Transformer Life Halved with Every 8°C Increase? Understanding Thermal Aging MechanismsThe length of time a transformer can operate normally under rated voltage and rated load is called the service life of the transformer. Materials used in transformer manufacturing fall into two main categories: metallic materials and insulating materials. Metallic materials generally can withstand relatively high temperatures without damage, but insulating materials will rapidly age and degrade when the temperature exceeds a certain value. Therefore, temperature is one of the main factors affectFelix Spark10/20/2025 -
How Hydraulic Transformers Enable Green & Smart Hydraulics1. About the Hydraulic TransformerA hydraulic system typically consists of a hydraulic power source (pump), actuators (hydraulic cylinder or motor), control components, and auxiliary parts. However, one critical component is notably missing—the hydraulic transformer. Hydraulic transmission is often compared to electrical transmission, and hydraulic control systems to electrical control systems, due to their strong similarities and corresponding functional components and parameters.

How Silicon Steel Reduces Transformer Core Loss？Why Silicon Steel Sheets Are Used in Transformer Cores – Reducing Eddy Current LossWhy reduce the other type of iron loss—eddy current loss?When a transformer operates, alternating current flows through its windings, producing a correspondingly alternating magnetic flux. This changing flux induces currents within the iron core. These induced currents circulate in planes perpendicular to the direction of the magnetic flux, forming closed loops—hence they are called eddy currents. Eddy current losEcho10/20/2025
