I. Core Definition and Functions of the Product
Power Bushing, also known as high-voltage bushing or outlet bushing, is a key component connecting the internal windings of high-voltage equipment to external circuits. Its core function is to provide reliable insulation protection while realizing efficient power transmission, withstand high voltage, large current, and mechanical stress during equipment operation, prevent safety hazards such as leakage, creepage, and electrical breakdown, and ensure the stable operation of the power system.
Its core functions include three aspects: first, insulation isolation, which effectively isolates high-voltage live parts from grounding enclosures and other components, ensures insulation gaps, and eliminates leakage accidents; second, mechanical support, which fixes conductive components and bears mechanical stress during equipment vibration, transportation, and installation; third, conductive transmission, which serves as a transition component for current conduction, ensuring stable transmission of high-voltage current without affecting equipment operation efficiency.
