4 kV; suitable for LT supplyFrequency: 50 Hz, three-phaseAmbient Conditions: Max temperature +40°C, min -25°C; relative humidity daily ≤95%, monthly ≤90%Installation: Tilt ≤3°, free from frequent severe vibration or corrosive/flammable gasesNotesPreference is given to boxes with insulators fixed on suitable arrangements for bus bars.

All MCC

Bs must be crimped with die-less crimping tools and meet approved clearances. Underground or hybrid boxes may include additional features like waterproofing, submersible operation, and integrated advertising panels for urban installations. These specifications ensure safety, durability, and compliance with Myanmar's electrical standards for commercial, residential, and industrial low-voltage distribution applications.
