Product Features
High-Efficiency Magnetic Core
This oil immersed transformer adopts high-permeability grain-oriented cold-rolled silicon steel sheets. It features an innovative full oblique lap laminated core structure, with multi-stage stepped round cross-section core columns and equal-section yoke and core design. This structure effectively reduces magnetic leakage, no-load loss and noise, improving the overall energy efficiency of the three phase transformer.
Optimized Winding Structure
The winding of this 2000kVA electrical transformer adopts corrugated oil duct design and paint-free manufacturing process, fixed with shrink belts for stable and durable structure. All windings are concentric coils. The high-voltage winding is equipped with standard tapping terminals matched with voltage regulation requirements, connected to the top-mounted tap changer. Voltage adjustment can only be carried out after power cut, ensuring safe and reliable voltage regulation operation for the power transformer.
Complete Safety Protection Configuration
Equipped with a standard pressure relief valve as mandatory safety configuration for 30-2000kVA distribution transformer, which can release internal pressure instantly to avoid equipment damage caused by overpressure. Customizable gas relay with alarm and trip terminals is available according to user demands, providing dual safety protection for power system operation.
Accurate Temperature Monitoring System
The top of the transformer tank is reserved with a professional thermometer tube seat, extending 120±10mm into the transformer oil for accurate real-time oil temperature detection. As a 1000-2000kVA high-capacity electric transformer, it is equipped with an outdoor signal thermometer, realizing real-time temperature monitoring and abnormal temperature early warning, adapting to outdoor and harsh industrial operating environments.
Fully Sealed Corrugated Tank Design
The transformer tank is made of high-strength corrugated plates with dust-proof spray coating on the surface, featuring firm paint film, corrosion resistance and dust resistance. The corrugated heat dissipation fins integrate heat dissipation and breathing functions. The elastic deformation of the fins automatically compensates the volume change of transformer oil caused by temperature rise and fall.
Vacuum Oil Injection & Maintenance-Free Performance
Adopts integral vacuum oil injection process to completely remove internal moisture. The fully sealed structure isolates the internal oil system from outside air, effectively avoiding insulation performance degradation and oil aging caused by oxygen and moisture erosion. The three phase transformer realizes long-term stable operation without regular oil sample testing, lowering daily maintenance pressure.
