33kv 0.4kv 1000kva power transformer OLTC
Oil immersed power Transformer:
Our company research and development production of S11 - M series fully enclosed oil-immersed power
transformer has the advantages of low loss, low noise, high efficiency, can obtain good energy saving effect
and reduce pollution. Totally enclosed compared with ordinary oil-immersed transformer, cancelled the oil
storage tank, the oil volume change by corrugated tank elastic corrugated chips to automatically adjust the
compensation, transformer isolated from the rest of the air, to prevent and slow the deterioration of oil and
insulation aging, improve operational reliability, running free maintenance.
Features:
1. The transformer core is made of imported high quality cold rolled silicon steel, which greatly reduces the
no-load loss and no-load current, and the core is bound to ensure the tightness of the core and reduce the noise.
2. The high and low voltage winding is made of anaerobic copper, the low-voltage winding 500KVa and the
following are twin-barrel cylindrical structures, 630KVa and above are foil coils, and the high voltage windings
are made of cylindrical structures.
3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and
improve the quality of power supply.
4. The transformer is fully sealed, extending service life, free of hanging heart and maintenance
5. The measured noise level is below the standard
Conditions of use:
1. Maximum ambient temperature: +40 degrees
2. Minimum ambient temperature: -25 degrees
3. Altitude: <1000m
4. Highest average relative humidity: 90% (20 degrees)
ATTENTION:
1. The payment term: We accept TT,30% deposit and 70% balance paid before goods delivery.
2. The delivery time: Usually it will take about 15-20 days.
3. The standard of package: Usually use strong plywood case for protection.
4. The material of transformer: We have two types, one is with copper and another one is with a
luminum. It depends on your requirement. .
5. The logo: OEM is OK.
