Jinlong Cable won the national invention patent for “high-resistance environmental protection and fire-fighting cable”

On July 11, Hunan Jinlong International Copper Group Changsha Jinlong Cable Co., Ltd. received the invention patent certificate of "High Resistance Environmental Protection and Fire Protection Cable" issued by the State Intellectual Property Office of the People's Republic of China. Inventors: Mao Yuming, Chen Shanqiu, Zhou Guoxin .

The three inventors succeeded in inventing the product after painstaking research. It is characterized in that in the structure of the conventional flame-retardant power cable, a high flame-retardant oxygen barrier layer is added, and the oxygen barrier layer material contains a large amount of hydrated hydroxide, and when the fire ignites the cable, the oxygen barrier layer The material releases a large amount of water vapor, which greatly reduces the flame temperature, effectively delays the spread of fire, and dilutes the harmful gases and fumes generated during the combustion process, facilitating fire rescue. It has been tested by the National Fireproof Building Materials Quality Supervision and Inspection Center. It is concluded that the flame retardant performance of the cable meets the requirements of Class 1A, and all other indicators are qualified.
