Abstract
The utility model discloses a kind of plastic insulation to control cable, including 19 insulated wire cores, and described insulated wire cores divide three layers to be twisted into cable core in a manner of 1+6+12, and the gap of cable core extrudes inorganic hydration packed layer；In cable core outer cladding lapping layer, lapping layer is externally provided with metal screen layer, and plastics outer jacket is extruded outside metal screen layer；Described metal screen layer is made up of metal wire layer and metal tape；The lapping layer is prepared using dealcoholized type RTV silicon rubber as base rubber, using melamine phosphate as self-expanding fire retardant, using magnesium hydroxide as fire retardant and using synthetic fibers mesh grid as supporting body.The utility model earthed system is reliable, and shielding external interference effect is good, and flameproof effect is good.
Description
Technical field
It the utility model is related to field of cables, and in particular to a kind of plastic insulation controls cable.
Background technology
In cable using more and more frequently today, cable industry turn into the second largest row that China is only second to automobile industry
Industry, along with Chinese cable industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level obtains significantly
Improve, but still suffer from various shortcomings.The performance existing defects of existing control cable shield external interference.
With the development of skyscraper and the raising of fire-protection rating, and the reinforcement of people's awareness of safety, some buildings need
Higher voltage is transported at the top of building with fire-resisting cable.Because voltage is higher, traditional mica tape fire-resisting cable structure without
Method meets the design requirement of electric field in cable, is completely unsuitable for.Only design with the completely different knot of traditional fire-resisting cable
Structure could meet the requirement of electrical property and fire resistance simultaneously.
Traditional filling all has certain hygroscopicity, and the moisture after moisture absorption can corrode the insulating barrier of cable, reduces electricity
The electric property of cable.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, there is provided it is a kind of simple in construction, it is convenient for production,
Miscellaneous equipment need not be increased, the plastic insulation that production can be completed using existing equipment controls cable, its earthed system
Reliably, shielding external interference effect is good, and flameproof effect is good.
Technical scheme：To achieve the above object, the utility model provides a kind of plastic insulation control cable, including 19 thoroughly do away with
Edge core, described insulated wire cores divide three layers to be twisted into cable core in a manner of 1+6+12, and the gap of cable core extrudes inorganic hydration
Packed layer；In cable core outer cladding lapping layer, lapping layer is externally provided with metal screen layer, and plastics outer jacket is extruded outside metal screen layer；
Described metal screen layer is made up of metal wire layer and metal tape；The lapping layer using dealcoholized type RTV silicon rubber as base rubber, with
Melamine phosphate is self-expanding fire retardant, is used as supporting body using magnesium hydroxide as fire retardant and using synthetic fibers mesh grid
It is prepared.
Further, described insulated wire cores are made up of conductor and the plastic insulating layer being coated on outside conductor.
Further, the metal wire layer is made up of more one metal wires.
Compared with prior art, the beneficial effects of the utility model are：
1st, metal tape is provided below more one metal wires and forms metal screen layer by the utility model, can be had in construction and installation
Metal screen layer is accessed earth system by effect, and the effect of the earth is passed to so as to reach shielding interference signal and interference signal.
2nd, the inorganic hydration filling of extruding, can discharge a large amount of water when meeting fiery, and form non-burn-through mineral matter packed layer,
Preferably core is protected not to be burned.
3rd, the inorganic hydration filling of the utility model design adds the composite double layer fire insulation of the wrapped composition of ceramic silicone band
Type fire proof construction, make cable that there is good fire protecting performance, while also ensure that cable has excellent electric property.

As shown in figure 1, the utility model provides a kind of plastic insulation control cable, including 19 insulated wire cores, it is described
Insulated wire cores divide three layers to be twisted into cable core, the inorganic hydration packed layer 7 of gap extruding of cable core in a manner of 1+6+12；In cable core
Outer cladding lapping layer 3, lapping layer are externally provided with metal screen layer, plastics outer jacket 6 are extruded outside metal screen layer；Described metal screen
Layer is covered to be made up of metal wire layer and metal tape 5；The lapping layer using dealcoholized type RTV silicon rubber as base rubber, with melamine phosphoric acid
Salt is self-expanding fire retardant, is prepared using magnesium hydroxide as fire retardant and using synthetic fibers mesh grid as supporting body.
Described insulated wire cores are made up of conductor 1 and the plastic insulating layer being coated on outside conductor 2.The metal wire layer by
More one metal wires 4 are formed.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change
And improvement, these changes and improvements are both fallen within claimed the scope of the utility model.
