How to prevent wires and cables from being damaged by external forces?
The normal and stable work of power cables is of great significance to ensure the normal operation of enterprises. Electricity cannot be separated from wires and cables. Problems with wires and cables are directly related to all aspects of people's lives. However, sometimes wires and cables will be damaged by external forces. .
During the storage, transportation, laying and operation of cables, they may be damaged by external forces, especially the directly buried cables that are already in operation, and they are vulnerable to damage in the ground construction of other projects. Such accidents often account for 50% of cable accidents. In order to avoid such accidents, in addition to strengthening the quality of work in all aspects of cable storage, transportation, laying, etc., it is more important to strictly implement the ground breaking system.
How to prevent wires and cables from being damaged by external forces? In order to prevent the wires and cables from being damaged by external forces, there are more and more wire and cable protection products. Wire and cable protection pipes have a good protection effect on wires and cables. Wire and cable protection pipes include stainless steel hoses, galvanized hoses, and packages. Plastic hoses, flat plastic hoses, explosion-proof hoses, nylon bellows, plika hoses and other categories have different performances for protecting cables. Metal hoses are more resistant to wear and corrosion than non-metallic hoses , Good resistance to compression and tensile, more durable, longer life. The wire and cable protection pipe protects the wire and cable from external force damage, so the protection pipe is well used in wire and cable laying facilities. Wire and cable manufacturers
How should I choose the path of buried cables?
How should I choose the path of directly buried cables? Directly buried cables follow the requirements of the specification. After the direct buried cable trench is dug, a sand cushion is laid at the bottom of the trench, and debris in the trench is removed, and then the cable is laid. After that, it is necessary to fill the sand immediately and cover the cable with a layer of brick or concrete slab to protect the cable, and then backfill a cable laying method. For the route selection of buried cables, Liaocheng wire and cable manufacturers believe that the following requirements should be met:
Avoid areas that are strongly affected by acid, alkali corrosion or stray current electrochemical corrosion; when there are no protective measures, avoid areas that are harmed by termites, heat sources, and vulnerable to external forces.
Wire and cable manufacturers The cable should be laid in the trench, and the soft soil or sand layer with a thickness of not less than 100mm should be laid along the upper and lower sides of the cable; the protection should be no less than 50mm on both sides of the cable along the entire length of the cable The board and protective board should be made of concrete.
It is located in the frequently excavated places such as urban roads. It can be paved with protective markings on the protection board. It is located in the suburbs or open areas. The distance along the straight line of the cable path is about 100m. Turns or joints should be clearly oriented. Sign or stake.
When wire and cable manufacturers use cable through corrugated pipes to lay trenches, plain concrete with a thickness of not less than 100mm should be cast along the entire length of the top of the corrugated pipe, and the width should not be less than 50mm outside the pipe. The cables may not contain armor. Finally, Liaocheng wire and cable manufacturers reminded that when laying cables, pay attention to geological conditions and choose appropriate cable models and specifications, mainly paying attention to rodent, termite, etc. damage, depth, temperature, bending radius and other factors.
