Factory of Post Insulator:
Advantage of Composite Station Post Insulator:
Composite insulators are suitable for substations, because it is difficult to detect zero-value insulators in stations due to power failure, and it is inconvenient to clean, and it is difficult to carry out post-maintenance with porcelain and glass insulators. For the existing substation, the composite insulator may also be replaced according to the site pollution degree and the actual situation.

About the production details：
Wuhan Line Power Transmission Equipment Co., Ltd has about 150 employees. The company's composite insulator injection implement three shift operations. All the front-line production personnel are trained and skilled, they have a very high level of understanding to their respective operating procedures and quality control requirements. The quality of the test personnel in our company is relatively high, all inspection and test personnel must be getting on post by hold a certificate after they pass the company's internal training, and the company invite external authorities to conduct professional training on high-voltage test personnel and other special work types, to enable the test personnel could complete the tests independently according to the national and international standards, the electric power industry standards and the relevant regulations of enterprise standards in the state grid corporation of China, they are skilled in operation and have a certain ability to analyze test results.
Marking on the first sheds of the insulators, normally shall print the company name, strength, sercial no ect., specific information could be put on the sheds if needed.
