Abstract

The utility model relates to a cable resistant to a high temperature and UV. The cable comprises insulated cable cores, a filling layer, a cladding, an inner sheath, an armor, and a UV-resistant outer sheath successively from inside to outside. The UV-resistant outer sheath is made of 90 DEG C thermoplastic halogen-free low-smoke flame-retardant polyolefin sheath material. By means of advanced irradiation crosslinking technology and the halogen-free low-smoke flame-retardant material, the cable is resistant to a high temperature, ozone, UV, water vapor, microbe, wear, oil and corrosion, and the cable has a strong short-time overload capability, a long service life and high tensile strength. Thus the cable can be widely used in various fields such as solar power stations and photovoltaic systems.
