Anti-corrosion stretch-proof industrial control cable

Abstract

The invention discloses an anti-corrosion stretch-proof industrial control cable, comprising reinforcing ribs, wherein stranded conductors are spirally wound outside the reinforcing ribs; the outsides of the conductors are wrapped with shielding layers; gaps between the conductors and the shielding layers are filled with a filler; the outsides of the shielding layers are covered with a stretch-proof metal net; the outside of the stretch-proof metal net is wrapped with an anti-corrosion layer; a fire-retardant layer is arranged outside the anti-corrosion layer; a stretch-proof metal strip is arranged outside the fire-retardant layer. The control cable is characterized in that reinforcing ribs, the stretch-proof metal net, and the stretch-proof metal strip arranged along a cable length direction are arranged, the stretch-proof performance of the cable and the structure strength are greatly improved by spirally winding the conductors, and the anti-corrosion performance of the cable is improved by the anti-corrosion layer, the fire-retardant layer and the protection layer; besides the control cable has the advantages of reasonable structure design, good anti-corrosion and stretch-proof effect and long service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-corrosion and tensile-resistant industrial control cable. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts ; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables, and in the narrow sense, cables refer to insulated cables. It can be d...

Problems solved by technology

[0003] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, even in high-end fields including space and ocean, cables will be used. With the development of social economy, cable varieties are constantly updated and improved. The requirements have also increased. The existing cables cannot meet the needs of the industry due to material and structural problems. In some highly corrosive environments, ordinary cables cannot work normally, and the internal structure of the cable is easy to appear. In the case of corrosion, at the same time, after the cable is installed, transported and used for a long time, its tensile performance cannot meet the current needs. Therefore, we have designed a corrosion-resistant and tensile-resistant industrial control cable to solve the above problems
