1. uwea keleawe:

Ke hoʻohana nei i ke keleawe electrolytic ma ke ʻano he mea maka, ua kapa ʻia ka uea keleawe i hana ʻia e ka hoʻolei mau ʻana a me ke kaʻina ʻōwili ʻana.Ua kapa ʻia ka uea keleawe me ka oxygen-free copper wire.

Haʻahaʻa oxygen keleawe uea oxygen maʻiʻo he 100 ~ 250ppm, keleawe maʻiʻo he 99.9 ~ 9.95%, conductivity mea 100 ~ 101%.

Oxygen free keleawe uea oxygen maʻiʻo he 4 ~ 20ppm, keleawe maʻiʻo he 99.96 ~ 9.99%, conductivity mea 102%.

ʻO ka gravity kūikawā o ke keleawe he 8.9g/cm3.

2. uwea alumini:

Hoʻopili ʻia ka uea alumini i hoʻohana ʻia no ka uea uila.ʻAʻole maʻa mau ka uea alumini i hoʻohana ʻia no ke kaula.

ʻO ka resistivity uila o ka alumini i hoʻohana ʻia no nā uea a me nā kaula he 0.028264 ω.Mm2 / m, a ʻo ka gravity kikoʻī o ka alumini he 2.703g/cm3.

3. Polyvinyl chloride (PVC)

Hoʻokumu ʻia ka plastic polyvinyl chloride ma ka resin polyvinyl chloride, e hoʻohui ana i nā ʻano hui like ʻole, e like me ka anti-aging agent, antioxidant, filler, brightener, flame retardant, etc.

Nā hiʻohiʻona o ka mea PVC:

ʻO nā waiwai mechanical maikaʻi loa, ke kūpaʻa corrosion kemika, non combustion, ke kū ʻana o ka wā maikaʻi, ka insulation uila maikaʻi, ka hana maʻalahi, etc.

ʻO nā hemahema o nā mea PVC:

(1) i ka wā e ʻā ai, nui ka uahi ʻawaʻawa;

(2) ʻAʻole maikaʻi ka hana ʻelemakule wela.

Loaʻa i ka PVC nā mea insulation a me nā kumu waiwai sheath.

4.PE:

Hana ʻia ka polyethylene me ka polymerization ethylene i hoʻomaʻemaʻe ʻia, e like me ka density hiki ke hoʻokaʻawale ʻia i ka polyethylene haʻahaʻa haʻahaʻa (LDPE), polyethylene medium density (MDPE), polyethylene high density (HDPE).

ʻO ka nui o ka polyethylene haʻahaʻa haʻahaʻa he 0.91-0.925 g / cm3.ʻO 0.925-0.94 g / cm3 ka nui o ka polyethylene density medium.ʻO ka nui o ka hdPE he 0.94-0.97 g/cm3.

ʻO nā pono o nā mea polyethylene:

(1) Ke kū'ē kū'ē kiʻekiʻe a me ka voltage;

(2) Ma kahi ākea o nā kaha alapine, he liʻiliʻi ka dielectric ε a me ka dielectric loss Angle tangent tgδ;

(3) maʻalahi, maikaʻi ke pale ʻana i ka lole;

④ ʻO ke kūpaʻa ʻelemakule maikaʻi, ka hana haʻahaʻa haʻahaʻa a me ka paʻa kemika;

⑤ ʻO ke kūpaʻa wai maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa;

⑥ ʻO ke kaula i hana ʻia me ia he māmā i ka maikaʻi a maʻalahi i ka hoʻohana ʻana a me ka waiho ʻana.

ʻO nā hemahema o nā mea polyethylene:

Maʻalahi e puhi i ka wā e pili ana me ka lapalapa;

He haʻahaʻa ka mahana palupalu.
