Waya netambo mupfungwa yakafara inonziwo tambo.Nenzira yakatetepa, tambo inoreva insulated tambo.Inogona kutsanangurwa semuunganidzwa weimwe kana anopfuura insulated waya cores, pamwe chete neayo akateedzana ekuvhara, yakazara yekudzivirira layer uye yekunze sheath.Iyo tambo inogona zvakare kuve nekuwedzera uninsulated conductors.
Zvigadzirwa zvewaya netambo zveChina zvakakamurwa kuita zvikamu zvishanu zvinotevera maererano nekushandiswa kwavo:
2. waya inomonereka.
4. Tambo dzekukurukurirana netambo dzefiber optic.
5. Zvigadzirwa zvemagetsi zvine waya netambo.
Iyo yakakosha chimiro chewaya netambo.
1. conductor: chinhu chinofambisa ikozvino, tambo uye tambo zvinyorwa zvinoratidzwa maererano ne-cross-section ye conductor.
2. Insulation: iyo yekunze insulation material maererano nedhigirii yayo yekumira voltage.
Kushanda ikozvino uye kuverenga.
Magetsi (tambo) tambo inoshanda ikozvino calculation formula.
Single-phase
I=P÷(U×cosΦ)
P - simba (W);U - voltage (220V);cosΦ - simba chinhu (0.8);I - chikamu mutsara ikozvino (A).
Nhatu-chikamu
I=P÷(U×1.732×cosΦ)
P - simba (W);U - voltage (380V);cosΦ - simba chinhu (0.8);I - chikamu mutsara ikozvino (A).
Kazhinji, chiyero chekuchengetedzwa kwetambo yemhangura ndeye 5-8A/mm2, uye iyo yealuminium waya ndeye 3-5A/mm2.
Mune imwe-chikamu 220V mutsara, ikozvino pa1KW simba inosvika 4-5A, uye muchikamu chetatu-chikamu chine chiyero chetatu-chikamu mutoro, ikozvino pa1KW simba rinenge 2A.
Izvi zvinoreva kuti, mune imwe-chikamu chedunhu, imwe neimwe 1 square millimeter yemhangura conductor inogona kumira 1KW simba rekutakura;chetatu-chikamu chakaenzana chedunhu chinogona kumira 2-2.5KW yesimba.
Asi iyo yakakwirira kushanda ikozvino kwetambo, idiki yakachengeteka ikozvino pa square millimeter inogona kumira.
