Abstract
The utility model discloses a four-core monitoring combined cable comprising a plurality of conductors, wherein each conductor is coated with a cross-linked polyethylene insulation layer to form an insulated wire core, the insulated wire cores are twisted into a bundle to form a cable core, the center of the cable core is provided with a rubber tube, a silicon rubber elastic layer and a ceramic silicon rubber refractory layer are sequentially extrusion-molded outside the cable core, the ceramic silicon rubber refractory layer is internally provided with surveillance core wire conductors, each surveillance core wire conductor is sequentially coated with a fireproof layer and a silicon rubber insulation layer, the fireproof layer is formed by wrapping a high-temperature-resistance polyester tape, and an isolation layer and a low-smoke halogen-free polyolefin sheath layer are arranged outside the ceramic silicon rubber refractory layer. The four-core monitoring combined cable is reasonable in structure design, the refractory reliability is increased and the production complexity is reduced due to the design of the ceramic silicon rubber refractory layer, a protective layer and the like, the four-core monitoring combined cable has the functions of signal transmission and monitoring, the using requirements of users are satisfied, and multiple functions are achieved.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of four-core type monitoring combination cable.
Background technology:
Fire-resistant control flexible cable is applicable to that mainly various fire hazards are bigger, the electrical equipment that security against fire importance is higher and control system.
Traditional fireproof control cable manufacture craft mainly adopts the wrapped mica tape of conductor as flame retardant coating, thereby play fire-resistant effect, but because mica is more crisp, wrapped or when changing over to down to operation, the phenomenon that mica comes off may appear, if mica comes off seriously, undoubtedly in use, its fire resistance can be had a greatly reduced quality, fail safe can not be protected, and control cable general core number is all more, all needs wrappedly on the every conductor, produces trouble.
In addition, traditional fireproof control cable function singleness can not play the effect of supervision, therefore, can not satisfy the real work demand.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of four-core type monitoring combination cable, according to its use occasion environment its structure is designed, its production technology is simple, fire resistance is safe and reliable, has the effect of transmission signal, supervision, satisfies user's instructions for use.
The technical solution of the utility model is as follows:
Four-core type monitoring combination cable, comprise several conductors, it is characterized in that: described several conductors are wrapped with crosslinked polyetylene insulated layer and constitute insulated wire cores, the mutual stranded bunchy of insulated wire cores constitutes cable core, the cable core center is provided with rubber tube, cable core outward successively extrusion moulding silicon rubber elastic layer, ceramic silicon rubber flame retardant coating are arranged, be provided with the pilot wire core conductor in the ceramic silicon rubber flame retardant coating, pilot wire core conductor outer fireprotection layer, the silicone rubber insulation layer of the wrapped formation of high temperature resistance polyester band successively, ceramic silicon rubber flame retardant coating is provided with separator, low-smoke halogen-free polyolefin restrictive coating outward.
Described four-core type monitoring combination cable, it is characterized in that: described separator has the overlapping wrapped formation of high flame retardant fabric strip, and the wrapped rate of putting up is not less than 30%.
The utility model has the advantages that:
1, changes traditional fire-resisting cable with the technology of wrapped mica tape as flame retardant coating, change into and extrude pottery silicon rubber as flame retardant coating, increase fire-resistant reliability and reduce the production complexity; Behind the cable stranding, do not fill, not wrapped, cable roundness height.
2, extrude pottery silicon rubber flame retardant coating after, wrapped one deck high flame retardant band more both uses as separator, also plays fire retardation, makes the flame-retardant performance of cable better.
3, will monitor core and control conductor combine, realize multi-functional effect.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Four-core type monitoring combination cable, comprise several conductors 1, several conductors 1 are wrapped with crosslinked polyetylene insulated layer 2 and constitute insulated wire cores, the mutual stranded bunchy of insulated wire cores constitutes cable core, the cable core center is provided with rubber tube 3, cable core outward successively extrusion moulding silicon rubber elastic layer 4, ceramic silicon rubber flame retardant coating 5 are arranged, be provided with pilot wire core conductor 6 in the ceramic silicon rubber flame retardant coating 5, pilot wire core conductor 6 outer fireprotection layer 7, the silicone rubber insulation layers 8 of the wrapped formation of high temperature resistance polyester band successively, ceramic silicon rubber flame retardant coating 5 outer separator 9, the low-smoke halogen-free polyolefin restrictive coatings 10 of being provided with.
