1. Taura Whenua Hiko OPGW
Ngā hua OPGW Ka whakauruhia e rātou ngā mahi a te waea whenua me te whakawhitiwhiti kōrero whatu, ā, e whakamahia ana mō ngā raina whakawhitiwhiti kōrero o ngā pūnaha tuku hiko teitei hou o runga ake i te 35 KV me runga ake, ā, ka taea hoki te whakamahi hei whakakapi i ngā waea whenua o ngā pūnaha tuku hiko teitei tawhito, hei whakanui ake i ngā raina whakawhitiwhiti kōrero whatu me te kawe i ngā iahiko poto me te whakarato i te tiaki uira.
Ngā āhuatanga hanganga o ngā hua OPGW: waeine muka whatu ngongo kowiri tira me te waea parahi whakakikoruatia ki te konumohe, waea koranu konumohe whiri me te taura; kei waenganui, kei roto rānei i te paparanga whiri te waeine muka whatu ngongo kowiri tira.
2. Taura whatu whakarewa tautoko-ā-ia-koe a MASS
Ko te MASS (Metal Aerial Self-Supporting) he taura rite te hanganga ki te OPGW (Open Point Ground Wire) me te matua kotahi-paparanga. Ki te kore e tohua, ko te waea whakarewa he mea hanga ki te maitai kua whakapūmautia, ka hua ake he hanganga māmā me te utu iti iho. Ko te MASS he hua e hono ana i te āputa i waenga i te OPGW me te ADSS (Advanced Optical Fiber Support). Ina whakamahia hei taura whatu tautoko-whaiaro, ko ngā mea matua e whakaarohia ana ko te kaha me te heke, me te āputa haumaru mai i ngā kaiārahi whenua/waea tata me te whenua. Kāore i rite ki te OPGW, kāore e hiahiatia he whakaaro ki te iahiko poto me te kaha wera, te OPPC, te whakamarumaru, te kaha kawe-iahiko, me te aukati, me te ADSS, kāore e hiahiatia he whakaaro ki te kaha o te mara i te wāhi tāutanga. Ko te mahi a te waea whakarewa o waho ko te whakauru me te tiaki i te muka whatu anake. Mēnā he kaha whati rite, ahakoa he taumaha ake te MASS i te ADSS, ko tōna diameter o waho he tata ki te 1/4 te iti iho i te ngongo matua ADSS, ā, tata ki te 1/3 te iti iho i te ADSS paparanga. Mō te diameter ōrite, he iti iho te kaha whati me te ahotea whakaaetia o te ADSS i ō te MASS.
