High temperature resistant flexible power control composite cable

Abstract

The invention discloses a high temperature resistant flexible power control composite cable. The high temperature resistant flexible power control composite cable comprises a control signal cable and an electric cable; the control signal cable comprises multiple control signal units and a polyester belt layer which is used for coating the multiple control signal units; the electric cable comprises multiple electric power transmission units and an inner protective layer, an armor layer and an outer protective layer which are used for sequentially coating the multiple electric power transmission units; the control signal cable is arranged at a gap formed by the multiple electric power transmission units; an inner metal wire weaving shielding layer is composited on the inner wall of the inner protective layer; the outer wall of the outer protective layer is also coated with an outer metal wire weaving protective layer; the outer surface of the polyester belt layer of the control signal cable is also sequentially coated with the metal wire weaving shielding layer and an outer polyester belt protective layer. Due to the adoption of the structure, the high temperature resistant flexible power control composite cable has the advantages of being capable of effectively shielding higher harmonic and electromagnetic interference generated in the running of the electric power transmission units, having no influence on transmission of control signals and having good high temperature resistant performance.

Description

technical field [0001] The invention relates to an integrated cable capable of simultaneously transmitting control signals and electric power, in particular to a high-temperature-resistant flexible electric control integrated cable. Background technique [0002] The structure of the cable generally mainly includes a plurality of power transmission units and an inner sheath, an armor layer and an outer sheath that are sequentially covered outside the multiple power transmission units. The power transmission unit includes a power conductor core and a sequential sheath. The mica tape layer and the power insulation layer covering the core of the power conductor; the structure of the control signal cable generally mainly includes multiple control signal units and the polyester tape layer coated outside the multiple control signal units, each control signal unit There are two control signal conductor cores, and each control signal conductor core is coated with a signal insulating ...

AI Technical Summary

Problems solved by technology

Some electrical equipment will also perform the task of transmitting control signals. Since the high-order harmonics and electromagnetic interference generated during cable operation will interfere with the signal transmission of the control signal cable, the cable and the control signal cable cannot simply be made into a composite cable. To achieve multiple functions with one cable

In addition, for iron and steel smelting occasions, due to the driving of the molten steel in the smelting furnace, the molten steel is easy to splash outwards, and it is easy to fall on the cable, causing damage to the cable. Although there are some high-temperature resistant cable products on the market, the temperature resistance of the cable Grade and flexibility are not up to the customer's requirements
