OPPC cable is an alternative aerial self-supporting solution when OPGW or ADSS cable cannot be
used.The cable is used in power transmission lines, due to its excellent performance in low and
medium-voltage electrical networks.This article will provide some knowledge of OPPC cable.
What is OPPC Cable?
An optical phase Conductor (OPPC) cable is a fiber optic cable with dual functions of power
transmission line and communication. OPPC Cable is designed for aerial self-supporting
applications at short, medium, and long-span distances. The basic construction of OPPC is similar
to conventional OPGW, only it is designed to simulate the mechanical and electrical characteristics
of the phase wire it replaces. Unlike OPGW, where the cable is not carrying continuous current,
OPPC is energized along high-voltage power lines. Therefore it requires specially adapted splice

boxes and insulators to accommodate the live line conditions.
The OPPC cable stainless steel tube structure is surrounded by single or double layers of
aluminum clad steel wires(ACS) or mixes ACS wires and aluminum alloy wires aluminum
wires/aluminum alloy wires optical fibers.
Features and Benefits
 Replace one or more of the traditional transmission wires with a stainless steel tube and
strand the tube with AS/steel wires and AL/AA wires.
 Use OPPC cable to replace one phase in the three-phase power system to form a transmission
line composed of two wires and one OPPC.
 OPPC cable can meet durative high-temperature resistant, which was verified by temperature
cycling test.
 There is no serious accident of strand breakage or fiber breakage caused by lightning on the
ground wire, the OPPC cable operation is safer.
 OPPC cable is installed in the phase line to optimize the design of the power transmission line,
and the effect of saving energy is significant.
 OPPC cable provides the optical path of the cable and is resistant to traction.
 OPPC cable provides a high transmission capacity, high communication quality, and high
reliability.

 Suitable for any type of fiber optic cable, single-mode or multi-mode.
Applications
OPPC cable is used in voltage levels below 110kV, suburban power distribution networks, building
distribution automation stations, and rural power grids.
Conclusion
OPPC is typically used in overhead power lines without ground wires, where OPGW or ADSS
cables cannot be installed. OPPC cable provides good safety performance, long service life, and is
not easily subjected to destructive shootings. Sun Telecom provides all OPPC cable products and
solutions to the global market.
