Terminal suppliers, Xu Chong Song (certified), Dongguan, Dongguan Shijie terminals by Xu Song Chong electronic products factory provided. Dongguan Shijie Song Chong-wook Electronic Products Factory (chuangxs.1688.com) is specialized in the "terminal, plastic shell connectors, cables, connectors" of the enterprise, the company adhering to the "honesty, hard service" concept, for You provide the highest quality products and services. Welcome to inquire! Contact: Mr. Hu. Terminal detector detects a terminal located more versatile instrument Rally have European standard, European standard instrument universal testing machine terminals companies that can pull pressures on terminals connected test analysis and robustness condition. European standard instrument Rally test terminals can easily withstand the force and the force deformation. Terminals gradually widely applied to various fields, in terms of passing electrical conductive connections played a role in reducing the workload and cost of consumption, production and use to bring a lot of convenience, to avoid a lot of trouble. So as to simplify the product structure, the purpose of manufacturing cost savings. Therefore, the benefits brought by the terminal detection combined with market analysis for 804 terminals, it is recommended for the terminal equipment can detect professional testing equipment for testing. Common terminal testing equipment: tools, microscopes and optical imaging instrument. Insulation coordination is defined according to the requirements of the product and the surrounding environment to select electrical insulation properties, and only within its lifetime endured a variety of roles (such as voltage and other factors) based Terminal manufacturers love when strength can be achieved with insulation products 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 caused by insulation breakdown last; breakdown factors: temperature - temperature, humidity decreased breakdown voltage material - humidity increases, the breakdown voltage of the voltage drop of materials - the role of time voltage is applied 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 a variety of devices during operation Under factors, 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 heating the material, leading to performance degradation or complete destruction of the material.
