CN201886183U - Self-supporting type comprehensive optical cable - Google Patents

Abstract

The utility model relates to a self-supporting type comprehensive optical cable, in particular to a self-supporting type comprehensive optical cable which can be used indoors and outdoors. The self-supporting type comprehensive optical cable consists of a cable core, a copper twisted pair and an aramid fiber reinforced layer. When the self-supporting type comprehensive optical cable works, the self-supporting type comprehensive optical cable can be directly used indoors and outdoors without conversion.

Description

The self-bearing type complex cable

Technical field

The utility model relates to the general self-bearing type complex cable of a kind of self-bearing type complex cable, particularly indoor and outdoor.

Background technology

The outer cable configuration of present domestic conventional chamber is big, external diameter thick, pliability is poor again, is not suitable for house wiring, and traditional optoelectrical cable also is like this; The tradition inside cable is because tensile strength is less, the relative outdoor optical cable of temperature performance is also poor, thus can't be at outdoor laid, and separately wiring of optical cable.

The utility model content

In order to solve above-mentioned drawback; the utility model provides a kind of indoor and outdoor general self-bearing type complex cable; comprise galvanized strand wires; PVC or fire-retardant PE sheath; the aramid fiber enhancement Layer; single mode or multimode silica fibre; factice for filling, the PBT sleeve pipe, copper cash is right; wherein said self-bearing type complex cable; the optical cable tangent plane holds 8 fonts, and galvanized strand wires is coated formation top 0 by PVC or fire-retardant PE sheath, and the PBT sleeve pipe of filling multimode silica fibre and ointment is coated formation bottom 0 by PVC or fire-retardant PE sheath; middle by strip PVC or fire-retardant PE connection, and 4 pairs of copper stranded conductor symmetric offset spread are in the PVC or fire-retardant PE sheath of PBT outside of sleeve.

Wherein said self-bearing type complex cable, its feature also is: the 4 pairs of copper stranded conductors and PBT outside of sleeve and PVC or the fire-retardant PE sheath outside are equidistant.

Embodiment

New indoor outdoor use self-bearing type complex cable is applicable to short distance Metropolitan Area Network (MAN), introducing not in the know, Fiber to the home etc., and optical cable can be directly indoor by outdoor introducing, need not switching.

Considered emphatically that in structured design process this optical cable must satisfy outdoor and indoor environmental requirement and construction requirement, as reinforcing element, and make the self-bearing type structure with aramid fiber, to adapt to outdoor no messenger wire construction, simultaneously for house wiring, messenger wire is adopted the small dimension steel strand wires, guarantee the pliability of optical cable, and cable core is made half dry type, be convenient to indoor construction, maintenance, considered different request for utilizations simultaneously, optical cable is introduced copper conductor, satisfies electric access way simultaneously.

As shown in Figure 2, the self-bearing type complex cable that the utility model provides, the optical cable tangent plane holds 8 fonts, galvanized strand wires 1 is coated formation top 0 by PVC or fire-retardant PE sheath, the PBT sleeve pipe 6 of filling multimode silica fibre 4 and ointment 5 is coated formation bottom 0 by PVC or fire-retardant PE sheath, middle connected by strip PVC or fire-retardant PE, and 4 pairs of copper stranded conductor symmetric offset spread are in the PVC or fire-retardant PE sheath 2 of PBT outside of sleeve, the 4 pairs of copper stranded conductors and PBT outside of sleeve and PVC or fire-retardant PE sheath 2 outsides are equidistant.

As shown in Figure 3, the self-bearing type complex cable is finished through the step of optical fiber warehouse-in-optical fiber coloring-secondary coating-sheath installation.

Thus, the outer one self-bearing type complex cable of new indoor newly developed has been taken into account the environment for use of indoor and outdoor, when softness is run business into particular one, done to optical cable, has improved its mechanical property and temperature performance, make the photoelectric comprehensive cable structure simultaneously, satisfy two kinds of different access waies of photoelectricity;

The outdoor self-bearing type complex cable of new indoor newly developed is that messenger wire is made the self-bearing type structure with the small dimension steel strand wires also, satisfies the indoor and outdoor short distance and does not have messenger wire and hang and to set up.

The utility model is not limited to the foregoing description; in design scope of the present utility model; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of the utility model claim.

Claims (2)

1. self-bearing type complex cable; be characterised in that and comprise galvanized strand wires (1); PVC or fire-retardant PE sheath (2); aramid fiber enhancement Layer (3); single mode or multimode silica fibre (4); factice for filling (5); PBT sleeve pipe (6); copper cash to (7) wherein the optical cable tangent plane hold 8 fonts; galvanized strand wires (1) is coated formation top 0 by PVC or fire-retardant PE sheath; the PBT sleeve pipe (6) of filling multimode silica fibre (4) and ointment (5) is coated formation bottom 0 by PVC or fire-retardant PE sheath, and the centre is connected by strip PVC or fire-retardant PE, and 4 pairs of copper stranded conductor symmetric offset spread are in the PVC or fire-retardant PE sheath (2) of PBT outside of sleeve.

2. according to the described self-bearing type complex cable of claim 1, it is characterized in that: the 4 pairs of copper stranded conductors and PBT outside of sleeve and PVC or fire-retardant PE sheath (2) outside are equidistant.
