The existing knowledge about strand breakage of OPGW caused by lightning strike still does not clearly define strand breaking caused by lightning arc, calculation of lightning charge energy, criterion for testing and optimizations for engineering design. The results of analysis include: the high temperature of lightning arc working as the main cause of breaking strand; calculation formula of charge-transfer; requirements for modifying the criterion for lightning test that is performed in accordance of available standard; and optimizing measures for engineering design.
