The temperature of the variable frequency cable laying environment should not be lower than 0 degrees Celsius, and the temperature of the fixed laying cable should not be lower than -10 degrees Celsius, because when the laying temperature is lower than this limit, the cable signal transmission quality is adversely affected, and under such temperature conditions Cable laying can also cause problems such as poor laying and easy looseness, so we should avoid laying the cable at too low a temperature. Kvvp26*2.5 copper tape shielded control cable
Obviously, this will greatly affect the service life of the system. The characteristics of photovoltaic cable are determined by the special insulation material and sheath material of the cable. We call it cross-linked PE. After the irradiation of the irradiation accelerator, the molecular structure of the cable material will change, thus providing its performance. . Mechanical load resistance In fact, during installation and maintenance, the cable can be routed on the sharp edges of the roof structure while the cable is subjected to pressure, bending, tension, cross-tension loads and strong impact.
If the cable jacket is not strong enough, the cable insulation will be severely damaged, affecting the life of the entire cable or causing problems such as short circuits, fires and personnel hazards.
