The insulation of the xlpe or pvc power cable needs to be protected when we are going to do the cabling no matter how thick it is. In general on the road surface, the xlpe or pvc power cable is buried about 0.7 meters deep in engineering construction. It is commonly used to cover the xlpe insulated power cable with cement cover and repair the road surface after laying. The quality is relatively poor, so if you want to lay xlpe insulated power cables more perfectly, there are 3 methods.

Cable Trench

The cable trench dug out under the sidewalk, put the cover plate, excavation construction, after the line only need to open the cover plate, it is more convenient, the cable trench is also divided into both sides of the bracket cable trench and unilateral bracket cable trench; 1m deep, 2m wide, unilateral support cable trench 1.65m deep, 1.5m wide, generally including 12 cables.

Of course, it can be increased or decreased according to specific circumstances. The advantages of this method are convenient cable release and maintenance. After one excavation, cables can be laid one by one, which is better but slightly more expensive.

Power Cable in Tunnel

In many cables, cable tunnels should be built, the size of which can be arranged according to the construction conditions and needs. Tunnel is divided into round pipe jacking type (general inner diameter 2~6cm), cast-in-place method (general internal size: 2 meters wide, 2.88 meters deep); It can hold about 36 cables. The pipe jacking type does not require road excavation, whereas the on-site casting type requires road excavation and the tunnel roof is 2 meters deep. This way is the most expensive, the advantages of cable construction is convenient, cable root number.

Hang the XLPE Power Cable

Setting and laying Method Power cable racks are generally hung by galvanized steel strands. When the weight of power cable is less than 2 tons per kilometer, 35 square millimeters of steel wire should be used and 50 square millimeters of steel wire should be less than 3.99 tons per kilometer.

The installation of fixed cables should consider the following points:

Well laid pvc insulated power cables are safer for future use, not only to prevent the gnawing of wild animals, but also to prevent the damage of farmers' tools that are unwitting in their daily work, as well as to prevent oxidation and bad air.
