Abstract
The invention discloses a fireproof high-temperature-resistant power cable with excellent fireproof performance. The center of the fireproof high-temperature-resistant power cable is provided with an alloy copper conductor, a silicon carbide insulation layer is extruded outside the alloy copper conductor, and an inner jacket and an outer jacket are sequentially arranged outside the silicon carbide insulation layer. The inner jacket is a welding copper pipe, and the outer jacket is co-extruded by a PP (Propene Polymer) copolymer.
Description
?
Technical field
The present invention relates to a kind of cable, be specially a kind of fire-proof high-temperature resistant power cable.
Background technology
In social life, fire is to threaten public safety, one of disaster of harm people lives and properties.Now, fire is the common wicked problems that the people of other countries face.It caused the heavy losses of many life, property to human society.Along with development of social productivity, the wealth of society increases day by day, and fire damage rises and the general trend of fire hazard expanded range is an objective law.Yet common power cable heatproof is low, and fire protecting performance is poor, has brought a lot of inconvenience for the fire prevention rescue work.
Summary of the invention
The present invention seeks to deficiency, provide a kind of fire protecting performance good power cable to the prior art existence.
A kind of fire-proof high-temperature resistant power cable of the present invention, cable center is the alloyed copper conductor, outside the alloyed copper conductor, extrudes the carborundum insulating barrier, the carborundum insulating barrier is provided with inner sheath and oversheath outward successively.
Said inner sheath is welding copper pipe, the oversheath that oversheath extrudes for the PP copolymer.
Beneficial effect of the present invention:
1, adopts the alloyed copper conductor, compare common material and when burning, be difficult for oxidation.
2, with carborundum extruded insulation layer, better than originally with magnesia filling resistance to elevated temperatures, improve effect, save time.
3, the fire protecting performance grade is high, and power-up period is long.
4, it is good to manage and protect the cover fire protecting performance with soldering copper.
5, protect oversheath in work progress and after laying with PP copolymer sheath, when burning, can not produce poisonous and hazardous gas.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.Only be used for and be not limited only to scope of the present invention.
Like Fig. 1, a kind of fire-proof high-temperature resistant power cable of the present invention, its, cable center is an alloyed copper conductor 1, outside alloyed copper conductor 1, extrudes carborundum insulating barrier 2, is provided with the oversheath 4 that welding copper pipe inner sheath 3 and PP copolymer extrude outside the carborundum insulating barrier 2 successively.
The maximum operation (service) temperature of silicon carbide fibre reaches 1200 ℃, and its thermal endurance and oxidative resistance all are superior to carbon fiber, and intensity reaches 1960～4410MPa, and strength retention is more than 80% under maximum operation (service) temperature, and modulus is 176.4～294GPa, and chemical stability might as well.Mainly as exotic material and reinforcing material, exotic material comprises the filter cloth of heatshield material, high temperature-resistance conveyor belt, filtration high-temperature gas or motlten metal etc. to silicon carbide fibre.When being used as reinforcing material, normal share, can use 90 minutes, maintain and give fire-fighting, lifesaving appliance and security system supply electric energy under the fire situation, rescue difficulty with reducing to reduce casualties at 1200 ℃ with carbon fiber or glass fiber.
The concrete application approach of the present invention is a lot, and the above only is a preferred implementation of the present invention, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
Claims (3)
1. a fire-proof high-temperature resistant power cable is characterized in that, cable center is alloyed copper conductor (1), outside alloyed copper conductor (1), extrudes carborundum insulating barrier (2), outer inner sheath (3) and the oversheath (4) of being provided with successively of carborundum insulating barrier (2).
2. fire-proof high-temperature resistant power cable according to claim 1 is characterized in that, said inner sheath (3) is the welding copper pipe.
3. fire-proof high-temperature resistant power cable according to claim 1 and 2 is characterized in that, the oversheath that said oversheath (4) extrudes for the PP copolymer.
