Abstract
The utility model discloses a kind of fire-alarming cables, including there are three cores, each core includes conductor one and conductor two, insulating layer is coated in the outside of conductor one, by conductor one, it is successively coated with nano-silicon marine glue filled layer on the outside after a conductor two and round polyester material tear rope is twisted, aluminum foil mylar belt and kevlar fiber braiding layer, fiber filament burr is equipped on the outer surface of kevlar fiber braiding layer, plating Silver alloy wire woven shield is successively coated with after three cores are twisted on the outside, the composite filled layer of pearlife, Ceramic silicon rubber fire resisting fireprotection layer and cold-resistant butyronitrile external sheath layer.The utility model cable conductor uses copper covered steel conductor, and tension has relatively high mechanical strength；It is equipped with fiber filament burr on the outer surface of kevlar fiber braiding layer, the friction between core can be increased, be unlikely to deform, it is heat-insulated, cold-resistant, flameproof effect is good.
Description
Technical field
The utility model relates to field of cable technology more particularly to a kind of fire-alarming cables.
Background technique
Cable is usually by several or the cable of at least two similar ropes being twisted of several groups of every group of conducting wires, and every group is led
Mutually insulated between line, and being often twisted into around a center, entire outside are surrounded by the coating of high-insulation, be by electric power or
Information is transferred to the conducting wire at another place from one.
Alarm system is mainly used for the transmission of warning message with cable.Existing alarm system cable high temperature resistant and cold-resistant
Performance is not strong, and between its inner conductor there is gap to easily deform in practical work process.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of fire-alarming cable.
The utility model is achieved through the following technical solutions:
A kind of fire-alarming cable, including there are three core, each core includes conductor one and conductor two, in conductor one
Outside be coated with insulating layer, by conductor one, a conductor two and round polyester material tear rope it is twisted after successively wrap on the outside
It is covered with nano-silicon marine glue filled layer, aluminum foil mylar belt and kevlar fiber braiding layer, in the appearance of kevlar fiber braiding layer
Face is equipped with fiber filament burr, is successively coated with plating Silver alloy wire woven shield, pearly-lustre after three cores are twisted on the outside
The composite filled layer of sand, Ceramic silicon rubber fire resisting fireprotection layer and cold-resistant butyronitrile external sheath layer.
The conductor one and conductor two is copper covered steel conductor.
The insulating layer be ethylene-vinyl acetate copolymer insulating layer, polyethylene layer, polystyrene insulation layers and
One of modified polystyrene insulating layer.
The conductor one and conductor two of cable are separately connected the anode and cathode of alarm power supply, when a fire, low melting point
Insulating materials melt, the anode and cathode contact of conductor, fire-alarm sounds an alarm.
The utility model has the advantages that: the utility model cable conductor uses copper covered steel conductor, and tension has relatively high machine
Tool intensity；It is equipped with fiber filament burr on the outer surface of kevlar fiber braiding layer, the friction between core can be increased, it is not variable
Shape is successively coated with plating Silver alloy wire woven shield, the composite filled layer of pearlife, ceramics on the outside after being twisted three cores
SiClx rubber fire resisting fireprotection layer and cold-resistant butyronitrile external sheath layer, it is heat-insulated, cold-resistant, flameproof effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of fire-alarming cable, including there are three core, each core includes conductor 1 and conductor
22, it is coated with insulating layer 3 in the outside of conductor 1, conductor 1, conductor 22 and a round polyester material tear rope 4 are twisted
Nano-silicon marine glue filled layer 5, aluminum foil mylar belt 6 and kevlar fiber braiding layer 7 are successively coated with after conjunction on the outside, in triumphant cottonrose hibiscus
It draws the outer surface of fiber braiding layer 7 to be equipped with fiber filament burr 8, is successively coated with silver-plated conjunction on the outside after three cores are twisted
The composite filled layer 10 of spun gold woven shield 9, pearlife, Ceramic silicon rubber fire resisting fireprotection layer 11 and cold-resistant butyronitrile external sheath layer
12。
The conductor 1 and conductor 22 is copper covered steel conductor.
The insulating layer 3 is ethylene-vinyl acetate copolymer insulating layer, polyethylene layer, polystyrene insulation layers
One of with modified polystyrene insulating layer.
The conductor 1 and conductor 22 of cable are separately connected the anode and cathode of alarm power supply, when a fire, eutectic
The insulating materials of point melts, and the anode and cathode contact of conductor, fire-alarm sound an alarm.
