Ngati mugawa mu zomangamanga za telecom, chingwe cha ndodo cha telecom tower earth pa oda yanu yogula chimawoneka chosavuta ndipo sichichita zinthu molakwika. Ndodo ndi chinthu chotsika mtengo kwambiri mu dongosolo la grounding, komabe chimasankha ngati siteshoni ya maziko ipulumuka nyengo yake yoyamba ya mphezi - komanso ngati...
Mukatumiza ESE lightning arrester kuchokera ku China, katunduyo amachotsedwa kapena kusungidwa pa zikalata zisanu ndi zinayi: pepala lofotokozera lomwe lili ndi magawo oyesedwa, lipoti loyesa la labotale lotchula labu yomwe yapereka, satifiketi ya zinthu za alloy ya ndodo, invoice yamalonda yomwe kufotokozera kwa malonda ake kumafanana...
Buku lotsogolera la woyang'anira za ma welds a exothermic omwe alephera — zifukwa zisanu zomwe zimayambitsa njira, njira yodziwira matenda, ndi njira yodziwira kulephera kwa weld yomwe mungathe kuyigwiritsa ntchito musanachotse chilichonse. TL;DR — Yankho la munda patsogolo Kulephera kwakukulu kwa weld ya exothermic "mwadzidzidzi" sikumachitika mwadzidzidzi ...

Kwa opanga mafuta ndi gasi, zinthu zotetezera cathodic ndizogwiritsidwa ntchito zomwe zimamangirira ma test leads, ma anode cables ndi ma bonding conductors ku payipi yobisika - ndipo chisankho chogula chimadalira zinthu zitatu: ufa wothira thermit womwe umagwirizana ndi zinthu zanu za kondakitala ndi kukula kwake...
Timamva nkhani ya exothermic welding vs clamps ikukambirana sabata iliyonse, ndipo chinthu chofunikira kwambiri si ntchito ya tsiku loyamba - zonse ziwiri zimatha kuyeza bwino kwambiri pakuyambitsa. Ndi zomwe zimachitika pa kukana kulumikizana kwa nthaka pambuyo pa zaka 20 za chemistry ya nthaka, cycling ya kutentha ndi ma currents olakwika. Ine ndine Jane Yang, wogulitsa...
Africa ili pakati pa ntchito yaikulu kwambiri yopezera magetsi kumidzi m'mbiri yake, ndipo kilomita iliyonse ya mzere watsopano, chosinthira chilichonse chogawa magetsi ndi gridi iliyonse yaying'ono imafunika zipangizo zopangira nthaka zomwe makampani amagetsi angadalire kwa zaka zambiri. Pofika mu 2024, anthu pafupifupi 600 miliyoni ku sub-Saharan Africa — 47% ya...
