Product Overview
This 2000–20000kVA/35kV oil‑immersed power transformer is purpose‑built for ultra‑high power consumption scenarios with extreme load demands and rigorous stability requirements. Engineered as a heavy‑duty power distribution core unit, it is specially designed to cope with intensive power consumption, frequent load changes and harsh operating conditions, providing a secure, stable and high‑capacity power supply solution for large industrial plants, heavy‑production facilities, energy hubs and other high‑load power nodes.
1. Real-Time Automatic Voltage Regulation (Core Competitive Advantage)
The transformer's defining strength is its intelligent automatic voltage regulation system, which completely solves the pain point of grid voltage fluctuation and instability. Without manual intervention, it conducts real‑time dynamic adjustment according to changes in grid voltage and load power, accurately locking the output power within a precision range of ±10%. This ensures that the terminal power supply remains consistently stable, even when the external power grid suffers voltage deviations or disturbances.
2. Outstanding Stability Against Sudden Load Surges
In the face of abrupt, large‑scale increases in power consumption or instantaneous heavy load shocks, the transformer still maintains smooth, uninterrupted and reliable operation with no performance decay, voltage collapse or operational faults. Its strong load‑bearing capacity and anti‑fluctuation performance effectively avoid production halts, electrical equipment damage or power supply failures caused by unstable voltage, delivering a continuous and trustworthy power guarantee for long‑term heavy‑duty working conditions.
Technical Features
● Wide capacity coverage: 2000kVA to 20000kVA, fully matching 35kV high‑voltage heavy‑load power systems
● Built‑in automatic voltage regulation (AVR) module for real‑time adaptive adjustment and high response speed
● Precise power output control within ±10% to maintain constant voltage stability under complex working conditions
● Excellent overload resistance and strong tolerance to sudden load increases
● Oil‑immersed heat dissipation structure for efficient cooling under continuous high‑power operation
● High mechanical strength and reliable insulation system to adapt to harsh heavy‑load environments
● Stable long‑term operation with low failure rate, minimizing downtime for critical power applications
Type And Meaning
Product Features
Flexible voltage regulation
The transformer has a voltage regulation capability of ±2×2.5% or ±5%, and the OLTC (on-load voltage regulator) response time is ≤20ms, which can achieve uninterrupted and seamless voltage regulation.
Excellent electrical performance
The high-voltage winding of this oil-immersed transformer uses oxygen-free copper wire and undergoes special surface treatment to ensure smoothness and no defects, significantly reducing load losses and improving electrical reliability.
Tightly sealed
Our transformer oil tank is a fully sealed structure, and the corrugated wall can automatically expand and contract with the change of oil temperature, effectively preventing oil aging and internal moisture.
