Abstract
The invention relates to the technical field of cable equipment, and in particular relates to a fireproof cable. The fireproof cable comprises an inner core conductor, an inner filling layer, an inner knitting layer, a filling layer and a knitting layer; the inner core conductor is positioned in the fireproof cable; both the inner knitting layer and the knitting layer are knitted through quartz sand. According to the fireproof cable, the traditional copper sheath structure is changed, the problems like complex structure, inconvenient mounting, heavy structure and large bending radius of the traditional copper sheath are effectively solved, and a great significance; in addition, a heat sensing device arranged is convenient to monitor temperature on real time, and thus fire can be prevented.
Description
Technical field
The present invention relates to cable machinery technical field, be specifically related to a kind of fireproof cable.
Background technology
Cable industry is the second largest industry that China is only second to automobile industry, product variety meets rate and domestic market occupation rate all exceedes 90%, China's conduct is one of most important cable products research and development production base in the world, possess at present flame-retardant, high temperature resistant anti-low temperature, low inductance low noise, environmental protection, low smoke and zero halogen, anti-ant protection against rodents, a series of cable products with special performance and special construction such as waterproof and dampproof, and all formed certain productivity.
At present, along with improving constantly that society requires security protection guarantee and system safety, day by day increase especially fireproof cable accordingly for the requirement of cable.But fireproof cable of the prior art, overcoat adopts traditional copper jacket structure more, and this structure is not only wasted metals resources, with high costs, and weight increasing, affects the use of cable.Moreover this fireproof cable shock resistance is poor, bending difficulty, causes construction in fireproof cable installation process to be wasted time and energy, and easily causes potential safety hazard.The complicated trouble of last this fireproof cable preparation process, needs multistep welding, wastes time and energy.
Summary of the invention
The technical problem to be solved in the present invention is how to overcome the deficiency that prior art exists, and a kind of fireproof cable is provided.Product structure of the present invention is stable, bending radius is little, high temperature resistant, quality is light, cost is lower, easy to use.
Technical solution of the present invention is: a kind of fireproof cable, it is characterized in that: comprise interior core conductor, interior packed layer, interior braid, packed layer and braid, described interior core conductor is positioned at fireproof cable inside, described interior core conductor outside is interior packed layer, described interior braid is positioned at packed layer outside, described packed layer is positioned at braid outside, described packed layer is filled in whole fireproof cable, described braid is positioned at packed layer outside, wrap up whole packed layer, described interior braid and braid are quartz sand braiding.
Described interior core conductor is several.
Before described quartz sand braiding, smear fireproof paint, described interior braid and braid can directly be smeared fireproof paint.
Described interior braid and braid can be refractory material braiding, and described refractory material has vitreous silica, copper wire, asbestos, ceramic fibre, aluminosilicate refractory fiber.
Described packed layer is any one of fire-proof asbestos, rock wool or inserts.
Described inserts comprises talcum powder, agstone, calcium-magnesium powder, hydroxypropyl methylcellulose, adhesive, calcium stearate, tourmaline powder, diatomite composition.
Described packed layer inside is provided with thermal sensing device, described thermal sensing device monitor temperature, and when temperature is during higher than design temperature, described thermal sensing device sends temperature signal, sends related personnel to.
Described thermal sensing device is also provided with navigation system, is convenient to concrete location, monitoring temperature.
The invention has the advantages that product structure is stable, bending radius is little, high temperature resistant, quality is light, cost is lower, easy to use.The present invention be advantageous in that by increasing braid in quartz sand braid and quartz sand, fire resistance strengthens, can keep 1 hour at 800 degree high temperature, change traditional copper jacket structure, effectively change traditional copper jacket structure complexity, the problems such as constant, product structure is heavy, bending radius is large have been installed, huge to fireproof cable meaning.The present invention be advantageous in that thermal sensing device is installed, be convenient to real-time on-site monitoring temperature, the generation of fire preventing.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is embodiment of the present invention structural representation;
Fig. 2 is embodiment of the present invention sectional view;
Embodiment
Below, with reference to accompanying drawing, describe the embodiment of the present invention in detail.In addition, the present invention is not that this embodiment limits.
There is interior core conductor 1 middle part of the present invention, described interior core conductor 1 has three, packed layer 2 in interior core conductor coated outside one deck, braid 3 in interior packed layer 2 coated outside one decks, described interior braid 3 is formed by quartz sand braiding, material quality is lighter, and fire protecting performance is higher, and 800 degree high temperature can keep 1 hour.Described interior braid 3 outsides are filled with packed layer 4, and described interior packed layer 2 and packed layer 4 are fire-proof asbestos, described packed layer 4 coated outside one deck braids 5, and described braid 5 is to have quartz sand braiding to form equally.Before described quartz sand braiding, itself smear one deck fireproof paint, described interior braid 3 and braid 5 outsides are smeared one deck fireproof paint again, and bilayer is smeared, and has avoided the high temperature melting of interior braid 3 and braid 5.The present invention is also provided with thermal sensing device, described thermal sensing device 6 is installed on packed layer 4 inside, to responsive to temperature, when ambient temperature exceeds design temperature, described thermal sensing device 6 can send temperature signal to center service system, is convenient to related personnel's Real-Time Monitoring, and described thermal sensing device 6 is also equipped with navigation system, be convenient to related personnel's quick location, in time rescue.
