Photovoltaic cable with high factor value and production process thereof

The invention discloses a photovoltaic cable with a high dyne value and a production process thereof, the photovoltaic cable comprises a conductor, an insulator wrapping the conductor and a sheath wrapping the insulator, and the sheath is made of an improved irradiation crosslinking low-smoke polyolefin material containing a lubricant with ultra-high molecular weight. The surface of the cable subjected to sheath extrusion shows uniform roughness, and the dyne value of the cable subjected to sheath extrusion after irradiation is greater than or equal to 36. According to the photovoltaic cable and the production process thereof provided by the invention, the sheath adopts the improved irradiation cross-linked polyolefin, so that the surface of the product has the characteristics of uniform roughness, good surface tension performance and the like, and the product has good adhesiveness with glue during subsequent production, so that the adhesiveness between the cable and a connector is stronger, and the service l
