Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] see Figure 1-3 , the present invention provides a technical solution: a multi-core control cable, including a cable body 1, an inner sleeve 2, and an inorganic insulating layer 4. The interior of the cable body 1 is provided with a filler 102, and the filler 102 is embedded in the cable In the main body 1, the inner layer of the filler 102 is provided with a steel wire protective layer 103, and the steel wire protective layer 103 is closely attached to...

The invention discloses a multi-core control cable, comprising a cable body, an inner sheath and an inorganic insulating layer. A filler is arranged in the cable body and is embedded in the cable body; an inner layer of the filler is a wire protection layer; the wire protection layer is in tight fit with the filler; an aluminum conductor is arranged in the inner sheath and is embedded in the innersheath. The multi-core control cable has the advantages that asbestos is a material of good electrical insulation having good tensile strength and good tolerance to chemical and thermal erosion, theproblem is effectively solved that corrosive damage is caused due to the fact that an existing cable is easily subject to different ambient acidity or alkalinity levels, cable filling is achieved, theservice life of the cable is extended, and application quality of the cable is improved accordingly.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a multi-core control cable. Background technique [0002] Cable (electric cable; power cable): usually composed of several or several groups of wires, made of one or more mutually insulated conductors and an outer insulating layer, to transmit power or information from one place to another of wires. A rope-like cable that is usually twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation overlay. The cable has the characteristics of internal electrification and external insulation. 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...
