Haina 20kV wera whakaheke wheketere taputapu taura me nga kaihanga

20kV nga taputapu taura whakaheke wera

20kV nga hua raupapa taputapu waea ka taea te whakaheke wera, he pai mo te 12/20kV, 18/24kV kotahi-matua, toru-

polyethylene matua me nga taura hiko polyethylene hono-whakawhiti, he huinga parewai, he mana ahotea, he parepare,

whakaweto i roto i te kotahi. Ma nga taonga hiko me nga miihini pai, ka taea te whakamahi i nga momo taiao kino

nga tikanga mo te wa roa. Kei a ia nga painga o te taumaha ngawari me te whakaurunga ngawari. Ka whakamahia nuitia i roto i te hiko

hiko, hinu, matū, whakarewa, reriwe, tauranga me te hanga me etahi atu mara
