Problems solved by technology
There are disadvantages in the use of general-purpose cables. Due to the current skin effect, the effective utilization efficiency of the conductor cross-section of large-size circular cables is very low, and the outer diameter of multi-core cables is large, which is not conducive to the limited space of mobile equipment; flat cables are individually insulated with large-size round conductors. The core wires are arranged at intervals, in addition to the low utilization rate of the conductor cross-section, at the same time, the size is large, the number of layers is large, and bending is difficult, which is not conducive to heat dissipation

Abstract
The invention relates to the technical field of strong-current flat cables, and specifically relates to an anti-nuclear-electromagnetic large-current flexible flat cable which comprises a plurality ofinsulating wire cores and sheaths arranged outside the insulating wire cores. Each insulating wire core comprises a conductor, an insulating layer and a shielding layer which are arranged from insideto outside, the insulating layer is extruded outside the conductor, and the conductor is a plurality of adjacent branch conductors which are horizontally arranged. The flat cable provided by the invention can meet the requirements of mobile high-current transmission and flexible bending of the cable in a nuclear electromagnetic environment.
Description
technical field [0001] The invention relates to the technical field of strong electric flat cables, in particular to an anti-nuclear electromagnetic large current flexible flat cable. Background technique [0002] With the large-scale and high-power development trend of anti-nuclear magnetic electrical equipment, higher and higher requirements are put forward for cables. The existing cables at home and abroad mainly focus on the weak current of instrumentation, control, communication, and electronic transmission that meet the anti-nuclear magnetic requirements. Cables, there is no anti-nuclear electromagnetic flexible power cable suitable for equipment mobile power transmission in harsh environments. There are disadvantages in the use of general-purpose cables. The effective utilization efficiency of large-size round cables is very low due to the current skin effect, and the outer diameter of multi-core cables is large, which is not conducive to the limited space of mobile e...
