Description
Technical field
The utility model relates to a kind of power cable more particularly to a kind of stretch-proof flame-proof power cables.
Background technique
Power cable is the cable for being used for transmission and distributing electric energy, and power cable is usually used in Urban Underground power grid, power station
Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line.Since power cable is in the basic routing line of electric system
In transmitting and distribute the cable product of high-power power, including 1-500KV and more than various voltage class, working environment
Badly, so insulation and flame-retardancy requirements to cable are higher than general cable, the power cable in currently available technology there is
Tensile resistance is general, poor flame retardant properties, high cost defect.In view of the foregoing drawbacks, it needs to be transformed the prior art.
Utility model content
The utility model aim is to provide a kind of stretch-proof flame-proof power cable, tensile resistance height, flame retardant property
It is good, and moderate cost.
A kind of stretch-proof flame-proof power cable, which is characterized in that it successively includes: an at least center conductor from inside to outside,
The center conductor includes the silicone insulation layer wrapped up outside core and core；One mica flame-retardant layer wraps up the center conductor；
One pvc sheath layer wraps up the mica flame-retardant layer.
Preferably, the silicone insulation layer is entwined by three layers of silicone band.
Preferably, the mica flame-retardant layer is entwined by three stratus master tapes.
Preferably, the pvc sheath layer is extruded by polyvinyl chloride.
Preferably, the core is twisted by seven copper cores, and seven copper cores are in 1+6 arrangement architecture and outer diameter ratio
3。
A kind of stretch-proof flame-proof power cable provided by the utility model, the silicone insulation layer are wound by three layers of silicone band
It forms, meeting makes center conductor more rounding under insulation conditions, to improve transmit electricity stability, tensile resistance；The mica is fire-retardant
Layer is entwined by three stratus master tapes, and the mica tape is resistant to 600~650 DEG C of high temperature, and the winding arrangement of three stratus master tapes can
To promote cable tensile resistance；The pvc sheath layer is extruded by polyvinyl chloride, and material cost is moderate；The line
Core is twisted by seven copper cores in 1+6 arrangement architecture, and outer diameter ratio is 3, and it is steady that such permutation and combination structure improves cable power transmission
It is qualitative.
Detailed description of the invention
Fig. 1 is a kind of stretch-proof flame-proof power cable structural schematic diagram that the utility model first embodiment provides；
Fig. 2 is that a kind of structure for stretch-proof flame-proof power cable center conductor that the utility model first embodiment provides is shown
It is intended to.
Specific embodiment
The embodiments described below are only the use of the new type a part of the embodiment, instead of all the embodiments.Base
In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts
There are other embodiments, fall within the protection scope of the utility model.
Refering to fig. 1, a kind of stretch-proof flame-proof power cable that the utility model first embodiment provides, in and it is outer successively
It include: four center conductors 3；Mica flame-retardant layer successively includes mica belt 23, mica belt 22, mica tape from inside to outside
Layer 21, mica flame-retardant layer 23 wraps up affiliated center conductor 3；One pvc sheath layer 1 wraps up affiliated mica flame-retardant layer 21.
Referring to Fig.2, a kind of stretch-proof flame-proof power cable center conductor 3 that the utility model first embodiment provides,
It from inside to outside once include: seven cores 34；Silica gel belt 33, silica gel belt 32, silica gel belt 31.
In the present embodiment, the silicone insulation layer is entwined by 33,32,31 3 layers of silica gel belt of silica gel belt, is met
Make the more rounding of center conductor 3 under insulation conditions, to improve transmit electricity stability, tensile resistance；The mica flame-retardant layer by 23,
22,21 3 stratus master tape layers are entwined, and the mica tape is resistant to 600~650 DEG C of high temperature, and the winding arrangement of three stratus master tapes
Cable tensile resistance can be promoted；The pvc sheath layer 1 is extruded by polyvinyl chloride, and material cost is moderate；Institute
It states core and is twisted by seven copper cores 34 in 1+6 arrangement architecture, and outer diameter ratio is 3, such permutation and combination structure improves cable
Transmission of electricity stability.
A kind of stretch-proof flame-proof power cable provided by the utility model, tensile resistance is high, flame retardant property is good, and at
This is moderate, can adapt to the severe use environment of power cable.
Above disclosed is only a kind of preferred embodiment of the utility model, and it is practical new cannot to limit this with this certainly
The interest field of type, therefore change on an equal basis made by present utility model application the scope of the patents, it still falls within the utility model and is covered
Range.
