Product Features
● Oil free design, fire and explosion prevention: does not use flammable transformer oil, suitable for places with strict fire prevention requirements (such as underground substations and commercial centers).
● Environmental safety: No oil leakage risk, no pollution, in compliance with green electricity standards.
● Maintenance free: No need to monitor oil level or quality, reducing operation and maintenance costs.
● Good heat dissipation performance: using forced air cooling (AN/AF) or natural cooling (AN), stable temperature rise control.
● Strong adaptability: It can operate in high humidity, high altitude, and polluted environments (requiring special protective treatment).
● Flexible installation: With a relatively small volume, it can be installed close to the load center to reduce line losses.
Applications
Urban distribution network: box type substations, ring main unit matching.
High rise buildings: commercial centers, hotels, hospitals (with high fire safety requirements).
Rail transit: subway, high-speed railway substation (explosion-proof, low-noise).
Industrial fields: chemical industry, mining (anti-corrosion, moisture-proof).
New energy: photovoltaic and wind power boosting stations (suitable for harsh environments).


Advantages
Dry type substation transformers have significant advantages in safety, environmental protection, and installation flexibility due to their unique oil-free design and solid insulation structure, making them particularly suitable for places with high requirements for fire prevention, space, and maintenance. Here are its main advantages:
1. High safety, fire and explosion prevention
No flammable liquids: Do not use transformer oil to avoid the risk of oil leakage, combustion, or explosion. Suitable for high-rise buildings, subways, hospitals, data centers, and other places with strict fire prevention requirements.
Flame retardant insulation material: Made of high temperature resistant materials such as epoxy resin, with high insulation level (such as H-grade, 180 ℃), it is not easy to burn even if short circuited.
Suitable for dense areas: can be installed in enclosed spaces such as basements, commercial centers, tunnels, etc., without the need for additional fire prevention measures (such as oil pits).
2. Environmentally friendly and pollution-free
No oil leakage risk: Traditional oil immersed transformers may contaminate soil or water sources due to oil leakage, while dry-type transformers are completely oil-free and comply with green power standards.
Harmful gases: does not produce SF6 (sulfur hexafluoride, strong greenhouse gas), some models use environmentally friendly gases (such as dry air, nitrogen) for insulation.
Recycling: Epoxy resin and other materials can be degraded or recycled to reduce electronic waste pollution.
3. Maintenance free, low operation and maintenance costs
No need for oil monitoring: eliminates maintenance work such as oil level inspection, oil quality testing, and oil filtration, reducing long-term operation and maintenance costs.
Anti pollution and moisture-proof: The epoxy resin encapsulated winding can resist moisture, dust, salt spray, and is suitable for harsh environments such as chemical and coastal areas.
Long lifespan: High quality transformers can have a lifespan of 20-30 years (such as the SCB10/CB13 series), and have a low failure rate.
4. Flexible installation and space saving
Compact size: Compared to oil immersed transformers, dry-type transformers are smaller in size and lighter in weight, making them suitable for indoor and box type substations with limited space.
No need for oil tanks and firewalls: directly installed in the distribution room to reduce civil engineering costs (oil immersed fire isolation facilities are required).
Suitable for various environments: It can operate in a wide temperature range of -25 ℃~+40 ℃, and some models support high altitudes (above 4000m).
5. Efficient and energy-saving, low loss
Low no-load loss: Using high-quality silicon steel sheets and foil windings, the no-load loss is 10%~20% lower than that of oil immersed type (such as SCB13 dry transformer, which meets the national energy efficiency level 1).
Intelligent temperature control: equipped with forced air cooling (AF) or intelligent temperature control system, with overload capacity increased by 30%~50%, suitable for short-term peak loads.
6. Low noise, suitable for urban environments
Silent operation: No oil pump, no oil flow noise, only slight sound when the fan is running (<65dB), suitable for hospitals, schools, and residential areas.
Low vibration: The mechanical structure is stable, reducing the impact of vibration on the building.
10-15 dB compared to oil immersed type, suitable for office areas and residential areas.
