Description
Technical field
The present invention relates to cable design manufacturing technology fields, more particularly to a kind of high temperature-resistant cable.
Background technique
It is continuously improved along with China's economic and technique level, wires and cables industry technology has also obtained high speed development.With
The continuous expansion of the industry sizes such as China's power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, it is right
The demand of wire and cable will also increase rapidly.Cable is usually by several or several groups of conducting wires form, mutually exhausted by one or more
The conductor and external insulating protective layer of edge are made, and electric power or information are transferred to the conducting wire at another place from one.Or by several
Or the cable of similar rope made of several groups of wire strandings, mutually insulated between every group of conducting wire, and often turned round around a center
At entire outside is surrounded by the coating of high-insulation.Cable has interior energization, the feature of external insulation.Cable has power cable, control
It is cable processed, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, peculiar to vessel
Cable, mine cable, aluminium alloy cable etc..Wherein, high temperature-resistant cable, which refers to, to work normally under high temperature environment for a long time, tool
Have that high temperature resistant, waterproof, resistance to various corrosive gas, ageing-resistant, the excellent properties such as do not burn, is suitble to metallurgy, electric power, petrochemical industry etc. capable
Industry.Currently, high temperature-resistant cable mainly includes oversheath, thermal insulation layer and cable core, oversheath is generally haloflex, thermal insulation layer
For ceramic polyolefin, although this high temperature-resistant cable can also bear conventional hot environment.But in use often
There is high temperature and be transferred to cable core, so that cable core works under high temperature environment for a long time, causes its service performance by very big shadow
It rings, its deformed damaged is also resulted in when serious, so that it cannot use, reduce the service life of cable, affect the matter of cable
Amount.
Summary of the invention
Present invention is primarily intended to solve the above deficiency, provides one kind and effectively improve cable high temperature resistance, it is ensured that is resistance to
The high temperature-resistant cable of high-temperature cable quality.
A kind of high temperature-resistant cable, including oversheath, thermal insulation layer, vacuum layer, insulating layer, separation gas layer, cable core, segmentation
Mark, vacuum layer sealing ring and separation gas layer sealing ring, thermal insulation layer are arranged on the inside of oversheath, and vacuum layer is arranged in thermal insulation layer
Inside, insulating layer are arranged on the inside of vacuum layer, and separation gas layer is arranged on the inside of insulating layer, and cable core is arranged in separation gas layer
It is interior, segment identification setting outside the oversheath on, vacuum layer sealing ring is arranged in vacuum layer and against segment identification, and gas is isolated
Body layer sealing ring is arranged in separation gas layer and opposite segment identification, is provided with vacuum layer segmentation between vacuum layer sealing ring
Area is provided with separation gas layer segment identifier between separation gas layer sealing ring.
Further, the separation gas of the separation gas layer of the high temperature-resistant cable is nitrogen or inert gas.
Further, the length of the vacuum layer segment identifier of the high temperature-resistant cable and separation gas layer segment identifier be to centimetre.
Further, the jacket material of the high temperature-resistant cable is haloflex, and insulating layer material is ceramic polyolefin,
Insulating layer material is polyethylene.
Compared with the existing technology, the advantageous effects that the present invention obtains are as follows: the high temperature-resistant cable can be avoided preferably
Often occur high temperature in use and be transferred to the problem of cable core leads to its deformed damaged, has ensured that cable is adapted in height
Long-term work under warm environment, it is ensured that its service performance ensure that its service life, improve the quality of cable.

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and example is served only for explaining invention, not
For limiting the scope of the invention.
A kind of high temperature-resistant cable, including oversheath 1, thermal insulation layer 2, vacuum layer 3, insulating layer 4, separation gas layer 5, cable core
6, segment identification 7, vacuum layer sealing ring 8 and separation gas layer sealing ring 9, the setting of thermal insulation layer 2 is in 1 inside of oversheath, vacuum layer 3
Setting is in 2 inside of thermal insulation layer, and the setting of insulating layer 4 is in 3 inside of vacuum layer, and the setting of separation gas layer 5 is in 4 inside of insulating layer, cable
Core 6 is arranged in separation gas layer 5, the setting of segment identification 7 outside the oversheath 1 on, vacuum layer sealing ring 8 is arranged in vacuum layer
In 3 and against segment identification 7, separation gas layer sealing ring 9 is arranged in separation gas layer 5 and opposite segment identification 7, vacuum layer
It is provided with vacuum layer segment identifier 10 between sealing ring 8, separation gas layer segment identifier is provided between separation gas layer sealing ring 9
11。
To keep its heat insulation more preferable.The separation gas of the separation gas layer 5 of the high temperature-resistant cable is nitrogen or indifferent gas
Body.
To make to save material, cost is reduced.The vacuum layer segment identifier 10 and separation gas layer segment identifier of the high temperature-resistant cable
11 length is 6 to 10 centimetres.
To make it, the service life is longer, it is ensured that its quality.1 material of oversheath of the high temperature-resistant cable is haloflex,
