The method of preparing an opto-electric hybrid cable against bending and interference field

The present invention discloses an opto-electric hybrid cable against bending and one kind of interference field, which cable core comprises an insulating shield, drain wire, the load-bearing fibers, the optical unit, shield and outer sheath layer, the shield cable core insulation, drainage lines, optical fibers and load-bearing units are located in the outer jacket layer, shield layer is wrapped in an insulating shield cable core and the outer optical unit. The present invention also discloses the preparation of an interference field resistance to bending and opto-electric hybrid cable. Application of the aluminum composite tape as a shield layer in addition to prevent interference and crosstalk between the insulated wire, the insulation of the wire itself plays the role of interference; tensile strength of the pilot signal using the effective drainage line, the cable uses aramid substantial increase; using loose spiral steel armor layer protecting the optical effective means to prevent the cable being crushed and press-breaking, increase the bending ability of the cable. Such a configuration significantly to meet the requirements laid improved resistance to bending and anti-jamming capability, adapted to the requirements in field environment.
