Abstract
The invention provides a special type compensating lead wire for a high-flame-resistant temperature-resisting corrosion-resisting thermocouple and relates to the technical field of compensating cables. The special type compensating lead wire comprises a cable core, wherein a main flame-resistant wrapping tape layer, a tinned copper wire braiding main shielding layer, an inner liner layer, an armor layer and an outer protective layer are sequentially arranged on the outer side of the cable core. A filling layer is arranged between the main flame-resistant wrapping tape layer and the cable core. The cable core comprises three groups of stranded wire cores, each group of wire cores includes two stranded insulating conductors, and inner wrapping tape layers, tinned copper wire split-phase shielding layers and outer wrapping tape layers are sequentially arranged on the outer sides of the stranded insulating conductors. Each insulating conductor respectively comprises an alloy wire conductor. The alloy wire conductor is wrapped by a Teflon insulating layer. The special type compensating lead wire for the high-flame-resistant temperature-resisting corrosion-resisting thermocouple has excellent flame-resistant, high-temperature-resisting, ageing resistant and anti-interference performance and can be used in a special environment for a long period of time.
Description
Technical field
The present invention relates to compensating cable technical field, relate 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 and in certain temperature range, (comprises normal temperature) and have a pair of wire with insulating barrier identical with the nominal value of the thermo-electromotive force of mated thermocouple with compensating wire, with they connect thermocouple and measurement mechanism, to compensate the error that variations in temperature was produced of they and thermocouple junction.The high temperature resistant corrosion resistant fire resistance of compensating wire of prior art is poor, and particularly sensing temperature error under high-temperature corrosion environment is large, and compensating wire insulation is easily aging.Therefore, the compensating wire of prior art must further improve.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of high temperature resistant, fire-retardant, corrosion resistant, ageing-resistant performance, 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 high-temperature corrosion environment.
The present invention includes cable core, set gradually fire-retardant overall budget belt, tinned copper wire braided overall-shielding layer, inner covering, armour and outer jacket in 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 stranded insulated electric conductors mutually, sets gradually interior belting layer, tinned copper wire phase-splitting screen and outer belting layer in described two stranded insulated electric conductor outsides; Described every insulated electric conductor comprises respectively B alloy wire conductor; Extrude teflon insulation layer outward at described B alloy wire conductor.
Insulation of the present invention and sheath material all adopt fluoroplastics, adopt entirety expressing technique continuously, there is good electrical property and acid and alkali-resistance profit performance, phase-splitting shielding and total shielding adopt tinned copper wire, make this compensating wire there is good fire-retardant, high temperature resistant, ageing-resistant, interference free performance, can meet under particular surroundings and use for a long time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes cable core, set 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 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 stranded insulated electric conductors 8 mutually, sets gradually interior belting layer 9, tinned copper wire phase-splitting screen 10 and outer belting layer 11 in two stranded insulated electric conductor 8 outsides; Every insulated electric conductor 8 comprises respectively B alloy wire conductor 12, extrudes teflon insulation 13 outside B alloy wire conductor 12.
