Detailed description of the invention
As it is shown in figure 1, a kind of colliery stretch-proof insulated cable, it includes cable body 1,
Described cable body 1 includes conductor 2, enhancement Layer 3, screen layer 9 and oversheath 11, described
Cable body 1 is internally provided with multiple enhancement Layer 3；Described enhancement Layer 3 is internally provided with conductor
2；And described cable body 1 inner hub location arranges a guide core 5；Described enhancement Layer 3
Outer layer of metal braid 6 is set；Described wire sheathing 6 is outer closely extrudes layer protective layer
7；One layer of semiconductive lapping layer 8 is extruded outside described protective layer 7；Described semiconductive lapping layer 8
Extrude outward one layer of screen layer 9；One layer of stabilized zone 10 is extruded outside described screen layer 9；And described surely
One layer of oversheath 11 is extruded outside given layer 10.
Described conductor 2 uses bare copper wire material to make, and described bare copper wire material not only makes conductor 2
Conductivity is high, and material is the most soft, has preferable antioxygenic property；Described stretch-proof
Layer 4 not only increases the stretch-proof performance of cable body 1, and makes cable body 1 internal junction
Structure is the compactest；Described guide core 5 uses tinned copper wire braiding to form, it is possible to effectively stop
The interference that cable is caused by electromagnetic wave so that it is work process is more stable；Described wire sheathing
6 one aspects can play the effect strengthening uniform electric field, and another side can effectively strengthen cable
The mechanical strength of body 1；Described protective layer 7 uses Ceramic silicon rubber material to make, not only
There is high temperature resistant and fire-retardant characteristic, and there is preferable pliability, effectively enhance electricity
The practicality of cable body 1, extends the service life of cable；Described semiconductive lapping layer 8 can
As earth lead, cable is puncturing or during earth fault, and electric current can quickly introduce lowly,
Ensure the safety in colliery；Described screen layer 9 can reduce electric current and penetrate what screen layer 9 caused
Interference, reduces multiple reflections interference electromagnetic field, and the frequency making cable export changes or frequency ripple distortion
Reduce, reduce cable to outside interference；Described stabilized zone 10 is made for PE material,
There are preferable chemical stability and excellent dielectric properties, improve the dielectric properties of cable；
