Technical Field

[0001] The utility model relates to the technical field of insulated bunching conductors, in particular to a four-core parallel insulated bunching conductor. Background Technique

[0002] The full name of the parallel bunching conductor is the parallel bunching overhead insulated cable (Dayuan cable), which is a new type of low-voltage overhead insulated cable formed by connecting each (4) insulated conductors together with an insulating material connecting rib. Compared with other conductors, it not only occupies less space, saves channels, but also has simple construction and convenient operation and maintenance. In addition, the parallel bunching conductor can also reduce reactive power loss, improve voltage quality, and ensure more safe and reliable power supply. Therefore, it has received favorable comments from power supply enterprises and has often been used in the construction and transformation of low-voltage power grids in cities and rural areas in recent years.

[0003] At present, the four-core parallel insulated bunching conductor is formed by connecting each insulated conductor together with an insulating material connecting rib. However, during the transportation or handling of the existing four-core parallel insulated bunching conductor, the insulating connecting rib of the cable is prone to tearing due to torsion or collision, resulting in the separation of the four insulated conductors, thus affecting the subsequent use of the conductor. For this reason, we propose a four-core parallel insulated bunching conductor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a four-core parallel insulated bunching conductor, which has the advantage of anti-tearing, and solves the problem that during the transportation or handling of the existing four-core parallel insulated bunching conductor, the insulating connecting rib of the cable is prone to tearing due to torsion or collision, resulting in the separation of the four insulated conductors, thus affecting the subsequent use of the conductor.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a four-core parallel insulated bunching conductor, including an insulating sleeve, the insulating sleeve sequentially includes an insulating layer, a tensile layer, a flame-retardant layer and a wear-resistant layer from the inside to the outside. An upper clamping plate is arranged at the top of the insulating sleeve. An elastic clamping plate is arranged at the front end of the bottom of the upper clamping plate. The rear end of the upper clamping plate is movably connected to a lower clamping plate through a hinge. A positioning card slot is opened at the front end of the lower clamping plate.

[0006] Preferably, a conductor is arranged inside the insulating sleeve, and the number of conductors is four.

[0007] Preferably, the tensile layer is bonded to the outside of the insulating layer, the flame-retardant layer is bonded to the outside of the tensile layer, and the wear-resistant layer is coated on the outside of the flame-retardant layer.

[0008] Preferably, the material of the insulating layer is a polyvinyl chloride layer, the material of the tensile layer is an aramid fiber layer, the material of the flame-retardant layer is a phenolic fiber layer, and the material of the wear-resistant layer is a polyurethane layer.

[0009] Preferably, the length of the elastic clamping plate is less than the inner length of the positioning slot, and the elastic clamping plate is clamped inside the positioning slot.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] Please refer to Figures 1-5 , a four-core parallel insulated bundled wire, comprising an insulating sleeve 1, the insulating sleeve 1 sequentially includes an insulating layer 11, a tensile layer 12, a flame retardant layer 13 and a wear resistant layer 14 from the inside to the outside.

[0026] Through the above technical solutions, by setting the tensile layer 12, the tensile strength of the surface of this wire is improved, and the risk of this wire being torn is reduced. By setting the flame retardant layer 13, the flame retardant performance of the surface of this wire is improved, and it can assist in improving the high temperature resistance of this wire.
