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, ukulahlekelwa kwamandla okuphansi, nokuguquguquka okungcono, okuvumela ukuhanjiswa okulula ezindaweni eziminyene, emakhoneni aqinile, nasemigudwini yezintambo eyinkimbinkimbi ukuze kufakwe kalula. Isendlalelo sayo se-PVC esiqinile sinikeza i-insulation kagesi ethembekile, ukumelana nomswakama, nokumelana nokuguga, sisekela izinga lokushisa elihlala njalo lokusebenza lika-70℃ kanye nevoltheji elilinganiselwe lika-300/500V, lihambisana ngokugcwele namazinga omhlaba njenge-IEC 60227 kanye nemigomo kazwelonke efana ne-GB/T 5023-2008. Itholakala ngamasayizi avamile ezintambo kusuka ku-0.5mm² kuye ku-2.5mm² kanye nezingxube zemibala ehlukahlukene, isetshenziswa kabanzi kumadivayisi asekhaya, imijikelezo yokulawula, izinhlelo zokukhanyisa, ama-intercom, izinhlelo ze-alamu, kanye nezintambo zangaphakathi ezingaphansi kwamavoltheji ezakhiweni zokuhlala nezamabhizinisi, ihlinzeka ngesisombululo sezintambo esizinzile, esiphephile, nesiguquguqukayo.
