Abstract

The utility model discloses a compensation cable used for thermoelectric couple, including the cable core, the cable core has set gradually outward around covering, total shielding layer, inner liner, armor and outer jacket, cable core and fill around the covering between and have the filling layer, the cable core is the sinle silk transposition of 4 groups and forms, and every group sinle silk sets up the phase separating shielding layer all including two insulated conductor of transposition each other outside two insulated conductor of transposition each other. This compensation cable used for thermoelectric couple have good fire -retardant, do not have steamed low cigarette, temperature resistant, corrosion resistant, tensile strength, can adapt to long -term operation requirement under the special environment.

Description

A kind of compensating cable for thermocouple
Technical field
This utility model relates to field of cables, particularly to a kind of compensating cable.
Background technology
Compensating cable for thermocouple (wire) refers to (include room temperature) in certain temperature range to be had and institute A pair wire with insulating barrier that the nominal value of the thermo-electromotive force of the thermocouple joined is identical, connects heat with them Galvanic couple and measurement apparatus, to compensate error produced by they variations in temperature with thermocouple junction.
The thermocouple compensation cable of prior art is not reasonable due to structure, causes its mechanical and physical performance and letter Number transmission performance can not meet needs, therefore, it is necessary to improve electricity and the mechanics of existing compensating cable further Performance.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of compensating cable for thermocouple, It has excellent fire-retardant, low smoke, zero halogen, heatproof, corrosion resistant, tensile property, it is possible to adapt under special environment Life-time service requirement.For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of compensating cable for thermocouple, including cable core, be disposed with outside cable core lapping layer, total screen layer, Inner liner, armor and outer jacket;Packed layer it is filled with between cable core and lapping layer;Described cable core is 4 groups Core is stranded to be formed, and often group core all includes the most stranded two piece insulated electric conductor, at the most stranded two Split-phase screen layer is set outside insulated electric conductor.
Preferably, described insulated electric conductor is tin-coated copper tow strand conductor or B alloy wire conductor;Outside described conductor It is provided with insulating barrier.
Preferably, described insulating barrier uses and extrudes crosslinked polyolefin materials.
Preferably, described split-phase screen layer uses aluminium-plastic tape.
Preferably, described packed layer uses bittern-free flame-proof material.
Preferably, described total screen layer is tincopper fuse wire braided armor.
Preferably, described outer jacket uses halogen-free and low-smoke flame-retardant polyolefin material.
Preferably, described armor is steel wire armor layer.
The beneficial effects of the utility model are that this compensating cable product selects LSOH anti-flaming material, have Excellent LSOH anti-flaming, heatproof, corrosion resistant and environmental-protecting performance;It is provided with aluminium-plastic tape split-phase screen layer Screen layer total with tinned copper wire improves product interference free performance, and temperature measurement error is little, and precision is high;Armor Add, make the effect of the resisting longitudinal active force of cable be greatly enhanced, extend cable service life, reduce Power supply cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, insulated electric conductor;2, insulating barrier;3, split-phase screen layer;4, packed layer;5, wrapped Layer;6, total screen layer;7, inner liner;8, armor;9, outer jacket.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this Utility model is described in further detail.
With reference to the structural representation shown in Fig. 1, a kind of compensating cable for thermocouple, including 4 groups of mutually stranded lines Core, after described 4 groups of stranded core strandings, sets gradually halogen-free flameproof band lapping layer 5, tin plating outside cable core The total screen layer of proof copper-wire braided 6, halogen-free and low-smoke flame-retardant polyolefin inner liner 7, steel wire armor layer 8 and low smoke, zero halogen resistance Combustion polyolefin outer jacket 9;Between described lapping layer 5 and core, halogen-free flameproof packed layer 4 is set;Described often group Core all includes two the most stranded eradication edge layer conductors, sets successively outside described stranded two insulated electric conductors 1 Put aluminium-plastic tape split-phase screen layer 3;Described every insulated electric conductor 1 is tin-coated copper tow strand conductor or B alloy wire Conductor;It is externally provided with at described insulated electric conductor 1 and extrudes cross-linked polyolefin insulating barrier 2.
Compensating cable of the present utility model has LSOH anti-flaming, heatproof, corrosion resistant and the environmental-protecting performance of excellence; Aluminium-plastic tape split-phase screen layer 3 and the total screen layer of tinned copper wire 6 improve product interference free performance, and thermometric is by mistake Difference is little, and precision is high;The addition of steel wire armor layer 8, makes the effect of the resisting longitudinal active force of cable be greatly enhanced.
Certain above-mentioned embodiment only for technology of the present utility model design and feature are described, its object is to allow Person skilled in the art will appreciate that content of the present utility model and implements according to this, can not limit this with this The protection domain of utility model.All modifications done according to the spirit of this utility model main technical schemes, All should contain within protection domain of the present utility model.
