Description
Technical field
The utility model relates to field of cables, specifically is a kind of high temperature resistant, low electric capacity tension shielded flexible data cable.
Background technology
At smelting iron and steel, the new transmission system of geological exploration field will be used high temperature resistant usually and be convenient to the mobile cable that uses.Common data cable adopts solid conductor, and cable is use fixedly, and excessively frequent the use causes the conductor distortion, breaks thereby cause insulation.At steel plant's equipment and geological exploration field, the cable use touches high temperature, and the common cable non-refractory can not satisfy engineering and use.
The utility model content
The purpose of this utility model provides a kind of flexible high temperature resistant, low electric capacity tension shielded flexible data cable.
The technical solution of the utility model is as follows:
A kind of high temperature resistant, low electric capacity tension shielded flexible data cable, comprise many mutually stranded conductors, it is characterized in that: described many conductors two two-phases are stranded, every conductor includes many tinned copper wires respectively, described many tinned copper wires are extruded with the perfluoroethylene-propylene insulating barrier outward, center between the described many conductors is provided with strengthening core, and described strengthening core includes aramid fiber, and described aramid fiber has coating layer outward; Described many conductors are coated with internal shield, outer shielding layer and silicone rubber jacket outward successively, and described internal shield is formed by the vertical bag of plastic-aluminum band, and described outer shielding layer is formed by the tinned copper wire braiding.
Described a kind of high temperature resistant, low electric capacity tension shielded flexible data cable, it is characterized in that: the dielectric constant of described perfluoroethylene-propylene insulating barrier≤2.2, the thickness of perfluoroethylene-propylene insulating barrier are 0.25mm.
The beneficial effects of the utility model:
1, conductor of the present utility model adopts tinned copper wire, stranded rounding, structure closely, be difficult for loose;
2, the thickness of perfluoroethylene-propylene insulating barrier of the present utility model is 0.25mm, anti-high temperature below 200 ℃, make cable more soft, easier bending, can be crooked flexibly under the complex environment of address exploration, restrictive coating uses soft silastic material, and heatproof makes that below 180 ℃ whole cable can be explored in the address, the safe operation below 200 ℃ of field of iron and steel smelting ambient temperature;
3, the dielectric constant of perfluoroethylene-propylene insulating barrier of the present utility model≤2.2, lower than the dielectric constant of conventional polyethylene insulating barrier 2.3, dielectric constant is directly proportional with electric capacity, makes that the electric capacity of cable is lower under the same dielectric thickness;
4, the utility model adopts plastic-aluminum band and tinned copper wire vertical bag, the inside and outside shielding of braiding formation respectively, makes shield effectiveness better;
5, the utility model adopts the aramid fiber of high elastic modulus and intensity to add coating layer composition strengthening core, makes whole cable have good tension effect, can adapt to geological prospecting, the requirement in fields such as petroleum detection preferably.
