In combination with the conductor covers, the suspension string and pole head cover is used to allow : • The operator to reduce the distance between his working area and the parts protected by the cover. • It can also be used to avoid accidental contact between phase-to-phase and phase-to-earth. In all cases, protruding network elements must be removed before the cover is fitted. If the conductor is held by a conductor support stick or sticks, the suspension clamp must also be removed.
