1.Umsila omude onenetha + ukuqina okuphezulu kwentambo ye-PVC, ukugoba okunamandla aphezulu, ukusetshenziswa isikhathi eside ngaphandle kokwesaba ukugoba, valelisa ekulimaleni kwesixhumi esibonakalayo nokuqhekeka
2. I-copper core ehlanzekile evumelana nemvelo, intambo ye-PVC, ucingo luthambile, luqinile, akulula ukuhlanganisa, luthambile, lusezingeni eliphezulu futhi luthungwe, ukuxazulula inkinga yokukushaja kancane.
3.Inhlanganisela yokushaja nokudlulisa inganikeza ukudlala okuphelele ekusebenzeni futhi iqinisekise ukuvumelanisa kokushaja nokudluliswa kwedatha
