Product Description
Product Description
The heart of electrical network: high-performance Qinghao transformers!
Qinghao dry type distribution transformer includes cast resin insulation, amorphous alloy and on-load tap changer type, which provides general security for environment with its non-flammable, self-extinguished, toxic gas-free structure and low noise level. Our dry type distribution transformer primary voltage range includes 6,6.3,10.5,11,20,22,24,33, 35,38.5kV and max rating can up to be 3150kVA, which can be manufactured according to customer requirements.
An amorphous alloy dry type distribution transformer is a type of power transformer that uses an amorphous alloy insulating material to withstand high voltage and temperature. The transformer is typically designed for low power applications and is compact in size, making it suitable for installation in limited spaces.

Main Characteristics:
1. High insulation performance: Amorphous alloy is a kind of semiconductor material that has no crystal lattice structure, and its insulating properties are greatly improved compared to traditional materials. The transformer's insulation resistance can reach millions of ohms, which greatly reduces the risk of fire and electrical breakdown.
2. Excellent heat resistance: Amorphous alloy has excellent heat resistance properties, and its insulation performance remains stable at high temperatures. This feature makes the transformer suitable for use in harsh environmental conditions, such as high temperature and high humidity environments.
3. High voltage performance: The transformer's insulation layer is made of amorphous alloy, which has a high degree of non-linearity, making it suitable for high voltage applications. The transformer can withstand high voltage surges and transients, and its electrical insulation performance remains stable even under extreme conditions.
4. Low resistance: The transformer's core and windings are made of low-resistance materials, which reduces the transformer's core loss and winding resistance. This feature improves the transformer's efficiency and reduces energy consumption.
5. Easy maintenance: The transformer's construction is compact and simple, which makes it easy to maintain and replace insulation and core components.
Advantages:
1. High temperature and moisture resistance ability.
2. Advanced structure, compact size, light weight and low partial discharge.
3. High insulation level and equal electric field distribution.
4. Strong heat dissipation, run with 150% rated load under forced air cooling.
5. Fireproof, explosion-proof, pollution-free and low-noise and able to be directly installed in the load center.
6. Easy installation, operation and maintenance.
Applications
Mainly used for infrastructure, public transportation, construction and housing, industry, information technology and new energy power transmission and distribution.
Service environment:
1. Ambient temperature: Maximum +45ºC, Minimum -30ºC
2. Altitude: less than 1000 meters.
