YUANNENGJI U stvari, i industrijski plastični materijali i aluminijske legure mogu zadovoljiti zahtjeve, but plastics are far from meeting the requirements in terms of thermal conductivity, and are also prone to aging in the wind and rain outdoors, reducing the life of the lamp, so aluminum alloy is the best choice. In terms of thermal conductivity, it is second only to silver, copper, and gold. Gold and silver are too expensive, and the weight of copper is a problem. Aluminum is the best choice. Now many radiators are made of aluminum, which is perfect for the heat dissipation of lamps.
There is a passivation layer on the surface of aluminum alloy, which can prevent the outside world from corroding the aluminum alloy, so it is suitable for use in outdoor environments, greatly increasing the service life of the lamp. The zinc layer of hot-dip galvanized parts is uniform and smooth, without burrs, nodules, and unnecessary agglomerations. The thickness of the zinc layer is 65-90um. It is found that street light poles are often passed by passers-by, and the characteristics of solar lamps in outdoor working environment will produce zinc and zinc non-ferrous metal coating on their surface. The compressive strength of aluminum alloy street lights is relatively low. Since aluminum alloy street lights have many advantages that other street lights cannot match, customers can use them with confidence. Aluminum alloy street lights have been widely used, making the compressive strength of aluminum alloy street lights reach the T6 standard. After hot-dip galvanizing, electrostatic spraying is performed. When we produce street lights, we hot-dip galvanize their surfaces.
Although the bending radius of aluminum alloy cables is small, the internal space of street light poles is very narrow. Whether it is threading clamps or connecting tube technology, the bending radius of aluminum alloy cables in street light poles exceeds the allowable range of cables.
Due to the high cost of threading clamps, the branch connection of aluminum alloy cables in most street light projects currently adopts aluminum connecting tube crimping, and the cable conductors are electrically and mechanically connected through aluminum connecting tubes. Since the connecting tubes are all through holes of the same diameter, when the branch line is introduced, one side of the branch will be compressed and the other side will be loose.
The quality of aluminum alloy cable crimping directly affects the reliability of electrical connections. Poor crimping will not only cause line failures, but also have a great impact on the life of the lamp. Stoga, a new technical solution is needed to solve the above problems.
Light poles are commonly made of steel conical light poles, which are beautiful, strong, durable, easy to make into various shapes, simple processing technology, and high mechanical strength. Commonly used conical light pole cross-sectional shapes include round, hexagonal, octagonal, itd., and the taper is mostly 1:90, 1:100. The wall thickness is generally selected at 3-5mm according to the stress of the light pole. Since the working environment of the street light pole is outdoors, in order to prevent the light pole from rusting and corrosion and reduce the structural strength, the light pole must be treated with anti-corrosion. Anti-corrosion mainly takes preventive measures against the causes of rust. Anti-corrosion should avoid or slow down the influence of factors such as moisture, high temperature, oxidation, and chlorides.
