Izikhululo zetheminali zineempawu ezisisiseko ezi-3: iimpawu zoomatshini, iimpawu zombane kunye neempawu zokusingqongileyo.

　　1. Ukusebenza kombane

　　Xa itheminali isetyenziswa njengocingo lokuqhagamshela, okokuqala, ukusebenza kufuneka kube kukusebenza kombane.

　　Ikakhulu ibandakanya: ukuxhathisa ukudibana, ukuxhathisa ukugquma kunye namandla e-dielectric.

　　1. Ukuchasana noqhagamshelwano, izihlanganisi zombane ezikumgangatho ophezulu kufuneka zibe nokumelana noqhagamshelwano oluphantsi kwaye oluzinzileyo.

　　2. abafowunelwa kunye naphakathi kwabafowunelwa kunye neqokobhe.

　　3. Amandla edielectric ngamandla ombane okumelana kunye ne-dielectric standstand voltage.

　　2. Mechanical properties

　　Ukusebenza komatshini ikakhulu kubandakanya amandla ofakelo kunye nobomi bomatshini isidibanisi. Ukufakwa kunye nokukhupha amandla kunye nobomi bomatshini be-terminal bunxulumene nesakhiwo soqhagamshelwano (uxinzelelo olulungileyo), umgangatho wokugquma wecandelo loqhagamshelwano (i-coefficient ye-sliding friction) kunye nokuchaneka komlinganiso (ulungelelwaniso) lolungiselelo loqhagamshelwano.

3. Ukusebenza kwendalo

　　Iimpawu zokusingqongileyo eziqhelekileyo ziquka: ukuxhathisa ubushushu, ukumelana nokufuma, ukuxhathisa isitshizi setyuwa, ukungcangcazela kunye nokuxhathisa ukothuka, njl.
