Which failure affect light work properly

What are the common faults affect high lamp normal work? High lamp manufacturer small make up to you, the main contents are as follows:

1. Poor quality of construction

because construction quality caused by the fault for a larger proportion. Mainly as follows:

( 1) 。 The depth of the cable conduit is not enough, sanding cover brick construction according to the standard;

　　( 2) 。 Corridor pipe production and installation does not conform to the requirements of both ends not made syndromes according to the standard beep mouth;

　　( 3) 。 Shop when cable dragging on the ground;

　　( 4) 。 Not according to the requirements of standard construction, basis of embedded pipe is mainly embedded pipe carefully, coupled with a certain amount, difficult in cable, in appears at the bottom of the base & other; Die bending & throughout; Situation;

　　( 5) 。 Wire nose and insulation wrapped thickness is not enough, after a long run would interphase short circuit.

　　2. Material don'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.

　　3. Form a complete set of engineering quality is not good

high lamp cable generally spread on the sidewalk. 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 garden lamp base, and by the summer rain, will burn out in basic root.

　　4. Design is not reasonable

on the other hand is overloaded. With the continuous development of city construction, coupled with advertising career developing rapidly in recent years, the advertising of load are also relevant in high lamp, make the 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.
