Fire Safety and Environmental Protection
One of the main advantages of dry type transformers is their non-flammable construction. Since they contain no oil, there is no risk of explosion or contamination, aligning perfectly with the principles of eco-friendly and environmentally friendly engineering design.
Reduced Downtime and Maintenance
Dry-type transformers require minimal maintenance, as there are no oil samples to test or leaks to repair. Their reduced downtime leads to higher operational reliability and cost efficiency, especially in data centers and critical infrastructure, where uninterrupted power is crucial.
Energy Efficiency and Smart Monitoring
With the integration of smart sensors and IoT-based control systems, modern dry-type transformers allow real-time monitoring of temperature, load, and insulation health. These features improve energy efficiency, extend operational life, and support smart grid applications.
Competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
Magnetic Core
Made of high-quality, low-loss silicon steel laminations, the core provides a path for the magnetic flux.
01
Windings (Primary & Secondary)
Made from copper or aluminum conductors, these are insulated with high-temperature materials (e.g., Nomex) and are responsible for voltage transformation.
02
Insulation System
The heart of a dry type transformer's durability. It's a combination of solid dielectric materials and air, rated for high temperatures (e.g., Class F or H).
03
Enclosure
A protective steel housing that shields the internal components from dust, moisture, and accidental contact. Its ventilation is crucial for cooling. The degree of protection is defined by an IP rating.
04
Taps
Allow for small adjustments to the turns ratio to compensate for variations in the supply voltage.
05
Commercial Buildings and Public Facilities
Such as hospitals, schools, shopping centers, and office buildings, where safety and environmental requirements are high.
Industrial Manufacturing and Mining
Adapt well to harsh environments with dust and humidity.
Data Centers and IT Facilities
Require quiet and efficient power supply; dry-type transformers are quiet and provide reliable power conversion.
Transportation Facilities
Subway stations, airports, and other high-traffic areas require safe and easy-to-maintain equipment.
Renewable Energy
Wind farms, solar power plants; dry-type transformers align with eco-friendly initiatives.

Each transformer undergoes strict testing procedures in accordance with international standards.
Final Assembly & Packaging
Final assembly ensures mechanical integrity and readiness for transportation and installation.
Test Methods for 10KV Dry Type Transformer
Transformer Turns Ratio Test
You do not need to do a Transformer Turns Ratio (TTR) Test unless you think the system has electrical problems. For instance, if you notice signs of discoloration during your inspection, electrical issues could be at fault, and you would need to do a TTR. For accuracy of this test and safety to your personnel, do not do a TTR test yourself. Instead, contact a professional who has access to the latest testing equipment for this service. An expert will have the tools and protective gear needed to run this test correctly and safely.
Dielectric Absorption Test
For a dielectric absorption test, conduct it for 10 minutes from windings to windings as well as the winding to the ground. This test uses measurements at 10 minutes and one minute and divides them in a ratio, the Polarization Index (PI) ratio. To be acceptable, the PI should be greater than 2.0.
