Electrical reticulation apparatus (1) replaces the traditional cross-arm and insulator(s) construction for overhead power lines. The apparatus (1) is a unitary casting or a composite structure and is insulating throughout. It includes arms (2 and 3) which are adapted to be orientated substantially horizontally when in use and an arm (4) which is adapted to be orientated substantially vertically when in use. A mounting means (11) is provided for mounting the apparatus (11) to a pole, tower or the like. The ends of the arms (2, 3 and 4) which are remote from the mounting means (11) are adapted for the retention of overhead conductors.
