Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Corrosion-resistant single core optical cable based on neoprene of the present embodiment, as depicted in figs. 1 and 2, the wire stylet 4 comprising inner sheath 3 and be arranged in inner sheath 3, inner sheath 3 is embossing copper or stainless steel inner sheath, the periphery of wire stylet 4 is enclosed with chloroprene rubber sheath layer 8, expanded polystyrene (EPS) protective sleeve 5 is provided with between the inwall of chloroprene rubber sheath layer 8 and inner sheath 3, be filled with brominated Polystyrene filler 6 in the inner chamber of expanded polystyrene (EPS) protective sleeve 5, wire stylet 4 is embedded in this brominated Polystyrene filler 6; Inner sheath 3 is outer is provided with separator 2, zinc-coated wire armour 1 and silicone rubber insulation layer 14 successively.
In the optical cable of said structure, inner sheath 3 adopts the embossing steel or stainless steel inner sheath 3 of rigidity, can strengthen the impact resistance of optical cable, extrusion performance, also have certain fire resistance, in addition, adopts embossing steel, is then conducive to bending; Secondly, the periphery of wire stylet 4 is enclosed with the chloroprene rubber sheath layer 8 of flame Retarding Polyvinyl Chloride Plastics formation, and have corrosion resistance and insulating properties, the setting of this layer enhances the corrosion resistance of optical cable simultaneously, improves tensile strength and the bending property of optical cable; In addition, be provided with expanded polystyrene (EPS) protective sleeve 5 between the inwall of chloroprene rubber sheath layer 8 and inner sheath 3, it has preferably fire resistance, improves the fire resistance of this optical cable; Again, in expanded polystyrene (EPS) protective sleeve 5, be filled with brominated Polystyrene filler 6, make because of fire cause optical cable to burn time, the smog of generation does not have toxic gas to produce, and avoids fire to cause secondary injury; Finally, set gradually separator 2, zinc-coated wire armour 1 and silicone rubber insulation layer 14 outside inner sheath 3, ensure that the decay resistance of optical cable.
Wherein, the thickness of zinc-coated wire armour 1 is 1.0 ~ 2.0mm, such as 1.0mm, 1.3mm, 1.5mm, 1.8mm, 1.0mm.In zinc-coated wire armour 1, zinc and iron and steel form primary cell, and zinc, as anode, prevents steel corrosion, and having the characteristics such as excellent anticorrosion, high strength, is outstanding waterproof, anticorrosive.
Wherein, separator 2 comprise set gradually from the inside to the outside the first glass fibre 9, ceramic fibre 10, second glass fibre 11, low smoke, zero halogen oxygen barrier layer 12 and the 3rd glass fibre 13, first glass fibre 9, second glass fibre 11, the 3rd glass fibre 13 Thickness Ratio be 1:0.8 ~ 0.6:0.4 ~ 0.2.Adopt the separator 2 of said structure, thickness relationship, optical cable can be made to have more excellent fire resistance, and the setting of low smoke, zero halogen oxygen barrier layer 12 not only further reduces the possibility producing pernicious gas when optical cable burns, and more enhances its fire resistance in addition.
Silicone rubber insulation layer 14 is 1.0 ~ 1.5:1, such as 1.2:1,1.3:1,1.5:1 with the Thickness Ratio of zinc-coated wire armour 1.Adopt silicone rubber insulation layer 14 and the zinc-coated wire armour 1 of this thickness relationship, can ensure that this optical cable has best corrosion resistance.
In order to the firm position of conducting wire core 4 in inner sheath 3; V-arrangement rubber skeleton 7 is provided with in the inner chamber of expanded polystyrene (EPS) protective sleeve 5; wire stylet 4 is arranged in the accommodation space inside this V-arrangement rubber skeleton 7, and accommodation space outside V-arrangement rubber skeleton 7, is filled with brominated Polystyrene filler 6 respectively between wire stylet 4 and V-arrangement rubber skeleton 7.In the present embodiment, V-arrangement rubber skeleton 7 is radial symmetric structure, and its angle is preferably 90 °.
