Description
Technical field
The utility model relates to accompanying-heat cable technical field, relates in particular 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, as mainly utilized in oil, chemical industry, cogeneration power plant etc. and need to prevent the slow place of solidify/flowing velocity of liquid substance in pipeline or tank in industrial aspect, the companion's heat that is mainly used in fire protection pipeline aspect communal facility can be used for heating of house and the antifreeze aspect of yard piping in winter aspect civilian.The defects such as in prior art, accompanying-heat cable also exists easily overheated, and ptc material is easy breakdown.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of control type automatic temperature-controlled heat tracing cable, it is simple in structure, and ptc material working stability is safe.
A kind of control type automatic temperature-controlled heat tracing cable the utility model proposes; comprise heating tape; heating tape comprises two conductive core lines, metal electric resistance layer and the total ptc layer be arrangeding in parallel; the skin of every conductive core line is metal electric resistance layer; the ptc material that is wrapped in metal electric resistance layer periphery forms total ptc layer; the insulating barrier that make for insulating material in total ptc layer outside; the heat-insulation layer that make for insulation material in insulating barrier outside; heat-insulation layer outside is internal protective cover; 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, screen is stacked the forming of nickel plating copper wire mesh grid.
Preferably, in the matrix of outer protective jacket, disperse is distributed with wear-resisting enhancing particle.
Preferably, metal electric resistance layer is evenly distributed on making progress in week of conductive core line.
In the utility model, by the skin at conductive core line, metal electric resistance layer is set, metal electric resistance layer forms series relationship with total ptc layer, therefore, under different temperatures, the resistance variations of ptc layer, metal electric resistance layer can be according to the distribution of the resistance adjustment voltage of ptc layer, when thereby the resistance of mode ptc layer is too small, because electric current is excessive and breakdown; By internal protective cover is set, can effectively prevent that cable is in folding process, the stress that inner discontinuity causes is concentrated; By heat-insulation layer is set, can effectively prevent that the functional layers such as internal protective cover of cable are overheated; By screen is set, can effectively reduce electromagnetic interference; By outer protective jacket is set, can effectively reduce wearing and tearing, improve the useful life of cable.
Accompanying drawing explanation
