Intambo ye-RVS iyintambo kagesi enezintambo ezimbili eziguquguqukayo echazwa imodeli yayo: "R" imele ukuguquguquka, "V" imele i-PVC (polyvinyl chloride) insulation, kanti "S" imele isakhiwo esihlukene/esihlanjiwe, esinezintambo ezimbili zobhedu olungenayo umoya oluhlanjiwe ndawonye ukuze kuncishiswe ukuphazamiseka kukagesi. Izintambo zobhedu ezihlukene zekhwalithi ephezulu ziqinisekisa ukudluliswa kukagesi okuhle kakhulu, ukulahleka kwamandla okuphansi, nokuguquguquka okungcono, okuvumela ukuhanjiswa kalula ezindaweni ezincane, emakhoneni aqinile, nasemigudwini eyinkimbinkimbi yokufakwa okulula. Isendlalelo sayo esiqinile se-PVC insulation sinikeza i-insulation kagesi ethembekile, ukumelana nomswakama, nokumelana nokuguga, sisekela izinga lokushisa elihlala njalo lokusebenza lika-70℃ kanye nevoltheji elilinganiselwe lika-300/500V, ngokuhambisana ngokuphelele namazinga omhlaba wonke njenge-IEC 60227 kanye nemigomo kazwelonke efana ne-GB/T 5023-2008. Itholakala ngamasayizi ajwayelekile ezintambo kusuka ku-0.5mm² kuye ku-2.5mm² kanye nezingxube zemibala ehlukahlukene, isetshenziswa kabanzi ezintweni zikagesi zasekhaya, imijikelezo yokulawula, izinhlelo zokukhanyisa, ama-intercoms, izinhlelo ze-alamu, kanye nezintambo zangaphakathi ezingaphansi kwamavoltheji ezakhiweni zokuhlala nezamabhizinisi, ihlinzeka ngesisombululo sokufakwa esizinzile, esiphephile, nesiguquguqukayo.
