Title:
METHOD FOR MANUFACTURING WATER-TREE RETARDANT MEDIUM-VOLTAGE ETHYLENE-PROPYLENE INSULATED CABLE, AND CABLE
Document Type and Number:
WIPO Patent Application WO/2019/114533
Kind Code:
A1
Abstract:
A method for manufacturing a water-tree retardant medium-voltage ethylene-propylene insulated cable, and a cable. The structure of the cable comprises: a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer, and a sheath layer which are sequentially provided around a same axis from inside to outside; a cross-linked polyethylene semi-conductive shielding material constituting the conductor shielding layer; an ethylene propylene diene monomer insulating material constituting the insulating layer; a rubber semi-conductive shielding material constituting the insulating shielding layer; and a polyethylene sheath material constituting the sheath layer. The method for manufacturing the cable comprises the steps of: 1) manufacturing the conductor; 2) manufacturing the conductor shielding layer; 3) manufacturing the insulating layer; 4) manufacturing the insulating shielding layer; 5) sparsely winding a bare copper wire; 6) extruding a sheath material. Both the electrical performance and the mechanical performance of the cable manufactured by the method are higher than standard requirements.
