The inspection and maintenance methods for firefighting wires and cables mainly include the following aspects:

Firstly, in terms of inspection:
1. Appearance inspection: Observe whether there are obvious defects such as damage, deformation, cracks, or skin peeling on the surface of fire wires and cables. These appearance abnormalities may indicate internal problems in the wires and cables, so they need to be detected and dealt with in a timely manner.
2. Identification inspection: Check whether the cable and incoming wires are labeled with circuit numbers, which should be clear and not easily faded. At the same time, check if there are any operations that change the surface of the sample, such as ribbon dyeing, labeling, or engraving, to ensure the accuracy and consistency of the identification.
3. Performance testing: Conduct electrical performance tests, such as insulation resistance, voltage resistance, capacitance, etc., to ensure that the electrical performance of wires and cables meets national standards. In addition, mechanical performance tests can also be conducted, such as tensile strength, bending radius, etc., to evaluate the mechanical performance of wires and cables.

Secondly, in terms of maintenance:
1. Regular inspection: The inspection content includes whether the equipment is operating normally, whether the fire prevention measures are complete, and whether the fire-fighting equipment is in good condition. Inspection personnel should possess corresponding technical knowledge and skills, be able to identify problems and solve them in a timely manner. The inspection cycle can be set according to the usage and environment of the equipment, usually once a year. In special circumstances, the inspection cycle can be shortened.
2. Cleaning and maintenance: Keep fire wires and cables clean, regularly clean the outside of the equipment and fire equipment to prevent dust and debris from accumulating and affecting the normal operation of the equipment. At the same time, necessary lubrication and maintenance should be carried out on the wires and cables to ensure their normal operation.
3. Timely maintenance: Once damage or malfunction is found in the fire protection wires and cables, they should be repaired or replaced in a timely manner. Especially for fire alarm equipment and fire extinguishing equipment, once they malfunction, they must be repaired or replaced in a timely manner, otherwise it will have a serious impact on fire prevention and control.

Overall, the inspection and maintenance of firefighting wires and cables is an important task that needs to be carried out regularly to ensure the safety and reliability of the wires and cables. At the same time, it is also necessary to enhance fire safety awareness, strengthen the daily management of fire equipment, and provide strong support for preventing fires and reducing fire losses.
