Description
Technical field
The utility model is related to electric wire fields, and in particular to a kind of reinforced fireproof cable.
Background technology
With the development of science and technology, the use scope and occasion of cable are more and more, people also get over the performance requirement of cable
Come it is higher, in some special occasions, it is to be ensured that cable can bear larger drag force and destructive power, in the event of fire, really
The power supply safety for protecting critical facility is most important,
Invention content
The utility model provides a kind of reinforced fireproof cable, it can tension anti-folding fire prevention, prevent external severe ring
Border damages cable, ensures equipment normal operation, and service life is long.
To achieve the above object, the utility model uses following technical scheme：
A kind of reinforced fireproof cable, it includes cable inner core, insulating layer is coated in cable inner core, outside insulating layer
Average mark is furnished with three strands of reinforcing ribs, and filled layer is externally provided in reinforcing rib, and fire resisting wrapping layer is externally provided in filled layer, wrapped in fire resisting
Layer is externally provided with flexible steel band armor, and isolation fireprotection layer is externally provided in armor, is externally provided in isolation fireprotection layer and does not prolong combustion sheath,
It is externally provided with fire resistant coating not prolonging combustion sheath.
Preferably, the inner core is several ultra-fine brass wires.
Preferably, the insulating layer material is mica tape.
Preferably, the reinforcing rib is semicircle PA66 nylon strips.
Preferably, the filling layer material is asbestos cord.
Preferably, the wrapped layer material of the fire resisting is glass fiber tape.
Preferably, isolation fire prevention layer material is Ceramic silicon rubber.
Preferably, the combustion sheath that do not prolong is irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin.
