Custom OPPC Cable Manufacturer in China
Tailored design & fabrication of OPPC Cable for your power transmission & distribution lines
What is an OPPC Cable
In order to meet the requirements of power monitoring or fiber optic network connectios, power utilities would like to have a full utilization of its own electrical towers or poes, especially in some power distribution lines, and to avoid the conflicts in terms of frequency resources, routing coordination, electromagnetic compatibility, etc. By adding fiber optic units in traditional phase condutor through appropriate methods, an OPPC Cable is formed, which is also known as optical phase conductor. so it is clear to see, OPPC cable has double functions of phase conductors and fiber optic telecommunication capabilities.
In last 10 years, PowerTel & its factory have supplied different types of OPPC Cable for power utilities in home & abroad. Meanwhile, based on our 10 years experience, we have capacities to offer you a tailored design & fabrication of this OPPC cable for your power transmission & disbution lines.
OPPC Cable for Your Power Transmission & Distribution Lines

Individual Design of OPGW Cable for Your Project
Over 10 years of manufacturing experience of this OPPC cable, our dedicated engineers are able to provide you a custom design & its fabrication to fit your power transmission & distribution lines.
Complete Product Chain for OPPC Cable
Except this OPPC cable, we are also available for its hardware & fittings, such as splice box and tension & suspension clamps. Due to the unique structure of an OPPC Cable, it need to use pre-formed fittings to protect the fibers during installation. The use of pre-formed fittings has three advantages: firstly, the construction is simple and fast, no need to take heavy compressors, crimping pliers on site. Secondly, pre-formed fittings are in good conductivity and significant energy-saving effects; thirdly, the installation of pre-formed fittings increased the contact surface between the wires on fittings and OPPC cable, which increases in length, evenly distributes the force, reduces the fatigue of the wire, prolongs the life of the wire, and improves the seismic resistance etc.

Main features of this OPPC Cable
1. The design of OPPC cable is suitable for any new power transmission & power distribution line and voltage level lower than 110 kV.
2. The structure of OPPC cable is similar to OPGW cable, but due to its fuction of a phase conductor, OPPC cable need to carry the current all the time. Therefore, the impact of long-term operating temperature on the transmission performance and lifespan of optical fiber need to considered when you design and choose a proper type of OPPC Cable.
3. The mechanical and electrical properties of OPPC cable should be consistent with adjacent phase conductors, such as DC resistance or impedance similar to adjacent phase conductor, to ensure that the remote voltage changes maintain three-phase balance.
4. OPPC cable is installed in a high-voltage system, and its hardware and accessories (such as tension clamps, suspension clamps, and terminal splice box ) need to be insulated. The clamps can be used with corresponding insulated tension wire strings or insulated suspension strings. optic fiber-phase conductor insulation/separation and connection require special technology, which requires relatively high construction requirements.
Advantages of an OPPC Cable
1. The optical fibers housed in an optical unit and stranded with phase conductors,m thus to optimize the design of the whole power transmission or distribution lines, and achieve significant energy savings.
2. there will be no serious accidents such as wire breakage or fiber breakage caused by lightning strikes on the ground wire;
3. There were no accidents such as electric corrosion or cable damage or breakage caused by the effect of field strength on OPGW cable or ADSS Cable.
5. High security performance of an OPPC Cable.
6. No hidden dangers caused by adding extra line loads to the original power transmissin or distribution lines.
Applications of an OPPC Cable
OPPC cables are mainly used on power lines with a voltage level below 110KV, such as suburban power distribution networks and rural power grid network. Affected by factors such as power outages and safety, it is mainly applied to newly built power distribution lines.
(1) Replace one phase conductor with an OPPC Cable on an exsiting power transmission or a distribution line ; Mechanical and electrical characteristics need to be matched
(2) In medium and low voltage power grids, especially for distribution lines below 35KV, some can be used on power lines without grounding wires.
(3) used on some Transmission or distribution lines unsuitable for installing OPGW and ADSS cables.
