ʻO ka hoʻohana ʻana a me ke ʻano o ka uwea insulated overhead

ʻO kauwea insulated overheadʻO nā huahana moʻo i haku ʻia me nā mea hoʻokele keleawe a me ka alumini (aluminium alloy), ka papa pale i loko, ka mea hoʻomake i ka wā a me ka papa pale o waho.Loaʻa iā lākou nā hiʻohiʻona hoʻoili mana o nā uwea mana a me nā waiwai mechanical ikaika o nā kaula overhead.Ke hoʻohālikelike ʻia me nā uea ʻole, loaʻa i kēia huahana nā hiʻohiʻona o ka hoʻomoe liʻiliʻi liʻiliʻi, palekana kiʻekiʻe a me ka hilinaʻi, a me ke kūpaʻa ʻelemakule maikaʻi loa.

Ka hoʻohana ʻana i nā kaula i hoʻopaʻa ʻia ma luna

ʻO nā huahana overhead insulated cable he moʻo huahana hou no ka hoʻouna ʻana i ka ikehu uila ma nā laina hoʻouna ma luna.Makemake ʻia lākou no ke kūkulu ʻana i ka mana mana a me ka hoʻololi ʻana o nā laina papahana hoʻouna 10kV.He mau huahana kūpono no ka mālama laina a me ka palekana.He kūpono nā huahana uea keleawe palupalu no nā alakaʻi haʻahaʻa transformer.

ʻO nā hiʻohiʻona o nā uwea insulated overhead

1. Helu uila: 0.6/1KV, 10KV;

2. ʻO ka mahana hana lōʻihi e ʻae ʻia o ke kaula: 70 ° C no ka polyvinyl chloride insulation a me 90 ° C no ka polyethylene insulation cross-linked.

3. I ka wā pōkole (ʻaʻole iʻoi aku ma mua o 5 kekona no ka manawa lōʻihi), ʻo ka wela kiʻekiʻe o ke kaula: ʻo 160 ° C ka pale ʻana o PVC, ʻo ka insulation polyethylene kiʻekiʻe he 150 ° C, a ʻo ka insulation polyethylene cross-linked he 250 ° C. ;

4. ʻAʻole e emi ka mahana ambient i ka wā e kau ana i ke kaula ma lalo o -20 ℃

5. 'O ka radius ku'u 'ae 'ia o nā uwea: uwea me ka helu volena ma lalo o 1KV: ina ka uwea waho anawaena (D) i emi ma mua o 25mm, 'a'ole ia e emi ma mua o 4D, a ina ke kaula waho anawaena (D) he 25mm a ma luna.

Pono e emi ma lalo o 6D;

I ka mālama ʻana i nā kaula, ʻaʻole loa e hui pū me nā waikawa, alkalis a me nā ʻaila mineral, a pono e mālama ʻia lākou ma kahi kaʻawale mai kēia mau mea corrosive;

ʻAʻole pono e loaʻa nā kinoea ʻino e hoʻopōʻino i ka insulation a hoʻopōʻino i ka metala i loko o ka hale kūʻai kahi i mālama ʻia ai nā kaula;

E ho'āʻo e hōʻalo i ka mālama ʻana i nā uwea ma ke ʻano ākea ma ka lewa.ʻAʻole ʻae ʻia nā pahu kelepona e waiho palahalaha;

Pono e ʻōwili mau ʻia ke kaula i ka wā e waiho ai (hoʻokahi manawa i kēlā me kēia 3 mahina i ke kauwela, a hiki ke hoʻonui ʻia e like me ke kūpono i nā kau ʻē aʻe).I ka wā e ʻōwili ai, e hoʻohuli i ka ʻaoʻao o ka pā waihona i lalo i mea e pale ai ka ʻili o lalo mai ka pulu a popopo.I ka wā e mālama ai, e nānā mau i ka paʻa ʻole o ke poʻo uwea;

ʻO ka manawa mālama o nā kaula i kaupalena ʻia i ka lā hale hana o ka huahana, ʻaʻole pono e ʻoi aku ma mua o hoʻokahi makahiki a me ka hapa a ʻaʻole ʻoi aku ma mua o ʻelua makahiki;

ʻAʻole loa e hoʻokuʻu i nā uwea a i ʻole nā ​​pahu uwea i loaʻa nā kaula mai nā wahi kiʻekiʻe i ka wā o ka lawe ʻana, ʻoi aku ka nui o nā haʻahaʻa haʻahaʻa (ma kahi o 5°C a ma lalo).ʻO ka hoʻolei ʻana a i ʻole ka hoʻokuʻu ʻana i nā kaula hiki ke hoʻomāhaʻi ka insulasi a me ka puʻu;

I ka hāpai ʻana i nā pūʻolo, pāpā loa ʻia ke hāpai ʻana i kekahi mau pā i ka manawa like.Ma luna o nā kaʻa, nā moku a me nā kaʻa kaʻa ʻē aʻe, pono e hoʻopaʻa ʻia nā pahu kelepona me nā ʻano kūpono e pale aku ai iā lākou mai ka hui ʻana a i ʻole ka hoʻohuli ʻana, a e pale aku i ka pōʻino mechanical i nā kaula.
