Waterproof photovoltaic cable

Abstract

The invention relates to the technical field of photovoltaic cables, and discloses a waterproof photovoltaic cable which comprises a first insulating sleeve, a photovoltaic cable core penetrates through a limiting hole, a flame-retardant layer is fixed to the outer side of the first insulating sleeve and the outer side of a heat-conducting sheet, a waterproof layer is fixed to the outer side of the flame-retardant layer, a heat-conducting rod is fixed to the outer side of the heat-conducting sheet, and a waterproof layer is fixed to the outer side of the heat-conducting rod. And the heat conducting rod penetrates through the flame-retardant layer and the waterproof layer and is connected with the second insulating sleeve. According to the waterproof photovoltaic cable, the first insulation sleeve plays a role in wrapping and protecting the photovoltaic cable core, the heat conduction piece and the heat conduction rod can play a role in heat conduction, a gap exists between the waterproof layer and the second insulation sleeve, wind can shuttle between the waterproof layer and the second insulation sleeve, and one part of the heat conduction rod is located between the waterproof layer and the second insulation sleeve, so that the heat conduction effect is good. The heat dissipation effect can be conveniently achieved, the flame-retardant layer can exert the flame-retardant characteristic, the waterproof layer can exert the waterproof effect, water can be drained through the water outlet, and water accumulation between the waterproof layer and the second insulation sleeve is avoided.
