Abstract
The invention discloses a high-temperature-resistant cable. The high-temperature-resistant cable comprises a metal cable core, a first winding tape, a second winding tape and a sheath, the first winding tape which is an organic silicon tape containing mica granules is spirally wound on the metal cable core to form a first wrapping layer, the second winding tape is wound outside the first winding tape to form a second wrapping layer and is a carbon fiber tape containing anisotropic graphite granules, and the sheath which is a polymer wraps the second winding tape. By the aid of the scheme, two high-temperature-resistant layers are added on the periphery of the metal cable core and consist of the organic silicon tape containing mica and the carbon fiber tape containing the graphite granules respectively, and high temperature resistance of the cable can be improved greatly by the aid of high-temperature-resistant performance of the mica and graphite.
Description
Technical field
The present invention relates to the cable machinery field, relate in particular to a kind of high temperature-resistant cable.
Background technology
The operational environment of cable is very changeable, often runs in the real work at the scene to be arranged in high temperature, and for example ambient temperature reaches the cable in the high-temperature area more than 250 ℃.Under the operational environment of this high temperature, common cable is owing to can't bear working temperature and impaired or hydraulic performance decline, cause signal or electric power transfer fault, cause the fault trip, stoppage in transit of main equipment even damage, have very big hidden danger for the safe handling of main equipment.And can't enter in normal this high-temperature area in service, work has brought very big difficulty to repair and maintenance.Above-mentioned situation is all brought very big harm to safety, the economy of power equipment.
At present high temperature-resistant cable commonly used generally adopts high temperature plastics insulating material composite sheath, about 200 ℃ of heatproofs, and have that useful life is short, conductance is low, antioxygenic property is poor, the contact of electric point is perishable, and easily the shortcoming such as aging can't satisfy instructions for use.
Summary of the invention
The present invention is intended to propose a kind of high temperature-resistant cable, utilizes the exotic materials such as mica and graphite to improve the heat resistance of cable.
According to one embodiment of the invention, a kind of high temperature-resistant cable is proposed, comprising:
The metal cable core;
The first take-up strap, the first take-up strap are spirally wound on and form the first coating layer on the metal cable core, and the first take-up strap is the organic silicon ribbon that comprises mica particles;
The second take-up strap, the second take-up strap are wrapped in outer second coating layer that forms of the first take-up strap, and the second take-up strap is the carbon fiber tape that comprises anisotropic graphite granule;
Overcoat is wrapped in outside the second take-up strap, and overcoat is polymer.
In one embodiment, the metal cable core is copper cable core, aluminium cable core or the aluminium cable core that is coated with copper clad.
In one embodiment, the second take-up strap is bonded to anisotropic graphite granule on the carbon fiber tape by the adhesive through carbonization.
In one embodiment, anisotropic graphite granule is the graphite granule through compacting, and compacted density is 0.35～0.4g/cm
3The diameter of anisotropic graphite granule is 100～150 μ m.Anisotropic graphite granule is flat graphite granule.
Adopt the solution of the present invention, increase two-layer high-temperature-resistant layer in the periphery of metal cable core, the carbon fiber tape by micaceous organic silicon ribbon and graphitiferous particle consists of respectively, utilizes the resistance to elevated temperatures of mica and graphite significantly to promote the heat-resisting ability of cable.
Description of drawings
Fig. 1 has disclosed the structure chart according to the high temperature-resistant cable of one embodiment of the invention.
Fig. 2 has disclosed the sectional structure chart according to the high temperature-resistant cable of one embodiment of the invention.
Embodiment
The present invention is intended to develop a kind of high temperature-resistant cable that possesses following performance requirement:
Heat-resisting quantity: 400 ℃ of long-term work heatproofs; 500 ℃ of limit high temperature; Be difficult for aging.
Physical characteristic: tight parcel, soft, flexible; Anticorrosion; Anti-oxidant; Not flammable (certainly putting out from fire).
Conventional parameter: conductance, dielectric voltage withstand are equal to normal signal, control cable at least.
With reference to illustrated in figures 1 and 2, high temperature-resistant cable of the present invention has following structure.
The core of this high temperature-resistant cable 100 is metal cable cores 102.Metal cable core 102 is copper cable core, aluminium cable core or the aluminium cable core that is coated with copper clad.Be enclosed with the first coating layer 104 in the outside of metal cable core 102.The first coating layer is spirally wound on the metal cable core 102 by the first take-up strap and forms.The first take-up strap is the organic silicon ribbon that comprises mica particles.Mica is a kind of exotic material and has good flame-retarding characteristic.Mica particles is mixed in organic silicon ribbon, utilizes the elasticity of organic silicon ribbon, just can form the coating layer that possesses good physical properties and high-temperature stability.It is the second coating layer 106 outside the first coating layer 104.The second coating layer 106 is wrapped in the first coating layer 104 outer formation by the second take-up strap.The second take-up strap is the carbon fiber tape that comprises anisotropic graphite granule.In one embodiment, anisotropic graphite granule is the graphite granule through compacting, and compacted density is 0.35～0.4g/cm
3The diameter of graphite granule is flat graphite granule between 100～150 μ m.By the adhesive through carbonization this graphite granule is bonded on the carbon fiber tape, forms the second take-up strap.The second take-up strap twines and forms the second coating layer 106.Graphite be equally a kind of effectively be high temperature and fire proofing, can effectively promote the resistance to elevated temperatures of cable.Be overcoat 108 outside the second coating layer 106 that the second take-up strap forms, overcoat 108 is polymer.Overcoat 108 mainly plays the effect of waterproof, insulation.
This high temperature-resistant cable 100 can be by following operation manufacturing:
At first prepare the metal cable core.Organic silicon ribbon of mica is mixed in afterwards preparation.Organic silicon ribbon is wrapped on the metal cable core.Prepare afterwards graphite granule, graphite granule is densified to 0.35～0.4g/cm
3, the screening diameter between 100～150 μ m, flat graphite granule, utilize the adhesive through carbonization that this graphite granule is bonded on the carbon fiber tape.The carbon fiber tape that is bonded with graphite granule is wrapped on organic silicon ribbon.Put at last overcoat polymer, obtain high temperature-resistant cable.
Adopt the solution of the present invention, increase two-layer high-temperature-resistant layer in the periphery of metal cable core, the carbon fiber tape by micaceous organic silicon ribbon and graphitiferous particle consists of respectively, utilizes the resistance to elevated temperatures of mica and graphite significantly to promote the heat-resisting ability of cable.
