Kodi mukudziwa zambiri za zingwe zamagetsi zomwe zimagwiritsidwa ntchito kwambiri? (Gawo 2)

1. Chingwe Chogunda cha Ulusi wa OPGW Chopangidwa ndi Ulusi

Zogulitsazo OPGW Amagwirizanitsa ntchito za waya wolumikizira pansi ndi kulumikizana kwa kuwala, ndipo amagwiritsidwa ntchito makamaka pa mizere yolumikizirana ya makina atsopano otumizira magetsi amphamvu kwambiri a 35 KV ndi kupitirira apo, ndipo angagwiritsidwenso ntchito m'malo mwa mawaya omwe alipo kale a makina akale otumizira magetsi amphamvu kwambiri, kuwonjezera mizere yolumikizirana ya kuwala ndi kuyendetsa mafunde afupikitsa komanso kupereka chitetezo cha mphezi.

Makhalidwe a kapangidwe ka zinthu OPGW: chubu chosapanga dzimbiri cha chubu chowunikira ndi waya wamkuwa wophimbidwa ndi aluminiyamu, waya wa aluminiyamu wolukidwa ndi zingwe; chubu chosapanga dzimbiri cha chubu chowunikira chili pakati kapena mkati mwa wosanjikiza wolukidwa.

2. CHIKWANGWANI chachitsulo chodzichirikiza chokha

MASS (Metal Aerial Self-Supporting) ndi chingwe chofanana ndi OPGW (Open Point Ground Wire) chokhala ndi pakati pa mzere umodzi. Pokhapokha ngati tatchula mwanjira ina, waya wachitsulo wosweka nthawi zambiri amapangidwa ndi chitsulo cholimba, zomwe zimapangitsa kuti pakhale kapangidwe kosavuta komanso mtengo wotsika. MASS ndi chinthu chomwe chimalumikiza kusiyana pakati pa OPGW ndi ADSS (Advanced Optical Fiber Support). Ikagwiritsidwa ntchito ngati chingwe chodzithandizira chokha, mfundo zazikulu ndi mphamvu ndi kutsika, komanso chitetezo kuchokera ku ma conductor/mawaya oyandikana nawo ndi nthaka. Mosiyana ndi OPGW, sikufuna kuganizira za mphamvu yamagetsi yafupikitsa komanso mphamvu ya kutentha, OPPC, kutchinjiriza, mphamvu yonyamula magetsi, ndi impedance, ndi ADSS, sikufuna kuganizira za mphamvu yamunda pamalo oyika. Ntchito ya waya wachitsulo wakunja ndiyo kungosunga ndi kuteteza ulusi wamagetsi. Pankhani ya mphamvu yofanana yosweka, ngakhale MASS ndi yolemera kuposa ADSS, m'mimba mwake wakunja ndi wocheperako pafupifupi 1/4 kuposa wa chubu cha ADSS ndipo pafupifupi 1/3 wocheperako kuposa wa ADSS woyikidwa. Pa mulingo wofanana, mphamvu yosweka ndi kupsinjika kovomerezeka kwa ADSS ndizochepa kwambiri kuposa za MASS.
