Anti-dropping device used by the electricity sector is broadly divided into two categories: First, the track type, track type was divided into the tube Orbital groove track type , these two methods are the first corner of the tower to install specially designed track, the operating personnel brake wheel up and down the tower will be connected to the ring of security group card (inserted) into orbit, fall protection function. These two tracks fall prevention device at the same time there are several shortcomings:
A rail mounting difficulties. Outdoor Tower general height of 15 meters above, install the hard track 10 meters or even tens of meters to corner of the tower, and meet the requirements of the process and intensity, the degree of difficulty can be imagined.
B, and costly. The tube-shaped track must be used between the tube structure in the two above and two tube connection structure to achieve a continuous orbit, steel consumption volume. Recessed track made from high-strength alloy, single m very expensive. Both tracks require a fixed firmly wi th the tower, fixed points, the installation cost is also high.
C, inconvenient to use. The two tracks anti-dropping device, brake wheel structure is complex, and more portable for workers, increase the labor intensity of the operating personnel.
D, post-maintenance volume. Tubular track and more control for hot-dip galvanizing, the track is generally 6 meters long, the scene more than $ root splicing can not be a good solution to both ends of the block, tube inner wall is prone to corrosion, groove track alloy material, although a good solution to the problem of corrosion groove inner diameter of the outdoor nudity is very likely to cause the tank fouling and affect the normal use, you must periodically clear slot.
E, its own security is not high. Tube type track material consumption a large amount of alloy village material is expensive, and can easily become the target of theft.
        Differential. It is similar to t he car to use seat belts, generally by the shell, spring plate, centrifugal cards, cables, or a special soft rope, anti-fall device in the upper and lower altitude operations personnel security there are several difficulties:
        A high cost. Spring plate, strand, or a special soft rope must be to reach the tower height requirements, manufacturing costs can be imagined.
        B, differential devices must be winding plate fixed to the tower, the upper strand or a special soft rope fixed in the tower lower part of the whole process to achieve the anti-fall, spring plate can not be solved long-term loss of elasticity and strand or a special soft rope rust and corrosion problems.
        C, a device by only one person to use, not the practicality of anti-dropping.
        Such devices are generally limited to workers protection when working at height transposition.
        Therefore, research and development and promote the use of low-cost, safe, reliable, practical and convenient high-altitude anti-fall device is not only the objective needs of the aerial work sector will also have a good social and economic value. In this case, our \"strand high-altitude anti-fall device to follow the above design principles have emerged.

Incandescent doomsday soon

\"The so-called road map, when complete phase-out of incandescent, and eliminated the manner in which the overall plan.\" China Lighting Association president Chen Yansheng said.

At present, the Chinese lighting electricity consumption of the entire society 12% of electricity consumption, more than 430 billion kwh. If replace all the incandescent to energy-saving lamps, the annual saving of 48 billion kwh, equivalent to 48 million tons of carbon dioxide emissions.

From 1996, China began the implementation of green lighting project. In 2008, the National Development and Reform Commission, and financial subsidies to promote efficient lighting products to bulk users and urban and rural residents to purchase energy-saving lamps were given a subsidy of 30% and 50%, but so far, China has given no specific time of the final phase-out incandescent tables.

I understand that, in addition to the timetable, National Development and Reform Commission is currently looking to gradually phase out incandescent supporting policies to promote energy-saving lamps and special planning.

Lv Wenbin, Director of Development and Reform Commission, Central Information Secretary energy saving, said that the future state will revise the performance standards of energy efficient lighting products and energy efficiency standards, to improve the detection and monitoring capabilities of national testing agencies on the quality of energy efficient lighting products, as well as to further improve the efficient lighting product quality regulatory system.

Energy-saving lamp enterprises directly benefit

In 2009, incandescent production of 3.76 billion, accounting for about one-third of world production, production of compact fluorescent lamps (CFL) 3.65 billion, accounting for more than 80 percent of world production. If the next few years gradually with energy-saving lamps to replace incandescent, energy-saving lamps will grow rapidly.

Anhui Shilin Lighting Co., Ltd., Sang Yong tree that, in addition to policies to promote the future with the improved performance of energy-saving lamps and the decrease in cost, the market competitiveness of energy-saving lamps will also be getting stronger.

At present, four of the A shares listed on the manufacturers of energy-saving lamps, namely Zhejiang Sunshine (600 261), Feile Audio-Visual (600 651), Foshan Lighting (000 541), and snow Wright (002 076). These four companies will become the direct beneficiaries of the road map.

Zhejiang Sunshine on the 25th announcement that the National Development and Reform Commission and Ministry of Finance in 2010 to promote efficient lighting task total of 9.25 million, accounting for the national efficient lighting products in 2010 to promote the mission total of 155.1 million (excluding high pressure sodium) 5.95% of the company in 2010 sales will be a big increase.
