Abstract：In order to study the crosslinked and electrical characteristics of insulation material for new ultraviolet crosslinking polyethylene (UV XLPE) cable, the loss rates of thermal migration and crosslinked efficiencies for macromolecular photoinitiating system and micromolecular photoinitiating system were tested. Then the electrical characteristics of crosslinking samples that initiated by two kinds of photoinitiating systems were measured at room temperature, respectively. In addition, a radial distribution model of UV XLPE crosslinked degree for cable core was deduced, and a mathematical analysis was made for the model. The analysis indicate that the loss rates of thermal migration for macromolecule photoinitiator and crosslinker are improved significantly than the micromolecule photoinitiator as well as crosslinker, and the crosslinking efficiencies of them are improved to some extent. Besides, the electrical performances of new UV XLPE were improved somewhat, and the breakdown performances can reaches a high point at the crosslinked degree is around 75%, the breakdown strength showed a trend of decline when it higher than the value. The error of the mean value for radial distribution mode between the nonlinear fitting method and actual measured is only five thousandths, so it has more accurate applicability on the experimental research of new UV XLPE.
