Description
Technical field
The utility model relates to wire and cable fields, and in particular to a kind of cable.
Background technique
Cable is widely used in every field as a kind of electric power, information transmission equipment.Copper core cable under the prior art
Due to the influence being self-possessed with working environment, it is easy to happen creep, work under high temperature environment makes cable be easy weak pine for a long time
It is dynamic to be even broken, cause safety problem.
Utility model content
The utility model aim is to be to provide a kind of fireproof high-temperature resistant waterproof creep resistant cable, to solve above-mentioned at least one
A technical problem.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of fireproof high-temperature resistant waterproof creep resistant cable, including a cable, the cable include sheath and are embedded in described
At least four cables core that beam in sheath is combined, which is characterized in that the sheath is made of Ceramic silicon rubber
Sheath, the interior netted reinforcement sandwich layer being woven into equipped with a seizing wire of the sheath；
The cable core includes conductor and the insulating layer that is wrapped in outside conductor, and the insulating layer is made of Ceramic silicon rubber
Insulating layer, wrap up outside the insulating layer by glass braid at protective layer.
The utility model optimizes the structure and material of traditional cable, reinforces sandwich layer and in electricity by being arranged in sheath
Protective layer is set outside cable core to improve the creep resistance of cable.Sheath is made of Ceramic silicon rubber, and sheath uses ceramic
Silicon rubber, the residue after burning are ceramic shell, can be at a temperature of 950 DEG C -1000 DEG C, by fiery 90min, effective protection
Cable.The netted reinforcement sandwich layer that seizing wire is woven into is had additional in sheath, reticular structure will not influence the flexible of cable
Property, at the same be greatly improved again the tension of cable, resistance to compression, anti-torsion performance, it is not easy to be broken.Metal mesh can also play screen
Cover the jamproof effect of signal.Outside the insulating layer of cable core wrap up by glass braid at protective layer, improve cable core
Intensity, it is not easy to distort.
The conductor is closed using wire bundle.
The wire is preferably silver-gilt copper wire or tinned copper wire.High temperature can accelerate metal material that creep occurs, compared to
Bare copper wire, silver-gilt copper wire or tinned copper wire have better thermal conductivity and high temperature oxidation resistance, it is not easy to creep occur.
Moisture-proof powder is inserted between the wire.Prevent working environment excessively moist.
When stranding, water blocking yarn is filled between the cable core, winds layer of glass band, the glass outside the cable core
One layer of water blocking tape is wound outside glass fiber band.Water blocking yarn can prevent cable core from intaking, and glass fiber tape plays the work of partiting thermal insulation
With water blocking tape is wrapped in outside glass fiber tape, prevents insulation function from failing.Moisture-proof powder, water blocking yarn, water blocking tape are on the market may be used
With the common materials bought.
As a preferred embodiment, wrap up outside the glass fiber tape another layer by glass braid at protective layer.Increase
It is powered on the intensity of cable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1, a kind of fireproof high-temperature resistant waterproof creep resistant cable, including a cable, cable include sheath 1 and are embedded in
At least four cables core 2 that beam in sheath 1 is combined, sheath 1 are the sheaths made of Ceramic silicon rubber, in sheath 1
The netted reinforcement sandwich layer 11 being woven into equipped with a seizing wire；Cable core 2 includes conductor 21 and the insulation being wrapped in outside conductor
Layer 22, insulating layer 22 are insulating layers made of Ceramic silicon rubber, wrapped up outside insulating layer 22 by glass braid at protective layer
23。
The utility model passes through the structure and material of optimization traditional cable, to improve the creep resistance of cable.Sheath 1 is adopted
It is made of Ceramic silicon rubber, environmental protection simultaneously has excellent insulating properties and fire resistance, while having and having preferable flexibility.It is protecting
The netted reinforcement sandwich layer 11 that seizing wire is woven into is had additional in set 1, reticular structure will not influence the flexibility of cable, simultaneously
Be greatly improved again the tension of cable, resistance to compression, anti-torsion performance, it is not easy to be broken.Metal mesh can also play shielded signal
Jamproof effect.Outside the insulating layer 22 of cable core 2 wrap up by glass braid at protective layer 23, hot-face insulation it is same
When, also improve the intensity of cable core 2, it is not easy to be broken.
Conductor 21 is closed using wire bundle.Wire is preferably silver-gilt copper wire or tinned copper wire.High temperature can accelerate gold
Belong to material and creep occurs, compared to bare copper wire, silver-gilt copper wire or tinned copper wire have better thermal conductivity and high temperature oxidation resistance,
Creep is less likely to occur.Moisture-proof powder 3 is inserted between wire.Prevent working environment excessively moist.When stranding, between cable core 2
Water blocking yarn 4 is filled, layer of glass band 5 is wound outside cable core 2, winds one layer of water blocking tape 6 outside glass fiber tape 5.Water blocking yarn 4
It can prevent cable core from intaking, glass fiber tape 5 plays the role of partiting thermal insulation, and water blocking tape 6 is wrapped in outside glass fiber tape 5,
Prevent insulation function from failing.Moisture-proof powder, water blocking yarn, water blocking tape are the common materials that can be bought on the market.As a kind of excellent
Select scheme, wrapped up outside glass fiber tape 5 another layer by glass braid at protective layer 7.Increase the intensity of cable.
