Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment optical cable;
Fig. 2 is the structural representation of the utility model embodiment separator.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The flame-retardant fire-resistant four-in-one optical cable of the present embodiment, as depicted in figs. 1 and 2, four cable cores comprising inner sheath 3 and be arranged in inner sheath 3, four cable cores are respectively data copper cable 9, optical cable 10, radio frequency cable 11 and power cable 12, inner sheath 3 is embossing copper or stainless steel inner sheath, the periphery of every root cable core is enclosed with the insulating barrier 8 be made up of flame Retarding Polyvinyl Chloride Plastics, the inwall of inner sheath 3 is provided with fire-resistant isinglass belt 5, be filled with low smoke and zero halogen inserts 6 in the inner chamber of fire-resistant isinglass belt 5, cable core is embedded in this low smoke and zero halogen inserts 6; Inner sheath 3 is outer is provided with separator 2 and oversheath 1 successively.
In the optical cable of said structure, inner sheath 3 adopts the embossing steel or stainless steel inner sheath 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 cable core is enclosed with the insulating barrier 8 of flame Retarding Polyvinyl Chloride Plastics formation, improves flame retardant effect and the insulating properties of cable; In addition, be provided with fire-resistant isinglass belt 5 between the inwall of insulating barrier 8 and inner sheath 3, it has preferably fire resistance, improves the fire resistance of this optical cable; Again, in fire-resistant isinglass belt 5, be filled with low smoke and zero halogen inserts 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, inner sheath 3, for having set gradually separator 2 and oversheath 1, further enhancing the fire resistance of optical cable.
Wherein, separator 2 comprises the first glass fibre 13, ceramic fibre 14, second glass fibre 15, low smoke, zero halogen oxygen barrier layer 16 and the 3rd glass fibre 17 that set gradually from the inside to the outside, the Thickness Ratio of the first glass fibre 13, second glass fibre 15, the 3rd glass fibre 17 is 1:0.8 ~ 0.6:0.4 ~ 0.2, such as 1:0.5:0.3.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 16 not only further reduces the possibility producing pernicious gas when optical cable burns, and more enhances its fire resistance in addition.
Wherein, oversheath 1 is nylon inner restrictive coating and/or polyethylene inner restrictive coating, makes this optical cable have excellent resistance to wear and good corrosion resistance.
Wherein, the thickness of inner sheath 3 is 0.1 ~ 0.5mm, such as 0.2mm, 0.3mm, 0.4mm, and the thickness of oversheath 1 is 2.5 ~ 3.5mm, such as 2.7mm, 2.8mm, 3.0mm, 3.2mm.Adopt inner sheath 3 and the oversheath 1 of this thickness, best resistance to wear and fire resistance can be played simultaneously.
In order to firmly install the every position of root cable core in inner sheath 3, be provided with in criss-cross fixed mount 7 in the inner chamber of fire-resistant isinglass belt 5, data copper cable 9, optical cable 10, radio frequency cable 11 and power cable 12 are located between fire-resistant isinglass belt 5 and fixed mount 74 respectively in position, and low smoke and zero halogen inserts 6 is then filled in the space between fire-resistant isinglass belt 5, fixed mount 7, cable core three.When mounted, every root cable core is circumscribed with two adjacent poles of cross.
