I am a qualified technician, N6 Light Current; have worked in the gold mining industry, with instrumentation & controls; and telecommunication. I have also done project work, as a sub-contractor to Telkom SA Ltd. doing fault-finding, & installation on their copper network. I have also done pipe entry civil work & small manhole construction for FTTH ( fibre to the home). I also install wireless alarm systems for buildings, which use GSM ( cellular signal) for communication; as well as supply & installation of security gates in buildings. Lastly, I supply & install energy saving LED lights to homes using a battery supply ( 12V dc) ; and generators with automated tranfer when main power fails during loadshedding. Many thanks .
