API 5CT tuubada daasadaha

Daboolku waa tuubo dhexroor weyn ah oo la geliyo oo la geliyo qayb dhawaan la qoday oo ka mid ah riigga
lagu hayo sibidh. Oo waxaan bixinaa kasbado kala duwan oo aan kala go 'lahayn laga bilaabo 4-1 / 2 ''-20'' ee fasalka H40, J55, K55,
N80, L80, C95, P110 iwm. Dhererka daboolku waa R1, R2, R3, oo leh dunta BTC, LTC, STC. Sida xoogga ah
daboolka birta ah waxaa loo qaybin karaa heer bir oo kala duwan, si fiican u qoto dheer, iyadoo la adeegsanayo darajada birta ee kala duwan. Deegaanka daxalka leh
sidoo kale waxay u baahan tahay daboolka laftiisa inuu leeyahay iska caabin daxalka. Xaalada cakiran ee juquraafiga meesha ayaa sidoo kale waydiisay daboolka
isagoo leh waxqabad ka-hortagga burburka.
