Dry-type transformer have become a popular choice in many industrial and commercial applications due to their safety, efficiency, and eco-friendly features. Whether you’re installing a new transformer or maintaining an existing one, understanding the proper installation methods, routine care, and environmental benefits is crucial to maximizing performance and lifespan. Let’s dive into the essentials of dry-type transformer management and how they contribute to greener energy solutions.
Introduction to Dry-type Transformer
Dry-type Transformer Equipment operate without the use of insulating oil, relying instead on air cooling and solid insulation materials. This design makes them inherently safer and more environmentally friendly compared to traditional oil-filled transformers. They are widely used in schools, hospitals, factories, and commercial buildings.

Installation Recommendations for Transformer
Proper installation is the backbone of transformer performance. Here are key considerations to keep in mind:
Environmental & Location Factors
Install indoors in a dry, well-ventilated area.
Avoid dusty, humid, or corrosive atmospheres.
Ensure ambient temperature does not exceed 40°C.
Keep away from flammable materials and direct water exposure.
Installation Steps
Pre-Installation Checks: Verify transformer condition upon delivery — check for shipping damage and confirm nameplate specs.
Foundation Prep: Use a level, smooth, reinforced concrete foundation capable of bearing the transformer’s weight.
Positioning: Place the transformer upright with proper clearance (minimum 0.5 m from walls or other equipment) to optimize airflow.
Grounding: Connect a reliable grounding system per safety codes to ensure personnel safety.
Wiring: Follow wiring diagrams carefully and avoid mechanical strain on cables.
Ventilation: Maintain air inlet at the front near the bottom and air outlet at the rear near the top to allow natural airflow.
Installation Aspect
Recommendation
Minimum spacing from walls
0.5 meters
