A tried and tested solution that can be used to replace existing overhead conductors with new, more efficient ones is the subject of a Tratos technical paper that has been accepted by the Institute of Engineering and Technology’s (IET) digital library.
The reference article entitled Overhead conductors – High Voltage was written by Peter Waterworth, Tratos’ Technical and Development Director and Fellow of the Institute of Engineering and Technology. Commissioned by the IET in 2016, it was made available for download from the organisation’s website in April.
The reference article looks at the rapid growing demand for electrical energy which has meant a search for technical innovations to increase power transmission and improve efficiency within tightly constrained budgets.
With few solutions to this complex problem Tratos explored many options including constructing completely new lines along existing routes or replacing existing conductors with new more efficient ones.
The attraction of simply replacing only the conductors in an existing line led Tratos to draw upon more than 40 years of experience and investment in R&D to develop a completely new, more efficient, hybrid load carrying conductor for overhead lines.
Tratos’ OHC-HV (overhead conductor – high voltage), represents the state-of-the-art in overhead line designs. Based on composite carbon fibre core, acting as a support element and thermal resistant aluminium alloy as a conductor, the tailor-made design of the product meets or exceeds the performance of conductors currently available.
Mr Waterworth has more than 50 years’ extensive knowledge and experience of the cable industry worldwide including standards and regulations. Previously he was a member of several National and International Standards Bodies, including BSI, CLC and IEC.

The conductor operated successfully without problems for several years before it was carefully removed, examined and re-evaluated by TERNA.
Ufumbuzi wa majaribio na majaribio ambayo yanaweza kutumika kuchukua nafasi ya conductors ya juu ya sasa na mpya, zaidi ya ufanisi ni mada ya karatasi ya kiufundi ya Tratos ambayo imekubaliwa na Taasisi ya Uhandisi na Teknolojia (IET) maktaba ya digital. Makala ya kumbukumbu yenye kichwa Overhead conductors <unk> High Voltage iliandikwa na Peter Waterworth, Tratos <unk> Mkurugenzi wa Ufundi na Maendeleo na Mwanachama wa Taasisi ya Uhandisi na Teknolojia. Imetengenezwa na IETF mnamo 2016, ilitolewa kwa kupakuliwa kutoka kwa wavuti ya shirika mnamo Aprili. Makala ya kumbukumbu inaangalia mahitaji ya kuongezeka kwa haraka kwa nishati ya umeme ambayo imesababisha utafutaji wa ubunifu wa kiufundi ili kuongeza usafirishaji wa nguvu na kuboresha ufanisi ndani ya bajeti zilizopunguzwa sana. Kwa sababu ya matatizo hayo, Tratos aliamua kujenga mistari mipya au kubadilisha mifereji iliyopo kwa mifereji mpya. Kuvutia kwa kubadilisha tu conductors katika mstari uliopo ilisababisha Tratos kutegemea zaidi ya miaka 40 ya uzoefu na uwekezaji katika R&D ili kuendeleza mstari mpya kabisa, ufanisi zaidi, mstari wa kubeba mzigo wa umeme. Tratos <unk> OHC-HV (overhead conductor <unk> high voltage), inawakilisha hali ya sanaa katika miundo ya mstari wa juu. Kwa kuzingatia msingi wa nyuzi za kaboni, inayofanya kazi kama kipengele cha msaada na alloy ya alumini ya joto kama kondakta, muundo wa bidhaa unaofanywa kwa ajili ya mahitaji ya wateja unakidhi au unazidi utendaji wa kondakta zinazopatikana sasa. Waterworth ana zaidi ya miaka 50 ya maarifa na uzoefu wa kina wa sekta ya cable duniani kote ikiwa ni pamoja na viwango na kanuni. Awali alikuwa mwanachama wa mashirika kadhaa ya kitaifa na kimataifa ya viwango, ikiwa ni pamoja na BSI, CLC na IEC.
