Abstract
The utility model discloses a kind of temperature sensing cable, include conductor, described conductor is made up of elastic wire, be surrounded by the semiconductor material NTC insulation course of negative temperature coefficient in the outside of described conductor, two conductors are placed side by side and be coated with in outside that tinned copper wire adds aramid yarn woven shield, plumbous plastic composite strip indulges covering successively, calcining Mica tape layer and Polyvinylchloride oversheath.Originally the semiconductor material NTC insulation course of negative temperature coefficient is employed, under normal monitoring state, two conductors are all in state of insulation, when ambient temperature rises to predetermined action temperature time, temperature-sensitive material will break, and two steel wires can produce short circuit, and load module produces warning after being checked through short-circuit signal immediately, safe and reliable, jacket material makes cable have the performances such as softness, fire-retardant, uvioresistant.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of temperature sensing cable.
Background technology
Temperature sensing cable can be used for the places such as power house, transformer station, conduit line, tunnel, interlayer, travelling belt, and temperature sensing cable detector is reliable and stable, is applicable to the fire detecting/monitoring of rugged surroundings.Temperature sensing cable has the ability of the long continuous monitoring and protecting object temperature along all fronts.Existing temperature sensing cable can't meet the demand of use, needs to improve.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of temperature sensing cable.
The utility model is achieved through the following technical solutions:
A kind of temperature sensing cable, include conductor, described conductor is made up of elastic wire, be surrounded by the semiconductor material NTC insulation course of negative temperature coefficient in the outside of described conductor, two conductors are placed side by side and be coated with in outside that tinned copper wire adds aramid yarn woven shield, plumbous plastic composite strip indulges covering successively, calcining Mica tape layer and Polyvinylchloride oversheath.
The utility model has the advantages that: the semiconductor material NTC insulation course originally employing negative temperature coefficient, under normal monitoring state, two conductors are all in state of insulation, when ambient temperature rises to predetermined action temperature time, temperature-sensitive material will break, and two steel wires can produce short circuit, and load module produces warning after being checked through short-circuit signal immediately, safe and reliable, jacket material makes cable have the performances such as softness, fire-retardant, uvioresistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
