[0018] Optionally, a spiral steel wire is provided inside the spiral anti-scratch strip.

[0019] The present invention provides a photovoltaic cable with a surface anti-scratch structure, which has the following beneficial effects:

[0020] The photovoltaic cable with a surface scratch-proof structure generates heat when the core body is in use through the heat dissipation block, the heat dissipation rod and the heat dissipation assembly. The phase change materials in the heat dissipation blocks can absorb the heat generated by the core body. At the same time, the heat dissipation rod conducts heat, and the phase change materials in the cavities between the first inner tube and the first outer tube absorb heat, which can reduce the temperature of the photovoltaic cable when in use and improve the stability of the photovoltaic cable when in use.

[0021] The photovoltaic cable with a surface anti-scratch structure has a tensile inner core, a reinforcing component and a spiral steel wire. When the photovoltaic cable is in use, the plurality of steel wires distributed in a ring shape and the spiral steel wire inside the spiral anti-scratch strip can improve the bending resistance of the photovoltaic cable, effectively prevent the photovoltaic cable from being broken due to excessive bending of the cable, and increase the service life of the photovoltaic cable.

[0022] The photovoltaic cable with a surface anti-scratch structure has a flame-retardant component, and the outer wall of the second outer tube is sprayed with a flame-retardant polyurea elastomer coating, which can play a flame-retardant role in the event of a fire. At the same time, the aluminum oxide powder in the flame-retardant component has a good flame-retardant effect and is an inorganic substance. It does not produce thick smoke when burned, which can effectively prevent the photovoltaic cable from being quickly ignited, causing the fire to spread rapidly.

[0023] The photovoltaic cable with a surface scratch-proof structure uses a dividing plate, a first insulator and a second insulator. The dividing plates made of insulating materials divide the plurality of wire core components. Together with the first insulator and the second insulator, when the photovoltaic cable is in use, the wire core body can be insulated and protected, thereby improving the safety and stability of the photovoltaic cable when in use.

[0024] The photovoltaic cable with a surface anti-scratch structure has a spiral anti-scratch strip and a wear-resistant layer. The wear-resistant layer is made of polyvinyl chloride plastic. The spiral anti-scratch strip can prevent the photovoltaic cable from directly contacting the ground. When the photovoltaic cable contacts the ground, the wear-resistant layer of polyvinyl chloride plastic can prevent the photovoltaic cable from being directly damaged when rubbing against the ground, thereby affecting the service life of the photovoltaic cable.
