Description
Technical field
The utility model relates to a kind of retardant cable of locomotives, particularly a kind of high ferro and city rail cable for rolling stock.
Background technology
Along with the fast development of China Express Railway and urban track traffic, high ferro and city rail cable for rolling stock used, its operational environment and fail safe have determined the particularity of the cable that uses, and require the performances such as Halogen, low cigarette, fire-retardant, low toxicity, oil resistant, high-low temperature resistant, environmental protection.The insulating barrier of cable for rolling stock and restrictive coating great majority adopt Halogen cross-linked polyolefin material or mixed rubber material at present, due to Halogen cross-linked polyolefin or mixed rubber during as insulating material, its electric property is poor, insulation resistance is low, especially rubber composition contains fluorine, the harmful substances such as chlorine, when burning, produce a large amount of dense smoke, dioxin, the public hazards materials such as acid gas, if product is for high ferro and the intensive public place of city rail personnel, to jeopardize life and public safety, can not meet the demand for development of high-speed railway and urban track traffic, cable for rolling stock is needed to further promote its various performances meets the need of market.
Utility model content
The purpose of this utility model is to provide a kind of high ferro and city rail cable for rolling stock, make it have the characteristics such as oil resistant, high-low temperature resistant, acid and alkali-resistance, resistance to ozone, floride-free halogen-free flame-proof environmental protection, can adapt to high ferro and city gage locomotive vehicle rugged environment, and there is Environmental Safety.
The technical solution of the utility model is such: a kind of high ferro and city rail cable for rolling stock, comprise conductor, interior insulation, external insulation, inner covering, shielding and sheath, it is characterized in that: coated interior insulation and external insulation form insulated wire cores to conductor successively outward, after some insulated wire cores are stranded, be coated successively inner covering, shielding and sheath, described conductor is the zinc-plated stranded annealed copper wire of multiply, described interior insulation is Polyetherimide insulation, described external insulation is floride-free non-halogen flame-proof cross-linking polyolefin insulation, described inner covering is Halogen polyester band, described shielding is tinned copper wire braid shielded, described sheath is floride-free non-halogen flame-proof cross-linking polyolefin jacket.
Described conductor is bundle strand or the structure that tangles again, and bundle strand pitch is 16～20 times of conductor diameter, and twisting again outer pitch is 10～14 times of conductor diameter.
Described interior insulation is extrusion type Polyetherimide insulating material, specific insulation 1016 Ω .m.
Described external insulation and sheath are respectively the floride-free non-halogen flame-proof cross-linking polyolefin insulation of extrusion type and sheath material, and poison exponent is less than 1.5, and oxygen index is greater than 40%.
Described shielding is by the zinc-plated soft copper silk of filament diameter 0.15～0.25mm braid shielded, count 80～85%.
Described inner covering is the wrapped Halogen polyester belt of two plies, Duplication 15～20%.
The advantage of technical scheme provided by the utility model is: conductor has adopted less twisting pitch, makes cable have higher flexibility, cheap laying installation; Insulation has adopted Polyetherimide and the floride-free non-halogen flame-proof cross-linking polyolefin double-layer coextrusion cross-linking radiation of electric property excellence, has improved insulation resistance and the withstand voltage properties of cable; Metallic shield count is high, has improved shield effectiveness and the overload capacity of cable; Sheath adopts floride-free non-halogen flame-proof cross-linking polyolefin to extrude cross-linking radiation, has the performances such as resistance to mineral oil and fuel oil resistance, high-low temperature resistant, acid and alkali-resistance, environmental protection.Electricapparatus performance and the special property of cable are significantly improved, and can meet more broadly high ferro and the use of city gage locomotive vehicle under adverse circumstances, have promoted the Environmental Safety of cable for rolling stock.
