At the meeting of Shanghai electrical engineering design research society BBS and new technology and new product introduction, liu lei, deputy chief engineer of Shanghai gaoqiao cable group, introduced the pre-branch cable products with mineral insulation in his opinion, which "will provide new options for the overall fire safety of buildings and guarantee the fire rescue" in his report.

Liu lei's report has attracted a large number of audiences in the building electrical industry at home and abroad, which also reflects from the side that building electrical fire has become an issue that cannot be ignored at present. It is understood that in recent years, with the increasing severity of electrical fires in buildings, the public's awareness of electrical safety has been rising, and flame-retardant wires and cables may face both development opportunities and severe challenges.

Wang chuanbin, senior deputy general manager and chief technology officer of far east cable co., LTD., pointed out at the second Asian summit on high-end wires and cables that hundreds of thousands of electrical fires occur in China every year, accounting for more than 30% of all fire accidents, and over 60% of the major fires caused by electrical faults in the three years from 2010 to 2012. According to the information released by the fire bureau of the ministry of public security this year, there were 113,000 electrical fires nationwide in 2013, resulting in 703 deaths and 515 injuries, with direct property losses reaching 1.85 billion yuan.

The severity of electrical fires may spur demand for flame-retardant wires and cables. Philip redburn, interjay's director of wires and cables, said recently that the proportion of major fire accidents caused by electrical causes has been high for years. The fire resistance and fire resistance characteristics of electrical lines are important factors for fire electrical causes. Therefore, fire accidents occur frequently and consumers' demand for product durability is the factor affecting the growth of demand for fire retardant cables.

The severe situation of electrical fire will also enhance the performance requirements of flame-retardant wire and cable, which will also be a big challenge for domestic wire and cable manufacturers. "Now there are more and more high-rise buildings, the fire safety level requirements are much higher than before." Zhou heping, chairman of wall nuclear materials and the actual controller, believes that the cables used in the past can be flame-retardant, but now require power to be on for three hours after a fire, so only super-refractory materials can make a difference.

"The selection of fire-resistant cables in civil buildings should not only meet the fire protection requirements, but also take the cost into consideration. In the opinion of wang jinyuan, chief engineer of electrical engineering of China northeast architectural design and research institute, it is more reasonable to select the grade of fire-resistant cables according to the continuous running time of fire-fighting equipment in fire, besides the nature and scale of buildings.

China's wire and cable companies, compared to

Europe and the United States

Japan and other developed countries generally have weak capabilities in product and technology research and development. Gao qingguo, honorary President of wire and cable branch of China electrical equipment industry association, was outspoken on the wuwei county wire and cable industry association member conference held in 2013

cable

80% to 90% of the products in the manufacturing industry are medium and low-end products with homogenization. It is known that flame retardant wire and cable belong to high profit, high value-added products, its research and development, manufacturing difficulty is significantly higher than ordinary wire and cable products.

Although the challenge is great, but there are still a few domestic enterprises have entered the field of flame-retardant wire and cable and the first taste of sugar.

Chen zhi, President of Shanghai yongjin cable group, said proudly recently that fire-proof cable will become his company's hit product. The successful launch of this product marks the successful transition of Shanghai yongjin cable group from low value-added traditional cable to high value-added fireproof cable.

Ye benkai, chairman of Shanghai gaoqiao cable group, said many people did not understand the company's promotion of fireproof cable products in previous years and even said it was "unnecessary". But now, fire safety awareness is rising, the government is also more and more attention.

Hundreds of thousands of electrical fires a year could boost demand for flame-retardant wires and cables. In this regard, domestic wire and cable production enterprises need to work hard to overcome the challenges caused by technical deficiencies, firmly grasp the good opportunities.
