Pvdf layer, the outer surface of described polyethylene layer, Loose tube and fire-retardant inner sheath are equipped with horizontal non-slip texture.
In foregoing nonmetallic leading in cable, glass fiber tape is additionally provided with the inside of described fire-retardant inner sheath.
In foregoing nonmetallic leading in cable, the groove that spiral is set, groove are provided with the inside of described polyethylene outer sheath
It is interior to be provided with tear rope；The spiral angle of the groove is 60-70 degree.
In foregoing nonmetallic leading in cable, the gap between the adjacent cable core is filled with cable cream.
Compared with prior art, the utility model replaces the center of traditional metal material to strengthen by Fiber glass rod
Part, while proof strength, the weight of optical cable is greatly reduced, be easy to the construction operation of workmen at the scene；Pass through
Fire-retardant inner sheath and fire-retardant oversheath are set outside cable core, by dual fire-retardant, can effectively improve the flame retardant effect of optical cable,
And ceramic fibre strip is set between fire-retardant inner sheath and fire-retardant oversheath, insulation can be played a part of, improve optical cable
Insulating capacity, potential safety hazard of the introduction-type optical cable in thunderstorm weather is reduced, improve the safe to use and reliability of optical cable.Meanwhile
By setting horizontal non-slip texture respectively in the outer surface of polyethylene layer, Loose tube and fire-retardant inner sheath, can ensure mutually
Between bonding strength, make its difficult for drop-off, the safety and stability performance for improving the service life of optical cable and using, in summary,
The characteristics of the utility model has convenient construction and reduces potential safety hazard.
