            Abstract : 
Cross-linked polyethylene (XLPE), as a dielectric material, has a wide application in power system. The security of the early stage cable is a problem due to the aging of XLPE. We investigated the XLPE by terahertz time-domain spectroscopy system, and calculated its refractive index, attenuation coefficient and dielectric constant, which provides valuable information to analysis the aging of XLPE.
