Abstract
The utility model discloses a fire-resistant optical cable. A plurality of optical cables are sheathed into one loosened sleeve, the loosened sleeve is internally filled with a waterproof filling material, the center of a cable core is a metal reinforcing core, the loosened sleeves and a plurality of fire-resistant filling ropes coated by a plurality of low-smoke zero-halogen sheaths enclose the metal reinforcing core to be stranded into a circular cable core, the gap in the cable core is filled with the water-proof filling material, and the cable core is externally and sequentially provided with a water-proof belt, a fire-proof glass cotton belt, an aluminum-plastic composite belt, a high-density polyethylene geomembrane and polyethylene inner sheath, a steel-plastic composite belt and a polyethylene outer sheath. The polyethylene outer sheath is externally coated with a layer of fire-proof coating layer. The fire-resistant optical cable has the improvement that a layer of low-density polyethylene geomembrane, the fire-proof glass cotton belt and the fire-proof coating are increased, so that the fire resistance is effectively improved, the fire-resistant optical cable can be preferably adapted to severe environment, and the long-distance paving of the fire-resistant optical cable can be performed.
Description
Technical field
The utility model relates to a kind of cable configuration, specifically is a kind of flame retardant type optical cable.
Technical field
GYTA53 type optical cable is because have advantages such as security performance is good, use cost is low, installation is simple, transmission range is long, information capacity is big, bandwidth is wide, volume is little, in light weight, obtained promoting widely and using, be widely used in long distance communication, interoffice communication, rugged surroundings etc.
The GYTA53 cable configuration is that optical fiber is inserted in the loose sleeve pipe that high-modulus makes, and fills the waterproof filling material in the loose sleeve pipe.The cable core center is one and covers poly metal strengthening core outward.The pine sleeve pipe is around the stranded conglobate cable core of center strengthening core compactness, the filling material that blocked water of the slit in the cable core.Extrude the layer of polyethylene inner sheath behind the vertical bag of plastic-coated aluminium strip APL, the vertical bag of two-sided plastic-coated steel band back is extruding the tygon oversheath, but the optical cable of this structure also has necessity of improving on fire resistance.
The utility model content
Technical problem to be solved in the utility model provide a kind of fire resistance good cable configuration.
Flame retardant type optical cable described in the utility model, it comprises optical fiber, some optical fiber are inserted in the loose sleeve pipe, in loose sleeve pipe, fill the waterproof filling material, the cable core center is a metal strengthening core, some loose sleeve pipes center on the stranded conglobate cable core of metal strengthening core with the fire-retardant gasket for packing that protects the low smoke and zero halogen sheath, slit in the cable core filling material that blocked water, outside cable core, set gradually water blocking tape, fire insulation glass strap, aluminium-plastic tape, high-density polyethylene geomembrane and tygon inner sheath, composite steel-plastic belt and tygon oversheath.
In order to improve fire protecting performance, can also smear one deck frie retardant coating layer in tygon oversheath outside.
Improvement of the present utility model is to have increased one deck low density polyethylene geomembrane, fire insulation glass strap and frie retardant coating.Low density polyethylene (HDPE) geomembrane has characteristics such as infiltration coefficient is low, density is big, thickness is even, adaptive temperature wide ranges, extensibility is big, flexibility good, dimensional stability is good; Fire insulation glass strap has characteristics such as toughness height, fire-retardant, heat absorption, oxygen barrier; Frie retardant coating contains the nanoscale magnesium oxide of 0.5%-5%, effectively raises fire protecting performance and wearing quality.The optical cable that has increased one deck high-density polyethylene geomembrane effectively raises anti-moisture vapor transmission ability, anti-lateral pressure resistant performance and stretch-proof performance.Increase one deck fire insulation glass cloth band and effectively raised the toughness of optical cable and fire-retardant energy.Shielding, wearing quality and fire retardancy that one deck frie retardant coating effectively raises optical cable have been increased.Can better adapt to rugged surroundings and long apart from laying.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of flame retardant type optical cable described in the utility model, its structure is: some optical fiber are inserted in the loose sleeve pipe 2, in loose sleeve pipe 2, fill the waterproof filling material, the cable core center is a metal strengthening core 3, some loose sleeve pipes center on metal strengthening core 3 stranded conglobate cable cores with the fire-retardant gasket for packing 5 that protects low smoke and zero halogen sheath 4, slit in the cable core filling material 6 that blocked water, outside cable core, set gradually water blocking tape 7, fire insulation glass strap 8, aluminium-plastic tape 9, high-density polyethylene geomembrane 10 and tygon inner sheath 11, composite steel-plastic belt 12 and tygon oversheath 13.Smear one deck frie retardant coating layer 14 in tygon oversheath 12 outsides.
The utility model provides a kind of thinking and implementation method of flame retardant type optical cable; concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
