Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is increasingly widely used in China. In addition to the rapid development of government-supported photovoltaic power plants, private investors are also actively building plants and plan to put them into production and sell them globally. Solar modules. Therefore, the market demand for photovoltaic cables, a key component of solar energy technology, is huge, and the industrialization prospect is very broad.

      Insulation layer, the insulation layer is covered with a sheath, the insulation layer is a ceramicized polyolefin layer, and the sheath is a ceramicized polyolefin sheath; the ceramicized polyolefin layer is used as the insulating layer, and the ceramicized polyolefin sheath is used, which has better Good resistance to high and low temperature and electrical insulation, flame retardant, fire resistance, safety, environmental protection, ozone resistance, good economy. There is a buffer tube between the insulating layer and the sheath, and there are multiple buffer tubes on the inner circumference of the buffer cylinder. Grooves, the outer peripheral surface of the insulating layer is provided with a plurality of grooves. The ribs corresponding to the grooves are clamped into the grooves, and there is a gap between the ribs and the grooves. When subjected to an external force, the gap between the rib and the groove buffers the effect of the external force, and has a strong resistance to mechanical impact.
