OUR DETAILED CAPABILITIES FOR ELECTRICAL

General Plant Layout Engineering

We provide specialized expertise in the planning, design, and drafting of electrical installations tailored to the unique demands of industrial environments—ensuring safe, reliable, and efficient operations across sectors such as Cement, Power, Minerals, and Process Industries.

Substation Equipment Layouts

We provide detailed engineering layouts for 132kV, 220kV, and 400kV AIS substations, fully compliant with IS, IEC, and IEEE standards. Our designs cover equipment layout, earthing, lighting, and cable routing—optimized for safety, constructability, and reliable integration with control and protection systems.

Load center Equipment Layouts

We deliver optimized Load Center Layouts for Electrical Rooms and Substations, ensuring efficient equipment placement—such as Transformers, PCCs, MCCs, APFC Panels, and UPS systems. Designs follow IS/IEC standards with proper clearances for safety, maintenance, and future expansion, while maximizing space utilization and operational efficiency.

Civil Assignment Layouts

We prepare precise civil assignment layouts for Load Canters and Process Buildings to support electrical erection activities. These layouts define equipment foundations, trench routes, embedded conduits, and base frame positions—ensuring seamless coordination between electrical and civil works for efficient, safe, and accurate installation.

Design Criteria Documents

We develop comprehensive Design Criteria Documents covering key aspects of electrical infrastructure, including Cables, Cable Trays, Earthing Systems, Lightning Protection, and Illumination. These documents establish the engineering basis for design, ensuring compliance with IS/IEC/IEEE standards, site-specific conditions, safety requirements, and project specifications.

Design Calculations for HT and LT Cables, Earthing

We carry out detailed design calculations for HT and LT cables and earthing systems, ensuring proper sizing, thermal performance, voltage drop, and fault current withstand capacity. All calculations are aligned with relevant IS/IEC standards, ensuring safe, efficient, and compliant electrical installations.

Cable Tray / Raceway Design

We deliver complete Cable Tray and Raceway Design solutions, ensuring structured, safe, and accessible routing for power, control, and instrumentation cables. Our designs include tray sizing, routing optimization, support span calculation, and segregation planning, all in compliance with IS/IEC standards. Along with detailed Bill of Quantity (BOQ) covering tray accessories, and support materials—enabling accurate procurement and cost estimation.

Earthing & Lightning Protection Design

We provide comprehensive Earthing and Lightning Protection System Design, ensuring safety, reliability, and compliance with IS/IEC standards. Our scope includes system sizing, layout planning, and fault current handling capacity. A detailed Bill of Material (BOM) is included, covering electrodes, conductors, clamps, and accessories for accurate procurement and execution.

Lighting / Illumination Design

We provide detailed Lighting / Illumination Layout Design for industrial and plant facilities, ensuring adequate lux levels, coverage, and compliance with IS/IEC standards. The design is supported by accurate Bill of Quantity (BOQ) including lighting fixtures, poles, cabling, and accessories for efficient procurement and installation.

Cable Scheduling

We prepare detailed Cable Schedules for High Tension (HT), Low Tension (LT), and Control Cables, covering type, size, length, termination, and routing. Integrated with precise raceway details, our schedules ensure organized and efficient cable management. A comprehensive Bill of Quantity (BOQ) is provided, listing cables, Lugs, glands, and accessories for accurate procurement and execution.

Documentation & Compliance

We provide complete Documentation and Compliance support, including detailed design reports, technical datasheets, as-built drawings. All documentation is prepared in strict adherence to IS/IEC/IEEE standards and is tailored to meet client, statutory, and project-specific requirements, ensuring smooth approvals and full audit readiness.

Plant Single Line Diagram

We develop accurate and comprehensive Plant Single Line Diagrams (SLDs) representing the complete electrical distribution system, from incoming supply to the final load points. The SLD includes details of transformers, switchgear, circuit breakers, protective devices, and metering—designed in compliance with IS/IEC standards to ensure clear visualization, safe operation, and effective power system planning.
