1. waya yemhangura:

Uchishandisa electrolytic mhangura seyakagadzirwa, waya yemhangura inogadzirwa nekuramba ichikanda uye kukunguruka maitiro inonzi yakaderera oksijeni copper waya.Waya yemhangura inonzi waya yemhangura isina oxygen.

Low oxygen copper wire oxygen content is 100 ~ 250ppm, mhangura inokwana 99.9 ~ 9.95%, conductivity i100 ~ 101%.

Oxygen yemahara copper wire okisijeni yemukati ndeye 4 ~ 20ppm, mhangura yemukati ndeye 99.96 ~ 9.99%, conductivity i102%.

Iyo chaiyo gravity yemhangura ndeye 8.9g/cm3.

2. Aluminium waya:

Waya yealuminium inoshandiswa kuita waya yemagetsi inonamirwa uye yakapfava.Aluminium waya inoshandiswa patambo haiwanzo kupfava.

Iyo yemagetsi resistivity yealuminium inoshandiswa kune waya netambo inofanira kuva 0.028264 ω.Mm2/m, uye iyo chaiyo giravhiti yealuminium inofanira kunge iri 2.703g/cm3.

3. Polyvinyl chloride (PVC)

Polyvinyl chloride plastiki yakavakirwa pa polyvinyl chloride resin, ichiwedzera akasiyana-siyana ekubatanidza agent yakasanganiswa, senge anti-aging agent, antioxidant, filler, brightener, flame retardant, etc., density yayo inenge 1.38 ~ 1.46g/cm3.

Maitiro ePVC zvinhu:

Yakanakisa mechanicha zvivakwa, makemikari corrosion kuramba, kusapisa, kunaka kwemamiriro ekunze kuramba, kunaka kwemagetsi insulation, kugadzirisa nyore, nezvimwe.

Kuipa kwePVC zvinhu:

(1) pakutsva, hutsi hwakawanda hune chepfu hunobuda;

(2) Kusashanda zvakanaka kwekuchembera kwekushisa.

PVC ine insulation zvinhu uye sheath zvinhu mapoinzi.

4.PE:

Polyethylene inogadzirwa neyakacheneswa ethylene polymerization, zvinoenderana nehukuru inogona kukamurwa kuita yakaderera density polyethylene (LDPE), yepakati density polyethylene (MDPE), yakakwira density polyethylene (HDPE).

The density of low density polyethylene is 0.91-0.925 g/cm3.The density yepakati density polyethylene i 0.925-0.94 g/cm3.Kuwanda kwehdPE ndeye 0.94-0.97 g/cm3.

Zvakanakira zve polyethylene zvinhu:

(1) High insulation kuramba uye voltage kuramba;

(2) Mumhando dzakasiyana-siyana dzemabhendi, dielectric inogara ε uye dielectric kurasikirwa Angle tangent tgδ idiki;

(3) inochinjika, yakanaka kupfeka kuramba;

④ Yakanaka kupisa kuchembera kuramba, yakaderera tembiricha kuita uye kugadzikana kwemakemikari;

⑤ Kuramba kwakanaka kwemvura uye kunyura kwakadzika;

⑥ Tambo yakagadzirwa nayo yakareruka mumhando uye iri nyore mukushandisa nekukandira.

Kuipa kwe polyethylene zvinhu:

Zviri nyore kupisa kana wasangana nemurazvo;

Kunyorova tembiricha yakaderera.
