<p>There is provided a cable television network (10) comprising a first amplifier (12) and a plurality of successive amplifiers (14, 14', 14") all connected in series electrically, with the first amplifier (12) connected to a power source (16) and power for each amplifier routed through the preceding amplifier, wherein at least some of the plurality of successive amplifiers (14, 14', 14") further comprise a power delay device (34, 34', 34") in the form of a relay such that the successive amplifiers are connected to power at different times to reduce current load on each amplifier. Each relay (34, 34', 34") receives electrical power from the preceding amplifier and introduces a power delay of between 100 and 1500ms and more preferably 220- 1000ms.</p> |
