Abstract
The invention relates to a mineral insulated ultra-soft fireproof cable, which mainly comprises cable cores, wherein each cable core is formed by successively nesting and wrapping a copper core conductor, a mica insulating layer and a waterproof layer from inside to outside; a corrugated copper sheath is arranged at the outer side of each waterproof layer; and an outer sheath is arranged at the outer side of each corrugated copper sheath. The mineral insulated ultra-soft fireproof cable plays a heat-resistant role, and simultaneously plays a buffering role between the cable cores and between the cable cores and the corrugated copper sheaths; the abrasive resistance of the cable is increased; abrasion caused by the cable in the long-term stretching or moving process is avoided; and the service life of the cable is prolonged.
Description
Technical field
The present invention relates to technical field of electric wires and cables, specifically a kind of mineral insulation supersoft fireproof cable.
Background technology
Mineral insulation supersoft fireproof cable is a kind of outer employing low smoke and zero halogen oversheath, centre adopts seamless embossing copper pipe sheath, synthetic mica tape is wrapped makes insulating material, and conductor adopts the novel cable of the 5th class conductor composition.Copper core copper sheath cable is widely used in the danger such as nuclear power station, metallurgy, chemical industry, mine, kiln processed, severe, hot environment.Also morely in recent years the places such as skyscraper, airport, harbour, underground railway are applied to, due to the particularity of environment for use, in use, high-frequency movement and bending cable may be needed, be easy to make cable produce wearing and tearing in bending process, thus cause shorten the useful life of cable, time serious, also can produce potential safety hazard, use safety coefficient is low, and useful life is short.
Summary of the invention
In order to the defect of above-mentioned technology, the present invention proposes the good and a kind of mineral insulation supersoft fireproof cable of long service life of easy mobile resistance to wear.
Technical solution of the present invention is:
A kind of mineral insulation supersoft fireproof cable, mainly comprise cable core, the equal from-inner-to-outer of described cable core is carried out successively nested parcel by copper core conductor, mica insulation layer, water blocking layer and is formed successively, be provided with embossing copper sheath in the outside of described water blocking layer, be provided with oversheath in the outside of described embossing copper sheath layer.
The quantity of described cable core is one or many.
Described copper core conductor is the 5th class conductor.
High temperature packing rope is filled with between cable core and embossing copper sheath layer.The innovation product structure is simple, makes cable also can have stronger tensile force under severe conditions, ensures the quality of cable, and this cable conductor adopts the 5th class conductor soft, is applicable to moving frequently.
Structure of the present invention is simple, makes cable also can have stronger tensile force under severe conditions, ensures the quality of cable, and is applicable to moving frequently.
The invention has the beneficial effects as follows:
The present invention also has additional waterstop in the outside of insulating barrier, enhance the moisture effect of cable, cable core and be filled with high temperature filler between restrictive coating, serve high temperature resistant effect, play between cable core simultaneously, cushioning effect between cable core and embossing copper sheath, outside embossing copper sheath, add low smoke and zero halogen oversheath, cable surface is made to define a wearing layer, increase the resistance to wear of cable, avoid cable to stretch for a long time or movement process in the wearing and tearing that cause, the useful life of prolongation cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As shown in Figure 1, a kind of mineral insulation supersoft fireproof cable, mainly comprise cable core, the equal from-inner-to-outer of described cable core is carried out successively nested parcel by copper core conductor 1, mica insulation layer 2, water blocking layer 3 and is formed successively, be provided with embossing copper sheath 4 in the outside of described water blocking layer 3, be provided with oversheath 5 in the outside of described embossing copper sheath layer 4.
The quantity of described cable core is one or many.
Described copper core conductor 1 is the 5th class conductor.High temperature packing rope is filled with between cable core and embossing copper sheath layer.The innovation product structure is simple, makes cable also can have stronger tensile force under severe conditions, ensures the quality of cable, and this cable conductor adopts the 5th class conductor soft, is applicable to moving frequently.
Structure of the present invention is simple, makes cable also can have stronger tensile force under severe conditions, ensures the quality of cable, and is applicable to moving frequently.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed the present invention.Application claims protection range is defined by appending claims and equivalent thereof.
