II- Stranded stainless steel tube OPGW optical cable
Stranded OPGW replaces 1 or more aluminum clad steel wires on the noncentral layer of traditional ground wire with stainless steel tube optical unit and strands into overhead cable. It realizes optical fiber communications. Compared with center-based stainless steel tube OPGW, it's especially featured by larger cable diameter and more optical fibers.
Structural features and application
Larger cable diameter, more optical fibers
High tensile strength and short-circuit current capacity. Meet the optimum balance between mechanical and electrical performance.
Allow 1 or more optical fibers
Optimum stranding design. Obtain secondary optical fiber excess length
Two or three layers of stranded wire, single wire
Possible combination of aluminum clad steel wire and/or aluminum alloy wire and aluminum wire

IV- Aluminum clad PBT OPGW optical cable
Aluminum clad loose tube OPGW optical cable core adopts stranded single or more PBT tube optical units, clad with a layer of continuous compressed uniform aluminum tube as metal protection tube which is stranded with another or more layers of aluminum clad steel or aluminum alloy line to form electric optical cable. Aluminum clad loose tube OPGW solves the problem of electrochemical corrosion between different metals. It has high application value.
Structural features and application
Seamless aluminum tube is uniform, compatible with aluminum clad steel wire for ground wire, dispelling the concern about electrochemical corrosion.
Due to uniform material and structure, ground wire has high fatigue resistance.
Optical fiber in aluminum tube OPGW is located in PBT loose tube. After stranding, the cable core will be clad with a layer of thermal insulation material which is excellent in thermal insulation and well protects optical fiber. Therefore, short-circuit current has little influence on transmission performance of optical fibers.

V- Optical Phase Conductor (OPPC)
Optical Phase Conductor (OPPC) is a new type of electric optical cable which compounds optical fiber units in phase conductor. It's capable of both phase conductor and communication. Primarily, it's applied to electric transmission line with no ground wire and a voltage class of 110kV and below in suburban power distribution network and rural power network, etc.
Structural features and application
Performance matching: mechanical and electrical properties match with neighboring two-phase conductor
Continuous heat resistance: temperature cycle and current injecting test verifies that it satisfies continuous constant temperature.
It applies to electric transmission lines of medium and high voltage classes without ground wire.
It is applied to electric transmission lines for which OPGW or ADSS is not practical.

Total Applications:
.OPGW fiber cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are: high voltage over 110kv, with a longer span (usually over 250M);
.easy to maintain, easy for line span, its mechanical property can meet a big line span;
.outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation;
.to construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high voltage line over 110kv;
.For OPGW performance index, the more short circuit current, the more need a good conductor to be metal armor, and reduce tension strength, while, if the tension strength is certain, to increase short circuit current capacity, the only way is to enlarge metal section area, resulting in an increased cable Dia and weight, so that security is a question for line pole strength.
