Hoʻouna i kahi leka uilaHe kūpono nā kaula mana waena-voltage 6.35-11kV XLPE-insulated no nā pūnaewele hoʻolaha a i ʻole nā pūnaewele hoʻoili lua, e lawelawe pinepine ana ma ke ʻano he lako mana mua no nā pūnaewele kalepa, ʻoihana, a me nā hale noho kūlanakauhale. Hoʻohana ʻia lākou i nā ʻōnaehana me nā kahe hewa kiʻekiʻe i helu ʻia a hiki i 10kA/1 kekona. Loaʻa nā ʻano no nā kahe hewa kiʻekiʻe ma ke noi. Kūpono no nā noi static ma ka honua, i loko/waho, nā ducts kaula, i lalo o ka wai, a ma kahi i kau ʻole ʻia ai nā kaula i ke kaumaha mechanical koʻikoʻi a i ʻole ke kaumaha tensile. Ma muli o kona kumu pohō dielectric haʻahaʻa loa, e mau ana i kona ola lawelawe, a me nā waiwai insulating kiʻekiʻe o ka mea XLPE, hōʻike kēia kaula i ka hilinaʻi hana kiʻekiʻe.

ʻO nā pono o ka HV Cable Insulation XLPE:
1. Hana Kū'ē Wela:
ʻO XLPE me ka hoʻolālā ʻekolu-dimensional reticulated he hana kūpaʻa wela maikaʻi loa. ʻAʻole ia e pala a hoʻoheheʻe ʻia ma lalo o 300 ℃, hiki i ka mahana hana lōʻihi ke piʻi i 90 ℃, a hiki i ke ola wela ke hiki i 40 mau makahiki.
2. Hana Hoʻokaʻawale:
Mālama ʻo XLPE i nā ʻano insulation maikaʻi mua o PE, a hoʻonui hou ʻia ke kū'ē ʻana o ka insulation.
He liʻiliʻi loa kona waiwai tangent dielectric loss angle, a ʻaʻole ia e hoʻopilikia nui ʻia e ka mahana.
3. Nā Waiwai Mekanika:
Ma muli o ke kūkulu ʻia ʻana o nā pilina kemika hou ma waena o nā macromolecules, ua hoʻomaikaʻi ʻia ka paʻakikī, ka ʻoʻoleʻa, ke kū'ē ʻana i ka abrasion, a me ke kū'ē ʻana i ka hopena o XLPE, no laila e hoʻopiha ana i nā hemahema o PE i hiki ke maʻalahi i ke kaumaha o ke kaiapuni a me ka nahā.
4. Nā ʻano kū'ē kemika:
He ikaika ka pale ʻana o ka XLPE i ka waikawa a me ka alkali a me ke kūpaʻa ʻaila, a ʻo kāna mau huahana puhi ʻana he wai a me ke kalapona ʻokikene nui, ʻaʻole ia e hōʻino nui i ke kaiapuni a hoʻokō i nā koi o ka palekana ahi o kēia wā.
Kūkulu ʻana:
Kūkulu ʻana:ʻO ke kumu hoʻokahi, ʻekolu kumu, ʻekolu kumu 3 × 1.
Alakaʻi:Keleawe a alumini paha, poepoe i ulana ʻia, poepoe i ulana ʻia me ka paʻa.
Hoʻokaʻawale:XLPE a i ʻole TR-XLPE a i ʻole EPR.
Pale hao:Pale uea keleawe, pale lipine keleawe.
ʻUhi:ʻUpena metala kēpau, ʻupena alumini ʻōwiliwili, ʻupena keleawe ʻōwiliwili.
Nā mea kaua:Pale kaua uea alumini (AWA), pale kaua uea kila (SWA), pale kaua uea kila kuhiliʻole (SSWA).
