Abstract
The utility model discloses a compensating cable for a high-temperature resistant thermocouple. The compensating cable comprises a plurality of conductors, wherein every two conductors covered with insulating layers are stranded to form a wire core; isolation layers I cover the outer side of each of the wire cores; the plurality of groups of wire cores are stranded, and isolation layers II cover the stranded wire cores; flame-retardant materials are filled in the isolation layers I; silicon rubber is extruded and filled between the isolation layers I and the isolation layers II; shielding layers cover the outer sides of the isolation layers II; and sheaths cover the outer sides of the shielding layers. By the compensating cable, the design of a double-layer isolation is adopted, the silicon rubbers with excellent high-temperature resistant effect can be filled between the isolation layers; and a glass fiber rope made of the flame-retardant materials is also filled in the inner layer of the compensating cable, so that the influence on the cable conductors can be effectively avoided, and the requirement of the compensating cable connected with the high-temperature resistant thermocouple can be met; and therefore, the cable can be normally operated under the high temperature, and signals can be transmitted accurately. The compensating cable has a simple structure and is low in production cost.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of high temperature resistant compensating cable for thermocouple.
Background technology
Be used to connect the compensating cable of thermocouple; Its effect is the cold junction that is used for extending the multiple spot thermode and moves thermocouple, connects and composes the multi-point temperature measurement system with Displaying Meter, when using high temperature thermocouple; The mechanical and physical performance of the insulation of the common compensating cable under the high temperature and sheath etc., the influence that electrical property all will receive high temperature, oxidation, impulsive force; Thereby the physical and mechanical properties of cable is descended and cisco unity malfunction, and therefore the signal of telecommunication of transmission has just had deviation, can not normally use.
The utility model content
The purpose of the utility model provides a kind of high temperature resistant compensating cable for thermocouple, with the not good and problem of cisco unity malfunction of the resistance to elevated temperatures that solves compensating cable in the prior art.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high temperature resistant compensating cable for thermocouple is characterized in that: include several conductors, per two stranded backs of conductor that are coated with insulating barrier form core; Every core is coated with separator one; Be coated with separator two after the array core is stranded, be filled with fire proofing in the said separator one, extrude between said separator one and the separator two and be filled with silicon rubber; Said separator two is wrapped with screen, and screen is wrapped with sheath.
Described a kind of high temperature resistant compensating cable for thermocouple is characterized in that: said fire proofing is a glass cord.
The beneficial effect of the utility model is:
The utility model adopts double-deck isolation design, and fills the good silicon rubber of high-temperature resistant result between the separator, and internal layer also is filled with the fire proofing glass cord; Avoid the influence of high temperature effectively to cable conductor; Satisfy the demand of the compensating cable that can be connected, make cable operate as normal at high temperature, transmit accurate signal with high temperature thermocouple; And the utility model is simple in structure, and production cost is not high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
