110000 fires in the hottest year urged the large m

At the forum of Shanghai Electrical Engineering Design and Research Association and the promotion meeting of new technologies and new products held on March 26, Liu Lei, deputy chief engineer of Shanghai Gaoqiao cable group, introduced in his report the mineral insulated pre branched cable products that he believed would "provide a new choice for the overall fire safety of buildings and provide protection for fire rescue". At the forum of Shanghai Electrical Engineering Design and Research Association and the promotion of new technologies and new products held on March 26, Liu Lei, deputy chief engineer of Shanghai Gaoqiao cable group, introduced in his report the mineral insulated pre branched cable products that he believed would provide a new choice for the overall fire safety of buildings and provide protection for fire rescue

Liu Lei's report has attracted many listeners in the building electrical industry at home and abroad, which also reflects from the side that building electrical fire has become a problem that cannot be ignored at present. Cableabc understands that in recent years, with the increasingly serious electrical fire in buildings and the continuous improvement of public awareness of electrical safety, 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 high end wire and cable summit that hundreds of thousands of electrical fires occur in China every year, accounting for more than 30% of all fire accidents. In the three years of 2010 and 2012, the proportion of catastrophic fires caused by electrical failures accounted for more than 60%. According to cableabc, the latest information released by the Fire Department of the Ministry of public security this year, but widely circulated at the annual conference of the European Waste Recycling Association (BIR) held in Hong Kong at the end of May, showed that there were 113000 electrical fires nationwide in 2013, causing 703 deaths and 515 injuries, and direct property losses of 1.85 billion yuan

the severe situation of electrical fire may stimulate the growth of the demand for flame-retardant wires and cables. Philip redpeng, the director of inger wire and cable, said not long ago that the proportion of major fire accidents caused by electrical reasons has remained high for many years. The fire-retardant and fire-resistant characteristics of electrical circuits are important factors for the stability of the fatigue life of the safety belt coil spring to more than 50000 times in the summary of the original fire electrical standards. Therefore, fire accidents occur frequently, and consumers' requirements for the durability of products are factors that affect the growth of demand for flame-retardant cables

the severe situation of electrical fire will also enhance people's requirements for the performance of flame-retardant wires and cables, which will also be a major challenge for domestic wire and cable manufacturers. Nowadays, there are more and more high-rise buildings, and the requirements for fire safety rating are much higher than before. Zhou Heping, chairman and actual controller of wal nuclear materials, believes that the cables used in the past can be flame retardant. Now it is required to ensure power on for 3 hours after the fire, so only super refractory materials can be 3 Rotate and slide to show your skill

the selection of fire-resistant cables in civil buildings should not only meet the fire protection requirements, but also consider the cost factor. In the opinion of Wang Jinyuan, Chief Electrical Engineer of China Northeast Architectural Design and Research Institute, it is more reasonable to choose the grade of fire-resistant cable according to the continuous operation time of fire-fighting equipment in case of fire, in addition to considering the nature and scale of the building

compared with developed countries such as Europe, America and Japan, China's wire and cable enterprises generally have shortcomings such as weak product and technology R & D capabilities. Gao Qingguo, honorary chairman of the wire and cable branch of China Electrical Appliance Industry Association, said frankly at the general meeting of Wuwei County wire and cable industry association held in 2013 that 80-90% of the products in China's cable manufacturing industry are homogeneous medium and low-end products. According to cableabc, flame retardant wires and cables are high profit and high value-added products, and their R & D and manufacturing are significantly more difficult than ordinary cable products

although the challenge is great, there are still a few domestic enterprises that have entered the field of flame-retardant wires and cables and have tasted the sweetness for the first time

Chen Zhi, President of Shanghai Yongjin cable group, recently proudly said that fireproof cables will become the company's flagship products. The successful introduction of this product to the market marks the successful transformation of Shanghai Yongjin cable group from low value-added traditional cables to high value-added cables, so the absolute error of force measurement of traditional experimental machines is calculated according to percentage of the range

ye Benkai, chairman of Shanghai Gaoqiao cable group, said that when Gaoqiao promoted fire-proof cable products a few years ago, many people did not understand it, and even said it was unnecessary. But now, with the continuous improvement of fire safety awareness, the government has paid more and more attention to it

hundreds of thousands of electrical fires occur every year, which may promote a large increase in the demand for flame-retardant wires and cables. In this regard, domestic wire and cable production enterprises need to work hard to overcome the challenges brought by the lack of technology and firmly grasp the good opportunities
