nsanja za mphezi zimatchedwanso nsanja zamphezi kapena nsanja zochotsa mphezi. Atha kugawidwa kukhala ndodo zozungulira zitsulo zamphezi ndi ndodo zachitsulo zozungulira malinga ndi zida zomwe zimagwiritsidwa ntchito. Malinga ndi ntchito zosiyanasiyana, amatha kugawidwa kukhala nsanja za mphezi ndi nsanja zoteteza mphezi. Zozungulira zitsulo zozungulira zimagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika. Zida zomwe zimagwiritsidwa ntchito pazitsulo zopangira mphezi zingaphatikizepo zitsulo zozungulira, zitsulo za ngodya, mapaipi achitsulo, mapaipi achitsulo amodzi, ndi zina zotero, kutalika kwa mamita 10 mpaka 60 mamita. Ndodo za mphezi zimaphatikizapo nsanja za mphezi, nsanja zodzitetezera ku mphezi, nsanja zochotsa mphezi, ndi zina.

Cholinga: Amagwiritsidwa ntchito poteteza mphezi mwachindunji m'malo olumikizirana, ma radar, ma eyapoti, malo osungira mafuta, malo oponya mizinga, PHS ndi malo osiyanasiyana oyambira, komanso kumanga madenga, magetsi, nkhalango, malo osungira mafuta ndi malo ena ofunikira, malo opangira nyengo, ma workshop a fakitale, mphero zamapepala, ndi zina zotero.

Ubwino: Chitoliro chachitsulo chimagwiritsidwa ntchito ngati nsanja yachitsulo, yomwe imakhala ndi mphamvu yamphamvu yamphepo komanso kukana kwamphamvu kwa mphepo. Mizati ya nsanjayi imalumikizidwa ndi mbale zakunja za flange ndi mabawuti, zomwe sizili zophweka kuonongeka ndikuchepetsa mtengo wokonza. Mizati ya nsanjayo imakonzedwa mu makona atatu ofanana, omwe amasunga zipangizo zachitsulo, amakhala ndi malo ang'onoang'ono, amapulumutsa malo, komanso amathandizira kusankha malo. Thupi la nsanjayo ndi lopepuka, losavuta kunyamula ndikuyika, ndipo nthawi yomanga ndi yochepa. Mawonekedwe a nsanja amapangidwa kuti asinthe ndi mayendedwe olemetsa mphepo ndipo amakhala ndi mizere yosalala. Sikophweka kugwa m'masoka a mphepo ndipo kumachepetsa kuvulala kwa anthu ndi nyama. Mapangidwewa akugwirizana ndi ndondomeko ya mapangidwe azitsulo zamtundu wa dziko ndi ndondomeko ya mapangidwe a nsanja kuti atsimikizire chitetezo ndi kudalirika kwa dongosololi.

Mfundo yachitetezo cha mphezi: Chowongolera mphezi ndi chowongolera, chocheperako chachitsulo chamkati. Pambuyo pa kugunda kwa mphezi, mphamvu ya mphezi imayendetsedwa kudziko lapansi kuti ateteze nsanja yotetezedwa ya antenna kapena nyumba kuti iwonongeke kumbali. Nthawi zambiri, mphamvu ya electrostatic field zingwe ndi zosakwana 1/10 ya nsanja Impedans, amene amapewa magetsi nyumba kapena nsanja, kuchotsa zoletsa flashover, ndi kuchepetsa kukula kwa overvoltage anachititsa, potero kuchepetsa kuwonongeka kwa zida zotetezedwa. Mitundu yachitetezo imawerengedwa molingana ndi njira ya mpira wakugudubuza ya GB50057.
