Power cable is used to transmit and distribute power cable, power cable commonly used in urban underground power grid, power station leads lines, industrial and mining enterprises within the power supply and across the river underwater transmission line. Wire and cable industry is China's second largest after the automotive industry. Here we introduce the power cable laying method and its advantages

1. laying directly

Direct laying is the most direct and economical way to lay the power cable, according to the selected laying line dug the cable trench directly buried laying, the method construction is simple, low cost, but vulnerable to damage, will be subject to corrosion and pests

2. Cable tunneling

When the number of power cables is large and is susceptible to external damage, it is advisable to use cable tunneling in order to avoid damage and reduce the impact on other underground pipes.

3. Cable laying

When the number of power cables is large, and vulnerable to external damage, in order to avoid damage and reduce the impact on other underground pipes, should be used cable laying. Cable discharge laying safe and reliable, more advantages, but the project cost is higher.

4. Cable trench laying

When there are more power cables (no more than 12) or are susceptible to external damage, many cables are laid in parallel with cable trenches in order to avoid damage and reduce the impact on other underground pipes. This method is used in power lines for high-rise buildings and factories. Cable trench laying ditch should not have water and oil, stent to be anti-corrosion treatment, stent spacing between 0.5 of 1.5.

The above is about the power cable laying method and the selection of a brief introduction to learn more about the power cable content, please pay attention to kingsignal official website.
