Low-Voltage Engineering, Assembly and Testing Under One Roof

Lead time on a low-voltage assembly is driven by three things: the complexity of the design, the availability of the selected components, and the build and test capacity at the time of order. We give an indicative lead time with every proposal and confirm it at order, so it can be built into your programme with confidence rather than treated as an unknown. Where a project is phased, we can sequence deliveries to match the construction schedule rather than shipping everything at once.

Because we standardise on ABB ranges and, for multi-board projects, on repeatable standardised designs, procurement and build are more predictable than they would be with bespoke one-off assemblies sourced from mixed suppliers. Packing is specified for the transport and storage conditions the assembly will face, and we coordinate dispatch and site delivery so the equipment arrives ready to install. After-sales support and spare-part guidance continue once the assembly is in service.

Different stakeholders need different things from a panel builder, and our process is shaped to serve all of them. EPC contractors value a single accountable supplier who delivers compliant assemblies on programme, with documentation that supports inspection and handover. Consultants want confidence that the as-built equipment matches the specification they wrote, and the freedom to engage early on configuration and form of separation. Facility owners care most about the years after handover: reliable operation, available spares, and clear records when something has to be maintained or modified.

Because we engage at any of these points, we can advise a consultant at the specification stage, take a contractor’s enquiry straight to a technical proposal, or support an owner with after-sales guidance on equipment already in service. The common thread is the same disciplined engineering, the same authorized ABB systems and the same IEC 61439 verification, applied to whatever stage of the project you bring to us. That consistency means the relationship can carry across multiple projects and across the full life of the equipment, rather than ending at a single transaction.

Compliance is not an afterthought at Exa Power. Our assemblies are engineered to IEC 61439 from the outset, with verification by the methods set out in the standard. We maintain the design and routine-test records that support each build, and these are available on request. Where a project requires it, witnessed factory acceptance testing can be arranged so your team can confirm performance before dispatch.

By standardising on ABB systems, we benefit from manufacturer-validated designs and consistent component performance, which translates into predictable behaviour, easier maintenance and reliable spare-part availability over the equipment’s life. The combination of a type-tested system and disciplined routine verification is what allows us to stand behind every assembly we deliver, from a single distribution board to a large multi-section switchboard.
