Choose high quality light technique

With the continuous development of social civilization, light lighting has become reflect the image of the city's comprehensive municipal engineering. As an important part of city lighting, the product more and more get the attention of the society from all walks of life. If a road with good lighting production



with the continuous development of social civilization, lamp lighting has developed into a comprehensive municipal works reflect the image of the city. As an important part of city lighting, the product more and more get the attention of the society from all walks of life. If a road have good lighting products, can improve the traffic safety, improve traffic induction, reduce the crime rate, improve the road environment comfort, beautify the environment. Therefore, it is necessary to choose high quality lighting products.

when buy, first choose a lamppost brand of domestic normal manufacturer production, do not buy low price products. At the same time, pay attention to ask for the formal invoice, the invoice must indicate the name of the product and the contract, specification, quantity, price, amount, etc. ; Second, pay attention to the manual or packaging, whether the enterprise has passed the certification of quality system. In addition, still should refer to inspection report, especially check the electric shock protection, durability test Durability test, it is in order to determine product under specified conditions of use and maintenance of life, to predict or verify structure weak link and dangerous part of the test. 】 If the project is qualified; Third, check whether the product identification is complete. Normal product must be marked at least: trademark or name, product model specifications, rated voltage, rated frequency, rated power, rated power and safety sign is particularly important.

and the key is to consider the matter of line voltage drop. The method is appropriate to solve the problem of line drop cable. When the line drop meet the requirements, the current-carrying capacity of the cable has considerably more than required. When choosing a cable, therefore, should be more appropriate cable, can not only meet the requirements of reducing lamp voltage drop, and can save power.
