The central stainless steel pipe is twisted with 1 to 2 layers of single wire，which can be all aluminum clad steel wire or a mixture of aluminum clad steel wire and aluminum alloy wire.
a、Small cable diameter, light weight，and small short-circuit current capacity；
b、The optical unit forms a suitable primary fiber excess length；
c、Slightly poor performance in terms of tensile resistance，torsion resistance, and lateral pressure resistance；
d、Suitable for general renovation of old lines，optical fibers have good strain characteristics under high tension.
Fiber Count: 12-144 Core
Standard: IEEE 1138、IEC 60794-4、 IEC 60793、TIA/EIA 598 A
Fiber Type: G652D；G655C；G657A1；G657A2；50/125；62.5/125；OM3-150；OM3-300；OM4 As Options
1、OPGW optical cables are mainly used on 110KV、220KV、and 550KV voltage level lines，and are generally applied on newly built lines；
2、For lines with high voltage exceeding 110kV，the span is relatively large (usually above 250M)；
3、Easy to maintain，easy to solve line crossing problems，and its mechanical characteristics can meet the requirements of large line crossings；
4、The outer layer of OPGW is metal armor，which has no impact on high-voltage corrosion and degradation；
5、OPGW must be powered off during construction，resulting in significant losses during power outages. Therefore，OPGW should be used in the construction of high-voltage lines above 110kV.
