Application

ASTM 25kV SAC Cable System inoshandiswa kugovera yepuraimari kana yechipiri ine nzvimbo shoma iripo.
Iyi SAC Cable inokodzera ma voltages anosvika 25,000 volts.
Waya yemuti iyi inodzivirirwa kudzivirira yakananga mapfupi maseketi uye kwechinguvana flashovers kana kukwira miti kana zvimwe zvinhu zvakasangana nemakondakita akadaro.

Zvivakwa

Tambo imwe chete ine ACSR conductor, 3-layer extruded shield uye yekuvhara system, inosanganisira extruded semiconducting thermoplastic conductor nhovo, uye 2-layer yekufukidza.
Iyo yekuvharisa yemukati layer ndeye yakaderera-, yepakati- kana yakakwira-density polyethylene (LDPE, MDPE kana HDPE), ukuwo yekunze dhizaini isingaite zvepakati- kana yakakwirira-density polyethylene (TK-MDPE kana TK-HDPE).
Zvose zvikamu zvakabatanidzwa pamwe chete.

Kondakita:
AAC (1350-H19, compact stranded).

Conductor Shield:
Extruded semiconducting thermoplastic shield iyo inobvisa mahara kubva kune conductor uye yakasungirirwa kuvharo.

Chifukidziro chemukati nekunze:
2-layer yakaderera-, yepakati- kana yakakwira-density polyethylene inovhara (LDPE, MDPE kana HDPE), uko kunze kwekunze kusingaite track-resistant (TK-MDPE kana TK-HDPE).Zvose zvikamu zvakabatanidzwa pamwe chete.Iyo yekunze yakaturikidzana ichave nhema kana grey, isingachinji kuchiedza chezuva uye inoshingirira nzira.
