Abstract
The utility model discloses a tensile and water-proof compensating cable which comprises a plurality of insulated cable cores. The plurality of the insulated cable cores are taped with a taped covering layer after being twisted with strengthening steel wires, a water-blocking tape is filled in the taped covering layer, and an internal polyolefin sheath, a seamless metal sheath, a wire armoring layer and an external sheath are covered outside the taped covering layer successively. According to the tensile and water-proof compensating cable, the water-blocking tape is taped outside the cable cores, and the seamless metal sheath is arranged, so that the water-proof property of the cable is enhanced effectively; the design of the twisted strengthening steel wires and the wire armoring is used, so that the cable mechanical strength is enhanced, and the cable tensile performance is guaranteed; and the tensile and water-proof compensating cable has good oil resistance and high-temperature resistance.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of tension waterproof compensating cable.
Background technology
Be used for connecting the compensating cable of thermocouple, its effect is the cold junction that extends multiple spot thermode and mobile thermocouple, connect and compose multi-point temperature measurement system with Displaying Meter, existing cable is in order to improve water resistance, generally be that surface cover has sheath outside cable, between cable and sheath, sealing ring is housed, to play the effect of waterproof, yet in actual use, its waterproof effect is not good, tensile property is also relatively poor, when under the environment of water is arranged, using for a long time, occur easily infiltration in the cable or the problem such as cable breakdown, and then cause the accidents such as short circuit, cause casualties and property loss when serious, so there is potential safety hazard in water proofing property and the relatively poor compensating cable of pull resistance, affects the normal use of cable.
The utility model content
The purpose of this utility model provides a kind of tension waterproof compensating cable, because water resistance is not good and tensile property is relatively poor, seeping water in easy inside, and then causes the generation of short circuit accident, has the problem of potential safety hazard with cable in the solution prior art.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tension waterproof compensating cable, it is characterized in that: comprise several insulated wire cores, be surrounded with lapping layer after several insulated wire cores are stranded with the reinforcement steel wire, be filled with waterstop in the described lapping layer, described lapping layer is coated with polyolefin inner sheath, seamless metal cover, wire armoring layer and oversheath outward successively.
Described a kind of tension waterproof compensating cable is characterized in that: adopt the perfluoroethylene-propylene material to make insulating barrier in the described insulated wire cores.
Described a kind of tension waterproof compensating cable is characterized in that: described oversheath adopts polyvinyl chloride to make.
The beneficial effects of the utility model are:
The utility model is surrounded with waterstop outside cable core, and be provided with the seamless metal cover, effectively promoted the water proofing property of cable, and adopt stranded reinforcement steel wire and steel wire armoured design, to strengthen the mechanical strength of cable, guaranteed the tensile property of cable, and the utility model also have preferably oil resistant, resistance to elevated temperatures.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of tension waterproof compensating cable, comprise several insulated wire cores 1, several insulated wire cores 1 with strengthen steel wire 2 and be surrounded with lapping layer 4 after stranded, be filled with waterstop 3 in the lapping layer 4, lapping layer 4 outer polyolefin inner sheath 5, seamless metal cover 6, wire armoring layer 7 and the oversheaths 8 of being coated with successively.
Adopt the perfluoroethylene-propylene material to make insulating barrier in the insulated wire cores 1.Oversheath 8 adopts polyvinyl chloride to make.
Claims (3)
1. tension waterproof compensating cable, it is characterized in that: comprise several insulated wire cores, be surrounded with lapping layer after several insulated wire cores are stranded with the reinforcement steel wire, be filled with waterstop in the described lapping layer, described lapping layer is coated with polyolefin inner sheath, seamless metal cover, wire armoring layer and oversheath outward successively.
