Uea pale wai no ka pauma hoʻoheheʻe wai
He hana pale wai radial a me ka longitudinal ke kaula wai ʻole a me ka hana pale wai: Hiki ke hana maʻamau i ka hohonu wai o 0-300 mika. Loaʻa iā ia ke kūpaʻa anu (- 40 ℃ - 80 ℃), ka pale UV, ka maʻalahi, ke kūpaʻa ʻana i ka ʻaʻahu, ka ikaika tensile, ke kūpaʻa aila a me nā waiwai kūikawā ʻē aʻe.
ʻAno Uea
1. E nānā i ka papa 2 o ka Appendix A no ke kū'ē DC o ke alakaʻi uwea i hoʻopau ʻia (papa R) (e like me gb3956).
2. E hoʻohana i nā mea pale wai ʻole kūikawā i lawe ʻia mai a me nā mea uhi.
3. Hoʻolālā kūikawā a me ke kaʻina hana.
4. ʻAʻole emi ka pale ʻana o ka insulation ma mua o 50m Ω / km ma 20 ℃.
5. ʻAʻole e haki ke kaula i hoʻopau ʻia ma lalo o ka hoʻāʻo uila AC 50 Hz 3.5 kV / 5 min.
Nā hiʻohiʻona o ke kaula:
1. Kūpono no ka wai kai a me ka wai maʻemaʻe.
2. Kūpono no 300 mika ma lalo o ka wai.
3. Ke kau ʻana a me ka hoʻohana ʻana ma o ka Paʻa a me ke Kelepona.
4. Loaʻa ka palapala sila o ke kaula ʻike wai kai anti.
