Description
Technical field
The utility model relates to a kind of cable, particularly a kind of novel shock resistance is high temperature resistant fire-resistant fluoroplastics cable.
Background technology
The fire resistance requirement that present fire-resisting cable generally can be up to state standards and stipulate, but all be to use in the normal temperature occasion, can not use at high temperature or low temperature situation, the actual conditions that can not correctly reflect the scene of fire, do not embody the influence of the impact of sandstone, current to fire-resisting cable, and the fire of reality not only has the bob thing, also has the impact of the current of fire-fighting, and general fire-resisting cable can not satisfy industrial needs at all.Therefore, the various cables with certain fire-resistant power after suitably improving on original cable basis have appearred, this class cable is mostly at coated outside one deck flame retardant coating of cable conductor, after flame retardant coating coated outside one layer insulating, add outer jacket, mainly be applicable to 0.6/1kV and following power transmission, fire-fighting and the computer supervisory control system that electric energy is provided for power, illumination etc., this cable has certain fire resistance, but still can not adapt to the operational environment requirement of adverse circumstances such as high temperature, powerful impact, can not satisfy industrial requirement.
Summary of the invention
The utility model is for solving above-mentioned deficiency of the prior art, provide a kind of shock resistance high temperature resistant fire-resisting cable, the utlity model has advantages such as good fire resistance energy, high and low temperature resistance, high-insulativity and working range are wide, and have very strong impact resistance.
The technical solution of the utility model has following content to be achieved:
The high temperature resistant fire-resisting cable of a kind of shock resistance comprises cable core and oversheath, it is characterized in that: set gradually high temperature resistant fire resistant flame retardant band, fire-retardant separator and shock resistance reinforced layer between described cable core and the oversheath from inside to outside; Described cable core is made of the conductor of filler that is positioned at high temperature resistant fire resistant flame retardant band and band protective layer, and the protective layer of described conductor respectively is refractory insulating layer, high temperature resistant fire resistant flame retardant layer, fluoroplastic insulation layer from inside to outside.
The described refractory insulating layer lap wound of attaching most importance to wraps in the outer double-deck fire-resistant isinglass belt of conductor.
Described high temperature resistant fire resistant flame retardant layer is a fiberglass layer.
Described filler is made of the glass material of high temperature resistant fire resistant flame retardant.
Described band is the wrapped glass fibre belt of double-layer overlapping.
Described separator is a high flame resistance, low smoke halogen-free polyolefin layer.
Described reinforced layer is steel-tape armouring layer or steel wire braid.
Described oversheath is the flame-retardant low-smoke halogen-free polyolefin jacket.
The beneficial effects of the utility model show following several aspect:
1, the high temperature resistant fire resistant flame retardant band of the utility model wrapped one deck on refractory insulating layer is as protective layer; outside the refractory insulating layer of big torch insulation burning back, also has the high temperature resistant fire resistant flame retardant band of one deck; this layer band mainly is to protect refractory insulating layer to have in the big fire combustion process under the impact of weighing down thing and fire-fighting current can not be damaged, and guarantees the normal operation of cable.
2, insulating barrier is a fluoroplastic insulation, because fluoroplastics long-term work temperature is more than 200 ℃, so this cable can be used for high temperature resistant fire-resistant occasion, and when breaking out of fire, fluoroplastics should have high fire resistance and can not prolong combustion, fully effectively protected the refractory insulating layer of the inside, played good fire-resistant effect, but under 180-200 ℃ of high temperature continuous operation 5-10; But long-term work in-60 ℃ of temperature simultaneously.
3, design has special separator and shock resistance reinforced layer between many eradication edge cores and oversheath; after cable is by flame combustion; separator becomes hard shell; under the protection of shock resistance reinforced layer, can not come off; fully effectively protected each insulated wire cores of cable at high temperature to be not easy burned; guaranteed the normal operation of cable, improved the reliability of cable greatly, for more time has been striven in fire-fighting and rescue.
4, the utility model is compared with common fire-resisting cable and not only can be used for a long time at high low temperature situation, but also has very strong impact resistance, the impact of current of having avoided weighing down thing, fire-fighting is to the influence of fire-resisting cable, guaranteed the normal operation of cable, improved the reliability of cable greatly, for more time has been striven in fire-fighting and rescue.The utility model is simple in structure simultaneously, is suitable for batch process, utilization and extention.
