Abstract
The utility model relates to a high flame retardance refractory cable which comprises compacted conductors formed by compacting and stranding a plurality of wires, wherein lapped insulating layers and color separation insulating layers are sequentially arranged on the outer sides of the compacted conductors from inside to outside to form cable conductors; a plurality of cable conductors are stranded together; parts between the stranded cable conductors are filled with a filling layer; a first lapped layer, a cladding layer, an isolation layer, an oxygen isolation layer, a second lapped layer and an outer extruded layer are sequentially arranged on the outer side of the stranded cable conductors; an armored layer is arranged in the oxygen isolation layer; the cladding layer is an aluminum sheath; polyolefin is adopted for the outer extruded layer; inorganic minerals are adopted for the lapped insulating layer, the filling layer and the oxygen isolation layer; polyolefin is adopted for the color separation insulating layer and the isolation layer; a high-temperature resistant composite tape is adopted for the first lapped layer; fine steel wires are adopted for the armored layer; a non-woven fabric is adopted for the second lapped layer. The high flame retardance refractory cable has the beneficial effect that the high-temperature resistance, high flame retardance and insulation performance of the cable are fully ensured.
Description
Technical field
The utility model relates to a kind of high flame retardant fire-resisting cable.
Background technology
Cable is in actual life, to need a large amount of a kind of power transmission devices that use, and can carry out the long-distance transmissions of electric power, brings great convenience to people's work, life.Along with expanding economy, building develops to high level, the accelerating development of the increase of various electric installations and power grid construction, and disaster hidden-trouble also increases thereupon, has increased the danger level of breaking out of fire.According to statistics, in many fire incidents, the fire being caused by electric wiring reaches 80%.Fire not only can cause a large amount of economic losses, also can produce a large amount of poisonous and hazardous gas in cable combustion process, causes environmental pollution.
Utility model content
The purpose of this utility model is to provide a kind of high flame retardant fire-resisting cable, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of high flame retardant fire-resisting cable, comprises by some wires and presses the stranded compact conductor forming, and described compact conductor outside forms cable conductor by interior after setting gradually outward wrapping insulation layer, color separation insulating barrier; Described some cable conductors twist together, and between described some twisted cable conductors, packed layer are set and fill; Described twisted cable conductor outside is disposed with outward lapping layer one, coating layer, separator, oxygen barrier layer, lapping layer two and is extruded skin by interior; In described oxygen barrier layer, be provided with armour; Described coating layer is aluminium cover; The described skin that extrudes is for polyolefin.
Optionally, described wire is copper cash, and described copper cash is 2-5 root; Described cable conductor is 4.
Further, described wrapping insulation layer, packed layer and oxygen barrier layer are inorganic mineral.
Further, described color separation insulating barrier and separator are polyolefin.
Further, described lapping layer one is high temperature resistant composite band.
