Abstract
The utility model discloses a meter cable for a nuclear power station, comprising conductors, an inner insulating layer, a halogen-free insulating layer, a polyester belt, a branch shielding layer, a drainage wire, a flame retardation wrapping belt layer, an inner sheath, an armoured layer and an outer sheath, wherein between the polyester belt and the branch shielding layer there is provided the drainage wire, and the inner sheath layer is wrapped with the armoured layer through extrusion. The meter cable for a nuclear power station has the characteristics of being free of halogen, and being low in smoke, and being flame retardant, environment-friendly and healthful, and also has the characteristics of being small in smoke dust and high in light transmittance, being free of halogen, and being lower in corrosivity of the combustion released gas.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of instrument cable for nuclear power station.
Background technology
Along with socioeconomic development, the electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable that especially uses in the nuclear power station field, to the flame-proof environmental protection of cable and low cigarette, Halogen-free requirement high especially.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of instrument cable for nuclear power station with Halogen, low cigarette, flame-proof environmental protection characteristic.
The utility model takes following technical scheme to realize: a kind of instrument cable for nuclear power station, it is comprised of conductor, interior insulation, Halogen insulation, polyester band, sub-shield, drainage thread, fire-retardant belting layer, inner sheath, armour and oversheath, on the described polyester band described drainage thread is installed, described inner sheath is extruded with described armour outward.
The utlity model has in sum following beneficial effect: the utlity model has the characteristic of Halogen, low cigarette, flame-proof environmental protection health, flue dust is less when burning in addition, light transmittance is high, and is not halogen-containing, and burning discharges the lower characteristics of gas attack.
