OPPC optical cable is a new choice for power communication
The Ministry of Technology stated that it is difficult to use other special power optical cables for some lines, and when the reliability and safety of ordinary optical cables and carrier communication are difficult to guarantee, the selection of OPPC optical cables can safely and reliably solve the problem of line communication: 10kV, 35kV and a certain Some 66kV and other low-voltage transmission lines themselves have no ground wire;
The safety distance between the line and the ground is not enough, it is impossible to solve the problem of crossing, insufficient tower strength, frequent diversion, etc.; the use of ordinary optical cables has problems of being stolen and maintained; carrier communication is limited by climate and terrain; some transmission lines without communication means must be used .
OPPC can also be used for wire melting. Severe icing of transmission lines may cause downed towers and disconnection accidents. In the face of ice and snow disasters, timely and effective melting of ice-covered lines has become the key to maintaining safe and stable operation of the power grid and ensuring normal power supply. 220kV, 110kV, 35kV and below lines are widely used to melt ice by thermal method. A 10kV voltage is applied to a string of wiring, and the heat generated by the short-circuit large current is used to melt the ice. Therefore, the OPPC optical cable is used to melt the ice using the thermal method, and the power transmission and communication scheduling can be better guaranteed.
OPPC uses the corridor resources and tower resources of a transmission line to build optical cables along power lines. Compared with conventional wires + ordinary optical cables, the material cost can be saved by 10%-20%, and it can also save a construction cost. Therefore, it has relative technical and economic advantages.
