Factory electrical system design & installation
From high-voltage supply and transformers down to the cable into each machine, we handle factory electrical systems end to end, with safety first.
Factory electrical work needs both engineering knowledge and field experience. Our team works with more than 23 skilled technicians, so we can take on anything from small plants to large projects.
We install electrical systems for new factories, production-line expansions, machinery relocations and new electrical rooms, under strict safety procedures at every step.
Industrial electrical installation differs from building work in one key way: it has to fit around the production plan. Every hour a line is down has a cost, so sequencing the work, having materials ready before arriving on site and agreeing the outage window matter as much as the quality of the installation itself.
Before starting, our team inspects the existing system — transformer capacity, cable routes and the condition of the electrical room — to make sure the new work is compatible with what is already there and does not overload upstream equipment.

Factory Electrical Installation
High-voltage systems
HV pole work and incoming supply systems for industrial plants.
Transformer installation
Installing transformers and connecting them to the plant's distribution system.
Low-voltage distribution
Cabling, cable trays and power distribution to machines and buildings.
Machinery relocation
Disconnecting, moving and reconnecting machine power systems in their new position.
New electrical rooms
Design and build of electrical and control rooms, complete with panels and cabling.
Safety first
Strict safety procedures, in the workshop and on site.
Signs your factory's electrical system needs work
Voltage dips when large machines start
Momentary dips can stop or disrupt other machines on the same supply.
New machinery the existing system cannot support
Adding loads without recalculating the total pushes upstream equipment beyond its rating.
Untidy cabling or missing cable trays
As well as risking physical damage, it makes inspection and future extension difficult.
Unusual transformer noise or heat
Load and condition should be checked before a failure causes a long production stoppage.
A cramped or poorly ventilated electrical room
Excess temperature makes protective devices operate inaccurately and shortens their life.
No up-to-date electrical drawings
When drawings do not match reality, maintenance and modifications take far longer.
What to prepare before requesting an installation quotation
- Transformer size and the nature of your current electrical system
- List of machines to be installed, moved or added, with their ratings
- Plant layout and approximate cable routing distances
- When our team can work on site, and when the supply can be switched off
- Your plant's safety requirements and site-entry paperwork
- Photos of the electrical room, installation points and cable routes
A clear process, from site survey to handover
- 01
Consultation & site survey
We review your requirements, electrical loads, installation space and existing systems.
- 02

- 03
Fabrication & assembly
Panels are built in our own workshop by experienced technicians, to the approved design.
- 04
Testing before delivery
Every panel is inspected and function-tested before it leaves our workshop.
- 05
Installation & support
On-site installation, commissioning, handover and ongoing technical support.
Real work from real sites
Frequently asked questions
Do you handle complete electrical systems for new factories?
Yes: system design, transformer installation, MDB and sub-boards, through to cabling for each machine.
Can you relocate machinery including its electrical system?
Yes. We plan the disconnection and reinstallation so your machines are back in production as quickly as possible.
How do you manage safety?
Our team is trained in industrial electrical work and follows strict safety procedures at every step, from workshop fabrication to on-site installation.
How do you handle site safety?
Work requiring isolation follows lockout/tagout procedures with personal protective equipment appropriate to the task, and we comply with the client plant's own safety requirements.
Can you work during shutdowns or weekends?
Yes, and those windows suit outage work best. Tell us your preferred window at quotation stage so manpower and materials can be planned in advance.
What testing is done after installation?
The testing scope is agreed with you at quotation stage. It typically covers checking terminations, insulation resistance measurement and functional testing of the system before handover.
Planning an electrical or control panel project?
Send us your drawings or project details. Our engineers will review them and come back with recommendations and a quotation.
