Introduction of protective measures for cable terminal block

At present, the installation position of outdoor cable terminal block is relatively concealed, The possibility of suffering direct lightning stroke is small, but after all, some cables are connected with overhead lines or other electrical equipment, or will be affected by lightning current. Therefore, Shanghai Youle electric proposes that more effective lightning protection measures must be taken to ensure the safe and stable operation of terminal blocks in cables.

1. When installing the terminal block, the contact surface of the terminal shall be polished and coated with conductive paste to make the terminal and lead clip have good contact, meet the requirements of connection strength and electrical performance of the two, and reduce the chance of heating.

2. When using the terminal blocks, the construction personnel should resist and refuse to use the spare parts that do not meet the national standards, and control the use of materials. The purchasing staff should visit the grassroots more to understand the use of the purchased items in the installation process, timely collect the use opinions, select the cable accessories from the national designated manufacturers, select good wiring terminals and fittings, so as to avoid problems caused by unqualified quality standards in operation.

3. The facilities that affect the safety of terminal lines should be cleared and rectified to ensure that there are no obstacles around the lines. The distribution lines led out by cables should be inspected regularly to reduce the peripheral fault factors and natural hazards of the distribution lines.

4. It is necessary to consider the power and capacity of the user's electrical equipment, pay attention to the field investigation, make the power utilization plan in advance, reasonably distribute the three-phase load, and consider the economy and safety of power consumption.
