Cable Company Performed Combustion Test of Metro Special Communication Cable

News Recently, "arson" video can often be seen in WeChat group of cable company. After a large bundle of cables is ignited, a special person will record the carbonization height and flameout time after combustion. This is the combustion performance test of the subway special communication cable produced by the cable company. After many related tests of different combustion levels and the inspection by the third-party testing organization, the subway special communication cable of the cable company successfully passed the bunched combustion B performance test.

At present, the construction projects of domestic subway and light rail are increasing, and the amount of special communication cables for subway is also increasing. Because of its relatively sealed use environment, subway cables have extremely high requirements for flame retardant and environmental protection performance of cables. Customers also attach great importance to this indicator. The cable company started to develop subway special communication cables from 2012 . The original production of communication cables suitable for outdoor use has been changed into subway special communication cables suitable for use in confined spaces through technological improvement. The Hong Kong subway project was the first to use the cable company's first cable, which has been more than eight years. At present, the sales of subway special communication cables account for about 40% of the total sales of local telephone cables of cable companies, and show a gradual growth trend.

Recently, customers require cable companies to pay more attention to the flame retardant performance of subway special communication cables. In order to ensure product quality and improve the flame retardant performance index of cables, cable companies have conducted combustion performance tests on subway special communication cables. Since there is not much experience in testing the combustion performance of communication cables in the same industry, and the bunched combustion B performance is one of the most difficult levels, the cable company has conducted a total of 6 related tests. Summarize the experience from each test and finally pass the bunched combustion B performance test.

At the same time, the cable company is also actively seeking technical support from suppliers and customers. The supplier recommends raw material samples, which can be adapted to the existing production equipment after trial, considering processability and economy, and the supplier provides free combustion performance tests and orders for production after meeting the requirements, which also greatly reduces the cost of testing.
