Abstract
The invention discloses a plastic insulated control cable. The cable comprises a protective sleeve, a filling layer, a conductor and an insulating layer, wherein the outer layer of the filling layer is wrapped with the protective sleeve; the outer layer of the insulating layer is wrapped with the filling layer; the conductor is arranged in the insulating layer; a fire-resistant layer is arranged between the insulating layer and the conductor; the conductor is a copper conductor with the higher fire resistance; the fire-resistant layer is formed by winding multiple layers of mica tapes; the protective sleeve consists of a heat-insulating layer, a cavity layer and a fire-resistant layer. The cable is high in fire resistance, high-temperature-resistant, low in cost and high in safety.
Description
Technical field
The present invention relates to a kind of plastic insulation control cables.
Background technology
A kind of plastic insulation control cables 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 plastic insulation control cables, 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 (2) is made up of thermal insulation layer, cavity layer and resistance to burning zone.
As preferably, between described insulating barrier (3) and described conductor (5), be provided with flame retardant coating (4).
As preferably, described conductor (5) is the good copper conductor of fire resistance.
As preferably, described flame retardant coating (4) is formed by multilayer Mica tape.
