Photovoltaic dedicated cable

Optical cable is a kind of electron beam Cross-link cable, with the rated temperature of 120 ° C, which is equivalent to 18 years of service under the special continuous temperature of 90 ° C; When the temperature of the surface is below 90 ° C, its service life is longer. Usually, it is required that the service life of solar equipment should reach 20 to 30 years or more. A large number of DC cables in photovoltaic power plants need to be laid outdoors, and the environmental conditions are harsh. The cable materials should be determined based on their resistance to UV, ozone, severe temperature changes, and chemical erosion. Long term use of ordinary material cables in this environment will cause the cable sheath to be fragile and even decompose the cable insulation layer. These situations can directly damage the cable system and increase the risk of cable short circuits. In the medium to long term, the likelihood of fire or personal injury is also higher, greatly affecting the service life of the system. Therefore, the use of photovoltaic cables and components in photovoltaic power plants is very important. With the continuous development of the photovoltaic industry, the market for photovoltaic supporting components has gradually formed. In terms of cables, various specifications of photovoltaic cable products have been developed.

Characteristics of photovoltaic cables

The characteristics of optical cables are determined by their specialized insulation and sheath materials, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the square structure of the cable material will change, providing various aspects of its performance. In fact, during installation and maintenance, the cable can be routed on the sharp edges of the star top structure, and must withstand pressure, bending, tension, cross tensile loads, and strong impacts. If the strength of the cable sheath is insufficient, the insulation layer of the toilet cable will be severely damaged, which will affect the entire service life of the cable, or lead to problems such as short circuits, fire, and personal injury hazards.
