Abstract
The utility model relates to a communication cable for a halogen-free low-smoke flame-retardant fire-proof ship. The communication cable is characterized in that single insulating wire core is formed by sequentially lapping a mica tape I (2) and an extruded crosslinked polyethylene insulating layer (3) outside a tin-plated copper conductor (1), single shielded wire pair is formed by twisting a plurality of insulating wire cores and sequentially lapping a polyester tape (4) and a copper wire braiding pair shielding layer (5), a plurality of shielded wire pairs are twisted to form a cable core, and filling layers (6) are arranged at clearance of the main cable core; and a mica tape II (7), a halogen low-smoke flame-retardant wrapping tape (8), an internal sheath (9), a total copper wire braiding shield (9) and an external sheath are coated outside the main cable core in sequence. The cabling lapping adopts a composite structure of one mica tape layer and one halogen-free low-smoke flame-retardant wrapping tape layer, the halogen-free low-smoke flame-retardant wrapping tape plays a role in protecting the mica tape, and the fire resistance property and the flame retardance property of the cable can be enhanced; and by adopting a copper wire braiding pair shield and main shield manner, the cable has good shielding performance and anti-interference property, and the shielding performance of the cable can be greatly improved.
Description
Technical field
The utility model relates to a kind of cable, particularly LSOH anti-flaming fire resistant ship telecommunication cable; Belong to technical field of electric wires and cables.
Background technology
Along with socioeconomic development, the electric wire consumption increases rapidly, the electrical fire accident also occurs again and again, people are from the heaviness lesson of electrical fire accident, recognize gradually at some important places, as electric equipments in the circuits such as naval vessel, production platform, petroleum chemical enterprise, large-scale power station, large-scale command and control center and skyscraper, underground structure, tunnel, subway, it is very important keeping being in stable running status in certain hour under fire condition.
At present, along with improving constantly of scientific and technological level, fire-retardant problem further develops fire-retardantization of low halogen, Halogen by the halogen flame retardant in past.How further to improve the anti-flammability of cable and mechanical performance thereof and electric property and be and instantly need the difficult problem that solves.
The utility model content
The deficiency that the utility model exists in order to overcome prior art provides a kind of LSOH anti-flaming fire resistant ship telecommunication cable, and it not only has good fire protecting performance and fire resistance, and has good shielding properties and interference free performance.
The utility model technical solution problem adopts following scheme:
LSOH anti-flaming fire resistant ship telecommunication cable, its design feature is, by tinned copper conductor outward successively wrapped mica tape one, extrude crosslinked polyetylene insulated layer and consist of single insulated wire cores, edge cores wrapped polyester belt, the proof copper-wire braided sub-shields successively after stranded thoroughly done away with more, consist of single shielded pair, the stranded rear formation cable core of a plurality of shielded pairs, the gap between described shielded pair is provided with packed layer; Total cable core is provided with mica tape two, LSOH anti-flaming band, inner sheath, the total screen of proof copper-wire braided outward successively, and oversheath.
The utility model design feature also is:
The count of described proof copper-wire braided sub-shield and the total screen of proof copper-wire braided is all greater than 85%.
Described inner sheath adopts the low cigarette polyolefin material of irradiation crosslinking halogen-free, and described oversheath adopts low smoke, zero halogen polyolefin material.
Described packed layer adopts glass cord to fill.
The utility model beneficial effect is embodied in:
1, the utility model cable insulation material, packing material, band material and sheath material are all not halogen-containing, cable still can keep good insulation property in the high-temp combustion situation, can move continuously in thermal-flame, can not produce pernicious gas and a large amount of smog when burning, not exist and to cause " secondary disaster ".
2, the utility model stranding wrapped employing one deck mica tape and one deck LSOH anti-flaming band composite construction; mica tape adopts overlapping wrapped form; the overlapping wrapped rate of mica tape is more than 35%; the LSOH anti-flaming band plays the effect of protection mica tape; prevent that in cable bend, the female powder of mica tape medium cloud comes off, improve simultaneously fireproofing of cable performance and fire resistance.
3, the utility model adopts proof copper-wire braided separated-shielding and total shielding pattern, and the count of shielding has good shielding properties and interference free performance greater than 85%, has improved greatly the shielding properties of cable.
Description of drawings
Fig. 1 is the utility model construction of cable schematic diagram.
Number in the figure: 1 tinned copper conductor, 2 mica tapes one, 3 crosslinked polyetylene insulated layers, 4 polyester belts, 5 proof copper-wire braided sub-shields, 6 packed layers, 7 mica tapes two, 8 LSOH anti-flaming bands, 9 inner sheaths, the 10 total screens of proof copper-wire braided, 11 oversheaths.(wherein mica tape one and mica tape two all refer to mica tape)
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, the interior flame retardant coating that formed by tinned copper conductor 1, mica tape 1 of the utility model cable, crosslinked polyetylene insulated layer 3, polyester belt 4, proof copper-wire braided sub-shield 5, packed layer 6; The outer flame retardant coating 7 that mica tape 27 forms; LSOH anti-flaming band 8, the low cigarette polyolefin material inner sheath 9 of irradiation crosslinking halogen-free, the total screen 10 of proof copper-wire braided; The low cigarette polyolefin material oversheath 11 of irradiation crosslinking halogen-free forms.
In concrete enforcement, tinned copper conductor 1 adopts restraints the structure that tangles, the interior flame retardant coating that wrapped two-layer mica tape 1 forms on conductor, and crosslinked polyetylene insulated layer 3 extrudes on mica tape one, and adopts vapor crosslinking; Two thoroughly do away with edge core pair twist, then wrapped polyester belt 4, form proof copper-wire braided sub-shield 5 at polyester belt braiding brass wire shielding, then a plurality of shielded pairs twist together the formation cable core, the gap of shielded pair is that packed layer 6 adopts glass cord to fill, the outer wrapped one deck mica tape 7 of cable core and one deck LSOH anti-flaming band 8(glass fibre band), extrude the low cigarette polyolefin inner sheath 9 of irradiation crosslinking halogen-free on band; The total screen 10 of proof copper-wire braided, low smoke, zero halogen polyolefin jacket 11 extrude moulding.
The utility model cable still can keep good insulation property in the high-temp combustion situation, can move continuously in thermal-flame, can not produce pernicious gas and a large amount of smog when burning, does not exist and can cause " secondary disaster ".Have good shielding properties and interference free performance, improved greatly the shielding properties of cable.
