Why some damage to the solar street lamps
why some damage to the solar street lamps, solar street lamps widely popular in recent years, but the resulting problems are also many, such as street light not bright, or when the light is not bright, and so on, when such fault and there are many, the solar street light why failure?
, form a complete set of engineering quality is not high,
solar street light cable generally spread on the green belts. The pavement construction quality is poor, ground subsidence, the cable force deformation, cable sheathing. Especially in the alpine zone in northeast China, the winter arrival, make the cable and soil to form a whole, the ground once appear, settlement, will be a tear at the bottom of the solar street light base, and by the summer rain, will burn out in basic root.
, poor quality of construction,
because the cause of failure for a larger proportion of construction quality. Main show is a cable trench depth is not enough, sanding cover brick construction according to the standard; 2 it is aisle pipe production and installation does not conform to the requirements of both ends not made syndromes according to the standard beep mouth; Three is cable when the shop is dragging on the ground; Four is not in accordance with the requirements of standard construction is the foundation of embedded pipe, refined classification is mainly embedded pipe, coupled with a certain amount, difficult in cable, in the base at the bottom of the 'dead turn'; Five is the line nose and the thickness of insulation wrapped pressure is not enough, after a long run would interphase short circuit.
, unreasonable design of the
on the other hand is overloaded. With the continuous development of city construction, solar street light also extends continuously, the new tended to be near which solar street lights, solar street lamps which received circuit, combined with the advertising career developing rapidly in recent years, advertising load were accordingly on the solar street light, make the solar street light load is too large, cable line nose overheating, heat, insulation, a grounding short circuit, and so on and so forth; Is on the other hand, when light pole design only consider oneself circumstance of light pole, ignore the cable head space, cable head wrapped good later, most are even doesn't close the door, sometimes the cable length is not enough, joint production does not conform to the requirements, the causes of failure.
and material didn't pass the
it from years of treatment failure, material quality is low and there is a big factor. Main show is less wire containing aluminum, lead is hard, thin insulating layer. This situation is more common in recent years.
so failure is not just some solar street lamps or some environmental factors caused by man-made factors, the main reason is the solar street light caused by their design, material and so on reasons, so the quality is the key to solar street light good or bad.
