Abstract
The utility model discloses a flame-retardant cable, comprising at least two groups of cable cores. The cable is characterized in that the cable core is formed by wrapping an outer wrapping tape layer. Periphery of the outer wrapping tape layer is wrapped with an outer insulating layer. The outer insulating layer is wrapped with a shielding layer. Periphery of the shielding layer is wrapped with a flame-retardant layer. Periphery of the flame-retardant layer is wrapped with a sheath layer. The cable core is formed by twisting a group or a plurality of groups of conductors. The conductors are wrapped with inner wrapping tape layers. Periphery of the inner wrapping tape layers is wrapped with inner insulating layers. The cable is advantaged by flame-retardance, high temperature resistance, and simple structure, and saves cost. The cable is very convenient to use, performance of the cable is improved, and transmission performance and accuracy of various control signals are ensured.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of flame retardant cable.
Background technology
Along with rapid economy development, cable there are various specific demands.Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.For the construction of engineering constructions such as subway, tunnel, the cable-flame retardant performance demands is more and more higher.Cable-flame retardant poor performance of the prior art, especially cable in use any problem can not occur, and the single construction of cable can't satisfy diversified requirement.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of flame retardant cable.
The technical solution adopted in the utility model is:
A kind of flame retardant cable, the cable core that comprises at least two groups, it is characterized in that: described cable core is coated by outer belting layer and forms, described outer belting layer periphery is coated with external insulation layer, and described external insulation layer is coated with screen, and described screen periphery is coated with flame-retardant layer, described flame-retardant layer periphery is coated with restrictive coating, described cable core forms by one or more groups conductor is stranded, and described conductor is coated by interior belting layer and forms, and described interior belting layer periphery is coated with inner insulating layer.
Described external insulation layer is Flame-Retardant and Oil-Resistant wearproof structural tier or flame-proof silicon rubber structure sheaf.
Described inner insulating layer is low-smoke non-halogen flame-retardant oil resistant structure sheaf or flame-proof silicon rubber structure sheaf.
Belting layer and outer belting layer are the alkali-free glass wool band in described.
The utility model has the advantages that: flame-resistant high-temperature-resistant, simple in structure, saved cost, use very conveniently, improved the performance of cable, ensured the accuracy of electric energy transmitting and various control signals.
