Structure Design
Applications:
OPPC is mainly used in transmission lines of voltage level below 10KV, such as suburban distribution network, rural power grid and etc. Due to power failure, safety and other factors, it’s used mostly in the newly built power lines.
1. Use OPPC to replace one out of the power system’s three phases to form a transmission line composed of two conductors and one OPPC. The mechanical characteristics and the electrical characteristics match with the two adjacent conductors;
2. Mainly used in the medium and low voltage level power grid, especially the distribution lines below 35K. Some can be used without the ground wire;
3. Applicable to the transmission lines also erected with OPGW and ADSS.
Main Features:
1. The design of OPPC is applicable to any newly built medium and low voltage level transmission lines.
2. OPPC’s structure is similar to the OPGW’s, but considering OPPC has the function of phase line and transmits power in the long-term, the influence of the long-term operating temperature on the fiber transmission performance and fiber lifetime should be considered.
3. In order to ensure that the distal voltage change remains three-phase balanced, OPPC’s mechanical and electrical performance should be consistent with the adjacent conductors, like the DC resistance or impedance is similar to its adjacent conductors.
The installed fittings and accessories (such as tension fittings, suspension fittings and joint boxes) shall be insulated if OPPC is installed in a high-voltage system. The corresponding insulated tension string or insulated suspension string can be used for the clamps, while the cable insulation/separation and connection require special techniques, with relatively high construction requirements.
Applicable Voltage Range
Power lines with voltage level of 110KV and below.
