What are the main preventive measures for the insulation resistance of cables  wires in Guangxi

At first, in order to accurately measure the test values of the insulation resistance r15s  r60s of the photovoltaic cable, we generally choose a large-capacity insulation resistance tester with a fast charging speed. According to the relevant regulations of China, the output short-circuit current of the insulation resistance tester should be greater than 0.5mA, 1mA, 2mA  5mA. In the occasions with higher requirements, the insulation resistance tester with larger output short-circuit current should be selected as far as possible.Guangxi wire cable 

In the insulation resistance test of photovoltaic cables, the insulation resistance value at a certain time cannot fully reflect the insulation performance of the test object. On the one hand, the insulation resistance of insulating materials with the same performance is small when the volume is large,  the insulation resistance is large when the volume is small. On the other hand, insulating materials undergo charge absorption ratio process  polarization process after applying high voltage. Therefore, the power system requires the measurement of the absorption ratio, that is, the ratio of r60s to r15s,  the polarization index, that is, the ratio of r10min to r1min, in the insulation test of main transformers, cables, motors, etc., to judge the insulation condition.

Then, for personal safety  normal testing, in principle, it is  allowed to measure the charged DUT in the photovoltaic cable insulation resistance test. Although measuring a charged DUT will  cause damage to the instrument (in a short period of time), the test results are inaccurate, because after electrification, the DUT will be connected to other DUTs, so the obtained results cannot truly reflect the actual data , but the resistance value is in parallel  series with other test objects.Guangxi cable

The "Jiayou" trademark registered by Guangxi Jiayou Cable Technology Co., Ltd. has been recognized as a famous trademark in Guangxi. Over the years, Jiayou has always adhered to technological innovation. While continuously increasing investment in technological innovation  product innovation, it also attaches great importance to brand building. In 2006, the factory established a factory enterprise business school, which is responsible for all aspects of employee training. At the same time, a brand building team headed by the factory director was established to promote the requirements of energy conservation, environmental protection  economic development in my country's power transmission  distribution industry; The factory continuously improves its own service system  gradually establishes a sales  service network throughout the region. It is famous for its excellent quality  thoughtful service,  has enjoyed a high reputation  influence in the electric power, construction, electromechanical  metallurgical industries in the region. , is a brand that has been recognized by the majority of users inside  outside the district,  has been continuously rated as "Guangxi Contract-abiding  Credit-Reliable Enterprise" by Guangxi Administration for Industry  Commerce  other units.

Today, when the quality of the domestic cable product market is worrying, it is particularly important to implement the concept of "responsibility to cast quality, integrity to guide development". Social responsibility is closely related. In recent years, Jiayou has established an enterprise production  operation style of "honesty  integrity". Through scientific  technological management, increasing investment in technological transformation, improving production efficiency,  actively carrying out energy saving  consumption reduction, the factory reduces product manufacturing costs  is in a leading position in the domestic cable industry. In order to continuously meet the requirements of market development  actively participate in healthy market competition Guaranteed.

Through unremitting efforts for more than ten years, the comprehensive strength of Jiayou has been greatly enhanced. Coupled with the rapid development of the national economy  the rapid growth of investment in fixed assets such as infrastructure, the sales output value in the past three years has remained above 30%. growth of.Guangxi cable manufacturer
