solar garden light with long time after the hard to avoid can appear some fault, the bo ao 【 Beijing bo ao education group was founded in 1999, is a professional medical training institutions and the network education platform, training products include countries practicing doctors' qualifications examination, the nurse qualification examination, health professional and technical qualifications, the examination of practicing pharmacist qualification examination and medical examination of all major and subject, and bear the provincial health department of continuing medical education programs and network information technology support. 】 To analyze the garden light failed several big reason. 1, the material don't pass a low quality of garden light failure is there much factor. Main show is: less wire containing aluminum, lead is hard, thin insulating layer. 2, design is not reasonable on the one hand is overloaded. With the continuous development of city construction, garden lamp also extends continuously, the new garden light often near which courtyard lights, which received circuit, combined with the advertising career developing rapidly in recent years, advertising load were accordingly on the garden light, garden 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. 3, poor quality of construction, many manufacturers for cause of failure for a larger proportion of construction quality. Main performance: one is the cable trench 【 In cable trench is to change electric power or telecommunications cable laying and facilities of the underground pipeline, palisade structure is also been laying cable facilities, such as rectangle, circle, arched pipeline structure. 】 Depth is not enough, sanding 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. 4, form a complete set of engineering quality is not good garden light cable generally spread on the sidewalk. The pavement construction quality is poor, ground subsidence, the cable force deformation, cable sheathing. Especially in northeast China Northeast China, is a geographical cultural regions and economic regions of China, is not administrative region; The word 'northeast', originally found in the rites, fang '. 】 In the alpine zone, winter arrived, the cable and the soil to form a whole, once appear subsidence, ground will be a tear at the bottom of the garden light foundation, and the summer rainfall, will burn out in basic root.
