the street lamp, buried cable laying and what are the basic requirements? The street lamp by previous aerial circuit to underground cable, and basic is replaced, the advantage of the underground cable is high efficiency, beautiful and good, less resistance. The basic requirement of buried cable as follows: 1, the cable insulation performance requirements higher, to more than 10 m ohm. 2, cable conductor connection requires the use of casing pressure, casing pressure welding wire with copper, aluminum wire with casing pressure welding of aluminum, copper and aluminum transition, transition from copper aluminum casing pressure. 3, cable must be sealed and waterproof, can't hurt. 4, to the tree good signs, here are A few places is A must to set up the sign A, line up the beginning and the end, B, line corner, C, cable junction. 5, cable laying construction should have record, if there is any change in the future, also needs to have the corresponding records. Cable laying should follow the following requirements 1, after the installation is complete, must carry on backfill earthwork, backfilling of earthwork compaction and 15 and above ground 20 cm, such as earthwork after natural down tight, with the ground is flat. 2, set up signs along the way, and clear cable type, date, to the related parameters.
In an age when solar light is increasingly important, the researchers believe manufacturers should pay close attention to their results.
