New energy wires and cables are usually composed of several wires or groups of wires, similar to rope cables. Each set of wires is insulated from each other and is usually twisted around a center with a highly insulating covering over the entire bread. Mainly set in the air or underground. The bottom is used for telecommunications or power transmission. Cables can be divided into power cables. Communication cables and control cables. So, are there any safety requirements when using new energy wires and cables? The details are as follows: 1. When the new energy wires and cables cross, the high-voltage cables should be under the low-voltage cables. If one of the cables passes through the duct for protection, or is separated by a partition within 1m before and after the intersection point, the smaller allowable distance is 0.25m. 2. When the cable is close to or crosses the heat pipe, if there are heat insulation measures, the minimum distance of parallel and crossing is 0.5m and 0.25m respectively. 3. When the cable crosses the railway or road, it should pass through the pipeline for protection, and the protection pipeline should extend 2m beyond the track or road surface. 4. The distance between the new energy wire and cable and the building foundation should ensure that the cable is buried outside the loose water of the building; when the cable is introduced into the building, it should pass through the pipeline for protection, and the protective pipeline should also exceed the loose water of the building. 5. The distance between the cable directly buried in the ground and the grounding of the general grounding device should be 0.25~0.5m; the buried depth of the cable directly buried in the ground is generally not less than 0.7m, and should be buried under the frozen soil layer. .
