Abstract
The invention discloses a medium soft cable with a natural rubber insulating layer and a rubber-plastic jacket. The medium soft cable comprises the rubber-plastic jacket, a filling layer, a conductor and an insulating layer, wherein the outer layer of the filling layer is wrapped with the rubber-plastic jacket; the outer layer of the insulating layer is wrapped with the filling layer; the conductor is arranged inside the insulating layer; a flame-retardant layer is arranged between the insulating layer and the conductor; the conductor is a copper conductor with relatively high fire resistance; the refractory layer is formed by wrapping multiple layers of mica tapes; the rubber-plastic jacket is made of a soft material. The medium soft cable is high in fire resistance, resistant to high temperature, low in cost and high in safety.
Description
Technical field
The present invention relates to a kind of natural rubber insulation and rubber and plastic overlaps medium-sized flexible cable.
Background technology
Natural rubber insulation and rubber and plastic overlap medium-sized flexible cable and are 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
