Key Advantages: The Strength of Oil-Immersed Isolation Technology

1. Advanced Isolation: Safeguarding Equipment and Personnel

At the heart of this transformer is its exceptional isolation capability, made possible by a precision electromagnetic design that creates a complete electrical barrier between input and output circuits. This addresses three critical pain points in power systems:

Grid Interference Suppression: It blocks harmful harmonics, surges, and voltage spikes from the grid, delivering "clean power" to precision equipment like CNC machines, medical devices, and data servers. This reduces equipment failures and data loss caused by unstable power, minimizing costly downtime.
Personnel Safety: In cases where the grid’s neutral grounding is inadequate, the isolation design breaks the ground loop if leakage occurs on the load side, significantly lowering the risk of electric shock for on-site personnel.
System Segmentation: It prevents cross-interference and fault transmission between separate circuit systems (e.g., a factory’s production line and office infrastructure), boosting the overall stability of the power network.

2. Oil-Immersed Cooling: Efficiency and Longevity Combined
Winley Electric’s decades of expertise in oil-immersed technology shine through in this transformer, offering advantages that set it apart from dry-type alternatives:

Superior Heat Dissipation: High-quality transformer oil has a thermal conductivity far greater than air, quickly transferring heat from the core and windings to the outer shell. This reduces operational losses, improves energy efficiency, and ensures compliance with national energy-saving standards.
Strong Overload Resistance: During short-term load peaks, the transformer oil absorbs excess heat, protecting windings from overheating and damage. This durability extends the transformer’s service life to an average of 25+ years.
Low Noise & Maintenance: The oil-immersed structure operates at quieter levels (typically ≤55dB) and requires less frequent upkeep. The oil’s insulating and anti-rust properties reduce wear on internal components, cutting annual maintenance costs by 30% or more.
