I-China 20kV incipha ukushisa kwekhebula izesekeli ifektri nabakhiqizi

Izesekeli zekhebula lokunciphisa ukushisa elingu-20kV

Incazelo emfushane:

20kV imikhiqizo yochungechunge lwezisekeli zekhebula ezincibilika ukushisa, ilungele i-12/20kV, 18/24kV single-core, ezintathu-

I-polyethylene eyinhloko kanye nezintambo zamandla ze-polyethylene ezixhunywe ngokuphambanayo, isethi engangeni manzi, isilawuli sokucindezeleka, isivikelo,

ukwahlukanisa kwelinye. Ngezakhiwo ezinhle zikagesi nezemishini, ingasetshenziswa endaweni ehlukahlukene enokhahlo

izimo isikhathi eside. It has izinzuzo isisindo ukukhanya kanye ukufakwa lula. Isetshenziswa kakhulu kugesi

amandla, uphethiloli, amakhemikhali, i-metallurgy, ujantshi wesitimela, amachweba kanye nezokwakha kanye neminye imikhakha
