3 Phase Step Down Voltage Transformer 35kva 50kva 75kva 350kva 20kv to 0.4kv Dry Type Isolation Power Transformer

As an important power equipment, dry-type transformers have been widely used in many fields due to their unique advantages. Compared with traditional oil-immersed transformers, dry-type transformers use air or other gases as insulating media and do not require flammable transformer oil, so they are safer and more environmentally friendly. This feature makes them particularly suitable for places with strict fire protection requirements, such as high-rise buildings, underground facilities, airports, hospitals, data centers and other important public facilities.

Dry Type Transformer

application Details

Dry-type transformer is a high-voltage power distribution equipment that uses solid insulation (such as epoxy resin) instead of traditional transformer oil. It has the advantages of fire prevention, explosion prevention, environmental protection, and low loss. It is suitable for power systems in industry, commerce, new energy and special environments.
Rated voltage: 20kV (or 22kV) high voltage side, 400V/690V low voltage side
Capacity range: usually 100kVA~5000kVA, larger capacity can be customized
Short circuit impedance: 6%~8% (standard value, adjustable according to demand)
Temperature rise limit: ≤100K (F class insulation) or ≤125K (H class insulation)
Noise level: ≤55dB (natural cooling) or ≤65dB (forced air cooling)
technical parameter
20kv to 0.4kv Dry Type Isolation Power Transformer

 

Application areas



Industrial power distribution: suitable for heavy industrial environments such as chemical plants, metallurgy, and mining, resistant to dust and corrosion.
Commercial buildings: used in places with strict fire protection requirements such as high-rise office buildings, shopping malls, and hospitals.
New energy power generation: photovoltaic power stations, wind farm boost or grid-connected transformers.
Railway transportation: subway and high-speed rail traction power supply systems, adapting to frequent start-stop and impact loads.
Data center: Provides stable power for server rooms, low loss, and high reliability.


Selection and customization



Users can customize according to their needs: sales@gneesteels.com, choose different winding materials (copper/aluminum), cooling methods, protection levels and intelligent monitoring functions (such as temperature control, remote monitoring, etc.).
