In recent years, with the continuous expansion of the city scale, the street lamp industry has flourished. However, some places have not kept up in time because of concepts, technology, management, etc., which has led to a series of security issues. The street lamps are wide-ranging, and it is very easy to cause serious personal safety accidents if they leak electricity. Not only does it bring suffering to the families of the victims, but the relevant government departments also have to bear huge financial compensation liabilities.
For example, at around 21:00 on June 15, 2012, an electric shock accident occurred at Miaoyuan Road in Yulin City, Guangxi, causing the man surnamed Wei to be shocked and sent to hospital for treatment. The family members of the deceased took the Municipal Engineering Management Office and the Housing Construction Committee to the court and demanded compensation for all losses. Finally, the municipal engineering management office compensated for a total of more than 430,000 yuan. The matter lasted for nearly a year and caused a major impact on the local area.
It is easy for us to find some streetlight electric shock accidents that have occurred in recent years.
The case is innumerable, which is why we don't pay attention to it, don't think about it, and seek solutions to the problem of street lamp leakage.
Street lamp leakage accidents mainly focus on lamp pole leakage. There are many reasons for the leakage of the pole. Some of them are aging of the cable insulation in the pole and igniting with the pole. Some of them are unqualified by the electric light source. If the ballast is broken down, the pole is charged, or the wiring terminal is burnt. The pole is charged, and the light pole caused by vandalism is charged. Finally, the pole is charged by the harsh natural environment, such as lightning, typhoon, earthquake and other natural disasters.
Most of the accidents caused by lamp pole leakage occur in wet weather during rainy weather, especially in the summer of thunderstorms. This aspect is due to the fact that in summer, high-temperature roads and other facilities operate at higher temperatures and humidity, and the cable insulation layer is prone to aging and breakdown, resulting in leakage of the lamp post. On the other hand, due to the lack of clothes in the summer, the bare skin is easy to touch the metal part of the pole, and the exposed part of the shoe and the earth form a loop, causing electric shock. In winter and spring, the shoes are well insulated and even the electric shock is rare. Causing a fatal accident.
Let's talk about the solution one by one.
1,
Aging of the cable insulation inside the pole is ignited with the pole
In general, standard cable insulation should be able to be used for no less than 15 years and should be replaced before expiration. In addition, the cable should be secured in the center of the pole without leaning against the wall of the pole.
2,
The electric light source is unqualified
At present, with the promotion of LED light source, the advancement of technology, strict control when purchasing the light source, requiring IP65 level, can minimize the possibility of accidents.
3,
Wire terminal discharge
Most of the current wiring methods use the method of peeling and winding. In this way, the joint resistance is large, the sealing effect is poor, and the insulation life is short. When the insulation tape is wrapped for 3-5 years, it will be slack. If there is moisture or water immersion, it will discharge. This is the main factor that causes the pole to be charged. Before everyone did not pay attention, there is no good way to solve this problem.
Now, Bingyue Electric (Shanghai) Co., Ltd. specializes in the development and production of an insulated and sealed waterproof connector for street lighting applications, which solves this problem well.

Livelight caused by man-made damage
Mainly refers to the cable is broken after theft, the cable break is exposed in the pole, it is easy to cause a discharge accident. In some places, the use of aluminum (aluminum alloy) cable instead of copper cable can reduce the possibility of theft, but the use of aluminum cable facing the copper-aluminum transition connection problem, the copper-aluminum transition special connector should be used. At present, there are also places where cameras, burglar alarms, etc. are used, but the cost is too high. One of the most effective and economical methods at present is to improve the cable joints in the mounting holes, and to fix them on the terminal block with an integral connector, so that the thief has no way to start. Copper-aluminum transition special connector and integrated connector solution can be consulted by Bingyue Electric (Shanghai) Co., Ltd.

Poor natural environment causes the pole to be charged
Mainly refers to two pieces. First, the water overflows through the mounting hole. If the cable connector can be waterproof and sealed, there is no need to worry. Please contact Bingyue Electric (Shanghai) Co., Ltd. for waterproof sealing connector. On the other hand, it refers to lightning weather. Lightning strikes on the pole. Because the grounding of the pole is not good, the lightning strikes and burns the electronic equipment. At the moment of lightning strike, the pole is charged. The streetlight project must ground each pole in strict accordance with the safety standards, and regularly inspect and inspect the grounding wire and the connection, and find out the problem in time. It is also possible to increase publicity efforts, and put measures such as lightning protection signs and anti-shock signs on the poles to prevent pedestrians from standing around the poles during lightning strikes and when flooding over the poles.
The lamp pole leakage accident has brought enormous life and economic losses to the people, and we have to pay attention to it. Bingyue Electric (Shanghai) Co., Ltd. is committed to solving the above problems, and we believe that this is the social responsibility of the company.
