Abstract
The utility model relates to a power cable, especially to a fire proof power cable. A plurality of conducting wires are disposed in the power cable, and the plurality of conducting wires, which are each wrapped with a mica tape fireproof layer, are clustered together. A silane crosslinked polyethylene insulating layer, a polyvinyl chloride isolation layer, a glass fabric belting layer and a polyvinyl chloride sheath layer are wrapped outside the clustered conducting wires. The material of the fireproof power cable is optimized while national requirements for fireproof cable are fulfilled, so that cable cost can be greatly reduced and the fireproof power cable can be widely popularized.
Description
Technical field
The utility model relates to a kind of electric wire, particularly a kind of fireproof power cable.
Background technology
Fire-resisting cable refers to can keep the cable of certain hour safe operation in the flame combustion situation.China's standard GB/T 12666.6 (waiting IEC331) is divided A, two kinds of ranks of B with fire resistance test, 950-1000 ℃ of A level flame temperature, continue for fire time 90min, 750-800 ℃ of B level flame temperature, continue for fire time 90min, whole duration of test, sample should bear the load voltage value of product regulation.Fire-resisting cable is widely used in skyscraper, underground railway, undergrond street, large-scale power station and the important places relevant with fire safety and fire-extinguishing and lifesaving such as industrial and mining enterprises.
Existing fireproof power cable complex structure causes cost high large.
The utility model content
The purpose of this utility model is to provide a kind of fireproof power cable cheaply.
The purpose of this utility model is achieved through the following channels: a kind of fireproof power cable, the built-in some conductors of this cable, the some conductor boundlings that are wrapped with the mica tape flame retardant coating together, its peripheral parcel organosilane crosslinked polyethylene insulation layer, polyvinyl chloride separator, glass wool cloth lapping layer and pvc sheath layer.
As the further optimization of scheme, described mica tape flame retardant coating is that the multilayer Mica tape is made.
As the further optimization of scheme, described conductor is two.
A kind of fireproof power cable of the utility model, draw materials meet national fire-resisting cable requirement fully in, optimize its material, greatly reduce cable cost, use suits large area to popularize.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
In figure, pvc sheath layer 1, glass wool cloth lapping layer 2, polyvinyl chloride separator 3, organosilane crosslinked polyethylene insulation layer 4, mica tape flame retardant coating 5, conductor 6.
Embodiment
As shown in Figure 1, its structure of a kind of fireproof power cable of the utility model is as follows, built-in 2 conductors of this cable, some conductor 6 boundlings that are wrapped with mica tape flame retardant coating 5 together, its peripheral parcel organosilane crosslinked polyethylene insulation layer 4, polyvinyl chloride separator 3, glass wool cloth lapping layer 2 and pvc sheath layer 1, described mica tape flame retardant coating 5 is made for the multilayer Mica tape.
