Research on New Type Environmental Polypropylene Insulated Medium Voltage Power Cable

The crosslinked polyethylene insulating material commonly used in the cable is thermosetting plastic,which is difficult to recycle,crosslinking and depletion time,which is much higher than the thermoplastic insulated cable.A rated voltage of 26/35 kV power cable insulation environmentally friendly polypropylene,its production process is different from the ordinary crosslinked polyethylene insulated power cable,through the selection of the modified polypropylene as a new environmentally friendly insulating material voltage cables,the use of rational production process and product structure,to achieve mass production of polypropylene insulated cable.The product is operating normally operating up to 105℃,with large transmission capacity,green environmental protection,low cost,etc.;its performance passed type testing,but also can improve the reliable operation of the cable.At present,polypropylene insulated cable is in the blank in the domestic market.The application and popularization of this research have important guiding significance for the development of polypropylene insulated medium voltage power cable.
