Potentialudligning til 8 mm PE-bolte sikrer en effektiv jordforbindelse i PE-rørsystemer. Udligningen består af et bøjleformet klemmebeslag, der fastgøres til PE-røret med en 8 mm bolt. Klemmen har et kobber-/zinkbaseret galvanisk element, der sikrer en langvarig og pålidelig forbindelse til jorden. Ved at tilslutte udligningsklemmen til jordforbindelsen i bygningens el-installation, vil eventuelle overspændinger og strømme lede direkte til jorden. Dette modvirker potentiel skade på rørsystemet og øger sikkerheden for brugerne. Denne type potentialudligning er specielt velegnet til installation i PE-rørsystemer i industrielle og kommercielle miljøer, og kan nemt monteres på eksisterende rør med en diameter på op til 160 mm.
Formålet med dette projekt var at undersøge og evaluere den mest effektive metode til at udføre potentialudligning til 8 mm PE-bolte. Vi har undersøgt de forskellige metoder og fundet frem til, at den mest optimale løsning er at anvende en kobbermanchet.
Vi har konkluderet, at kobber er et ideelt materiale til formålet, da det er en fremragende elektrisk leder og har gode korrosionsbestandige egenskaber. Kobbermanchetten kan nemt installeres på PE-boltene ved hjælp af en kobbersvejseproces, og på denne måde kan en effektiv potentialudligning sikres.
Ved at anvende denne metode kan vi sikre en jævn fordeling af elektrisk potentiale mellem bolte og deres omgivelser, og dermed mindske risikoen for farlige overspændinger og korrosionsskader. Dette kan i sidste ende bidrage til at forlænge levetiden af konstruktioner og udstyr, og samtidig øge sikkerheden og pålideligheden af de anvendte systemer.
Alt i alt har vores undersøgelse vist, at kobbermanchetten er den mest optimale løsning til at udføre potentialudligning til 8 mm PE-bolte, og at denne metode kan føre til en mere pålidelig og effektiv drift af forskelligt udstyr og konstruktioner.
