Problems solved by technology
The electrical connection and signal control in the intelligent high-voltage switchgear generally requires several sets of cables to complete, a set of high-voltage cables for electrical transmission connections, a set of control cables for equipment actions and signal connections, etc., so it is necessary to lay multiple cables. As a result, the wiring in the cabinet is easy to cross, there are many lines, and the wiring is messy, which is not conducive to later inspection and maintenance.

Abstract
The invention discloses ahigh-voltage switch cabinet cable. The cabinet cable includes an outer sheath, Inner sheath, a heat insulation layer, shield layer, an outer conductorand an inner conductor and wire core, the outer conductor is arranged between the outer sheath and the insulating layer, the shielding layer is arranged between the heat insulation layer and the inner sheath, The inner conductor is arranged at the central position of the inner sheath, the wire cores are respectively arranged on the outer periphery of the inner conductor and located in the inner sheath, and the gap betweenthe wire core and the inner conductor is filled with filling material, wherein the outer conductor adopts a hollow cylinder structure, and the inner conductor adopts a solid cylinder structure. The high-voltage switch cabinet cable provided by the invention not only transmits electric power, but also transmits control signals in the cabinet, so that the intelligent functions and effects of the intelligent high-voltage switch cabinet are fully embodied, the functions of remote control and unattended operation are realized, and the high-voltage switch cabinet cable has good social and economicbenefits, and is easy to be widely popularized and applied.
Description
technical field [0001] The invention relates to the field of high-voltage switch cabinets, in particular to a cable for high-voltage switch cabinets. Background technique [0002] At present, intelligent high-voltage switchgear requires functions such as electrical transmission and transformation, transmission of closing and opening control command signals, execution of closing and opening command signals, and real-time monitoring of the operating status of high-voltage switchgear. The electrical connection and signal control in the intelligent high-voltage switchgear generally requires several sets of cables to complete, a set of high-voltage cables for electrical transmission connections, a set of control cables for equipment actions and signal connections, etc., so it is necessary to lay multiple cables. As a result, the wiring in the cabinet is easy to cross, there are many lines, and the wiring is messy, which is not conducive to later inspection and maintenance. Cont...
