The underlying technology in the BOLD® design is as impressive as its appearance.
Unique inter-phase insulator assembly
Single arched crossarm to hold both circuits
Optimization of individual conductors
Compaction of entire three-phase circuit arrangement into a delta
Millions of simulations and tests have supported early assumptions from AEP’s engineering team about BOLD®’s unique performance characteristics.
Spacer-damper mechanical testing
Single-phase corona cage testing
Three-phase power frequency testing (wet and dry corona & audible noise)
Lightning performance
Switching performance
Lattice structure testing facility
Single-phase insulator and hardware assembly power frequency testing
Spacer-damper mechanical testing
Full-scale structure testing
Significant increases in power delivery capability while avoiding complexities and costs of series compensation
Maximum right-of-way utilization and low-impedance bundled conductors, lower line losses
Simple, elegant, low-profile design that reduces structure heights along with electromagnetic field levels
When we say efficiency we mean a lot of different things, from limiting energy losses to reusing right-of-way by replacing old transmission lines with more capable BOLD® lines instead of siting additional lines.
