The problems that are easy to occur in the use of cables are basically the faults of cable insulation, accessories and outer sheath. Today, let's learn how to prevent these problems and reduce the harm caused by faults in the use of wires and cables. Cable line project can be said to be a systematic project. Only by implementing the whole process management from the aspects of design, construction, operation and maintenance can its safe operation be guaranteed.

Firstly, at the beginning of cable line engineering design, we should have a full understanding of the grounding system used by the cable and select the cable with appropriate voltage level to avoid the cable working under long-term overvoltage. The selection of outer sheath shall consider the service life and environmental requirements. The selection of cable sheath protector shall meet the requirements of relative grounding, so as to ensure that the protector can reliably pass through the grounding current without damage. Boyi cable produces power cables (YJV, yjv22, yjlv), distribution wires (BV, BVR, RVV, RVs), aluminum alloy cables (yjlhv), overhead cables, flame retardant and fireproof cables, rubber sheathed cables, control cables (KVV), special cables and other products, which are widely used in power grid, rail transit, new energy, aerospace, military, petrochemical, urban construction and other fields. It can meet the one-stop needs of customers.

Secondly, in the selection of cable laying path, the external environment with overheating, corrosion, hard objects and more rolling by external force shall be avoided, and the influence of internal factors causing overheating due to too concentrated cable laying, which can not diffuse heat in time. In addition, the cable path of double circuit power supply is not recommended to be laid in the pipeline of the same path to prevent simultaneous damage and large-area power failure. There is no trivial matter. We must take precautions.

When facing the problem of cable accessories, we should strengthen the selection of cables and cable accessories, manufacturer supervision, arrival acceptance and other work. All links are indispensable to ensure the quality of cables and cable accessories. After receiving the goods, the vulnerable parts of the cable not laid shall be sealed in time to prevent moisture from affecting the normal use.
