The characteristics of photovoltaic cable are determined by its special insulation material and sheath material, which we call cross-linked PE. After irradiation by the irradiation accelerator, the molecular structure of the cable material will change, thus providing its performance in all aspects. Resistance to mechanical loads In fact, during installation and maintenance, cables can be routed on sharp edges of roof structures, and at the same time, cables must withstand pressure, bending, and tension

The cables used in the low-voltage DC transmission part of the solar photovoltaic power generation system have different requirements for the connection of different components due to different use environments and technical requirements. The factors to be considered generally include: the insulation performance, heat resistance and flame retardancy, aging performance, wire diameter specifications, etc. The connecting cable between the storage battery and the inverter is required to use multi strand soft cables that have passed UL test

PV cable performance and irradiation processing are special, so the following points should be paid attention to during irradiation: a. Before irradiation, check whether the conductor of each cable head is fully grounded. It is strictly prohibited to irradiate the cable without grounding. b. The absorbed dose of insulated wire core and sheath during irradiation is qualified by hot extension test

China is a large country of energy production and consumption, but its energy exploitation and utilization technology is backward, the proportion of traditional high energy consumption industries is significant, and the energy consumption per unit GDP lags behind that of developed countries. The contradiction between energy supply and demand will further intensify. At the same time, China is the largest developing country in the world, with rapid economic development, and the growth rate of energy consumption in China ranks first in the world
