The utility model discloses a novel photovoltaic cable for an overwater photovoltaic power generation system. The novel photovoltaic cable comprises insulating wire cores, a filling layer, a moisture blocking layer, a flexible buffer layer and a sheath layer which are sequentially arranged from inside to outside, the cable also comprises a waterproof layer, and the waterproof layer comprises a central waterproof layer disposed outside the filling layer, a waterproof reinforcing layer disposed outside the flexible buffer layer, and an integral waterproof layer disposed outside the sheath layer. The filling layer and the flexible buffer layer are made of foaming type polyolefin materials; and the waterproof layer is made of a polyurethane material. The cable is light in weight, the contact surface between the cable and water is effectively reduced, the probability that moisture enters the cable is reduced, and the insulation wire cores are prevented from being corroded or broken down due to damp.
