Analysis On The Development Status Of Pre-insulated Bushing

pre insulated sleeve, also known as self-extinguishing tube, is woven with alkali-free glass fiber yarn. It has excellent properties such as fire prevention, heat insulation, insulation, and flame retardancy; pre insulated junction sleeve can be used in industrial electronic wiring, coil wrapping, electromechanical matching, pipeline anti-corrosion, computer peripherals, electrical instruments, power communications, aerospace, automobiles, military industry, metallurgy, petrochemicals, power and other fields. Due to its wide range of applications and excellent performance, it has been rapidly rising in China in recent years. The country has also vigorously supported the development of this industry and launched many good news.

Analysis of the development status of insulated joint sleeve
According to incomplete statistics, there are more than 300 glass fiber casing enterprises registered with my country's industrial and commercial departments. Among them, there are 5 super-large enterprises with an annual production scale of more than 30,000 tons, 15 large enterprises with an annual production scale of about 10,000 tons, more than 150 medium-sized enterprises with an annual production scale of more than 1,000 tons and less than 10,000 tons, and more than 100 small and micro enterprises with an annual production scale of less than 1,000 tons and hundreds of tons.
According to market demand forecasts, the annual compound growth rate of global glass fiber casing will exceed 6% within 10 years. The annual growth rate from 2011 to 2017 in the United States was 3%, Europe was 4.5%, Asia was 9.1%, and my country was as high as 11%. According to industry statistics, the total output of glass fiber casing in my country reached 580,000 tons in 2015, and it is expected to reach about 850,000 tons in 2017. The China Glass Fiber Sleeve Industry Association recently formulated the "13th Five-Year Plan" development plan for my country's glass fiber industry, and the goal proposed is to achieve a total output of 2 million tons of glass fiber yarn nationwide, of which the proportion of internationally leading pool kiln drawing technology will reach more than 85%. The reinforced fiber used to reinforce thermosetting plastics and thermoplastics will reach more than 550,000 tons, and the total amount of glass fiber for glass fiber casing and reinforced fiber rubber products will also reach a scale of about 800,000 tons.
