Conclusion • Partnerships/engagement with utilities enables access to information, infrastructure and funding for research • Combine pro-active and reactive approach where data allows • Variety of anti collision devices already designed,tested and approved in SA – information is feely available • Guidelines for transmission infrastructure, distribution infrastructure (structure design) – information is freely available • Please feel free to approach us for assistance/information
Feel good stories:
