Faa'iidooyinka dahaadhiyeyaasha galaaska:

Sababtoo ah xoogga farsamada sare ee dusha sare ee muraayadda muraayadda, dusha sare uma nugul dillaaco.Awoodda korantada ee muraayadda guud ahaan isma beddesho inta lagu jiro hawlgalka oo dhan, iyo habsocodka gabowga ayaa aad uga gaabiya kan suufka.Sidaa darteed, insulators galaas ayaa inta badan la xoqay ay sabab u tahay is-waxyeelo, taas oo dhacda sanadka ugu horeeya ee hawlgalka, laakiin cilladaha insulators dhoobada yihiin oo kaliya in ay shaqeeyaan dhowr sano oo kaliya ka dib ayaa bilaabay in la ogaado.

Isticmaalka dahaadhiyeyaasha dhalooyinka ayaa baabi'in kara tijaabada ka hortagga caadiga ah ee dahaadhiyeyaasha inta lagu jiro hawlgalka.Tani waa sababta oo ah nooc kasta oo waxyeello ah oo soo gaadha muraayadda kuleylka leh waxay sababi doontaa dhaawaca daaha, taas oo u sahlan hawlwadeenada si ay u helaan marka ay ilaalinayaan khadka.Marka daahiyaha uu dhaawacmo, jajabyada dhalada ah ee u dhow daboolka birta iyo cagaha birta ayaa ku dheggan, iyo xoogga farsamada ee qaybta hartay ee daahiyaha ayaa ku filan si looga hortago in suuliyuhu jabo.Heerarka is-jebinta ee dahaarka dhalooyinka ayaa ah mid ka mid ah tilmaamayaasha muhiimka ah ee lagu cabbiro tayada badeecada, sidoo kale waa saldhigga tayada ee qiimaynta tartanka qandaraaska mashruuca gudbinta ee hadda jira.
