Ultralow-temperature-resistant environment-friendly photovoltaic cable

The utility model discloses an ultralow-temperature-resistant environment-friendly photovoltaic cable which comprises an inner core frame, three wire grooves are formed in the side face of the inner core frame, wire cores are movably sleeved with the three wire grooves, a heat preservation layer is movably sleeved with the outer portion of the inner core frame, and a net sleeve frame is movably sleeved with the outer portion of the heat preservation layer. The outside of the net sleeve frame is movably sleeved with an insulation heat insulation layer, and the outside of the insulation heat insulation layer is movably sleeved with an outer sleeve protection layer. According to the scheme, heat preservation and heat storage are achieved through the heat preservation layer, heat can be effectively isolated through the inner core frame and the insulation heat insulation layer, internal and external heat exchange is prevented, the cold resistance is improved, and the photovoltaic cable can adapt to the day and nig
