1. The vertical leather wire shall be insulated leather wire. The copper core shall not be less than 1.37 mm, and the aluminum core shall not be less than 1.76 mm.

2. When connecting the vertical rubber wire to the overhead conductor, it shall be symmetrically lapped on both sides of the pole. The lapping point shall be 400-600mm from the pole center, and both sides shall be consistent.

3. Method of connecting vertical line to power supply side

4. If the rubber wire is more than four meters long, it shall be fixed with a support in the middle. The insulated strand shall not be less than 7/1.0, and the single cross binding method in the standard issued by the terminal authority shall be used.

5. When the main line and the vertical line are of different metals, the interphase binding wire shall be used as the transition joint bow, and the longest bow shall not exceed 100mm.

6. The vertical rubber wire shall have black binding wire at the insulation support and shall not be wound with this wire.

7. Plastic pipe shall be added at the iron outlet pipe or ash pole hole of the power line, and the pipe length shall not be less than 200mm.

8. There can be at most one joint in the aerial section of the vertical line. The joint shall be wound 5-7 times on both sides and wrapped with adhesive tape. Different specifications cannot be connected.

9. The power cord that goes through the iron pipe and rod hole must not have a connector.

10. The vertical line is not allowed to pass through the high-voltage line.

11. 7/1.0 insulated stranded wire is required for the vertical line of the transformer pole near the high-voltage lead, and the connection between the vertical line and the main line shall be back buckled and then wrapped with binding wire for 30~50mm.

12. The vertical line of the street lamp shall be tightly bound, neat and appropriate, and the broken skin and exposed bare line shall be replaced.

13. The distance between the street lamp vertical line and the household line shall not be less than 50mm during the maximum swing.

14 During construction and maintenance, the power bow of the vertical line shall be tightened with pliers.

15. At most two wire ends can be pressed at each pressing screw of capacitor and ballast, and the bending direction of wire ends shall be clockwise and compressed with flat pads.

16. The zero line of the street lamp vertical line shall not be overlapped with the zero line of the user's household line to prevent the power supply from reversing from the user's meter when the zero line bow line is disconnected from the zero line.

17. The lighting of public toilets shall be in accordance with the standards for household lines issued by the Bureau.

18. After the horizontal line and vertical line of the long arm lamp (big shoulder lamp) are tied back on the same bottle, a transition bow should be left.
