Description
Technical field
The utility model relates to a kind of technical field of electric wires and cables, more particularly to a kind of fire resistant sheathed cable.
Background technique
Existing wire cable insulating, sheath material almost all are organic material, or part includes organic material, including poly-
Including material including tetrafluoroethene, fusing point is no more than 400 DEG C, uses not more than 350 DEG C of temperature.So, metallurgy, electricity
The high-temperature area of the other industries such as heating device, heating tube, baking oven, electroheat pair, temperature sensor, electric furnace, stove, traditional electric wire
It is unable to satisfy high temperature resistant requirement.
Utility model content
Aiming at the shortcomings existing in the above problems, the utility model provides a kind of fire resistant sheathed cable, makes it
It can be used for a long time in the environment no more than 1000 DEG C, completely cut off splash and flame completely and be able to maintain its knot under continuous high temperature exposure
Structure.
To solve the above-mentioned problems, the utility model provides a kind of fire resistant sheathed cable, wherein including sheathed cable sheet
Body, the sheathed cable ontology include fiber jacket and oxygen-free copper core, and the oxygen-free copper core includes the first nothing being set side by side
Oxygen copper core body and the second oxygen-free copper core, the fibre sleeving are coated on the first oxygen-free copper core and the second anaerobic copper core
The outside of body, the outside of the first oxygen-free copper core are successively coated with nickel layer, mica tape and fibrous insulation, and described
One oxygen-free copper core is identical with the second oxygen-free copper core.
Preferably, the fiber jacket is resurrection glass fibre sheath.
Preferably, the fibrous insulation is resurrection glass fibre insulating materials.
Preferably, the mica tape is two-way wrapped composite structure.
Compared with prior art, the utility model has the advantage that
The utility model uses inorganic material as insulation, completely using oxygen-free copper as conductor with synthetic mica tape (fusing point
1375 DEG C) and resurrection glass fibre (softening point is close to 1700 DEG C) be predominating insulation, product, which can be used for a long time, not to be surpassed
It crosses in 1000 DEG C of environment, completely cuts off splash and flame completely and be able to maintain its structure, but need to avoid hydrogen under continuous high temperature exposure
Fluoric acid, hot concentrated phosphoric acid have certain Corrosion Protection to other chemical substances.
Detailed description of the invention
Fig. 1 is the embodiments of the present invention structural schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing with example
The utility model is described in further detail, but example is not as the restriction to the utility model.
As shown in Figure 1, the embodiments of the present invention include sheathed cable ontology 1, sheathed cable ontology 1 includes fiber jacket 4
With oxygen-free copper core, oxygen-free copper core includes the first oxygen-free copper core 2 and the second oxygen-free copper core 3 being set side by side, fibre sleeving 4
It is coated on the outside of the first oxygen-free copper core 2 and the second oxygen-free copper core 3, the outside of the first oxygen-free copper core 2 is successively coated with
Nickel layer 5, mica tape 6 and fibrous insulation 7, the first oxygen-free copper core 2 are identical with 3 structure of the second oxygen-free copper core.
Fiber jacket 4 is resurrection glass fibre sheath.
Fibrous insulation 7 is resurrection glass fibre insulating materials.
Mica tape 6 is two-way wrapped composite structure.
Small dimension sheathed cable of the present embodiment for the transmission of the signals such as electroheat pair, since wire diameter is thinner, in high temperature
Under the conditions of use, nickel copper-clad conductor (nickel copper-clad be line cable industry conventional products) can be used.
Resurrection glass fibre product weaves thickness can be adjustable in 1mm--5mm range, is completely suitable for the production of different size
The requirement of product insulation thickness.
The utility model indicates that 3 cores or more can also be extended to according to actual needs with two cores.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
