LED lighting will be used as a strategic new industry during the “Twelfth Five-Year Plan†period in Shanghai, and at least cover 30% of the general lighting system in Shanghai. This is the reporter obtained from the 2010 China (Shanghai) International LED Industrial Technology Exhibition and Forum held yesterday. Information.
At the 2010 Shanghai World Expo, LED lighting became the biggest highlight. The 1.007 billion LED chips not only solved the long-term problem of lighting technology for this World Expo, but also highlighted the important role of energy saving and emission reduction. On average, each LED lighting tube is at least 30% more energy efficient than ordinary fluorescent tubes, and its life cycle is 5-6 times that of ordinary fluorescent lamps. If LED lighting is applied to general lighting systems such as roads and tunnels in the city, it can be greatly Reduce the corresponding economic costs such as maintenance and social costs such as manpower.
“The Shanghai Eco-Home†case of the Puxi Park Urban Best Practice Area, its 14 LED technologies, has provided a demonstration for us to replace the traditional lighting sources with LED semiconductor lighting technology and apply it to the general lighting in the city. The role of sex." Dr. Yang Weiqiao from the Shanghai Industrialization Base of the National LED Semiconductor Lighting Project pointed out at the forum yesterday that "according to the '12th Five-Year Plan', Shanghai will regard LED lighting as a 'strategic new industry', with a focus on chips. Independent innovation and core equipment development, and apply this technology to more than 30% of the city's roads and other general lighting, to achieve 'post-World Expo' 'energy saving and emission reduction'."

Porcelain Disc Insulators are typically used on high tension power transmission towers. Suspension Disc Insulator are widely apply for higher voltage that beyond 33KV to provide insulation due to its shirt surface construction design. Each unit has a single porcelain shell bonded to a steel cap (above) and a steel pin (below). Disc Insulator are designed to link together into strings, typically of two or more, to provide much higher voltage protection than any single insulator. Disc Type Insulator comply with the IEC, BS. As standards, the glaze color of the insulators are brown, light gray, blue, etc. The specified suspension insulators differing in diameter, unit spacing and creepage distance can also be provided, in addition, according to special requirements, these insulators can be provided wit zinc sleeve pins.
