1. Insinga y'ubutaka ya OPGW Fiber Composite
Ibicuruzwa OPGW Zihuza imikorere y'insinga zo hasi n'itumanaho ry'amatara, kandi zikoreshwa cyane cyane ku mirongo y'itumanaho ya sisitemu nshya zo kohereza umuriro mwinshi hejuru ya 35 KV no hejuru, kandi zishobora no gukoreshwa mu gusimbuza insinga zisanzwe zo kohereza umuriro hejuru za sisitemu zishaje zo kohereza umuriro mwinshi hejuru, kongera imiyoboro y'itumanaho ry'amatara no kuyobora imiyoboro migufi no kurinda inkuba.
Imiterere y'imiterere y'ibicuruzwa OPGW: igice cy'icyuma gikozwe muri fibre optique hamwe n'insinga z'umuringa zipfutse muri aluminiyumu, insinga za aluminiyumu zipfutse hamwe n'insinga; igice cy'icyuma gikozwe muri fibre optique kiri hagati cyangwa imbere mu gice cy'imbere cy'urwego rupfutse.
2. MAS Insinga y'icyuma yishingikirizaho ubwayo
MASS (Metal Aerial Self-Supporting) ni insinga isa n’iya OPGW (Open Point Ground Wire) ifite igice kimwe cy’imbere gifunganye. Keretse iyo byavuzwe ukundi, insinga y’icyuma ifunganye isanzwe ikozwe mu byuma bya galvanised, bigatuma imiterere yayo yoroshye kandi ihendutse. MASS ni ikintu kigabanya icyuho kiri hagati ya OPGW na ADSS (Advanced Optical Fiber Support). Iyo ikoreshejwe nk'insinga ya optique yishingikirizaho, ibintu by'ingenzi ni imbaraga n'uburemere, ndetse n'umutekano uva ku nsinga/insinga z'ubutaka zegeranye n'ubutaka. Bitandukanye na OPGW, ntabwo isaba gusuzuma imbaraga z'amashanyarazi n'ubushyuhe, OPPC, insulation, ubushobozi bwo gutwara umuriro, na impedance, na ADSS, ntabwo isaba gusuzuma imbaraga z'ubutaka aho ishyirwa. Imirimo y'insinga y'icyuma yo hanze ni ugushyira no kurinda fibre y'amashanyarazi gusa. Mu gihe cy'imbaraga zisa, nubwo MASS iremereye kurusha ADSS, umurambararo wayo wo hanze ni hafi 1/4 cy'umuyoboro w'ibanze wa ADSS kandi hafi 1/3 cy'umuyoboro w'imbere wa ADSS. Ku murambararo usa, imbaraga zo kumenagura n'umuvuduko wemewe wa ADSS biri hasi cyane ugereranyije n'ibya MASS.
