一、產(chǎn)品簡介 Brief introduction
光伏電纜的特性是由其電纜專用絕緣料和護套料決定的，經(jīng)過輻照加速器輻照以后，電纜料的分子結(jié)構(gòu)會發(fā)生改變，從而提供其個方面的性能?？箼C械載荷實際上，在安裝和維護期間,電纜可在屋頂結(jié)構(gòu)的銳邊上布線，同時電纜須承受壓力、彎折、張力、交叉拉伸載荷及強力沖擊。如果電纜護套強度不夠，則電纜絕緣層將會受到嚴重損壞，從而影響整個電纜的使用壽命，或者導(dǎo)致短路、火災(zāi)和人員傷害危險等問題的出現(xiàn)。
The characteristics of photovoltaic cable are determined by its special insulating material and sheath material for cable. After irradiation by irradiation accelerator, the molecular structure of cable material will change, so as to provide its performance in all aspects. In fact, during installation and maintenance, the cable can be routed on the sharp edge of the roof structure, and the cable must withstand pressure, bending, tension, cross tensile load and strong impact. If the strength of the cable sheath is not enough, the cable insulation will be seriously damaged, which will affect the service life of the whole cable, or lead to problems such as short circuit, fire and personal injury.
