Abstract

The invention discloses a special high-temperature resistant compensating cable for a thermocouple. The compensating cable mainly comprises three aluminum alloy conductor wire cores, a tinned aluminum wire armor layer, a chlorosulfonated polyethylene sheath layer, a tinned nickel wire shielding layer, a nickel tape armor layer, a perfluoroethylene propylene copolymer insulating layer and a steel tape armor perfluoroethylene propylene copolymer sheath layer, wherein the tinned aluminum wire armor layer is wrapped outside the three aluminum alloy conductor wire cores; the chlorosulfonated polyethylene sheath layer is wrapped outside the tinned aluminum wire armor layer; a copper tape tensile wire is extruded in the tinned aluminum wire armor layer; and four nickel conductor wire cores and four copper conductor wire cores are extruded in the tinned nickel wire shielding layer. The compensating cable can operate for a long time within a temperature range of 100-250 DEG C, and is reliable in signal transmission, high in interference resistance, stable in electrical property, convenient to mount, and flexible; and a special requirement of a southern area for the cable at a high temperature in a summer can be met.

Description

The special-purpose compensating cable of a kind of high temperature resisting thermocouple

Technical field

The present invention relates to field of cables, relate in particular to the special-purpose compensating cable of a kind of high temperature resisting thermocouple.

Background technology

At present, the industrial and mining enterprises in south China province, summer, during daytime equipment operation work more than ambient temperature Ke Da Baidu, the residing circumstance of temperature difference of equipment in night rear cable out of service is large, in this special environment, need a kind of can be high temperature resistant, the type of resistance to marquis cable that again can be cold-resistant, to guarantee the normal operation of equipment under southern summer high temperature environment.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the special-purpose compensating cable of high temperature resisting thermocouple of the safety in production of a kind of satisfied southern summer high temperature weather factory.

The present invention takes following technical scheme to realize: the special-purpose compensating cable of a kind of high temperature resisting thermocouple, it mainly comprises aluminium alloy conductor core, zinc-plated aluminium wire armoured layer, chlorosulfonated polyethylene sheath layer, zinc-plated nickel wire screen, nickel strap armour, polyfluorinated ethylene insulating barrier and steel-tape armouring polyfluorinated ethylene restrictive coating, described aluminium alloy conductor core is three groups, outside three group aluminum alloy conductor thread cores, wrap up the zinc-plated aluminium wire armoured layer of one deck, outside described zinc-plated aluminium wire armoured layer, wrap up one deck chlorosulfonated polyethylene sheath layer, outside described chlorosulfonated polyethylene sheath layer, wrap up the zinc-plated nickel wire screen of one deck, outermost layer is set to steel-tape armouring polyfluorinated ethylene restrictive coating, described zinc-plated aluminium wire armoured layer inside is also extruded with a copper strips tensile cord, described zinc-plated nickel wire screen inside is extruded with four groups of nickel conductor thread cores and four groups of copper conductor cores, four groups of nickel conductor thread cores and four groups of copper conductor cores are disposed on zinc-plated nickel wire screen inside.

Described nickel conductor thread core is by two nickel conductors, a copper wire drainage thread and be wrapped in the zinc-plated aluminium wire braiding of one deck outside nickel conductor, copper wire drainage thread armour and form.

Described copper conductor core by a copper conductor, be wrapped in the nonmagnetic metal armour outside copper conductor and be extruded in aluminium wire drainage thread of nonmagnetic metal armour and form.

The present invention has following beneficial effect in sum: product of the present invention can long-term work in the temperature range of 100～250 ℃, signal transmission is reliable, antijamming capability is strong, electric performance stablity, softness, easy for installation, the specific (special) requirements to cable in the time of can meeting southern area summer high temperature.
