How To Lay High Mast Cables?

Do you know how to correctly lay high mast cables? There is a lot of professional knowledge involved. Phoebus Light is a high mast enterprise with more than ten years of manufacturing experience and is willing to share it with you.

The laying of high mast cables should be carried out according to the specified depth and path. The general depth should not be less than 0.7 meters to prevent the high mast cables from being damaged by external forces. The path planning should be reasonable to avoid conflicts with other underground pipelines. The high mast cables should be prevented from being mechanically damaged during the laying process. The high mast cables should not be dragged on the ground. Both ends should be made into flares according to the standard to facilitate threading. Use high-quality high mast cables to ensure good insulation performance. The crimping of the wire nose and the thickness of the insulation wrapping should meet the requirements to prevent phase-to-phase short circuits during operation. Aisle pipes need to be added for special areas, such as crossing roads. The production and installation of aisle pipes must meet the standards to ensure the safety of high mast cables. At the same time, high mast cable markings should be done to facilitate subsequent maintenance and repair.

number of high mast cables

High masts generally require 4 wires, namely: a ground wire, a neutral wire, a phase wire, and a control wire.

Wiring method of high mast wires

1. Ground wire: The ground wire is the protection wire of the high mast and needs to be connected to the ground rod of the lamp pole to ensure personal safety.

2. Neutral line: The neutral line is the current return line of the high mast. It needs to pass through the switch and the electric meter to enter the lamp and provide the electric energy required by the lamp. It is generally wired inside the lamp pole of the high mast.

3. Phase line: The phase line is the power supply line of the high mast. It needs to be connected to the lamp head board of the high mast and connected to the lead on the lamp head board.

4. Control line: The control line is the control line of the high mast. It needs to be connected to the light control and time control equipment to control the switch of the lamp.

When wiring, you need to pay attention to the following points:

1. The connection of the wire must be firm, and the junction box must be reinforced.

2. The length of the wire should not be too long. Too long will easily increase the circuit impedance, resulting in excessive line voltage drop, affecting the normal lighting of the lamp.

3. The route of the wire should avoid crossing with high-voltage wires or other wires to avoid interference and damage to the line.

4. The wiring of the control line should follow the "three capitals" principle, that is, the phase line, neutral line, and control line need to be laid separately to avoid cross-interference.

High mast cable maintenance and care

1. Regular inspection

The lifting high mast cable of the high mast should be inspected regularly to observe whether the high mast cable surface is damaged, aged, or corroded. If any abnormality is found, it should be handled or replaced in time.

2. Cleaning and drying

Keeping the high mast cable clean and dry is an important measure to extend its service life. Dust and debris on the surface of the high mast cable should be cleaned regularly, and the high mast cable should be kept away from a humid environment for a long time.

3. Lubrication and maintenance

For high mast systems with pulleys or guide grooves, the pulleys and guide grooves should be lubricated and maintained regularly to reduce the friction resistance of the high mast cable during the extension and retraction process and reduce the degree of wear of the high mast cable.

Answers to common questions

1. Why does the high mast need 4 cables?

The high mast needs 4 wires because it needs a power supply, leakage protection, control, and grounding protection, and these functions require different wires to complete.

2. How should the thickness of the high mast cables be selected?

The thickness of the high mast cables should be selected according to the distance of the power supply line and the power of the lamp. Generally, the greater the power of the lamp, the greater the thickness of the wire should be.

3. Can the control line and power line of the high mast be mixed?

The control line and power line cannot be mixed and should be laid separately, following the "three-way" principle to avoid interference.
