  • Tsari Mai Kafa (mm²): Tsari mai kafa na kayan abu

  • Kabilu Masu Shiga: Kayan abubuwa da kamar tsari, ƙarfi, da mutanen kayan abu za su iya amfani da su a cikin kabilu; tsari mai kafa mai daidaito ce sumuwar ƙarfin kabilu

  • Haɗa Barazan (% ko V): Ƙarfin haɗa barazan mai kyau (misali, 3% don lalace, 5% don mawaki)

  • Mutanen Kayan Abubuwa: Tasa (Cu) ko Alusamini (Al), wanda ke taimaka wa ƙarin barazan

  • Nau'in Kabilu:

    • Tsohuwa: 1 kayan abu

    • Biyu na tsohuwa: 2 kayan abubuwa

    • Uku na tsohuwa: 3 kayan abubuwa

    • Nalabi na tsohuwa: 4 kayan abubuwa

    • Dumi na tsohuwa: 5 kayan abubuwa

    • Wasu na tsohuwa: 2 ko da ƙarin kayan abubuwa

  • Yawan Ƙarfi (°C): Baya da nau'in jiki:

    • IEC/CEI: 70°C (PVC), 90°C (XLPE/EPR), 105°C (Jiki Mai Zane)

    • NEC: 60°C (TW, UF), 75°C (RHW, THHN, etc.), 90°C (TBS, XHHW, etc.)

Amsa

  • Ƙarfin ƙarfi mai kyau na kabilu (mita)

  • Haɗa barazan mai yiwuwa (% da V)

  • Barazan kayan abu (Ω/km)

  • Barazan mai kafa (Ω)

  • Malami: IEC 60364, NEC Article 215

An samun wannan don inyinin mai sarrafa da manajan wiring layouts da kuma ƙara ƙarfin barazan mai kyau a cikin abubuwan da ake shiga.
