S series type fully sealed oil-immersed transformer is suitable for AC 50Hz, rated working voltage 20kV and below in the power system, as petroleum, metallurgy, chemical industry, textile, light industry and other enterprises and dusty places of the distribution transformer.
Cde Dsign
1.High-efficiency core structure
Adopting high permeability grain oriented cold rolled silicon steel sheet, full oblique seam stacking process, the core column is multi-stage stepped circular cross-section, uniform magnetic circuit, low no-load loss.
2. Strong heat dissipation winding process
The winding adopts corrugated oil channel + tight tape tying, non-impregnated paint process, high heat dissipation efficiency; concentric coil design, high-voltage winding is equipped with power-off adjustable tap changer, safe operation.
3. Fully sealed tank system
Corrugated oil tank structure: both heat dissipation and "breathing" compensation function, vacuum oil injection process to eliminate moisture intrusion, no oil storage cabinet design, maintenance-free, anti-oil aging.
Security And Monitoring
1. Multiple safety protection: 30~2500kVA standard with pressure relief valve, optional gas relay (with alarm/trip function).
2. Intelligent temperature control: The whole system is equipped with oil-immersed glass thermometer as standard, and 1000~2000kVA is equipped with outdoor signal thermometer to monitor the oil temperature in real time.
Advantageous Highlights
1. Long life and low maintenance: Fully sealed anti-oxidation design, no need for regular oil sample testing.
2. Compact and reliable: Corrugated tank surface powder coating, corrosion resistance and solid structure.
3. Safety upgrade: Tap changer power-off operation + multiple protection devices to eliminate operational risks.
