Relipi e sebetsa joang ho fapana le ea motho ea tsamaeang?
Li-slip rings li fana ka khokahanyo e tsoelang pele ea motlakase ka liring tsa conductive tsa 360{{3}degree. Bahahlauli ba sebelisa mehele e arohaneng e fetolang likhokahano ha ba ntse ba potoloha, ba fetolela AC ho DC ka lienjineri kapa DC ho AC ka lijenereithara.

Mantsoe ana ha a feto-fetohe ho sa tsotellehe pherekano ka linako tse ling.
Ke eng e khethollang palo e kholo ea li-circuits ka har'a selikalikoe se thellang?
Meeli ea sebaka sa 'mele palo ea potoloho. Potoloho e 'ngoe le e 'ngoe e hloka selikalikoe se inehetseng, lekhalo la insulate, le kopano ea borashe. Li-slip rings tse tloaelehileng tsa indasteri li amohela li-circuits tse 2-24 hangata, leha likarolo tse ikhethileng li fihla 100+ li-circuits. Meetso e nyane ea li-capsules e fihla ho li-circuits tse 56 kahare ho bophara ba 45mm. Ho eketsa li-circuits ho eketsa bolelele ba axial (bakeng sa meralo e tloaelehileng) kapa bophara (bakeng sa tlhophiso ea li-pancake).
