Can XLPE Cable Be Buried Directly?

Cross-linked polyethylene (XLPE) insulated cables are used in industrial installations, industrial installations, and so on. Resistance to the heat of XLPE insulated cables has been improved greatly by transforming its linear molecular structure into a main network molecular structure. The highest temperature that polyvinyl chloride (PVC) cables can withstand is generally 70℃, and the temperature of XLPE insulated cables can reach 90℃. In this way, it is not easy for XLPE insulated cable to melt after heating, and its performance is maintained well. As a result, XLPE cables have obvious advantages compared with PVC cables.

XLPE insulated cables have good performance and lots of advantages. It is strongly resistant to acid, and alkali oil. Moreover, When the XLPE cable burns, water and carbon dioxide. As a result, XLPE cable is less harmful to the environment than PE cables, which makes it satisfy the need for safety. Based on good insulation performance, the insulation resistance of XLPE cable is further expanded. In addition, XLPE cable is not much affected by temperature. Laying XLPE cables should consider many factors. For example, the temperature should not fall below 0℃. XLPE cables can be directly buried with attention to the cable laying environment. When there is no risk of machine damage and chemical leaching, XLPE insulated cables over 1000 volts could be buried directly using armor. However, XLPE insulated unarmored power cables are below 1000 volts. Armored power cables could be buried in the mud with a depth of no less than 0.7 meters. The cable is covered with sand and then laid with bricks, which are then compacted with earth. Faults of power cables appear in joints between cables, so there is no middle linker in common condition. If the joint must be set up, the joint should be set up in the joint well for future maintenance and repair. In addition, when laying the cable under the road, the cable needs to pass through the steel pipe to avoid damage.

Different types of XLPE insulated cables are used in different conditions. In the case of no mechanical stress, XLPE insulated PVC sheathed power cables can be buried or used with the pipe. In addition, this cable is suitable for indoors and in tunnels. XLPE insulated PVC sheath double steel tape armored power cable also applies to the above four cases. XLPE insulated PVC sheathed fine steel wire armored power cables that can withstand external forces are installed in drilled shafts, water, and somewhere with a big drop.
