The cable comprises a heat tracing tape, wherein the heat tracing tape comprises two parallel conductive core wires, metal resistance layers and a total PTC (positive temperature coefficient) material layer, each metal resistance layer is arranged outside each conductive core wire, a PTC material wrapping the peripheries of the metal resistance layers forms the total PTC material layer, an insulating layer made of an insulating material is arranged on the outer side of the total PTC material layer, a heat-insulating layer made of a heat-insulating material is arranged on the outer side of the insulating layer, an inner sheath is arranged on the outer side of the heat-insulating layer, a shielding layer is arranged on the outer side of the inner sheath, and an outer sheath made of a wear-resistant material is arranged on the outer side of the shielding layer. According to the control type self-temperature-controlling heat tracing cable, the structure is simple, the PTC material works stably, and the safety is high.
Description
Technical field
The present invention relates to accompanying-heat cable technical field, particularly relate to a kind of control type automatic temperature-controlled heat tracing cable.
Background technology
At present, accompanying-heat cable has been widely used in many fields, need to prevent the liquid substance in pipeline or tank from solidifying/slow the place of flowing velocity as mainly utilized in industrial aspect in oil, chemical industry, cogeneration power plant etc., in communal facility, be mainly used in companion's heat of fire protection pipeline, can be used in civilian heating of house and winter yard piping antifreeze in.In prior art, accompanying-heat cable also exists easily overheated, and ptc material is the defect such as breakdown easily.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of control type automatic temperature-controlled heat tracing cable, its structure is simple, and ptc material working stability, fail safe is high.
A kind of control type automatic temperature-controlled heat tracing cable that the present invention proposes; comprise heating tape; heating tape comprises two conductive core lines, metal restive layer and the total ptc layer that be arranged in parallel; the skin of every root conductive core line is metal restive layer; the ptc material being wrapped in metal restive layer periphery forms total ptc layer; it is insulating barrier that insulating material is made outside total ptc layer; it is heat-insulation layer that insulation material is made outside insulating barrier; it is internal protective cover outside heat-insulation layer; the outside of internal protective cover is screen, and the outside of screen is the outer protective jacket that high-abrasive material is made.
Preferably, heat-insulation layer has thin pore network structure.
Preferably, internal protective cover adopts elastomeric material to make.
Preferably, to be that the mesh grid of nickel plating copper wire is stacked form screen.
Preferably, in the matrix of outer protective jacket, Dispersed precipitate has wear-resisting enhancing particle.
Preferably, metal restive layer is evenly distributed in the circumference of conductive core line.
In the present invention, by the skin at conductive core line, metal restive layer is set, metal restive layer and total ptc layer form series relationship, therefore, along with under different temperatures, the resistance variations of ptc layer, metal restive layer can according to the distribution of the resistance adjustment voltage of ptc layer, thus the resistance of mode ptc layer too small time, because electric current is excessive and breakdown; Can effectively prevent cable around being folded in journey by arranging internal protective cover, the stress that inner discontinuity causes is concentrated; By arranging heat-insulation layer, can effectively prevent the functional layers such as the internal protective cover of cable overheated; By arranging screen, electromagnetic interference can be effectively reduced; By arranging outer protective jacket, effectively can reduce wearing and tearing, improving the useful life of cable.
Accompanying drawing explanation
