What specific components did Murray focus on improving due to the continuous battle to find materials that could reliably withstand high voltage stresses?

Answer

Insulators

Murray's work on insulators was particularly notable because finding materials that could reliably withstand the stresses of high voltage without degrading was a continuous battle.
