Solar street lamp installation drawing 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: the basic requirement of buried cable as follows: 4, to the tree good marks

the street lamp, buried cables and shop is the basis of the provisions have?

the power of the solar street lamp installation drawing at present stage by the previous empty frame power supply circuit into underground cables, replaced and foundation, the benefits of underground cable is high rationality, beautiful and easy, resistor smaller.

buried cable provisions of the basis of the following:

1, the dielectric strength of the cable can be higher, need to be 10 m above the mother.

2, cables of copper core cable

connection must use waterproof casing socket, copper core wire with copper waterproof casing socket, aluminium wire cable with waterproof casing socket of aluminum, copper and aluminum cohesion, with copper and aluminum cohesion waterproof casing socket.

3, cables must be sealing and moisture-proof, can't hurt.

4, tree good sign, the following must be in several parts of the shape sign

A, the start-stop end and the end of the route, B, route corner, C, cable joints.

5, pavement construction of cables for record, after if be in, all change, LED street lamp, also must have the relative records.

the pavement in the solar street lamp installation drawing cables shall comply with the provisions of the following

1, after installation, earthwork backfill to backfill soil, backfill earthwork backfill should be clamping and 15 - above the road 20 cm, of course, such as earthwork backfilling after falling tighter, will be with the road surface is flat.
