[0002] Environment, energy and development are the three core themes of concern in today's world. The emission of large amounts of greenhouse gases and other harmful substances from traditional fossil fuels during use is considered to be the main cause of global warming. The non-renewable nature of fossil fuels and the worsening environmental pollution they cause have prompted countries to strengthen scientific and technological innovation in the energy field and strive to seek alternative energy technologies. Compared with traditional energy, solar energy has gradually become an important topic of research and development for its clean, environmentally friendly, huge and inexhaustible reserves, and easy access and transportation. It is widely used in many fields such as power generation, transportation, automobiles, and even national defense.

[0003] The widespread use of solar energy has led to the rapid development of supporting facilities such as cables and connectors. Due to the influence of objective factors such as the solar energy collection and conversion environment, solar cables need to have higher quality requirements to meet the needs. Traditional solar cables generally include cable cores and sheaths, with simple structures, and cannot play a good compression role. They are easily deformed or even broken by pedestrians or vehicles, and do not have a good fireproof effect. Utility Model Content
