High capacity rectangular flexible cable and preparation technology thereof

Abstract

The invention discloses a high capacity rectangular flexible cable and a preparation technology thereof. The preparation technology of the high capacity rectangular flexible cable is characterized in that the lamination copper bar is superposed with 2 layers or more than 2 layers copper bar, and carrys out by adopting approximate common round cable pay-off equipment to pay-off, a conductor outer layer formed by the lamination copper bar is an insulating layer, the insulating layer is extruded by a cable extrusion machine with a rectangular extruding mold, and the cross section of the high capacity rectangular flexible cable is rectangular or approximately rectangular. The high capacity rectangular flexible cable has the advantages that the capacity is higher, and the current carrying capacity is larger: the cross section of the cable is rectangular, if the cross section is same, the rectangular cable has larger electric current than that of the round cable; the bending radius is smaller: the bending radius is smaller than that of the round cable with the same cross section; the high capacity rectangular flexible cable is convenient to install: manual installation requires smaller space, and special equipment is not required in installation; the high capacity rectangular flexible cable is more convenient to connect, a terminal is not required to install, and installation time is saved; and the tensile strength is extremely high: because the rectangular cable conductor uses the copper bar, and the strain distribution on the width of the cable is uniform.

Description

Technical field: [0001] The invention is a high-capacity rectangular flexible cable and its preparation process. The product adopts an innovative process to design a traditional circular structure cable into a rectangular structure, thereby bringing about a great improvement in performance, a higher current carrying capacity, and a smaller bending radius. In terms of high-capacity current transmission, it can completely replace large cross-section round cables. It is widely used in the soft connection between transformers, power distribution cabinets and equipment, as well as high current transmission in energy equipment and transportation fields such as aircraft, rail vehicles, and ships. Background technique: [0002] On the one hand, because copper is a non-renewable resource, with the development of society, the amount of copper used for its superior electrical and mechanical properties is increasing, which leads to an increase in the price of copper, whether it is from achie...

Problems solved by technology

[0002] On the one hand, because copper is a non-renewable resource, with the development of society, copper is used more and more due to its superior electrical and mechanical properties, which leads to an increase in copper prices, whether it is to achieve the best use of resources or from It is the best solution to consider increasing the ampacity of cables per unit area in terms of cost reduction. On the other hand, the wires and cables used in the domestic and foreign markets are mainly circular in shape. The cables of this structure have the same insulating material. Under the circumstances, if the current to be transmitted is larger, the section of the cable is required to be larger, which not only causes a waste of resources, but also has problems such as the larger the section, the larger the bending radius of the cable, and the inconvenience of installation.
