Engineering Overview
Holding official ABC Electrical Contractor Enlistment from the Electrical Licensing Board of Bangladesh, Mak Tek Engineering designs, fabricates, assembles, and installs high-reliability electrical distribution switchboards. From 11kV/33kV HT substations to heavy-duty low-tension (LT) main distribution boards, our panels are custom-engineered for maximum operating safety, operational longevity, and intuitive field maintenance.
Custom Switchgear Portfolio
- Main Distribution Boards (MDB): High-amperage (up to 4000A) compartmentalized power distribution panels with draw-out Air Circuit Breakers (ACB) and microprocessor trip units.
- Sub-Distribution Boards (SDB) & DBs: Compact, dust-protected floor-standing and wall-mounted panels for sectional power, utility lighting, and HVAC machinery.
- Motor Control Centers (MCC) & Starter Panels: Star-Delta, Soft-Starter, and Variable Frequency Drive (VFD) panels designed to manage heavy pump motors and compressor loads.
- Power Factor Improvement (PFI) Plants: Microprocessor-governed capacitor banks with detuned harmonic filter reactors to maintain plant power factor above 0.98 and prevent utility penalties.
Craftsmanship & Safety Standards
Every switchgear assembly is housed in 14/16 SWG electro-galvanized cold-rolled sheet steel, chemically treated and electrostatically powder coated in RAL 7035/7032. Busbars are 99.9% pure electrolytic copper sized strictly per international thermal density standards and fully sleeved with color-coded heat-shrink insulation.
