Optical fiber composite overhead phase (OPPC) Product Description fiber composite overhead phase OPPC is a special composite power cable, the traditional overhead line structures with one or more galvanized wire (or aluminum clad steel wire) replaced stainless steel fiber unit, it has a dual function for power transmission and communication. OPPC cable features 1, OPPC cable is designed for any of the new low-voltage transmission lines. 2, OPPC OPGW cable and has a similar structure but OPPC phase function due to long-term carrying power transmission, in consideration of the long-running temperature on the optical fiber and optical fiber transmission performance life. 3, mechanical and electrical properties should OPPC consistent with the adjacent wires, such as DC resistance or impedance similar to adjacent wires to ensure that remote voltage three phase change to keep. 4, OPPC installed in high-pressure systems, fittings and accessories (such as strain clamp, suspension clamp and terminal connector box) need to install the insulation, insulated clamps available corresponding strain string or wire insulation hanging string, opto-isolators / separation and connection requires special techniques, the construction requirements are relatively high. Advantages OPPC cable 1, OPPC fiber installed in the phase line, transmission line design optimization, energy saving effect is remarkable 2, no land line lightning triggered off shares, a serious accident off the fiber; cable run safer 3 , high economy 4, not because of the role of field experience galvanic corrosion caused by cable or cables caused ruined, broken fiber and other accidents 5, 6 high-security system, did not give the original line brings additional extra line load 7 hidden, natural anti-theft: the OPPC with both high voltage connector box, has the absolute advantage OPPC cable theft application OPPC cable voltage rating is mainly used in the 110KV line below, such as the distribution network of suburban and rural power grids. Power lines affected by factors, safety, and many more applications on the new line. (1) with a three-phase power system OPPC replace one phase, the formation of a combination of the two wires and a transmission line formed OPPC; mechanical properties, electrical properties and match the two adjacent conductors (2) in the low-voltage grid especially below 35KV distribution lines, and some may not be used to set up the ground. (3) suitable for erection of OPGW and ADSS cable transmission line
