Kaula Concentric SANS 1507 SNE
ʻO nā kaula concentric SANS 1507 SNE he mau kaula hoʻohui lawelawe haʻahaʻa-voltage i hana ʻia e like me ke South African National Standard (SANS) 1507-6.
Kūlike nā kaula SNE Tongxin me nā kikoʻī o SANS 1507, ka mea e uhi ana i nā kaula XLPE (cross-linked polyethylene) i hoʻopaʻa ʻia me ka uhi polyethylene.
Hoʻohana ʻia kēia mau kaula no nā lako mana me nā ʻōnaehana Protective Multiple Earthing (PME), kahi i hui pū ʻia ai ka Protective Earth (PE) a me Neutral (N) - i ʻike ʻia ʻo PEN - e hoʻohui i ka neutral-a-honua i hui pū ʻia i ka honua maoli ma nā wahi he nui e hōʻemi i ka pilikia o ka haʻalulu uila i ka hanana o ka PEN haki. -
Kaula Concentric SANS 1507 CNE
Ua kūlike nā kaula concentric SANS 1507 CNE me nā kūlana o ʻApelika Hema a ua hoʻolālā kūikawā ʻia no nā pilina lawelawe kūloko hilinaʻi.
He alakaʻi keleawe paʻakikī i hoʻopaʻa ʻia i loko o ke kaula poepoe, XLPE i hoʻopaʻa ʻia me nā alakaʻi honua ʻōlohelohe i hoʻonohonoho ʻia ma ke ʻano concentric. Uea hoʻohui lawelawe hale 600/1000V i uhi ʻia me ka polyethylene. Hoʻomoe ʻia ke kaula nylon ma lalo o ka uhi. Hana ʻia e SANS 1507-6. -
Uea Concentric Alumini Maʻamau ASTM/ICEA-S-95-658
Ho'ākāka 'o ASTM/ICEA-S-95-658 i nā koi kūkulu 'ana no nā kaula alumini concentric neutral ha'aha'a-voltage e kūlike me ke National Electrical Code (NEC).
Hiki ke hoʻohana ʻia kēia ʻano alakaʻi ma nā wahi maloʻo a pulu, kanu pololei ʻia a i waho paha; ʻO kona mahana hana kiʻekiʻe loa he 90 ºC a ʻo kona volta lawelawe no nā noi āpau he 600V. -
Uea Kūlike Keleawe Maʻamau ASTM/ICEA-S-95-658
ʻO kēia kūlana e pili ana i ke ʻano o ke kaula i wehewehe ʻia e ke kūlana hui ASTM a me ICEA (Insulated Cable Engineers Association).
Ke wehewehe nei ke kūlana ASTM/ICEA-S-95-658 i nā kaula keleawe concentric me kahi kumu alakaʻi keleawe, kahi alakaʻi kūlike concentric keleawe a alumini paha, a me kahi ʻūpā pale.
Hana ʻia ke kaula keleawe ʻo Copper Core Concentric i hoʻokahi a ʻelua paha mau alakaʻi waena paʻa a i ʻole ke keleawe palupalu i wili ʻia, me ka PVC a i ʻole XLPE insulation, ka alakaʻi waho i hana ʻia me kekahi mau uea keleawe palupalu i wili ʻia i loko o kahi ʻōwili a me ka ʻeke waho ʻeleʻele i hiki ke hana ʻia me PVC, thermoplastic polyethylene a i ʻole XLPE.
