Export Markets & Country Compatibility
The Low-Voltage Draw-Out Switchgear is provided to distribution and industrial projects in Southeast Asia, the Middle East, Africa, Latin America and South Asia. The panels are designed according to the voltage, frequency and protection requirements of the receiving country, with certification confirmed on a case-by-case basis.
Panel Dimensions, Weight & Packing
The dimension and the weight of the panel depend on its configuration and rated current. LV cabinets are generally 600-1000 mm wide, 600-1000 mm deep, and 1800-2200 mm high approximately, while the size of MV panels depends on their switchgear design. The final versions of dimensions and weights will be included in the approval drawings, and it will be emphasized that the panels are packed vertically before transportation.
- Approval drawings indicate the dimensions and the weight.
- Panels are packed vertically with the busbar protection.
- Lifting and transportation arrangements are agreed based on the order requirements.
