, une sécurité renforcéeet compact installation.

These transformers are manufactured in line with IEC 60076, IEEE C57.12, and other global standards, ensuring safety, efficiency, and compliance.

Why Choose Dry-Type Transformers?

Dry-type transformers offer several advantages that make them ideal for modern power distribution networks:

• No risk of oil leakage or fire, making them suitable for indoor or underground use

• Eco-friendly and low-maintenance, reducing total ownership costs

• Excellent thermal performance, with options for natural or forced air cooling

• Moisture-resistant insulation—ideal for humid or dusty environments

Major manufacturers like ABB, Schneider Electricet Toshiba recommend dry transformers for data centers, public infrastructure, and clean energy applications due to their high efficiency and compact design.

Dry vs. Oil-Filled Transformers: What's the Difference?

Choosing between dry-type and oil-immersed transformers often depends on application needs. Here's how they compare:

According to Wikipedia and IEEE Xplore, dry-type transformers are increasingly being used in urban networks and renewable energy projects due to these benefits.

Selection Tips: How to Choose the Right Dry Transformer

To find the ideal dry-type transformer for your project, consider:

• Load Profile: Assess power consumption and peak loads.

• Installation Environment: Choose cast resin for harsh, humid environments; VPI for ventilated areas.

• Cooling Requirement: Use AF-cooled types for high-capacity installations.

• Regulatory Compliance: Ensure your selection meets local grid and fire safety codes.

• Space Constraints: Consider the physical footprint, especially in retrofits or basement installations.

If you're unsure, our technical team can help with sizing, technical specs, and compliance documentation.

Frequently Asked Questions (FAQ)
