Description

Technical Field

[0001] This utility model belongs to the field of power cable technology, specifically, it relates to a branch-type power cable that is easy to connect. Background Technology

[0002] In modern buildings, especially mid- to high-rise buildings, large factories, and cultural and sports venues, power distribution systems are complex and demand is high. Traditional power cables often require complex splicing processes when branching, which is not only cumbersome but also makes it difficult to guarantee the quality of the splices, thus affecting the stability and safety of the system.

[0003] The utility model with announcement number CN220085674U belongs to the field of cable equipment technology, and in particular to a metal-shell fireproof pre-branched power cable, including a main shell and a branch shell fixedly connected to one side of the main shell. A spacing adjustment component is provided between the main shell and the branch shell. This utility model improves the cable sealing effect through the setting of left and right sealing rings, resulting in better dustproof, moisture-proof, and waterproof performance. The use of aluminum foil insulation layer, asbestos insulation layer, and fiber insulation layer improves the heat insulation effect, preventing heat transferred from the metal shell from acting on the main cable and branch cable, thereby increasing the cable's service life. The external spacing adjustment component allows adjustment of the spacing between the main shell and the branch shell, improving the device's versatility without affecting cable threading or the insulation layer's coverage of the main cable and branch cable.

[0004] However, the above-mentioned patent still has the following problems: the connection of the branch power cable will bend during use, the interface is easily worn, which can easily cause cable damage, affect the service life of the branch power cable, and cause problems such as loosening and aging at the joint.
