High-temperature-resistant photovoltaic cable manufacturing method and cable processing structure

The invention discloses a manufacturing method of a high-temperature-resistant photovoltaic cable. The manufacturing method comprises the following steps: step 1, wrapping a copper wire with a first layer of sheath material by adopting extrusion equipment; step 2, feeding the copper wire wrapped with the first layer of sheath material into irradiation equipment for first irradiation treatment; step 3, feeding to extrusion equipment for wrapping with a second layer of sheath material; 4, the copper wire subjected to two-time extrusion is fed into irradiation equipment to be subjected to irradiation treatment again; 5, the cable subjected to twice irradiation is sent to cooling equipment for cooling treatment, the sheath subjected to multiple times of irradiation can resist high-strength temperature, the conditions of color fading, aging and fragmentation are not prone to occurring in the illumination environment, meanwhile, the irradiation structure can enable the cable protection sleeve to be irradiated more
