How Thick Should the Bushing Wall Be?
When installing a wall bushing, one key question stands out: how thick should the bushing wall be? The right thickness ensures optimal protection, durability, and performance. Let’s explore the factors to consider and why Hewei’s wall bushings are the ideal choice for your needs. Why Bushing Wall Thickness Matters The thickness of a wall bushing […]
Comparison between porcelain and silicone rubber for external insulation on high-voltage bushings
In the current high-voltage insulating bushings market, porcelain bushings and composite material bushings are engaged in differentiated competition. Porcelain bushings, relying on mature manufacturing processes, high insulation reliability, and aging resistance, still maintain a dominant position (accounting for approximately 60%-70% of the market share), widely used in traditional power transmission and transformation scenarios. Composite material […]

Hewei Powers the Future of Grid Reliability Powering Modern Grids Starts with Reliable Insulation In today’s electrified world, uninterrupted power transmission is fundamental to both urban infrastructure and industrial development. A key player behind the scenes of this power stability is the High Voltage Porcelain Bushing—a component engineered to safely channel electricity through grounded barriers […]
Tipos de ensayo de materiales
What Is Material Testing? Material testing is the process that indicates or measures the properties or reactions of certain materials like metals, plastics, or ceramics under different conditions. The data or analysis collected from the test of materials helps determine the compatibility of CNC materials with various applications, including machinery components, tractor parts or construction machinery parts. Most companies have […]
Cómo seleccionar el pasamuros de polímero adecuado para sistemas eléctricos
With the demand for energy-efficient and compact power infra beginning to take root, the significance of the trustworthy high voltage insulation components has increased more than ever before. One such vital component is the polymer wall bushing, which has a critical role in electrical safety and system stability at substations, switchgear cabinets, and transformers. At […]
¿Para qué sirve un casquillo en un transformador?
A bushing in a transformer is a crucial insulating component. It allows electrical conductors to pass safely through grounded transformer tanks. Bushings ensure insulation and prevent energy loss. They also protect the transformer from external environmental factors. Bushing transformers are designed for high-voltage applications. They maintain system stability and efficiency. Without bushings, transformers would face […]
Soluciones de campo: ¿Cómo solucionar rápidamente problemas de sobrecalentamiento en terminales de 110 kV?
Infrared detection image of overheating part of 110kV transformer bushing The locking nut is loosened due to the vibration of the body and the conductor during operation. It was found that the pressure between the terminal cap and the contactor rod was insufficient. After re-tightening, the DC resistance test was qualified. Because there may be […]
What Is a Heavy Current Wall Bushing and Why Is It Crucial in Power Systems?
Who needs heavy current wall bushings?Engineers, utility providers, and manufacturers in high-voltage electrical systems rely heavily on heavy current wall bushings for safe and efficient energy transfer across insulated barriers, such as walls or transformer casings. What is a heavy current bushing?A heavy current bushing is a critical component designed to safely pass large electrical […]
Core Loss and Copper Loss in Transformer
Every kind of electrical equipment will happen to power loss occurs during long time operation, and the transformers are no exception. As the main equipment for voltage transform and power transmission, transformers are widely used in Power Grid. These power losses are mainly divided into copper loss (load loss) and Iron loss (core loss) Copper […]
Why Are Designs in Current Transformers Important for Electrical Accuracy and Safety?
Current transformers (CTs) are often small in size but play an essential role in power systems to be compromised by their apparent inconspicuousness. They form the basis for safe monitoring and the accurate measurement of high-voltage currents, especially in industrial and utility-scale electrical systems. Though many are concerned about ratings and usage, one of the […]
