Distribution and switchgear
Low voltage and medium voltage systems are designed around current load, future expansion, protection and the need to isolate equipment safely.
4ON CRITICAL INFRASTRUCTURE
Electrical Supply and Installation
4ON designs and installs electrical infrastructure for sites where availability and safe maintenance matter. We cover distribution, transformers, switchgear, protection, monitoring and temporary support.
Transformers
We install and maintain transformers with attention to testing, safe working practices and long term reliability. Maintenance can include visual inspection, oil analysis, tap changer work, insulation testing, partial discharge checks and protection devices.
Continuous breakdown support
Urgent electrical failures can be raised through our support route at any time, with temporary equipment available for some breakdown situations.
Thermal imaging
Infrared inspections can reveal abnormal heating in electrical equipment before it becomes a failure. Our thermography work helps target remedial action and maintenance planning.
Protection coordination
Protection settings and device selection are coordinated so faults are cleared by the correct protective device with the smallest practical impact on the rest of the site.
