What common knowledge about cable reels should we know?
In addition to conducting handover tests and preventive tests for power cables, insulation tests should also be carried out during the construction process to identify and check the quality of the cables and the quality of the workmanship at various stages of construction. Tests should be conducted on the cable drum before laying to identify the quality of the cable; tests should be conducted after and before laying to check for any damage to the cable during installation; tests should be conducted after the completion of the cable joint to assess the quality of the joint; and tests should be conducted before and after cable maintenance to evaluate the quality of the maintenance. The main contents of the inspection are as follows:

In addition to conducting handover tests and preventive tests for power cables, insulation tests should also be carried out during the construction process to identify and check the cable quality and process quality at various stages of construction. Tests should be conducted before laying.Cable drumTests should be conducted before and after laying to identify any damage to the cables during installation; tests should be conducted after the completion of cable head construction to identify the quality of the cable head; tests should be conducted before and after cable maintenance to identify the quality of the maintenance. The main contents of the inspection are as follows:
(1) Cables should be arranged neatly, the fixing and bending radius of the cables should comply with the design drawings and relevant regulations, the cables should be free from mechanical damage, and the labels should be installed completely, correctly, and clearly. There should be no oil leakage in the terminals and intermediate joints of oil-impregnated paper insulated cables and oil-filled cables.
(2) There should be no debris in the cable trench and tunnel, the cover plates of the cable trench should be complete, and the lighting, ventilation, drainage, and other facilities in the tunnel should meet design requirements.
(3) The marker stakes for direct buried cables should match the actual path, and the spacing should meet the requirements. The markers should be clear, firm, and durable.
(4) The markers and night lighting devices on both banks of the underwater cable route and in the anchoring prohibition zone should meet design requirements.
The use of mobile cable drums is similar to the power sockets we encounter in daily life; they are both mobile power sources for facilitating daily production and life. Therefore, the safe use of mobile cable drums is also similar to the use of power strips in our lives. Whether it is precautions in the work environment or protective measures when using power strips, both have commonalities. So what safety knowledge about electricity should we know?
First, mobile cable drums should not be overloaded during use. To ensure that there is no overload operation in the circuit, each product in the mobile cable drum is equipped with overheating, overload, and leakage protectors, which will automatically trip in case of overload.
Second, high-power appliances are often equipped with three-core sockets to ensure safe grounding during power-on; all panels of mobile cable drums are equipped with three-hole grounding sockets.
Third, in daily life, when using mobile cable drums, copper wires or iron wires should not be used as substitutes for fuses, nor should enameled wires be used as substitutes for heating wires and other alternatives.
Fourth, when people leave, the power should be turned off, and the power switch should also be disconnected during power outages to avoid accidents when power is restored. In industrial settings, if a power outage occurs, contact electrical workers for inspection and only continue using after confirming there are no issues or after repairs.
The above is about the safety knowledge we should know.Cable drumI hope this sharing can help everyone!
