1. there is the optoelectronic composite cable of special-shaped packing gasket, formed by two transmission of electricity unit, two fiber-optic signal transmission units, five special-shaped packing gaskets, protective layer, oversheaths;

  • The insulating barrier that transmission of electricity unit envelopes by power transmission conductor, by power transmission conductor forms;

    Fiber-optic signal transmission unit by optical fiber, envelope fibre-optic protection tube and form;

    Two transmission of electricity unit, two fiber-optic signal transmission units distribute around a special-shaped packing gasket, other four special-shaped packing gaskets lay respectively in four gaps of adjacent transmission of electricity unit, fiber-optic signal transmission unit and protective layer formation, protective layer envelopes two transmission of electricity unit, two fiber-optic signal transmission units, five special-shaped packing gaskets, and oversheath extrusion molding is coated on outside protective layer;

    It is characterized in that described special-shaped packing gasket by stiffener, be positioned at water blocking layer outside stiffener, be coated on the moisture vapor transmission layer outside water blocking layer, the outer water blocking layer being positioned at outside moisture vapor transmission layer forms, on moisture vapor transmission layer, have the moisture vapor transmission hole of water blocking layer and outer water blocking layer in multiple connections or described special-shaped packing gasket by stiffener, be positioned at water blocking layer outside stiffener, be coated on the moisture vapor transmission layer outside water blocking layer, the outer water blocking layer being positioned at outside moisture vapor transmission layer forms, and has the moisture vapor transmission hole of water blocking layer and outer water blocking layer in multiple connections on moisture vapor transmission layer;

    The material of outer water blocking layer is one side film waterstop, is to have multiple holes on waterstop, and overlay film face sticks on moisture vapor transmission layer;

    The material of interior water blocking layer is water blocking yarn, is to be closely wrapped in interior water blocking layer on stiffener or described to comprise by weight following raw material;

    polyacrylamide;

    50~

    80 parts, polyvinyl alcohol;

    10~

    30 parts, commercially available plastics antioxidant 1010 or 1076;

    0.6~

    1.2 part.
