We providing specialized electrical engineering solutions across Bangladesh. Our team of certified engineers is highly skilled in the design, installation, maintenance, and troubleshooting of sub-stations.

HT Switchgear (ACR/ABS/SF6/VCB/LBS)

HT Switchgear is the main protection and control system for high-voltage electrical networks up to 33KV. We supply, install, and commission various types of switchgear such as ACR, ABS, SF6, VCB, and LBS depending on your project demand. These panels protect the system from short circuits, overload faults, and abnormal voltage conditions. Our service includes proper selection of breaker rating, relay settings, protection coordination, and safe interlocking systems. We ensure reliable operation during switching and fault isolation to protect transformers, cables, and connected loads. We also support cable termination, busbar testing, insulation resistance tests, and commissioning. HT switchgear is essential for industrial plants, commercial buildings, and substation setups where safety and power reliability cannot be compromised. A properly installed HT switchgear system reduces breakdown risks, ensures operational continuity, and improves overall electrical system safety.

Transformer (33KV/11KV/0.415KV)

We provide complete supply and installation for transformers used in 33KV, 11KV, and 0.415KV power distribution. A transformer is responsible for stepping down high voltage to usable low voltage for industrial and commercial loads. Our service includes selecting the right transformer capacity, type, and cooling method based on load demand and future expansion. We perform correct foundation work, earthing, HT/LT cable connection, and installation of protection accessories. We also ensure proper oil level checking, insulation testing, ratio test, and commissioning before energizing. A well-installed transformer ensures stable voltage output, reduces losses, and protects sensitive equipment from voltage fluctuation. We follow standard electrical safety practices, ensuring long-term reliability and minimal maintenance issues. Whether it is for factories, shopping malls, or large building projects, our transformer solutions are built for safe, efficient, and continuous power distribution.

LT Switchgear (ACB/MCCB/MCB)

LT Switchgear is the key low-voltage control and protection system used after the transformer output. We design and install LT switchgear using ACB, MCCB, and MCB to ensure safe power distribution across different areas and loads. This system protects electrical circuits from overload, short circuit, and earth faults. Our service includes proper panel design, load balancing, breaker selection, busbar sizing, and cable arrangement for safe and smooth power flow. We also install protection relays, metering, and indicator systems for monitoring. A quality LT switchgear setup helps prevent unexpected shutdowns, reduces fire hazards, and improves equipment life. It is widely used in industrial plants, commercial buildings, and multi-floor projects where stable power distribution is required. We ensure proper testing and commissioning including IR test, continuity test, and functional verification to deliver a fully reliable and long-lasting LT switchgear solution.

PFI Plant

PFI (Power Factor Improvement) Plant is essential for industries and commercial facilities where heavy electrical loads cause poor power factor. A low power factor leads to higher electricity bills, increased line losses, and penalties from utility providers. We design and install PFI plants to maintain an optimized power factor and improve overall energy efficiency. Our service includes capacitor bank selection, APFC panel installation, auto switching steps, and proper ventilation and safety setup. We ensure accurate sizing based on load profile, operating hours, and real-time power factor condition. A properly installed PFI plant improves voltage stability, reduces unnecessary reactive power consumption, and increases system capacity. It also helps protect transformers and cables from extra heating due to high current flow. We provide complete commissioning and testing to ensure safe operation and long-term reliability. For any factory, production unit, or large commercial building, a PFI plant is a smart investment that saves cost and increases electrical performance.

Metering Unit (HT/LT Meter)

Accurate energy monitoring is critical for cost control and system management. We provide complete installation and setup of metering units for both HT and LT systems. HT metering is used for high-voltage supply monitoring, while LT metering is used for distribution level tracking. Our service includes supply and installation of approved metering devices, correct wiring, sealing arrangements, and proper calibration support. We also ensure safe CT/PT connection for HT metering where required. Metering units allow you to measure real-time electricity consumption, track peak usage, and identify load patterns for cost optimization. For factories and commercial buildings, proper metering helps detect abnormal load behavior, reduces energy wastage, and supports energy audits. We install metering systems with proper protection, accuracy class compliance, and neat panel arrangement for long-term reliability. If you want detailed consumption control, departmental billing, or system performance tracking, a professionally installed metering unit is the right solution.

CT-PT (33/11KV)

CT-PT (Current Transformer and Potential Transformer) systems are essential components in high-voltage measurement and protection. We provide complete CT-PT setup for 33KV and 11KV systems to ensure accurate current and voltage sensing for metering and relay protection. CT measures current flow and PT measures voltage levels, allowing safe monitoring without directly connecting meters to high-voltage lines. Our service includes selecting correct ratio, burden rating, accuracy class, and insulation level for your specific project. We install CT-PT with proper mounting, cable termination, earthing, and protection wiring. CT-PT systems play a major role in fault detection, energy measurement, and safe relay operation. Without correct CT-PT configuration, metering errors and protection failure can occur, causing heavy losses and unsafe operation. We ensure proper commissioning tests, polarity check, ratio verification, and relay integration. For substations and industrial HT systems, our CT-PT solutions ensure safety, compliance, and accurate electrical monitoring.

Sub-Meter Box

Sub-Meter Boxes are used when you want to track electricity consumption separately for different areas, departments, floors, tenants, or machines. We design and install sub-meter systems that provide accurate monitoring and help in cost distribution and energy control. Our sub-meter box solutions include proper breaker protection, safe wiring, meter arrangement, labeling, and easy access for reading and maintenance. This is highly useful in commercial buildings, industries, shopping complexes, and rental properties where separate billing is required. With sub-metering, you can identify high energy-consuming sections, detect power wastage, and plan energy-saving strategies more effectively. We also ensure that the installation follows proper safety rules including correct cable sizing, earthing, and overload protection. A well-designed sub-meter box improves electrical management and reduces disputes in shared energy consumption. If you want proper electricity transparency and better control over your energy usage, a professional sub-meter box installation is an excellent solution.
