Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model be to provide a kind of produce less smog when possessing high environmental-protecting performance, burning and do not produce harmful hydracid material, have good anti-ant mouse performance, fire resistance, footpath axially block-water performance and the high cable of mechanical strength.
The utility model technical solution problem adopts following technical scheme:
Nanoscale level modification filled polyolefin environment-friendly cable, the stranded formation cable cores of edge core that thoroughly do away with more, be provided with packed layer in the cable core gap, described insulated wire cores from-inner-to-outer is made of conductor, the wrapped flame retardant coating of mica and insulating barrier, described insulating barrier adopts nanoscale level modification filled polyolefin to make, and is coated with the polypropylene tape that blocks water, halogen-free glass fiber band, mica tape flame retardant coating, oxygen barrier watertight composition, galvanized steel strip armour and restrictive coating outside described cable core and packed layer successively.
Described packed layer is the polypropylene yarn packed layer that blocks water.
Described restrictive coating is nano level modified filled polyolefin sheath.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Conductor adopts the tin-coated copper core conductor of the 5th class, can prevent the corrosion of moisture content and other harmful substance; Insulating material adopts nano level modified filled polyolefin to make, this material not only has the superior electrical property of polyethylene, and compare with common polythene, its mechanical performance is improved greatly, especially tensile strength is tens times of common polythene, the environmental stress resistance performance of this material also improves a lot in addition, common polythene material environmental stress resistance performance is poor, the insulation cracking phenomena in use appears easily, but the environmental stress resistance performance of this new material obtains very big improvement, avoided cable the phenomenon that insulate and ftracture, the useful life of having improved cable greatly in use to occur; Packed layer and its outer block water polypropylene yarn and polypropylene tape of adopting, water absorption capacity surpasses 70ml/g, prevents that effectively moisture from immersing; The oxygen barrier damp-proof layer adopts the low-smoke halogen-free polyolefin of high oxygen index, and this material oxygen barrier index reaches 50%, and has humidity resistance; Armour adopts stainless steel wire, steel-tape armouring, this material has high corrosion resistance and compares its corrosion resistance with common galvanized steel strip or plating lacquer steel band and improve greatly, the machine alkali stretching resistance and the compressive resistance of steel band are also higher, can bear the mechanical force that comes from the outside in the cable use, this material also is a nonmagnetic substance in addition, the magnetic hysteresis loss of having avoided cable in use to produce has improved the bearing capacity of cable; Restrictive coating adopts the modification of nanoscale level to fill anti-ant mouse polyolefine material; this material adopts the termite-resistant rodent-resistant repellant that extracts from multiple natural plants; after repeatedly compound, add in the cable sheath material; make cable jacket contain a kind of specific peculiar smell; because of being upset, its sense of smell detests and rejects contact behind the mouse ant class animal contact cable; also can send impalpable information and produce population effect simultaneously, thereby reach the purpose that the protection cable is not destroyed by the mouse ant to colony.Smoke density was very low when the utility model product had burning, non-corrosiveness gas is overflowed, do not produce harmful hydracid material yet, termite-proof and mouse bites, possesses axially waterproof of footpath simultaneously, high flame retardant and fire-resistant, advantages such as insulation mechanical strength height and environmental stress resistance performance are strong, and multiple performance such as the little bearing capacity of cable loss is strong, can be widely used in nuclear power station, the subway station, telephone exchange and computer controlling center, the skyscraper building, the hotel, TV and Radio Service, hospital, office building, important military installations, oil platform etc., and the concentrated place of personnel, also be extensive use of in China temperate zone and subtropical zone many mouse ant area.In a word, this utility model product be a kind of with environmental protection, block water, anti-ant mouse, fire-retardant, fire-resistant, new product that security performance is integrated in one such as mechanical strength is high, bearing capacity is strong, vast market prospect is arranged.
