Protection of a cable, its termination and other apparatus from lightning strikes on an overhead line is provided by housing a surge arrestor and a cable termination, which are connected in parallel in a common housing, but as separate components not sharing the same axial line. With this configuration, minimal lead length is provided without sacrificing serviceability.
