Leakage of street lighting facilities is divided into "pole live" and "cable leakage". High Lumen Street Light Housing Manufacturers introduces the following scenarios for these two types of phenomena:
1. The cable insulation in the street light pole is damaged, which leads to the contact between the wire and the light pole, which makes the light pole electrified.
2. The lamp head is leaking. Although the lamp holder is designed with a waterproof function, the lamp holder may leak electricity after the insulation changes or the line is struck by lightning.
3. Water in the road surface intrudes into the interior of the light pole, resulting in leakage. When the city is flooded, if the street light pole is submerged in water, the water level exceeds the height of the light door, and the waterproof measures of the wiring head are insufficient, which will lead to leakage.
4. Cable insulation changes. Street lamp power supply lines are relatively long, some lines may be several kilometers long, and they are all buried in the ground. After a long time, the insulation will change due to erosion, or the cable sheath will be damaged due to the influence of external force. The reduction of cable insulation may lead to leakage.
