Product Description

Key Features

Oil-Free Design

The core and windings are not immersed in insulating oil, eliminating the risks of fire, explosion, and oil contamination, allowing direct installation near the load center.

Cooling Method

Utilizes natural air cooling (AN) or forced air cooling (AF). AF mode can increase capacity for demanding loads.

Eco-Friendly & Safe

Excellent flame-retardant and self-extinguishing properties. Suitable for locations with strict environmental and safety requirements.

Low Maintenance

Minimal maintenance required; units can be equipped with comprehensive temperature monitoring and protection systems.

Environmental Conditions

Temperature & Humidity: -45°C to +40°C, relative humidity <70%.
Altitude: Not exceeding 2500 meters.
Placement: Avoid rain, moisture, high heat, or direct sunlight. Maintain at least 40cm ventilation clearance.
Chemical Safety: Prevent operation in environments with corrosive liquids, gases, dust, or metal shavings.
Interference: Prevent operation in environments with heavy vibration or electromagnetic interference.
Logistics: Avoid long-term inverted storage and strong impacts during transportation.

Typical Applications

Public Infrastructure

High-rise buildings, commercial centers, hospitals, airports, docks, and subways.

Industrial & Specialized

Factory workshops, local lighting, museums, tunnels, and specialized laboratories.

Frequently Asked Questions

Q: What is a dry type transformer and how does it differ from oil-filled units?

A dry type transformer uses air as the cooling medium instead of insulating oil. It eliminates risks of fire, explosion, and oil leakage, making it safer for indoor or environmentally sensitive installations.

Q: What cooling methods are available?

It supports natural air cooling (AN) and forced air cooling (AF). AF mode uses fans to enhance airflow, increasing the transformer's rated capacity compared to AN mode.

Q: What are the recommended installation conditions?

Ideal conditions include temperatures between -45°C and +40°C, humidity below 70%, and altitudes under 2500m. Keep away from direct sunlight, corrosive substances, and vibration.

Q: How much maintenance is required?

Maintenance is minimal compared to oil-filled units. Most units come with temperature monitoring systems to ensure safe operation with very little manual intervention.

Q: Where are these transformers typically used?

Commonly used in high-rise buildings, hospitals, airports, subways, and places with strict fire or environmental codes like museums and tunnels.

Q: Is it safe for fire-sensitive environments?

Yes. Dry type transformers feature flame-retardant and self-extinguishing properties, making them the preferred choice for underground facilities and high-density residential areas.
