| Abstract | Currently the only method available to GB Electricity Network Licensees for the uprating of 275kV OHL circuits to 400kV circuits is to re-build the towers to a higher specification. Composite Cross Arms will allow GB Electricity Network Licensees to up-rate 275kV to 400kV without the need for building new circuits. This is due to the electrical properties of the cross-arms, and the slightly altered installation configuration compared to standard cross-arms, which results in the conductor being raised higher from the ground. This technology will be valuable to GB Electricity Network Licensees and consumers and stakeholders in helping to provide extra capacity to the Transmission system without the need for the construction of new and taller towers that are more visually intrusive upon the landscape. Research, Development & Demonstration The method proposed involves a 5 stage approach. Stages 1 & 2: Feasibility Study on the uses of composite crossarms on 275kV and 400kV system and prototype manufacture. Stage 3: electrical, mechanical and environmental testing of the crossarm, and ancillary system design. Stage 4: involves Scottish Hydro Electric Transmission only and is described as part of their project NIA_SHET0003. Stage 5: manufacture of 6 crossarms for testing, 4 x 6 monthly performance monitoring reports, and final reports on tension towers, and performance trials at 400kV.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
