Abstract
The utility model discloses a flexible mineral insulation cable, include the conductor and be located the outer copper sheath of conductor, the conductor is circular copper stranded conductor, and single the equal cladding in the conductor outside has an inorganic mineral insulation layer, glass fiber tape around the package in the outside on inorganic mineral insulation layer, it has the glass silk to restrict to pack between the inorganic mineral insulation layer and glass fiber tape and inorganic mineral insulation layer, is provided with the supervision sinle silk between glass fiber tape and copper sheath. This practicality enough improves the compliance and the resistant electricity stability of conductor.
Description
Technical field
The utility model relates to cable, more specifically to a kind of flexible mineral insulation cable.
Background technology
Copper core copper sheath magnesium oxide insulating cable, is called for short mineral insulated cable or fireproof cable.Shown in Figure 2, it adopts the copper rod of high conductivity to make conductor, and inorganic matter magnesium oxide makes insulating barrier, and sheath made by seamless copper pipe.Cable is used through vertical pulling, dish draws, the special process such as annealing is made modern architecture wiring cable and special industry (metallurgy, chemical industry, oil etc.).Mineral insulated cable is subject to factory building, equipment, the restriction of raw material present situation in process of production, cable can only short section of production, can not realize the delivery of large length, need transition joint annex to connect when line arrangement, and need butt joint place electric property to do special processing, cost is higher.Drawing copper tubes technique makes single continuous length limited, 35mm
2and be single-core cable, core rod type solid copper conductor above, and very hard, make its maximum cross-section be generally 400mm
2.Installation procedure is many, and is unfavorable for the equilibrium of each core electric parameter.Magnesium oxide powder serves as insulating barrier, and easily produce became uneven phenomenon, technique slightly mistake just can puncture, and rated voltage is up to 450/750V.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible mineral insulation cable, to improve the flexibility of conductor and resistance to electrical stability.
A kind of flexible mineral insulation cable described in the utility model, comprise conductor and be positioned at the copper sheath outside conductor, described conductor is circular copper stranded conductor, inorganic mineral insulation layer is all coated with outside single conductor, the wrapped outside at inorganic mineral insulation layer of glass fiber tape, between inorganic mineral insulation layer and between glass fiber tape and inorganic mineral insulation layer, be filled with glass-silk rope, between glass fiber tape and copper sheath, be provided with supervision core.
Flexible mineral insulation cable described in the utility model, conductor is adjusted to stranded conductor by existing copper bar drawing solid conductor, improves the flexibility of conductor.Insulation is adjusted to inorganic mineral insulation layer (being commonly called as artificial mica synthesis band) by magnesium oxide insulated layer, and this insulating barrier is proof gold mica tape, no longer forms with extruded insulation material compound, thus gets rid of the generation of carbon granules, improves resistance to electrical stability.Compound glass fabric strip eliminates the generation of carbon granules, further increases resistance to electrical stability, use monitor core on-line monitoring by with fire linking control system in fire protection control room, carry out on-line checkingi cable whether safe and stable operation.This flexible mineral insulation cable, have employed the traditional cable such as twisted wire, stranding structure, makes cable more soft, simultaneously owing to not needing special-purpose terminal joint, not only reduces joint cost, more convenient install and lays.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing mineral insulated cable.
Embodiment
In order to explain the technical solution of the utility model further, below in conjunction with accompanying drawing, the utility model is elaborated.
Shown in Figure 1, this flexible mineral insulation cable, comprise conductor 1 and be positioned at the copper sheath 6 outside conductor 1, described conductor 1 is circular copper stranded conductor, inorganic mineral insulation layer 2 is all coated with outside single conductor 1, the wrapped outside at inorganic mineral insulation layer 2 of glass fiber tape 4, is filled with glass-silk rope 3 between inorganic mineral insulation layer 2 and between glass fiber tape 4 and inorganic mineral insulation layer 2, is provided with and monitors core 5 between glass fiber tape 4 and copper sheath 6.
