Abstract
The utility model discloses a shielding control cable, comprising a plurality of cable cores; each cable core comprises a wire core set and an insulating layer, wherein the insulating layer covers the wire core set; the external part of the cable cores is provided with an inside liner; packing materials are filled among the plurality of cable cores and the inside liner; the external part of the inside liner is provided with a steel band armor layer which is covered by an oversheath. According to the mode, the shielding control cable can raise cable shielding property, has good flame retardation and insulation effect and possesses a simple structure.
Description
Technical field
The utility model relates to control cable field, particularly relates to a kind of shielding control cable.
Background technology
Shielding control cable is used for the occasion that ac rated voltage 450/750V and following control, monitoring loop and protection circuit etc. need shielding; as the connection between all kinds of electrical instrumentations and the automation equipment; play the various electric energy of transmission or signal effect, make whole electric system obtain safe and reliable operation.
Shielded type cable namely refers to braiding or wrapped one deck screen outside cable insulation, in order to reduce the interference of electric current in the outer bound pair insulating barrier, also reduce simultaneously the magnetic field influence to external world that electric current produces in the insulating barrier, be applicable to the jamming-proof various electrical equipment that requires of various alternating current-direct currents, as circuit connection of instrument, telecommunications, computer network control system, power equipment and automation equipment thereof etc.The deriving of electric wire/new product mainly be in response to occasion, application requirements is different and the convenience of equipment and reduce the requirement of equipment cost etc., and adopt new material, special material or change product structure or improve technological requirement and produce.Under some special occasion, cable needs anti-flammability and insulating properties preferably, and existing cable can not satisfy user demand.
