Abstract
The utility model discloses a heat-resisting compensation cable for a thermocouple. The heat-resisting compensation cable comprises two conductor groups, wherein the two conductor groups comprise two alloy conductors of which the outer sides are wrapped with insulation layers respectively; the insulation layers are formed by bonding glass fiber cloth between a mica tape on the inner side and a high-polymer thin film on the outer side; an olive-shaped elastic body is arranged between the alloy conductor wrapped with the insulation layers; inner wrapping layers which are formed by wrapping glass fiber tapes are wrapped on the outer sides of the two conductor groups; the two conductor groups are stranded with each other to form a bundle; an outer wrapping layer which is formed by wrapping the glass fiber tape is wrapped on the outer side of the bundled conductor groups; and a fireproof layer and a shreath layer are wrapped on the outer side of the outer wrapping layer sequentially. The heat-resisting compensation cable has novel structure and design; the elastic body is arranged between the insulation layers of the conductors, so the anti-squeezing property of the cable is improved; meanwhile, due to the design of the insulation layers and the fireproof layer of the cable, the fireproof characteristic is improved, and the fireproof point is 800 DEG C; therefore, a thermotechnical instrument system can work normally under the condition of high temperature and emergencies, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the compensating cable field, relates in particular to a kind of thermocouple and uses heat-resisting compensating cable.
Background technology:
Compensating cable mainly is applicable to the connection of the Thermal Meter system of (60 ℃-800 ℃) under the hot conditions, can be widely used in fields such as metallurgy, casting, oil refining, chemical industry, machinery.
Electric heating cable in the market is with compensating wire (cable); Main adopt polyvinyl chloride, crosslinked polyethylene, silicon rubber, fluoroplastics, gather insulation and sheath material such as tetrafluoro tetraene; Its maximum operating temperature is only gathered the tetrafluoro tetraene can reach 260 ℃, can't in higher temperature environment, use.
There is defective in thermocouple cable for present, mainly is that the anti-extrusion performance of cable is relatively poor, and fire-resistance property does not reach the requirement of actual working environment.
The utility model content:
For solving the problem that prior art exists, the utility model provides a kind of thermocouple to use heat-resisting compensating cable, and anti-extrusion performance improves; Fire-resistance property promotes, can anti-800 ℃ high temperature, and product is employed new technology, new technology; Make its heat resisting temperature-60 ℃ of-800 ℃ of scopes, its line (cable) does not harden yet at low temperatures, can any bending; Technical performance is reliable, especially when flame directly is burned to the line surface, can not be short-circuited within a certain period of time and open circuit fault; The distinctive thermal endurance of this product is a silicon rubber with to gather product such as tetrafluoro incomparable, thereby ensures Thermal Meter system operate as normal under high temperature and emergency circumstances.
The technical scheme of the utility model is following:
Thermocouple is used heat-resisting compensating cable; Comprise two conductor groups; It is characterized in that: two conductor groups comprise that two outsides are enclosed with the alloy conductor of insulating barrier respectively, and insulating barrier adopts the wrapped formation of bonding glass fiber cloth between the polymer film of the inboard mica tape outside, is provided with olivary elastomer between the alloy conductor of wrap insulate layer and separates; Two conductor group outsides are enclosed with the interior lapping layer of the wrapped formation of glass fibre belt respectively; Two mutual stranded bunchys of conductor group, the outside is enclosed with the outer lapping layer of the wrapped formation of glass fibre belt behind the bunchy, and the outer lapping layer outside is enclosed with flame retardant coating, restrictive coating successively.
Described thermocouple is used heat-resisting compensating cable, it is characterized in that: described alloy conductor material adopts aluminium alloy.
Described thermocouple is used heat-resisting compensating cable, it is characterized in that: described flame retardant coating adopts the several layers of overlapping wrapped formation of synthetic mica tape.
Described thermocouple is used heat-resisting compensating cable, it is characterized in that: described restrictive coating adopts glass fiber tape to be woven into netted formation.
The utility model has the advantages that:
The utility model structural design is novel, sets up elastomer between the insulating barrier of conductor, has improved the anti-extrusion performance of cable; The insulating barrier of cable, the design of flame retardant coating simultaneously improved fire-resistance property; Having overcome traditional compensation lead of thermocouple (cable) can only use in 260 ℃ and following lower environment, and the product heatproof reaches 800 ℃, has improved quite a few times than the heat resistance of conventional general high temperature-resistant cable; Insulation of being adopted and sheath material all can normally move in 800 ℃ environment; Product has resistance to elevated temperatures preferably, can ensure Thermal Meter system operate as normal under high temperature and emergency circumstances, the useful life of having improved this series products.
