Uma usemakethe yeziguquli zamandla, iziteshi ezingaphansi ezihlangene kanye nama-switchgear, mhlawumbe unombuzo mayelana nokuthi ungazithenga kuphi. Kusuka ku-transformer kwemboni or global Ukuhweba inkampani, ingakulethela ukungabaza. Uma uthenga imikhiqizo embonini ye-transformer yase-China, ungathola inani eliphansi, kodwa ibhizinisi lingase lingabi lula kakhulu noma liphumelele. Uma uthenga imikhiqizo enkampanini yohwebo yomhlaba, ungathola ukukhululeka kwebhizinisi lomhlaba wonke, kodwa intengo mhlawumbe iphakeme kakhulu.

Ukukusiza ukuthi uxazulule le nkinga, i-SPL ibonakala yenza intengo ephusile kanye nokukhululeka kwebhizinisi lokuthunyelwa kwempahla kwamanye amazwe kwenzeke ngesikhathi esifanayo. I-SMTB, njengemboni ye-SPL, ingaqinisekisa iziguquli zamandla ezisezingeni eliphezulu nezinenani elizwakalayo, iziteshi ezingaphansi ezihlangene nama-switchgears. I-SPEEDLINK, njenge-ejenti yezohwebo yomhlaba wonke ye-SPL, inganikeza zonke izixazululo ekuqhubekeleni phambili kokuthunyelwa kwemikhiqizo kwamanye amazwe.
