Engineering Overview & Scope
The Positive Power 33/0.415kV industrial step-down transformer provides direct transformation from incoming 33kV utility lines down to 415V industrial utilization voltage. This architecture eliminates the need for an intermediate 11kV switchgear and distribution transformer stage, saving valuable factory floor space and reducing total electrical conversion losses.
Fabricated inside our Gazipur manufacturing plant using high-accuracy CNC automated equipment, the transformer is housed in a heavy-gauge structural steel tank, grit-blasted and coated with epoxy anti-corrosion primer and polyurethane finish to endure high-humidity Bangladeshi industrial environments.
Key Engineering Advantages
- Direct 33kV to 415V transformation reducing capital and substation civil costs
- Low load loss and no-load loss design delivering high energy efficiency
- Heavy-duty structural steel tank with corrugated heat-dissipating cooling fins
- High dielectric mineral oil conforming strictly to IEC 60296 standards
- Bi-directional roller wheels for swift on-site positioning
Primary Industrial Applications
- ▪ Large Composite Garment & Textile Processing Mills
- ▪ Pharmaceutical Production Campuses
- ▪ Export Processing Zones (EPZ) & Economic Zones (BEZA)
- ▪ High-Tonnage Commercial Cold Storages & Warehouses
