The invention discloses a high temperature and high voltage resisting cable which comprises a cable core. The cable bore is wrapped by a plurality of high temperature resisting layers with the sections in a sector shape in sequence, gaps exist between the high temperature resisting layers, a plurality of steel wires are arranged in the gap between every two adjacent high temperature resisting layers, and the high temperature resisting layers are wrapped by a sheath. The high temperature and high voltage resisting cable is simple in structure, the cable core is wrapped by the high temperature resisting layers with the sections in the sector shape, the steel wires are arranged in the gaps between the high temperature resisting layers, and thus the overall high temperature and high voltage resisting performance of the cable is effectively improved. Furthermore, the technology is simple, and cost is low.
Description
technical field [0001] The invention relates to the field of cables, in particular to a high temperature and high pressure resistant cable. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] For cables working in high temperature and high pressure environments, the requirements for their internal high temperature and high pressure performance are relatively high. In order to achieve the purpose of high temperature resistance and high pressure, but the structure is complicated, the process is complicated, and the cost is high. The existing cable sheath material has disadvantages such as poor aging resistance. Conte...
