Photovoltaic Cable PV Cable Solar Cable Manufacturer hot selling 1.5mm2 to 35mm2
Photovoltaic cable structure
1, IEC 60228, 5 class conductor: stranded tinned copper
2, insulation: cross linked low smoke halogen free flame retardant polyolefin insulation
3, sheath: cross linked low smoke halogen free flame retardant polyolefin
The difference between the two
Photovoltaic cablesexposed to sunlight, solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation.
In Europe, when the sun will lead to the field temperature of the solar systemup to 100 degrees C. At present, we can use a variety of materials are PVC, rubber, TPE and high quality cross link material,
But unfortunately, the rated temperature of 90 degrees C rubber cable, and even the rated temperature of 70 degrees PVC C cable is often used in the outdoor, obviously, this will greatly affect the system's service life. Anti mechanical load.
In fact, during installation and maintenance, the cable can be wired to the sharp edge of the roof structure, while the cable is subjected to pressure, bending, tension, cross tension load and strong impact.
If the cable sheath strength is not enough, then the cable insulation layer will be seriously damaged, thus affecting the life of the entire cable, or lead to short circuit, fire and personnel injury risk and other issues. The radiation cross link material has high mechanical strength, cross link process changes the chemical structure of the polymer, the meltable thermoplastic material conversion of fusible elastomer material for non cross links radiation significantly improved the thermal properties of the cable insulation material mechanical properties and chemical properties.
