A na-ekewa ngwaahịa waya na eriri nke China n'ime ụzọ ise ndị a dịka ojiji ha si dị:
1. waya efu.
2. ikuku ikuku.
3. eriri ọkụ.
4. Nkwurịta okwu cables na nkwurịta okwu fiber optic cables.
5. Ngwa eletriki na waya na eriri.
The isi Ọdịdị nke waya na USB.
1. onye na-eduzi: ihe na-eduzi ugbu a, waya na USB nkọwa na-egosipụta n'usoro nke cross-ngalaba nke onye nduzi.
2. Mkpuchi: ihe mkpuchi nke dị n'èzí dịka ogo nke voltaji na-eguzogide ya.
Na-arụ ọrụ ugbu a na ngụkọta oge.
Igwe ọkụ eletrik (USB) na-arụ ọrụ usoro mgbako ugbu a.
Otu usoro
I=P÷(U ×cosΦ)
P - ike (W);U - voltaji (220V);cosΦ - ihe na-akpata ike (0.8);I - usoro ahịrị ugbu a (A).
Usoro atọ
I=P÷(U×1.732×cosΦ)
P - ike (W);U - voltaji (380V);cosΦ - ihe na-akpata ike (0.8);I - usoro ahịrị ugbu a (A).
N'ozuzu, nchekwa nbibi nke waya ọla kọpa bụ 5-8A/mm2, na nke aluminom waya bụ 3-5A/mm2.
N'ahịrị 220V nke otu oge, ike dị ugbu a kwa 1KW dị ihe dị ka 4-5A, yana na sekit nke atọ nwere ibu ụzọ atọ kwesịrị ekwesị, ikike dị ugbu a kwa 1KW dị ihe dị ka 2A.
Nke ahụ bụ, na sekit otu nkeji, onye ọ bụla na-eduzi ọla kọpa 1 square millimeter nwere ike idi ibu ike 1KW;sekit kwesịrị ekwesị nke atọ nwere ike idi 2-2.5KW nke ike.
Ma dị elu nke na-arụ ọrụ ugbu a nke eriri, nke dị ntakịrị ihe nchebe kwa milimita square nwere ike idi.
