Ukubonisa umlingani
Intambo ye-NHBV iyintambo yokwakha enezinto zokuvikela umlilo ezigoqwe nge-PVC. "NH" ichaza ukumelana nomlilo, "B" yintambo yokwakha, kanti "V" imele ukugqunywa nge-PVC. Isikhombisi sethusi esingenamoyela sinikeza ukudluliswa kukagesi okuhle kakhulu nokulahleka kwamandla okuphansi. Ukugqunywa nge-PVC kuqinisekisa ukumelana nomswakama, izinsipho, kanye namandla omshini. Ukuvota okulinganiselwe: 450/750V, kufanele kube kuhle ekusabalalisweni kwamandla aphansi. Yakhelwe njengekhebula elilodwa, ubukhulu besikhombisi buqala ku-1.5mm² kuya ku-10mm². Inzuzo enkulu: amandla azinzile ngesikhathi somlilo, aphelele ezinhlelweni zokuvikela umlilo, ukukhanyisa okuphuthumayo, amadivayisi abalulekile, kanye nokufakwa kwezintambo ngaphakathi ezindlini ezidinga ukumelana nomlilo. Ihambisana ne-GB/T 5023-2008 ne-GB/T 19666-2019 ukuze kube nokuphepha nokwethenjwa.
