Abstract

A special compensating wire for a highly flame-retardant temperature-resistant anticorrosion thermocouple relates to the technical field of the compensating cable. The special compensating wire for the highly flame-retardant temperature-resistant anticorrosion thermocouple comprises a cable core, wherein a flame-retardant total wrapping tape layer, a tinned copper wire braided total shielding layer, a lining layer, an armoring layer and an outer protection layer are orderly arranged outside the cable core; a filler layer is arranged between the flame-retardant total wrapping tape layer and the cable core; the cable core comprises three groups of wire cores stranded with one another; each group of wire cores includes two insulating conductors stranded with each other; an inner wrapping tape layer, a tinned copper wire individual shielding layer and an outer wrapping tape layer are orderly arranged outside the two stranded insulating conductors; each insulating conductor comprises an alloy wire conductor; and a polytetrafluoroethylene insulating layer is extruded to cover the alloy wire conductor. The special compensating wire for the highly flame-retardant temperature-resistant anticorrosion thermocouple has excellent flame resistant, high temperature resistant, aging resistant and interference resistant properties and thus can be applied in special environments for a long time.

Description

The extraordinary compensating wire of high flame retardant heat-proof corrosion resistant thermocouple
Technical field
The utility model relates to the compensating cable technical field, relates in particular to the extraordinary compensating wire of the high temperature resistant corrosion resistance thermo couple of a kind of high flame retardant.
Background technology
Thermocouple refers to (to comprise normal temperature) in certain temperature range and has a pair of wire with insulating barrier identical with the nominal value of the thermo-electromotive force of the thermocouple that mates with compensating wire, connect thermocouple and measurement mechanism with them, to compensate the error that variations in temperature was produced of they and thermocouple junction.The compensating wire of prior art is high temperature resistant, and the corrosion resistant fire resistance is relatively poor, and particularly sensing temperature error under high-temperature corrosion environment is large, and the compensating wire insulation is aging easily.Therefore, the compensating wire of prior art must further improve.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of high temperature resistant, fire-retardant, corrosion resistant, ageing-resistant performance are provided, the extraordinary compensating wire of the high temperature resistant corrosion resistance thermo couple of high flame retardant that can use in long-term safety under the high-temperature corrosion environment.
The utility model comprises cable core, sets gradually fire-retardant overall budget belt, tinned copper wire braided overall-shielding layer, inner covering, armour and outer jacket in the described cable core outside; Between described fire-retardant overall budget belt and cable core, packed layer is set; Described cable core comprises three groups of mutual stranded cores, and described every group of core includes two mutually stranded eradication edge conductors, sets gradually interior belting layer, tinned copper wire phase-splitting screen and outer belting layer in the described two stranded eradication edge conductors outsides; Described every eradication edge conductor comprises respectively the B alloy wire conductor; Outside described B alloy wire conductor, extrude the teflon insulation layer.
The utility model insulation and sheath material all adopt fluoroplastics, adopt whole continuously expressing technique, have good electrical property and acid and alkali-resistance profit performance, tinned copper wire is adopted in phase-splitting shielding and total shielding, make this compensating wire have good fire-retardant, high temperature resistant, ageing-resistant, interference free performance, can satisfy under particular surroundings and use for a long time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, sets gradually fire-retardant overall budget belt 1, tinned copper wire braided overall-shielding layer 2, inner covering 3, armour 4 and outer jacket 5 in the cable core outside; Between fire-retardant overall budget belt 1 and cable core, packed layer 6 is set; Cable core comprises three groups of mutual stranded cores 7, and every group of core 7 includes two mutually stranded eradication edge conductors 8, sets gradually interior belting layer 9, tinned copper wire phase-splitting screen 10 and outer belting layer 11 in stranded two eradication edge conductors, 8 outsides; Every eradication edge conductor 8 comprises respectively B alloy wire conductor 12, extrudes teflon insulation 13 outside B alloy wire conductor 12.
