Description
Technical field
The utility model relates to field of cables, and in particular to a kind of fireproof cable.
Background technique
Cable is widely used in power, communication transmission, and with the continuous development of technology, the applicable occasion of cable is more and more multiple
Hydridization, diversification are also higher to the performance requirement of cable.Currently, many cables are simple plus a fire prevention in terms of fire prevention
Insulation sleeve, there is easy firing, fire retardancy is weak, burning when the problems such as discharging a large amount of toxic gases.
Utility model content
Purpose of utility model: the utility model provides a kind of kind fireproof cable good with fire protecting performance, tensile strength is high.
The utility model provides a kind of fireproof cable, including six cable cores, each cable core successively include from the inside to the outside conductor,
Mica tape, polyester layer and fire prevention braiding layer；It further include an isolating frame, the isolating frame includes strengthening core and sets around strengthening core
Six spacers set, one end of each spacer are each attached on strengthening core, the cable core be placed in two neighboring spacer it
Between；Filled glass fiber layer between cable core and isolating frame, isolating frame successively coat oxygen barrier layer, flame-retardant layer, fireprotection layer and shield outside
The edge of jacket layer, the other end of spacer is respectively positioned in oxygen barrier layer.
Further, the conductor is formed by two and its two or more wire strandings.
Further, the angle between two adjacent spacers is 60 degree.
Further, the flame-retardant layer thickness is greater than 1mm.
Further, fireproof coating is coated in the fire prevention braiding layer.
The utility model has the advantages that the utility model effectively improves the tensile strength of cable by the way that isolating frame is arranged in cable；Pass through
Mica tape, polyester layer, fire prevention braiding layer, oxygen barrier layer, flame-retardant layer, fireprotection layer are set, so that cable has good fire protecting performance.
Detailed description of the invention
Fig. 1 is the utility model high-temperature cable structural schematic diagram.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate.
The utility model proposes a kind of fireproof cables, as shown in Figure 1, include six cable cores, each cable core from the inside to the outside according to
Secondary includes conductor 1, mica tape 2, polyester layer 3 and fire prevention braiding layer 4；Wherein conductor 1 is twisted by multiple conducting wires, and conducting wire is
Copper conductor or corronil conducting wire；Mica tape 2 and polyester layer 3 are by flame-retarding characteristic, and braiding layer 4 of preventing fires is by ceramic plastics
Silk and aramid fiber vertical woven form, it is preferable that are coated with fireproof coating in fire prevention braiding layer 4.
Fireproof cable further includes an isolating frame, isolating frame 5 include a strengthening core 6 and be arranged around strengthening core 6 six every
From piece 7, one end of each spacer 7 is each attached on strengthening core 6, and the edge of the other end of spacer 6 is respectively positioned on oxygen barrier layer 9
On, the angle between two adjacent spacers 7 is 60 degree, and strengthening core 6 and spacer 7 are that metal material is made, and cable core is set
Between two neighboring spacer 7, isolating frame 5 separates each cable core, so that after cable is on fire, it will not be in a short time
All failures on fire, can effectively reduce fire damage caused by cable, while enhancing the tensile property of cable.
The flexibility of cable can be improved in filled glass fiber layer 8 between cable core and isolating frame 5, glass layer 8, simultaneously
Improve fireproofing of cable performance；Oxygen barrier layer 9, flame-retardant layer 10, fireprotection layer 11 and restrictive coating 12 are successively coated outside isolating frame 5；Every
Oxygen layer 9 is Ceramic silicon rubber or low smoke and zero halogen material or PVC material, and cable core and extraneous oxygen obstruction are worked as generation by oxygen barrier layer 9
When fire, prevent flame enter cable core, avoid cable core from being destroyed, prevent circuit occur open circuit, short circuit, fire occur when after
Ability to transmit electricity is held in continuation of insurance；Flame-retardant layer 10 is low smoke, zero halogen polyolefin, and toxic gas will not be generated burning, and flame-retardant layer 10 is thick
Degree is greater than 1mm；Fireprotection layer 11 is inorganic staple fiber viscose glue fireprotection layer or inorganic mineral fireprotection layer；Restrictive coating 12 be metal or
Low smoke and zero halogen material.
The utility model effectively improves the tensile strength of cable by the way that isolating frame is arranged in cable；By the way that mica is arranged
Band, polyester layer, fire prevention braiding layer, oxygen barrier layer, flame-retardant layer, fireprotection layer, so that cable has good fire protecting performance, it is fiery when occurring
When calamity, it still is able to transmit electric power.
