Project Summaries

Keranigonj 230/132 kV GIS Substation This extra‑high‑voltage GIS installation provides compact, reliable switching and protection in a space‑constrained urban setting. GIS technology reduces footprint and improves safety and maintainability.

Rajbari and Rampura 230/132 kV AIS Substations Both AIS projects expand bulk transmission capacity using proven air‑insulated switchgear arrangements that simplify maintenance and allow easier future expansion.

Mirpur DOHS 33/11 kV GIS Substation A distribution‑level GIS substation serving dense residential and commercial loads, designed for minimal land use and high operational reliability.

Gopalgonj 132/33 kV AIS Substation A regional AIS substation that steps down transmission voltage for distribution networks, improving local supply stability and reducing losses.

Technical Highlights

• Mixed technology delivery: Projects include both GIS (Gas‑Insulated Switchgear) and AIS (Air‑Insulated Switchgear) solutions to match site constraints and lifecycle requirements.

• Voltage range: Implementations span 33/11 kV distribution up to 230/132 kV transmission, demonstrating capability across EHV and HV classes.

• Operational benefits: Improved grid reliability, reduced outage durations, and enhanced capacity to meet growing urban and regional demand.

Strategic and Community Impact

• Grid resilience: These substations relieve bottlenecks on key corridors and provide redundancy for critical urban loads.

• Economic support: By increasing transmission and distribution capacity, the projects enable industrial growth and more reliable service for businesses and households.

• Urban planning alignment: GIS installations in dense areas minimize land use and integrate with urban development plans.

Conclusion

BNF Engineers Ltd.’s recent portfolio of GIS and AIS substations across Keranigonj, Rajbari, Rampura, Mirpur DOHS, and Gopalgonj demonstrates the company’s technical breadth in delivering turnkey EHV and HV infrastructure. These projects contribute to a more resilient, efficient, and expandable national grid while addressing both urban space constraints and regional distribution needs.
