Problems solved by technology

[0003] Most cables in the prior art use externally coated insulating materials, and metal materials are used as the inner core of the conductor. Due to the low flexibility of the metal material, it is easy to break, resulting in poor tensile strength of the cable. When subjected to a large tensile force, easy to break damage

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0030] Cables in the prior art generally include: an insulating outer layer and a conductor inner core. The conductor inner core is the main carrier for power transmission of the cable and is usually made of metal materials such as copper and aluminum. Due to the low flexibility of the metal material, it is easy to break when subjected to a large tensile force. Therefore, in some special applications, for example, when the cable needs to be pulled, the cable with a conductor inner core made of a metal material cannot meet the requirements.

[0031] Therefore, an embodiment of the present invention provides a tensile cable, which uses a twisted metal wire and a PET wire to make a conductor inner core, which effec...

Abstract

The invention discloses a tensile cable and a method for manufacturing the same, and belongs to the technical field of cables and wires. The tensile cable comprises an insulating outer layer and a conductor inner core. The insulating outer layer covers the conductor inner core, the conductor inner core is a stranded wire, and a plurality of metal wires and at least one PET (polyethylene terephthalate) wire are stranded to form the stranded wire. The tensile cable and the method have the advantages that the tensile strength of the tensile cable can be obviously improved on the premise that the conductivity of the tensile cable is guaranteed, and the tensile cable cannot be broken or damaged easily and is firm and durable.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a tensile cable and a manufacturing method thereof. Background technique [0002] Cables are usually twisted by several or groups of wires (at least two in each group), similar to ropes, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with Highly insulating overlay. Common cables, such as power cables, control cables, signal cables, etc., are composed of single-strand or multi-strand wires and insulation layers, and can be used to connect circuits, electrical appliances, etc. The cable has the characteristics of internal electrification and external insulation. Cables in a broad sense usually include wires. [0003] Most cables in the prior art use externally coated insulating materials, and metal materials are used as the inner core of the conductor. Due to the low flexibility of the metal mate...
