Now the cable poles on the road are pulled up one by one, and the overhead cables will be designed for buried cables and will be converted to buried cables. It takes a lot of steps to change the overhead cable to the buried cable. In addition to the smooth laying of the cable underground, it is necessary to try to maximize the construction process. The cable poles on the road are pulled up one by one. will be converted to buried cables. It takes many steps to change the overhead cable to the buried cable. In addition to laying the cable underground smoothly, during the construction process, it is necessary to minimize the living and normal electricity consumption of the residents.
The overhead wires are turned into cables, and the communication optical cables are also laid in the cable trenches at the same time. The street lamp cable fault detector is divided into three methods according to the treatment and solution of buried line faults: analysis and judgment method, simple ground fault detector testing fault and intelligent cable fault testing instrument testing fault, which is very convenient and can accurately locate within one meter. There is no need to dig through the road many times to search for it, which can save a lot of manpower, material resources and financial resources.
Save maintenance costs. The underground cable detector can easily and accurately detect the direction and depth of underground communication cables and power cables without excavating the soil. It is an indispensable equipment and right-hand man for electric power, communication departments and factories and mines.
The relocation of power facilities this time mainly includes cable transformation of 26 10kV and 33 400V overhead lines, laying cables for more than 30 kilometers, and adding 19 500kV box-type transformers (air pressure variables) Transformer. Engineering (Engineering) is set to 24-hour uninterrupted operation, faster engineering (Engineering) progress (Pace). Change the unsightly condition of empty rack cables earlier.
The cost of buried cables is twice as high as that of ordinary cables. It is laid in the ground of 1~2 meters, with a width of about 50 cm. It is poured with concrete, and the environment is very strong. Wuxi cable fault maintenance is equipped with cable distribution boxes at intervals. If there is a cable fault problem, you can use the troubleshooting method to roughly locate the location of the cable fault, and then use a professional cable fault tracing and fault locator to locate. Generally, The range can be fixed within 1 meter. Before using the receiver and transmitter of the underground pipeline detector, a general inspection should be carried out to ensure that the battery power is sufficient and the functions of the instrument are normal.
If any of the following conditions exist, resolve the problem before using the instrument. The electromagnetic radiation (Radiation) produced by buried cables may be a threat to human exposure, which is also unscientific. The frequency of my country's power grid is generally 50 hertz (Hz), but the current mobile phone has reached more than white hertz and has already been overthrown.
