Abstract
The utility model discloses a low-smoke halogen-free flame-retardant fireproof communication cable for ships, which comprises a second kind of tin-coated copper flexible conductor. A low-smoke halogen-free flame-retardant ceramic silicone rubber fireproof layer and an irradiation crosslinked polyethylene insulating layer are successively coated outside the tin-coated copper flexible conductor. After two conductors are intertwisted, a tin-coated copper wire woven sub-shielding layer, an irradiation crosslinked high-flame-retardance low-smoke halogen-free insulation shielding insulating layer and an EP rubber insulating layer are successively coated outside. After two wire cores are intertwisted, a radiation crosslinked high-flame-retardance halogen-free low-smoke inner sheath, a tin-coated copper wire woven total shielding layer, a waterproof canvas winding layer and a radiation crosslinked high-flame-retardance halogen-free low-smoke sheath are successively coated outside. The low-smoke halogen-free flame-retardant fireproof communication cable provided by the utility model has advantages of: high fireproof performance, small weight, small outer diameter, low-smoke halogen-free flame-retardant property, high moisture resistance, high bending performance, high flame retardance, and high flexibility.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of naval vessel low smoke halogen-free fire retardant fire resistant telecommunication cable.
Background technology
Present naval vessel is all wrapped cloud bar on conductor with low smoke halogen-free fire retardant fire resistant telecommunication cable substantially, when Mica tape, the cross section of conductor is little, must use special-purpose fire-resistant lapping equipment, when wrapped, also exist be difficult for wrapped smooth, even subsides, closely, adding mica is a kind of fragility material, walk around in journey the careless slightly mica that will cause wrinkling and broken, cause ND spark to hit ignore, for the safe handling of cable later causes great hidden danger, and cable also cannot be by the fire resistance test of national Specification, because cross-sectional area of conductor is less and soft, employing ordinary mica tape is wrapped, even if adopting special-purpose fire-resistant lapping equipment is also to produce, the situation that this just causes fire-resistant cable with small cross section to produce.Even wrapped, get on, when its cable is used on naval vessel, due to salt fog and moisture larger, mica tape is when running into salt fog and moisture, its insulation property can variation, even there is no insulation property, makes the fire-resistant disabler of cable.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of naval vessel low smoke halogen-free fire retardant fire resistant telecommunication cable is provided.
The utility model is achieved through the following technical solutions:
A kind of naval vessel low smoke halogen-free fire retardant fire resistant telecommunication cable, include the 2nd class tin-coated copper flexible conductor, in the outside of described conductor, be coated with successively low-smoke non-halogen flame-retardant ceramic silicon rubber flame retardant coating and IXPE insulating barrier, tinned copper wire woven separated-shielding layer will be coated with successively in outside after two conductor pair twists, between cross-linking radiation high flame resistance, low smoke Halogen insulation shielding, separator and ethylene propylene rubber insulated layer form core, cross-linking radiation high flame retardant low smoke, zero halogen inner sheath will be coated with successively in outside after two core pair twists, tinned copper wire braided overall-shielding layer, Tarpauling lapping layer and cross-linking radiation high flame retardant low smoke, zero halogen sheath.
Conductor is to adopt the stranded flexible conductor of zinc-plated oxygen-free copper the 2nd class, to improve flexibility and the bending property of cable, adopts tinned conductor to improve the resislance to corrosion from sea water of cable.
What flame retardant coating adopted is low-smoke non-halogen flame-retardant ceramic silicon rubber, and it is high that this refractory material has heatproof, good insulation preformance, and water resistant and humidity resistance are high, can extrude continuously and characteristic convenient for production.
What insulating barrier adopted is IXPE insulation, and this material has long-term high temperature resistant 125 ℃, and low temperature resistant-40 ℃, dielectric constant are little, the characteristic of low smoke and zero halogen.
Sub-shield and total screen adopt tinned copper wire braid shielded, and its shielding density is not less than 90%, adopts tinned copper wire braid shielded can improve the resislance to corrosion from sea water of cable shield, adopts high shielding rate can improve anti-interference and the confidentiality of cable.
Between shielding, separator adopts cross-linking radiation high flame resistance, low smoke Halogen insulating material, to improve the fire resistance of cable, insulation property and the heat resistance between shielding.
Inner sheath and oversheath adopt cross-linking radiation high flame retardant low smoke, zero halogen protective cover material, to improve fire resistance and the thermal endurance of cable.
The utility model has the advantages that: it is good, lightweight to the utlity model has fire resistance, and external diameter is little, low-smoke non-halogen flame-retardant, humidity resistance is good, and bending property is high, and fire resistance is high, the advantage that softness is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of naval vessel low smoke halogen-free fire retardant fire resistant telecommunication cable, include the 2nd class tin-coated copper flexible conductor 1, in the outside of described conductor 1, be coated with successively low-smoke non-halogen flame-retardant ceramic silicon rubber flame retardant coating 2 and IXPE insulating barrier 3, to after two conductor 1 pair twists, in outside, be coated with successively tinned copper wire woven separated-shielding layer 4, between cross-linking radiation high flame resistance, low smoke Halogen insulation shielding, separator 5 and ethylene propylene rubber insulated layer 6 form core, cross-linking radiation high flame retardant low smoke, zero halogen inner sheath 7 will be coated with successively in outside after two core pair twists, tinned copper wire braided overall-shielding layer 8, Tarpauling lapping layer 9 and cross-linking radiation high flame retardant low smoke, zero halogen sheath 10.
