Abstract
The utility model discloses a high temperature resistant moisture resistant cable, including cable core, external insulation layer, shielding layer, water blocking layer and oversheath, the cable core includes that a plurality of leading bodies, every external all parcel of leading factor have fire -resistant mica layer, and the parcel has the inner insulating layer outside the fire -resistant mica layer, and the outer parcel of cable core has the external insulation layer, and the external insulation layer is equipped with the shielding layer outward, and the shielding layer is equipped with the water blocking layer outward, and the water blocking layer is equipped with the oversheath outward, is equipped with the filling layer between water blocking layer and the oversheath. This practical structure is reasonable, has improved the electric conductive property and the insulating properties of cable effectively to and to electromagnetic interference's shielding effect, compare with prior art, conveniently there has been great improvement at block -water performance and high temperature resistant, protected the waterproof nature and the fire resistance of cable, the life and the security that have improved the cable.
Description
Technical field
The utility model relates to technical field of electric wires and cables, is specifically related to a kind of high temperature resistant moisture resistant cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, power cable is widely used in oil, chemical industry, generating, the places such as space flight and aviation, such as in aviation, the cable used in the fields such as electric power, high all especially to the requirement of the high pressure resistant and diamagnetic jamming performance aspect of cable, but existing cable is because of its problem such as structure or material, can not satisfy the demand, but though existing power cable has insulation function during operation in above-mentioned environment, the quality requirement of cable is also constantly improved, because the operational environment in some fields is more severe, air is comparatively moist, this just requires that cable can at high temperature, operation in the environment of low temperature and soda acid and etchant gas, general cable can not play good moisture effect, moisture easily invades cable body inside, the situation of electric leakage or system short-circuit will be there is in this, if the incomplete words that cable possesses, work in these fields and benefit and safety can be affected.
Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, has excellent water resistance and the high temperature resistant moisture resistant cable of resistance to elevated temperatures.
The utility model is achieved through the following technical solutions:
A kind of high temperature resistant moisture resistant cable, comprise cable core, external insulation layer, screen, water blocking layer and oversheath, described cable core comprises some leading bodies, every bar leading body is all enclosed with fireproof mica layer outward, fireproof mica layer is wrapped with inner insulating layer, described cable core outer layer covers has external insulation layer, is provided with screen outside described external insulation layer, is provided with water blocking layer outside described screen, be provided with oversheath outside described water blocking layer, between described water blocking layer and oversheath, be provided with packed layer.
Further, inner insulating layer is Ceramic silicon rubber.
Further, described screen is that fiberglass fibers braiding forms.
Further, described water blocking layer is semiconductor waterstop.
Further, described packed layer is epoxy resin filling layer.
Further, described oversheath is that chlorosulfonated polyethylene extrusion molding is shaped.
The beneficial effects of the utility model are: this utility structure is reasonable; effectively improve electric conductivity and the insulation property of cable; and the shield effectiveness to electromagnetic interference; compared with prior art; there has been at block-water performance and high temperature resistant side and improve greatly; protect water proofing property and the anti-flammability of cable, improve useful life and the fail safe of cable.
