Description

Technical Field

[0001] This utility model relates to the field of conductor insulation core technology, specifically a copper-aluminum composite conductor insulation core for cables. Background Technology

[0002] Power cords are electrical wires that transmit current. They are indispensable in homes, construction sites, and industrial production. With the development of society and the economy, the demand for power cords and cables has grown rapidly, and the quality requirements for power cords are constantly increasing.

[0003] For example, application number CN 216084350 U3 discloses a copper-aluminum composite conductor insulation core for cables that uses a fusion welding method between a solid aluminum rod and copper stranded wire to make the connection more complete. However, in this case, the conductor core directly transitions from the aluminum rod to the copper stranded wire. In actual conduction, the conductivity of the aluminum rod is different from that of the copper stranded wire. When current passes through, the fusion surface will heat up, causing the aluminum rod and copper stranded wire to overheat and melt. Moreover, the cable will generate a lot of heat during power transmission. During use, the cable will be subjected to external pressure and corrosion from rain and moisture. Therefore, a copper-aluminum composite conductor insulation core for cables is needed to improve the above problems. Utility Model Content
