Special low-inductance high-voltage coaxial cable

Abstract

The invention relates to the technical field of cables, and discloses a special low-inductance high-voltage coaxial cable which comprises a cable body, the cable body comprises an inner core sleeve, a dielectric layer, an inner braid layer, an outer braid layer and an outer sheath, the inner core sleeve is fixedly arranged on the inner side wall of the inner braid layer, the dielectric layer is fixedly arranged between the inner braid layer and the outer braid layer, and the outer sheath is fixedly arranged between the inner braid layer and the outer braid layer. The outer sheath is fixedly sleeved on the outer side wall of the outer braid layer, the dielectric layer is made of polytetrafluoroethylene, and the inner braid layer and the outer braid layer are both formed by braiding silver-plated copper wires. The special low-inductance high-voltage coaxial cable is conductive through double-layer weaving, can meet the use requirements of direct-current high pulse voltage or alternating-current high voltage, can meet the use requirements of low-inductance performance indexes and the like in a high-frequency range, and is good in coaxial performance, excellent in anti-electromagnetic effect, good in anti-stamping performance and suitable for special military use.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a special low-inductance high-voltage coaxial cable. Background technique [0002] A cable refers to a wire made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits power or information from one place to another. With the harsh application environment of the cable, the performance requirements of the cable are also More stringent, like the interior of special military equipment, it is required to meet the use requirements of DC high pulse voltage or AC high voltage, and to meet the performance indicators of low inductance in the high frequency range. [0003] At present, the signal current and the return flow on the coaxial cable can be equivalent to the geometric coincidence, and its area is 0, so that the external electromagnetic interference can be well overcome. Therefore, the coaxial cable is often used as a special military ...
