Characteristics of Photovoltaic Cables

The characteristics of photovoltaic cables are determined by their specialized insulation and sheath materials, known as cross-linked polyethylene (PE). Irradiation by an accelerator alters the molecular structure of the cable material, thus improving its various performance characteristics. Mechanical Load Resistance: During installation and maintenance, cables can be routed along the sharp edges of star-shaped structures and must withstand pressure, bending, tension, cross-tension loads, and strong impacts. Insufficient sheath strength will severely damage the cable insulation, affecting the overall lifespan of the cable or leading to problems such as short circuits, fires, and personal injury hazards.
