Abstract
The utility model discloses a ceramic fire-proof and fire-resistant cable, comprising a plurality of cable cores. Each cable core comprises a conductor and a ceramic silicon rubber fire-proof and fire-resistant layer coating the conductor. An insulating layer is arranged outside the ceramic silicon rubber fire-proof and fire-resistant layer of each cable core. High-temperature resistant filling layers are arranged among the ceramic silicon rubber fire-proof and fire-resistant layers, and outer sleeves are sleeved outside the high-temperature resistant filling layers. The insulating layers are arranged between the conductors of the cable cores and the ceramic silicon rubber fire-proof and fire-resistant layers, so as to improve the insulating property of the cable cores of the cable, and prevent the cable from breakdown caused by a low insulating property. The ceramic fire-proof and fire-resistant cable is applicable to low-voltage, middle-voltage and high-voltage cables.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of potteryization fireproof cable.
Background technology
Chinese patent is announced CN201134299Y and is disclosed a kind of potteryization silicon rubber insulation fire-resistant cable; This fire-resisting cable comprises some cable cores; Each cable core comprises the refractory insulating layer of conductor, coating conductor, is provided with high temperature resistant packed layer and protective layer between these cable cores; The appearance of cable is an external sheath layer, and refractory insulating layer is to be material with pottery silicon rubber.
Yet the refractory insulating layer that the conductor of above-mentioned fire-resisting cable cable core coats only can be applicable to low-voltage cable because of being that material causes cable insulation to reduce with pottery silicon rubber, and causes puncture when being applied to high-tension cable easily.
