Nruab nrab voltage fais fab cables muaj ib tug kuj tsawg coefficient ntawm thermal expansion, thiab cable qhov ntev tsis hloov ntau. Qhov no ua kom ntseeg tau tias lub cable yuav tsis cuam tshuam rau kev txhim kho zoo nyob rau hauv cov xwm txheej ntawm thermal expansion thiab contraction, tswj kev sib txuas hluav taws xob zoo, thiab txo qhov kev pheej hmoo ntawm kev tsis ua hauj lwm los ntawm kev hloov kub.
Min. installation kub: 0 degree
Ua haujlwm kub: -25 degree rau +90 degree
Kev khiav hauj lwm kub ceev: 105 degree
Max. Short Circuit kub: 250 degree
Daim ntawv thov
Nruab nrab voltage fais fab cables yuav tsum tau dej-resistant thiab corrosion-resistant, haum rau lub hwj chim kis tau tus mob ntawm generators thiab substations nyob rau hauv hydropower chaw nres tsheb. Cov kab hluav taws xob yuav tsum muaj peev xwm tiv taus cov av noo siab thiab hnyav huab cua hauv cov chaw nres tsheb dej.

FAQ
Q: Cov kab hluav taws xob puas tuaj yeem siv rau hauv thaj chaw marine?
Anti-termite xov hlau yog tshwj xeeb coated los yog ua los ntawm corrosion-resistant hlau (xws li, stainless hlau los yog tooj liab-nickel alloys). Rau ib puag ncig marine, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov cables tshwj xeeb rau cov dej ntsev, feem ntau nrog cov tsho tiv thaiv, uas tiv thaiv UV thiab dej ntsev.
Q: Puas yog nruab nrab voltage fais fab cables haum rau fais fab fais fab?
Q: Cov cables puas yuav tsum tau cim?
Cim npe nrov: Tuam Tshoj anti-termite 19/36kv 3 core aluminium mv hlau, Tuam Tshoj anti-termite 19/36kv 3 core aluminium mv hlau manufacturers, lwm tus neeg, Hoobkas
