(l)Average temperature of operating environment more than 35℃, or fairly large load, choose YJV type branch calbe with XLPE insulatorand PVC sheath.
(2)Ordinary working situation, choose the "VV" type branch cable with poly thene insulator and PVC sheath.
(3)Distribution circuit with fire-resistan design requirements can shoose ZR-the fire resistant branch cable.
(4)Circuits for fire equipment, emergency illumination etc. should choose NH flame resistant branch cable.
(5)Impotrant construciton site and densely inhabited district should choose DL or WL branch cable (cleaning type branch cable).
(6)Gross section of the main cable and the branch chosen should meet the requirements of voltage drop and should be remained 30% capacity in advance.
