Ukusebenza kwezinto zokufaka ukushisa okushisayo kuyisici esibalulekile ekwakhiweni kwesakhiwo kanye nokusebenza kahle kwamandla. Phakathi kwezinto eziningi ezithinta ukusebenza kwe-insulation, i-coefficient yokumelana nokusakazwa komhwamuko (μ) idlala indima ebalulekile. Ukuqonda ukuthi le-coefficient ithinta kanjani izinto zokufakelwa kusiza ekukhetheni izinto ezingcono, ngaleyo ndlela kuthuthukiswe ukusebenza kwesakhiwo.
I-coefficient yokumelana nokusakazwa komhwamuko wamanzi (imvamisa ichazwa ngu-μ) iyinkomba yekhono lempahla lokumelana nokudlula komhwamuko wamanzi. Kuchazwa njengesilinganiso sokumelana nokusakazwa komphunga wamanzi wento esetshenziswayo kuya kulokho okusethenjwayo (imvamisa umoya). Inani eliphakeme lika-μ libonisa ukumelana okukhulu nokusabalalisa umswakama; inani eliphansi lika-μ libonisa ukuthi impahla ivumela umswakama owengeziwe ukuba udlule.
Omunye wemithelela eyinhloko ye-coefficient yokumelana nokusakazwa komphunga wamanzi ezintweni zokufakwa ezishisayo yithonya layo ekulawuleni umswakama ngaphakathi kwezingxenye zesakhiwo. Izinto ezibamba ukushisa ezine-coefficient yokumelana nokusakazwa komhwamuko ophezulu (inani elingu-μ) zivimbele ngempumelelo umswakama ukuthi ungangeni kungqimba olufakwa ngaphakathi, olubalulekile ekugcineni ukusebenza kokushisa. Lapho izinto zokufakelwa ziba manzi, ukumelana kwazo nokushisa kwehla kakhulu, okuholela ekwandeni kokusetshenziswa kwamandla okushisa noma ukupholisa. Ngakho-ke, ukukhetha izinto zokuvikela ezine-coefficient efanelekile yokumelana nokusakazwa komhwamuko (μ value) kubalulekile ukuze kuqinisekiswe ukuthi zigcina ukusebenza kahle esikhathini eside.
Ngaphezu kwalokho, i-coefficient yokumelana nokusakazwa komphunga wamanzi nayo ithinta ubungozi bokufingqa ngaphakathi kwezingxenye zesakhiwo. Ezindaweni ezinomswakama ophezulu noma izifunda ezinomehluko omkhulu wokushisa, umswakama uzoncipha ezindaweni ezipholile. Izinto zokufaka i-insulation ezine-conductivity yamanzi ephansi (i-μ value) zingavumela umswakama ukuthi ungene engxenyeni futhi ujiye ngaphakathi, okuholela ezinkingeni ezingaba khona ezifana nokukhula kwesikhunta, ukulimala kwesakhiwo, nokuncipha kwekhwalithi yomoya wasendlini. Ngokuphambene, izinto ezinomthamo ophezulu wamanzi zinganciphisa lezi zingozi ngokuvimbela ukugeleza komswakama, ngaleyo ndlela zithuthukise ukuqina nempilo yesevisi yemvilophu yokwakha.
Lapho ukhetha izinto zokufakelwa, isimo sohlelo oluthile kanye nezimo zemvelo kufanele kubhekwe. Isibonelo, ezimweni ezibandayo lapho ingozi yokufingqa iphezulu, kunconywa ukusebenzisa izinto zokufakelwa nge-coefficient yokumelana nokusabalalisa umswakama ophezulu wamanzi. Lokhu kusiza ukugcina ungqimba olufakwa ngaphakathi lomile futhi lugcine ukusebenza kwalo kokuvikela. Ngakolunye uhlangothi, ezindaweni ezifudumele nezinomswakama, ukuhwebelana kufanele kushaywe. Nakuba ukuphikiswa komswakama kudingekile, i-coefficient yamanzi ephezulu ngokweqile (i value) ingabangela umswakama ukuthi uhlale ngaphakathi odongeni, okuholela kwezinye izinkinga. Ngakho-ke, ukuqonda isimo sezulu sendawo kanye nezidingo ezithile zesakhiwo kubalulekile lapho kukhethwa izinto zokufakelwa.
Ngaphandle kokulawula umswakama, i-coefficient yokumelana nokusakazwa komhwamuko wamanzi iphinde ibe nomthelela ekusebenzeni kahle kwamandla kwesakhiwo. Ukukhetha izinto zokuvikela ezifanele kanye nokulawula umswakama ngempumelelo kunganciphisa izindleko zamandla, kuthuthukise ukunethezeka, futhi kuthuthukise ikhwalithi yomoya wasendlini. Lokhu kubaluleke kakhulu emisebenzini yokwakha esimeme, lapho ukonga kwamandla kanye nomthelela emvelweni kuyizinto ezicatshangelwayo.
Ngamafuphi, ukumelana nokusakazwa komhwamuko wamanzi kuyisici esibalulekile ekuhloleni ukusebenza kwezinto zokufakwa ezishisayo. Umthelela wawo ekulawuleni umswakama, ingozi yokujiya, kanye nokusebenza kahle kwamandla kukonke kugcizelela ukubaluleka kokukhetha izinto ezibonakalayo ngokucophelela ekwakhiweni kwesakhiwo. Ngokuqonda nokusebenzisa izimiso zokumelana nokusakazwa komhwamuko wamanzi, abaklami bezakhiwo, osonkontileka, nabanikazi bangenza izinqumo ezinolwazi zokwakha izakhiwo ezihlala isikhathi eside, ezisebenza kahle, nezinethezekile. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukudidiyelwa kwamasu okulawula umswakama kuzohlala kuyisici esibalulekile ekuzuzeni izixazululo ezisebenza kahle kakhulu zokuvikela umswakama.
