Paerewa ā-motu mō ngā pito pēhi matao iti-ngaohiko

JB/T 2436.1-2020 Parahi Ngā Pūrua Whakakōpiri mō ngā Kaiārahi Wāhanga 1: Ngā Pūtake Whakapiko Parahi mō ngā Kaiārahi o te 0.5mm² ki te 6.0mm² He pai mō ngā pūtake whakapiko tahanga me ngā pūtake kua whakamahanatia mō ngā kaiārahi whakawhiti-wāhanga iti. Ka whakamahia ngā pūtake kua whakamahanatia mō ngā ara iahiko me te ngaohiko whakatauranga o te 660V me raro iho.
JB/T 2436.2-2020 Ngā Pūrua Kutikuti Parahi mō ngā Kaiārahi Wāhanga 2: Ngā Pūrua Kutikuti Parahi mō ngā Kaiārahi o te 10mm² ki te 300mm² He pai mō ngā pūrua kutikuti parahi tahanga mō ngā kaiārahi whakawhiti-wāhanga nui, e whakamahia whānuitia ana i roto i te whakahaere hiko, te tohatoha, me ētahi atu taputapu hiko katoa.
GB/T 17196-2017 Ngā Pūrere Hononga Ngā Pūrere Hononga Tere Papatahi mō te Hononga i ngā Kaiārahi Parahi—Ngā Whakaritenga Haumaru E tohu ana i ngā whakaritenga haumaru mō ngā pūrere hono tere papatahi mō te hono i ngā kaiārahi parahi, he pūtake nui tēnei mō te mahi haumaru o te hua.
GB/T 4025-2010 (Paerewa Tāutuhi) E tohu ana i ngā tikanga tāutu o ngā pito taputapu hiko, tae atu ki te tohu mā te whakamahi i ngā tae, ngā tohu whakairoiro, ngā pūnaha ārepa rānei.

Ko ngā pito pēhi-matao, e mōhiotia ana ko ngā pito kume, he wāhanga ka taea te hono hiko me te kore e whakapiripiri. He tino māmā, he pono hoki te kaupapa mahi: ka tangohia te ārai o te waea, ka whakaurua ki roto i te ngongo whakarewa o te pito, ā, ka pēhia mā te whakamahi i tētahi taputapu kume motuhake, ka huri te āhua o te ngongo whakarewa, ka takai pūmau ki te waea, ka hanga he hononga haumaru me te kawe hiko tino pai.

Ko te take e taea ai e ngā pito pēhi-matao te noho hei "kaha matua" i roto i ngā hononga hiko, nā ēnei āhuatanga matua:
Tāutanga tere me te whai hua: Ki te whakatauritea ki te whakarewa, he tino tere te tukanga whakakoi, he torutoru hēkona noa iho hei whakaoti i tētahi pūwāhi hononga kounga teitei, he mea tino pai mō ngā mahi waea nui.
Hononga pono, pumau hoki: Ka taea e te whakapiko kounga teitei te hanga hononga ā-hau, ka ārai i te waikura waea, ka whakarato i te ātete wiri me te ātete kume, kia mau ai te mahi roa.
Te tiaki watea, ngāwari hoki: Ka taea te wetewete ngāwari i ngā hononga kume, ka māmā ake ai te tiaki taputapu me te whakakapi waea, he painga tēnei e kore e taea te rite e te whakarewa.
Whānui te whakamahinga: Ahakoa he waea whakahaere angiangi pērā i te makawe, he taura hiko matotoru pērā i te maihao, kei reira ngā whakaritenga e rite ana mō ngā pito pēhi matao e wātea ana.
