Abstract
The invention discloses a novel fireproof cable. The novel fireproof cable comprises a sheath, a packing layer, a conductor and an insulation layer, wherein the sheath wraps an outer layer of the packing layer; the packing layer wraps an outer layer of the insulation layer; the conductor is arranged in the insulation layer; a fireproof layer is arranged between the insulation layer and the conductor; the conductor is a copper conductor with higher fireproof performance; the fireproof layer is formed by wrapping a plurality of layers of mica tapes; stone particles are added in the sheath; the insulation layer comprises an asbestos layer and hollow microspheres. The novel fireproof cable is high in fireproof performance, resistant to high temperature, low in cost and high in safety.
Description
Technical field
The present invention relates to a kind of novel flame resistant cable.
Background technology
Novel flame resistant cable is widely used in the place relevant with fire safety and fire-extinguishing and lifesaving such as skyscraper, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises, such as, fire-fighting equipment and promptly to supply line and the control circuit of the emergency services such as leading lights., although the normal power supply that still can maintain a period of time after catching fire, there is price, complex process, problem that difficulty of construction is large in existing mineral insulated cable
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide a kind of novel flame resistant cable, fire resistance is good, high temperature resistance, and cost is low, and fail safe is high.
To achieve these goals, the present invention realizes by the following technical solutions: it comprises sheath (2), packed layer (1), conductor (5) and insulating barrier (3), and described sheath (2) is wrapped in the skin of packed layer (1); Described packed layer (1) is wrapped in the skin of insulating barrier (3); Be provided with conductor (5) in described insulating barrier (3), described sheath is added with stone granulate in (2), and described insulating barrier (3) is made up of asbestos layer and cenosphere.
As preferably, between described insulating barrier (3) and described conductor (5), be provided with flame retardant coating (4).
As preferably, described conductor (5) is cadmium copper alloy.
As preferably, described flame retardant coating (4) is formed by multilayer Mica tape.
As preferably, described flame retardant coating is provided with graphite in (4).
Fire resistance of the present invention is good, high temperature resistance, and cost is low, and fail safe is high.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention;
Embodiment
