Wire le cable ka kutloisiso e pharaletseng li boetse li bitsoa cable.Ka kutloisiso e fokolang, cable e bolela cable e insulated.E ka hlalosoa e le pokello ea li-cores tse le 'ngoe kapa tse ngata tse sirelelitsoeng ka terata, hammoho le likoahelo tsa tsona tse fapaneng, lera le sirelletsang le kantle.Mohala o ka boela oa ba le li-conductors tse ling tse sa sebelisoang.
Lihlahisoa tsa China tsa terata le lithapo li arotsoe ka mekhahlelo e mehlano e latelang ho latela ts'ebeliso ea tsona:
2. terata e tsoelipanang.
4. Lithapo tsa puisano le likhoele tsa puisano tsa fiber optic.
5. Thepa ea motlakase e nang le mohala le mohala.
Sebopeho sa motheo sa mohala le mohala.
1. conductor: ntho e tsamaisang lintlha tsa hona joale, terata le lithapo li hlahisoa ho latela karolo ea sefapano sa conductor.
2. Insulation: thepa ea ka ntle ea ho kenya letsoho ho latela tekanyo ea eona ea ho mamella voltage.
Ho sebetsa hona joale le lipalo.
Motlakase (cable) mokhoa oa ho bala oa hajoale.
Mokhahlelo o le mong
I=P÷(U×cosΦ)
P - matla (W);U - motlakase (220V);cosΦ - ntlha ea matla (0.8);I - phase line current (A).
Mekhahlelo e meraro
I=P÷(U×1.732×cosΦ)
P - matla (W);U - motlakase (380V);cosΦ - ntlha ea matla (0.8);I - phase line current (A).
Ka kakaretso, sekhahla sa ho khaoha ha polokeho ea terata ea koporo ke 5-8A/mm2, 'me ea terata ea aluminium ke 3-5A/mm2.
Moleng o le mong oa 220V, matla a hona joale ka 1KW a ka bang 4-5A, 'me potolohong ea mekhahlelo e meraro e nang le mojaro o leka-lekaneng oa mekhahlelo e meraro, matla a hona joale ka 1KW a ka bang 2A.
Ke ho re, potolohong ea mohato o le mong, e 'ngoe le e' ngoe ea 1 square millimeter ea koporo e ka mamella matla a 1KW;potoloho e leka-lekaneng ea mekhahlelo e meraro e ka mamella 2-2.5KW ea matla.
Empa ha matla a ts'ebetso ea thapo a ntse a phahame, joale motlakase o sireletsehileng ka millimeter e le 'ngoe o ka mamella.
