Electrical design

Everything that carries power — from the substation that feeds a site down to the sockets in a room. This is our largest area of work.

Overview

Electrical design

We deliver premium HT, LT and ELV electrical engineering solutions for AIS (Air Insulated Substation) and GIS (Gas Insulated Substation), industrial plants, commercial developments and infrastructure projects — executed in strict accordance with IEC, IS, NBC and local electrical authority standards.

Our integrated approach ensures safety, efficiency, reliability and long-term performance across the complete project lifecycle.

LT work covers residential, commercial and industrial installations. HT work covers GIS and AIS substations.

What we design

Electrical scope
Steel gantry structures, busbars and isolators in an outdoor high-voltage switchyard.
Gantry structures, busbars and isolators in an outdoor switchyard
  • Substations and transmission lines, 11 kV up to 220 kV
  • Substation layout and equipment sizing
  • Transformer, DG set, UPS and stabiliser calculation
  • Earthing and lightning protection
  • Protection, metering and relay settings
  • Cable sizing, routing and schedules
  • Internal and external electrification — wiring, cabling and lighting
  • Low-voltage distribution for homes, offices and factories
  • Motor control for industrial plant
  • Solar PV and power plant electrical
  • Fire alarm, CCTV, data and access control
  • Standby power — generators and UPS

Two kinds of substation. An AIS substation sits out in the open air and needs land. A GIS substation is sealed and compact, so it fits where land is expensive — which is why data centres and city sites use them. We design both.
