Meet development need, general cable can not be used the long period, easily cause it is damaged wait more serious situation, to using
Person brings loss and potential safety hazard.
Utility model content
In order to solve the problem of prior art is present, the utility model provides a kind of anti-flaming thermal-insulation power line, its intensity
High, anti-flaming thermal-insulation performance is strong, service life length, safety.
The technical solution adopted in the utility model is as follows：
A kind of anti-flaming thermal-insulation power line, including four cross sections constitute the cable core of square structure, and square structure center is empty
Remaining region is provided with supporting-core, and the supporting-core contacts with four cable cores, be provided with each cable core outside conductor, the cable core according to
It is secondary to be provided with the first flame retardant coating, screen layer, armor, flame retardant insulation, the second flame retardant coating and wear-resistance protective sleeve layer, first fire resisting
Layer, screen layer, armor, flame retardant insulation, the second flame retardant coating and wear-resistance protective sleeve layer are coaxial clad structure, each cable core and resistance to
Gap portion between fire bed is provided with packed layer；The wear-resistance protective sleeve layer is externally provided with multiple projections.
Further, provided with multiple stable blocks in the packed layer.
Further, provided with many guide cores in the flame-retardant layer.
Further, the conductor is formed by tinned copper wire is stranded in the same direction, brass wire diameter 0.15mm~0.20mm.
Further, first flame retardant coating and second is ceramic fireproof composite band.
Further, the screen layer is tincopper fuse wire braided armor.
Further, the armor is that stainless steel wire braiding is formed, and is square grid shape structure.
Further, the flame retardant insulation is the elastic body insulated layer of low-smoke non-halogen flame-retardant.
Further, the material of the packed layer is fire-resistant isinglass belt.
