Insulation coordination refers to the surrounding environment and electrical insulation properties to choose products according to the requirements of use, and only within its lifetime based endured a variety of roles (such as voltage and other factors) when the intensity s cable, insulation coordination in order to achieve product The ultimate goal. Three Bay Electric Technology Department in reference to all the information in the following concluded: insulation coordination principle, low-voltage equipment for insulation coordination requirements of low-voltage electrical terminals in the application and design requirements: insulation coordination principle insulation co-ordination 1, insulation damage and influencing factors. One is the breakdown (thermal breakdown) that under the strong electric field, electric internal media due to dielectric loss and fever, if the heat is too late loss, the temperature continues to rise, leading to low molecular weight volatiles escape leaving the molecular structure of the material damage ph1.25 cable, finally resulting in insulation breakdown; breakdown factors: temperature - temperature, humidity decreased breakdown voltage material - humidity increases, the breakdown voltage of the voltage drop materials - action time voltage action time to grow, the breakdown voltage drop materials Frequency - Frequency increased breakdown voltage drop material thickness material - material thickness increase, cooling unfavorable breakdown voltage drop that second insulating material for insulation aging in equipment operation Under the effect of various factors in the process of, physically, irreversible chemical changes, resulting in a sharp change in the material electrical, mechanical properties and damage, for insulation aging. Such as: thermal aging, alone or insulating material under the combined effects of heat, oxygen, water, or the product of low molecular weight volatiles escape; generate radical chain reaction so that molecular chains participation; autocatalytic acceleration caused material damage; produce hydrolytic degradation; or produce polymer chain polymerization, leading to performance degradation or complete destruction of the material; in addition electrical aging, due to O3, nitrogen oxides, and other high-speed particles produced by partial discharge and partial discharge caused by dielectric loss resulting increase Materials heat, resulting in material degradation or completely destroyed. child row, science terms, meaning the terminal assembly for carrying or groups of mutually insulated and insulated parts for fixed support member. Terminal block is the role of the line within the screen devices and external devices connected to the screen, play signal (current and voltage) ... Their role is mainly used to pass an electrical or conductive. Terminal blocks, science terms, meaning the terminal assembly for carrying or groups of mutually insulated and insulated parts for fixed support member. Terminal block is the role of the line within the screen devices and external devices connected to the screen, play a role in signal (current and voltage) transmission. With terminal block terminal lines, making wiring beautiful, easy to maintain, at the time of connection between the main long-distance lines are secure, convenient construction and maintenance. s cable, cable, creating loose electrons supplied by Asahi Dongguan Shijie Xu Song Chong electronic products factory.
