Description
Technical field
The utility model relates to a kind of compensating cable for thermocouple, relates in particular to a kind of temperature-resistance environmental-protection compensating cable for thermocouple, belongs to technical field of electric wires and cables.
Background technology
Compensating cable for thermocouple, it is the identical a pair of lead that has insulating barrier of nominal value that in certain temperature range, (comprises normal temperature) and have with the thermo-electromotive force of the thermocouple that is mated, connect thermocouple and measurement mechanism (galvanometer etc.) with them, to compensate the error that variations in temperature was produced of they and thermocouple junction.Compensating wire is divided into two kinds of extended pattern and offset-types.
The character of compensating cable has determined it to have very wide application or has adapted to the complex environment factor.Its primary structure is alloy conductor, insulating barrier and restrictive coating.Because application and environment requirement need it to have the temperature resistant grade of the feature of environmental protection, certain limit.In long-term serviceability temperature is that compensating cable market demand about 150 ℃ is more and more, and adopts traditional electrical material, is difficult to satisfy the demand in market.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of temperature-resistance environmental-protection compensating cable for thermocouple is provided, and makes it have fire-retardant, anti-height, Halogen, oil resistant, performance such as wear-resisting.
The utility model technical solution problem adopts following technical scheme:
The design feature of a kind of temperature-resistance environmental-protection compensating cable for thermocouple of the utility model is:
The utility model temperature-resistance environmental-protection compensating cable for thermocouple, its design feature is that positive grid alloy silk conductor and negative pole alloy silk conductor adopt single or many alloy silk conductor lay configuration, the anodal insulating barrier and the negative pole insulating barrier that extrude polyester-ether thermoplastic elastomer (TPE) TPE-E on positive grid alloy silk conductor and negative pole alloy silk conductor respectively constitute insulated wire cores, each is twisted into the pair twist group to anodal insulated wire cores and negative pole insulated wire cores, the unit sheath that extrudes polyester-ether thermoplastic elastomer (TPE) TPE-E on the pair twist group constitutes unit pair twist group, unit pair twist group is pressed in the same way or reverse concentric stranding stranding constitutes cable core, form belting layer at the wrapped high temperature resistant nonwoven fabric belts of the outer surface of cable core, form total screen in the appearance of belting layer and total shielding drainage thread with the tinned copper wire of braiding, extrude polyester-ether thermoplastic elastomer (TPE) TPE-E material at the skin of total screen and form external sheath layer.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the polyester that is adopted in the utility model-ether thermoplastic elastomer TPE-E is good comprehensive properties insulation and sheath material, long service life, and molecule falls that Jie's gradient is slow, and under normal circumstances, decades are stable, and security reliability is strong;
2, the dielectric strength of TPE-E material substantially exceeds materials such as low smoke, zero halogen cross-linked polyolefin, PVC, very suitable manufacturing thin insulating type compensating cable;
3, the temperature resistant grade height of TPE-E material, the highest instantaneous heat resisting temperature reaches 200 ℃, and heat resisting temperature reaches 175 ℃ in short-term.Long-term serviceability temperature is 150 ℃, can satisfy the ambient temperature requirement of broad;
4, the fire resistance of TPE-E material is good, belongs to Halogen, phosphorus-free flame-retarding material;
5, the TPE-E material is because hardness is higher, and as insulation and sheath, resistance to wear is all very good, and when the equipment vibration, electric wire that lays or cable insulation can not wear and tear and puncture, and sheath can be not worn out yet;
6, TPE-E material oil resistance is good, contact with oil product such as machine oil, and not serious expansion or contraction, after the immersion oil test, can be by at voltage test, so energy operate as normal under the mist of oil environment is being arranged;
7, TPE-E material ultraviolet-resistant aging performance is also better, does not ftracture, and keeps color and luster.
