Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a cable head insulating glue reinforced cable. Background Art

[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer. It is used to transmit electricity or information. Cables are usually used in various occasions, including underground, underwater, and aerial laying environments. They are widely used in various fields such as power transmission, telecommunications, signal transmission, measurement, and control. The cable head insulation glue reinforced cable is an improved cable structure. Its design focuses on strengthening the insulation of the cable terminal head and the connection strength between the cable and the terminal.

[0003] After searching, the patent number "CN220189260U" mentioned in the text that "the utility model relates to the technical field of power construction, and in particular to a cable head insulation glue reinforced cable, which separates multiple cable cores in a protective sheath through a partition, and the multiple cable cores are relatively independent to reduce their mutual influence. Once one group of cable cores is short-circuited and heated, the partition can ensure that the other cable cores can be used normally, and the reliability is high; it includes a protective sheath and multiple groups of cable cores; it also includes a partition, which is installed inside the protective sheath, and the partition divides the interior of the protective sheath into multiple channels, and the multiple groups of cable cores are respectively located in the multiple channels." When in use, multiple cable cores are separated in the protective sheath by partitions. The multiple cable cores are relatively independent to reduce their mutual influence. Once one group of cable cores short-circuit and heat up, the separation of the partitions can ensure that the other cable cores can be used normally, with high reliability. However, in complex environments, such as high humidity or water vapor intrusion, the inside of the cable head will be affected by water vapor, affecting the insulation performance. In addition, if the cable encounters abnormal conditions such as short circuit, overload, ignition of external fire source, etc. during the transmission of electric energy, it is very easy to cause a fire, which in turn leads to serious personal injury, property loss and large-scale power outages.

[0004] Therefore, we provide a cable head insulation glue reinforced cable to solve the above problems. Utility Model Content
