Underground Cables Laying Requirements
First of all, the underground cable must have a insulation test. When the underground cable to lay before and after in the ground.

Thirdly, mark piles or hand-hole wells should set at the corners of the joints of underground cables. This is to facilitate maintenance and inspection. The distance between adjacent hand hole wells should be less than 50m.
Fourth, the cable specifications and models should indicate on the middle joint of the cable and the terminal head with an indicator.

Different functions
The main features of overhead cables are easy maintenance, low maintenance costs, and low cost. However, due to exposure to the air. And it is easily affected by the weather.
Underground cables have the characteristics of long service life, stable transmission, and high transmission reliability. Not susceptible to external interference. Because it is laid underground. And its safety performance is better.
Different places of use

Underground cables are mainly used in densely populated urban areas.
Advantages of Underground Cables
First, the transmission current is more reliable. Besides, not easy to get corroded by moisture in the air. And not easy to get interfered with by the outside world.
Secondly, the carrying capacity of the transmission current is greater. The conductors used in underground cables have higher transmission efficiency and lower power transmission losses. And the transmission line of the underground cable can reach 20 loops, which is 5-10 times that of the overhead cable
Thirdly, underground cables are installed underground, which can make the city more beautiful and increase the living comfort of urban residents.
