Technical field
The present invention relates to a kind of power cable, be specifically related to a kind of fire-retardant fireproof power cable that under fire hazard environment, uses.
Background technology
At present, the structure of most of cables comprises conductor, mica tape, insulating barrier, filler, lapping layer and restrictive coating, the mica tape parcel invests the outside of conductor, insulating barrier is wrapped in the mica tape outside, filler is filled in the space of insulated wire cores, lapping layer is wrapped in into the outside of cable core, and restrictive coating is wrapped up in the outside that invests lapping layer, and sheath material mostly is the flame-proof PVC material.
In the cable use procedure, particularly under fire hazard environment, use a period of time after, the insulated wire cores of cable is destroyed soon, power breakdown, the very large hidden danger of having given people's Electrical Safety band.
Summary of the invention
For the deficiency that prior art exists, the object of the invention provides a kind of fire-retardant fireproof power cable, has improved the flame-retardant ability of cable under fire hazard environment, has improved simultaneously the usage safety performance of power cable, has reduced the operational failure rate of cable.
To achieve these goals, the present invention realizes by the following technical solutions:
The present invention includes many conductors, wrap up in the fire lagging, fire-retardant gasket for packing, aluminium-plastic tape separator and the flame retardant sheath layer that are attached to each conductor outside; Conductor and fire lagging consist of insulated wire cores, the aluminium-plastic tape separator is wrapped in the outside by the stranded cabling structure that forms of many eradications edge core, fire-retardant gasket for packing is filled in the space between fire lagging and the aluminium-plastic tape separator, and flame retardant sheath layer is located at the outer surface of aluminium-plastic tape separator.
The present invention is by the buffer action of fire lagging and aluminium-plastic tape separator, guaranteed that power cable is under Fire Conditions, the continued power of energy long period, strengthen the adaptive capacity to environment of cable, improved the fail safe of cable, expanded the usage space of cable, simplified the dependence of fireproof cable to fire-resistant isinglass belt, improved production efficiency, made the range of application of cable wider, adaptability is stronger.
The aluminium-plastic tape separator makes cable in fire hazard environment, can intercept cable external flame high temperature the long period to the erosion of inner electric component, has prolonged the power supply safety time.
What above-mentioned fire lagging specifically adopted is the pate dure insulating material.Insulating barrier is the fire-type insulating material, by the fire-type curable dielectric material, make cable under flame environment, insulating barrier forms the insulating material fireprotection layer of porcelain in hot conditions, the mica belt that has replaced common fire-resisting cable reaches more stable, lasting fire-resistant effect.
What above-mentioned flame retardant sheath layer specifically adopted is flame retardant polyolefine material.Adopt the fire retardant jacket material, further slowed down the destruction of flame to the cable internal structure, ensured to a greater extent the electrical continuity of cable.
The present invention is by the combining structure of fire lagging, aluminium-plastic tape separator and flame retardant sheath layer, substituted original Mica tape fireproof construction, reduced the production process of cable, improved the flame-retardant performance of cable, effectively reduce the loss of personnel and property under the fire hazard environment, improve the usage safety performance of power cable, prolonged the useful life of cable.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Referring to Fig. 1, the present invention includes many (at least two) conductors 1, wrap up in the fire lagging 2, fire-retardant gasket for packing 3, aluminium-plastic tape separator 4 and the flame retardant sheath layer 5 that are attached to each conductor 1 outside.
Conductor 1 consists of insulated wire cores with fire lagging 2, aluminium-plastic tape separator 4 is wrapped in the outside by the stranded cabling structure that forms of many eradications edge core, fire-retardant gasket for packing 3 is filled in the space between fire lagging 2 and the aluminium-plastic tape separator 4, and flame retardant sheath layer 5 is located at the outer surface of aluminium-plastic tape separator 4.
