This paper introduces the renovation project for a single-circuit XLPE cable line being converted into dc operation after its second failure under 35 kV ac. This is the first time ever in China for ...

Abstract: Because of temperature gradients and inhomogeneous cooling rates after extrusion, the performances of HVDC XLPE cable insulation at radial position are not uniformly distributed. DC ...

The load varies periodically, but the peak current of power cable is controlled by its continuous ampacity in China, resulting in the highest conductor temperature is much lower than90℃, the permitted ...

The P/B ratio shows how a stock's market price compares to its book value. It helps gauge whether a stock is undervalued or overvalued relative to its net assets.
