Abstract
The invention discloses a cable with high fireproof performance. The cable comprises a sheath, a filling layer, a conductor and an insulating layer, wherein the sheath wraps the outer layer of the filling layer, the filling layer wraps the outer layer of the insulating layer, the conductor is arranged in the insulating layer, a fireproof layer is arranged between the insulating layer and the conductor, the conductor is a copper conductor with better fire resistance, and the fireproof layer is formed by wrapping of multiple layers of mica tapes. The cable is good in fire resistance, high-temperature-resistant, low in cost and high in safety.
Description
Technical field
The present invention relates to a kind of high fire protecting performance cable.
Background technology
High fire protecting performance 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
