It covers and monitoring core conductor is woven outside layer；Inner sheath is extruded using Halogen EVA protective cover materials outside the master core and monitoring core,
One layer of aramid fiber braiding enhancement layer is woven outside inner sheath, extrudes one layer of oversheath outside aramid fiber braiding enhancement layer, oversheath is using low
Cigarette Halogen EVA protective cover materials.
Further, the power wire core conductor is twisted by tinned copper wire using regular structure.
Further, first insulating layer uses Halogen EPDM insulating materials.
Further, the second insulating layer uses Halogen EPDM insulating materials.
Further, it is led outside the second Halogen semiconductive shielding layer using aramid fiber and copper wire to weaving into monitoring core
Body.
Coal mine of the present invention monitors wrapping bag reinforced low smoke and zero halogen soft rubber cable with coal mining machine shield, employs new
Sheath material, i.e. low-smoke non-halogen flame-retardant EVA protective cover materials can improve the low cigarette of cable, Halogen, fire-retardant, less toxic performance.New electricity
Cable structure control core conductor center adds one aramid yarn, and aramid yarn and copper wire are used on its surface after control conductor extruded insulation
The mode of volume is woven, is used as monitoring core.This structure is by the control conductor of small bore and monitoring core processing one
It rises, increases the tension of control conductor and monitoring core, resistance to torsion ability, effectively both improved its service life.Restrictive coating uses
After extruding interior shield, weave one layer of aramid yarn braiding enhancement layer, after extrude outer shield, the entirety of cable can be effectively improved by this structure
Tensile capacity can effectively improve the service life of cable.
