Multi-core parallel cable and manufacturing method therefor

Abstract

The invention relates to a multi-core parallel cable and a manufacturing method therefor, and belongs to the technical field of power cables. The technical scheme of the invention are that a first main power cable core, a second main power cable core and a ground power cable core are closely arranged in parallel; the ground power cable core is disposed between the first and second main power cable cores; the first main power cable core, the second main power cable core and the ground power cable core form a power cable core; the power cable core is uniformly wrapped by a protection layer (5) in an extruding manner, thereby forming a multi-core parallel cable. The flat overall structure design of the cable enable the cable to be installed and laid in a neat and ordered manner, and prevents the crossing and messing of cables from causing the laying of other cables to be inconvenient. Meanwhile, the main ground lines are arranged at intervals, thereby guaranteeing the electrical safety of the insulating cable core, and avoiding an electrical fault caused by the adjacent cable cores with the thin insulating layers. An 8-like shape design enables the thickness of the external protection layer to be more uniform and consistent, and reduces the manufacture cost.

Description

technical field [0001] The invention relates to a multi-core parallel cable and a manufacturing method thereof, belonging to the technical field of power cables. Background technique [0002] In the fixed laying and wiring of urban buildings and industrial fixed laying and wiring, power cables are conventionally laid in cable trays and trays; During the process, intersecting and confusing lines will bring inconvenience to future maintenance and inspection. At the same time, chaotic laying will also bring safety hazards to the continuous use of cables. Contents of the invention [0003] The purpose of the present invention is to provide a multi-core parallel cable and its manufacturing method. Under the premise of ensuring the stability of the core structure of the main wire and the ground wire, the insulation outer sheath of the main wire and the ground wire is consistent, and the production cost of the cable is reduced; the parallel structure of the cable The design can ...
