15kv fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution.Fully sealed transformer and ordinary oil-immersed transformer, the elimination of the oil tank, the change of oil volume by the elastic corrugated tank to automatically adjust compensation, transformer and air isolation, prevent and slow down the deterioration of oil and insulation aging, enhance the reliability of operation, normal operation without maintenance. 1. Standards: GB, IEC, GOST, EN, NF, ANSI/IEEE (customizable according to customer standards) 2. Certification: ISO、CE、IEC、SABS、COC、CSA、UL 3. Efficiency: The efficiency of an 15kV three-phase oil immersed transformer can exceed 99%, which can meet the European 2015/2014/548/EC ecodesign Tier 2 energy efficiency regulations. 4. Maintenance free: IP65 protection level, dustproof and moisture-proof, maintenance free, designed for a lifespan of over 25 years. 5. Environmental protection and sustainable development: FR3 vegetable oil can be selected. 6. Overload capacity: Copper coil 15kv transformer allows short-term overload to 150% of rated capacity for no more than 2 hours, but requires monitoring of oil temperature (≤ 95 ℃).
- Input voltage: 15kV
- Output voltage: 0.4kv 0.415kv 0.420kv
- Capacity: 30-5000 kva
- Frequency: 50 hz
- Remark: voltage, capacity, frequency, connection group and loss can be customized according to customer requirements
The transformer core is made of imported high-quality cold-rolled silicon steel sheets, which can greatly reduce the no-load loss and no-load current, and tie the core to ensure the compacting degree of the core and reduce noise.
The high-low voltage winding is made of oxygen-free copper, and the low-voltage winding of 500kVA and below adopts double-layer cylindrical structure.The 630kVA and above adopts double or four helix structure, and the high-voltage winding adopts multi-layer cylindrical structure.
The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the power supply quality.
The transformer is a fully sealed structure, the inner and outer surface of three primers, one coat of finish coating, the product has anti-salt fog, anti-heat and humidity, anti-mold, beautiful and durable, enhance the reliability of operation
The measured noise value is lower than the industry standard.After normal transportation, this series of transformers can be installed without the need for core inspection, and can be put into operation after passing the acceptance test.
*Voltage conversion of urban distribution network (15kV → 400V);
*Power distribution in industrial plants such as mines and petrochemicals;
*Grid connection of renewable energy power plants (such as wind farms);
*Hospitals, data centers, and other places that require high reliability power supply.
The common capacity ranges from 25kVA to 10MVA, with the 100kVA to 2000kVA models of 15kV/400V being the most widely used, depending on the load requirements.
