Mulingo wachitetezo cha masinthidwe a mafakitale amalembedwa ndi IEC (International Electrotechnical Association). Ikuyimiridwa ndi IP, ndipo IP imatanthawuza "chitetezo cha ingress. Ndiye, tikamagula masiwichi a mafakitale, ndi mlingo wotani wa IP wa masiwichi a mafakitale?

Sankhani zida zamagetsi molingana ndi fumbi komanso kukana madzi. Mulingo wachitetezo cha IP nthawi zambiri umakhala ndi manambala awiri. Nambala yoyamba imayimira ndondomeko yowonongeka ya fumbi ndi zinthu zakunja (zida, manja a anthu, etc.), ndipo mlingo wapamwamba ndi 6; nambala yachiwiri imayimira ndondomeko yosindikizira yopanda madzi ya zipangizo zamagetsi, mlingo wapamwamba kwambiri. Ndi 8, kuchuluka kwa chiwerengerocho, kumapangitsa kuti chitetezo chikhale chokwera.

Ogwiritsa ntchito akagula masiwichi akumafakitale, nthawi zambiri amasankha masiwichi akumafakitale okhala ndi milingo yoyenera yotetezedwa malinga ndi malo omwe amagwiritsa ntchito. Pakusintha kwa mafakitale, mulingo wa chitetezo cha IP ndi index ya fumbi ndi kukana madzi, ndiye nchiyani chimayambitsa kusiyana kwa index? Izi makamaka zokhudzana ndi chipolopolo zakuthupicha kusintha. Zosintha zamafakitale makamaka zimaphatikizapo aloyi ya aluminiumzipolopolo ndi malata zitsulo mapepala. Mosiyana ndi izi, zotayira za aluminiyamu zimakhala ndi chitetezo chapamwamba.

Zosintha zamafakitale, ngati chitetezo chambiri chikupitilira 30, chimatha kuzolowera malo ovuta a mafakitale, omwe angatsimikizire kulumikizana kotetezeka, kodalirika komanso kokhazikika kwa masiwichi amakampani.

Kusintha kwa mafakitale a JHA TECH, mulingo wachitetezo umafika ku IP40, chipolopolo cha aluminiyamu, otetezeka komanso odalirika, kulumikizana kokhazikika, mitundu yonse, kuthandizira makonda ang'onoang'ono.
