Fireproof controlling cable

Abstract

The invention discloses a fireproof controlling cable. The fireproof controlling cable comprises conductors, a pair twisting unit, a wrapping tape layer and an outer sheath layer. The fireproof controlling cable is characterized in that the pair twisting unit is formed by twisting a pair of insulated cable cores, the insulated cable cores are formed by arranging ceramic silicone rubber insulation layers outside the conductors in an extruding and wrapping mode. Glass fiber wrapping tape layers wrap the pair twisting unit in a winding mode to form a main cable core. After being combined, five insulated cable cores wrap a second wrapping tape layer in a winding mode. A steel tape armoring layer is arranged outside the second wrapping tape layer, and a ceramic silicone rubber sheath is arranged outside the steel tape armoring layer. A pulling-preventing steel wire rope is arranged in the center of the cable. A copper conductor drainage wire is arranged between the second wrapping tape layer and the armoring layer. The fireproof controlling cable is high in flame retardant property and excellent in fire resistance, can not be combusted easily and can work normally in the hostile environment of high temperature, low temperature, an acid, a base, oil, water, corrosive gas and the like.

Description

technical field [0001] The invention belongs to the field of electric wires and cables, and relates to a fire-resistant control cable. Background technique [0002] At present, the ordinary power cables sold on the market, because the materials used in these cables do not have high flame-retardant properties, have led to frequent occurrence of fire accidents, resulting in painful people's lives and heavy property losses. A deep understanding of how to ensure unimpeded power and communication within a certain period of time in the event of a fire, to maximize the precious rescue time to reduce casualties and loss of life and property, this is a topic that people have been paying attention to . At present, new fire-resistant cables at home and abroad are actively being researched and developed. After several years of research in China, there is still no ideal sample. At the same time, the traditional fire-resistant cable is only a layer of mica tape wrapped around the conduct...

[0002] At present, the ordinary power cables sold on the market, because the materials used in these cables do not have high flame-retardant properties, have led to frequent occurrence of fire accidents, resulting in painful people's lives and heavy property losses. A deep understanding of how to ensure unimpeded power and communication within a certain period of time in the event of a fire, to maximize the precious rescue time to reduce casualties and loss of life and property, this is a topic that people have been paying attention to

At present, new fire-resistant cables at home and abroad are actively being researched and developed. After several years of research in China, there is still no ideal sample. At the same time, the traditional fire-resistant cable is only a layer of mica tape wrapped around the conductor, and its fire-resistant performance is very poor. Stable and unable to meet the needs of social development
