China ye nsi esinga okufulumya n’okutunda ebweru w’eggwanga ebyuma ebikuba ebikoligo bya layini z’amasannyalaze. Nga ekitundu ekikulu eky’ebikozesebwa ebya vvulovumenti eya waggulu, ebipande by’ekikoligo bikoze kinene mu kutambuza amasannyalaze aga vvulovumenti eya waggulu-(UHV), okugatta emikutu gy’amasannyalaze agazzibwawo, emikutu egy’amagezi, n’emikutu gy’okutambuza amasannyalaze egy’okusalako-ensalo mu nsi yonna. Layini za UHV ziteeka obwetaavu obw’amaanyi ennyo ku maanyi g’ebyuma, obutuufu bw’ebituli, n’okuziyiza obukoowu bwa fittings. Ebipande by’ekikoligo eby’ennono ebiriko sitampu bigenda bikyusibwa mpolampola ne bifuulibwa ebikondo ebikoleddwa mu kyuma, ebijingirire, n’ebyawuddwamu emirundi mingi- (4/6/8 split). High{13}}end yoke plates zibeera za bbeeyi 30%-100% okusinga yoke plates eza bulijjo, ne zifuuka core driver of market growth.
Okwongera ku busobozi bw’okutambuza n’okukendeeza ku kufiirwa kwa corona, layini za 500kV n’okudda waggulu zitera okukozesa kondakita 4-split, 6-split, ne 8-split, nga kyetaagisa ebipande by’ekikoligo eby’enjawulo ebikutuddwamu ebingi. Mu mwaka gwa 2025, akatale k’ekikoligo kya layini y’amasannyalaze mu ggwanga kaali nga akawumbi kamu n’obukadde 500, nga kakola ebitundu 35% ku katale k’ekikoligo kwonna. Kiteeberezebwa nti ekitundu kino kijja kweyongera okutuuka ku bitundu 50% omwaka 2030 we gunaatuukira, nga kisukka obuwumbi bwa Yuan 4.
Okukola ensibuko z’amasoboza empya kivuddeko obwetaavu bw’okukola Power Line Yoke Plates ezikoleddwa ku mutindo. Ebifo eby’okufuuyira omunnyo omungi n’obunnyogovu ku nnyanja byetaaga okulongoosa-dip galvanizing ne pasivation treatment ku pulati, okukakasa obulamu obuziyiza okukulukuta obw’emyaka egisukka oba obwenkana emyaka 30. Okumanyibwa amangu kw’amabibiro g’amasannyalaze agasaasaanyizibwa, amabibiro g’amasannyalaze agatereka amaanyi, n’amabibiro g’amasannyalaze ag’omubiri (virtual power plants) kwe kuvuga okulongoosa emikutu gy’okusaasaanya vvulovumenti entono/eza wakati-, ekivaamu okweyongera buli kiseera mu bwetaavu bwa pulati ezitazitowa ezisaanira obusobozi obutono n’embeera ez’enjawulo. Mu layini z’amasannyalaze eziriwo mu nsi yonna, ebitundu ebisukka mu 30% bimaze emyaka egisoba mu 20 nga bikola, nga waliwo ensonga ezimanyiddwa ennyo ez’okukaddiwa n’okukulukuta kw’ebikozesebwa. Okulongoosa layini enkadde eza vvulovumenti eya waggulu-kukolebwa mu kiseera kye kimu mu Amerika, Bulaaya, ne Buyindi, ekivaako okukula okunywevu mu bwetaavu bwa pulati ezikyusibwa, nga zikola ebitundu ebisukka mu 40% ku bwetaavu bwa pulati zonna.
Okwongera ku bungi bw’ebipande by’ekikoligo kya layini z’amasannyalaze ebweru w’eggwanga, kkampuni yaffe egenda mu maaso n’okulongoosa enkola zaayo ez’okufulumya, ng’egoberera omutindo ogwa waggulu-ogw’enkomerero, ogw’amagezi, era ogukoleddwa ku mutindo. Ebikondo by’ekikoligo eby’ennono okusinga birimu ebikondo eby’enjuyi essatu ne square, ebikolebwa nga bakozesa enkola ya steel plate stamping ne hot-dip galvanizing processes, ezikozesebwa mu layini za 110kV-220kV.
Okujja kwa high-end yoke plates kuwambye akatale akanene. Multi-split yoke plates zikozesa okusala CNC, okusima CNC, n’enkola z’okulaganya okutwalira awamu, okutuuka ku butuufu bw’ekifo ky’ekinnya ekya ±0.05mm, ezikozesebwa mu layini 500kV n’okudda waggulu; ebipande ebiyungiddwa emirundi ebiri-bikozesa enkola z’okukuŋŋaanya ebipande eby’emirundi ebiri, okuweta, n’okukendeeza ku situleesi, ne bituuka ku busobozi bw’okusitula omugugu-500kN, obukozesebwa mu miguwa gy’okusika kwa vvulovumenti eya waggulu ennyo; forged connecting plates utilize forging, heat treatment, and machining processes, okutuuka ku 30%+ amaanyi aga waggulu okusinga ebitundu ebiteekeddwako sitampu n'okuziyiza okukoowa okulungi ennyo, ezikozesebwa mu ultra-high voltage, long-span, ne critical lines.
Mu kiseera ky’okufulumya, Power Line Yoke Plate ebadde elongooseddwa mu bintu, nga ekozesa ekyuma eky’amaanyi amangi-mu kifo kya Q355, ekivuddemu okukendeeza ku buzito ebitundu 15% n’amaanyi okweyongera ebitundu 30%. CNC machining edda mu kifo ky’okusiba sitampu ey’ennono, okulongoosa ennyo obutuufu bw’ebinnya n’okukwatagana. Okutwalira awamu okujjanjaba ebbugumu kumalawo situleesi ey’omunda, okulongoosa okuziyiza obukoowu ebitundu ebisukka mu 50%. Hot-dip galvanizing egobererwa closed pasivation etuuka ku kigero ky’okuziyiza okukulukuta ekya ASTM A153 n’okugezesa okufuuyira omunnyo okusukka oba okwenkana essaawa 1000. Empeereza y’okukola dizayini y’ebiyungo, okulongoosa, n’okugiteeka mu ngeri ey’enjawulo eweebwa ku mitendera gya vvulovumenti egy’enjawulo, ennamba z’okugabanyaamu kondakita, n’embeera z’ettaka okutuukiriza ebyetaago bya bakasitoma ssekinnoomu n’okutumbula obwesigwa bwa bakasitoma.
Nga ekitundu ekikulu ekitwala omugugu-mu layini z’amasannyalaze, ensonga z’omutindo ku Power Line Yoke Plate ziyinza okuvaako obubenje obw’amaanyi mu by’okwerinda nga layini okugwa, okugwa kw’omunaala, n’okuva kw’amasannyalaze amanene-. Akatale k’ensi yonna kalina ebisaanyizo ebikakali ku maanyi g’ebyuma, okukola obulungi mu bukoowu, n’okugumira okukulukuta. Omutindo gw’ebintu ogutali ku mutindo gujja kuvaamu okuddamu, okwewozaako, n’okwonooneka kw’ekibinja ky’ebintu. Enkola yaffe ey’okuddamu mulimu: okulondoola omutindo mu ngeri enkakali, okugezesa 100% okutali-okusaanyaawo, okukakasa okw’ekibiina eky’okusatu-, n’empeereza enzijuvu oluvannyuma lw’okutunda.
