In today’s fast-paced construction and energy sectors, project managers and engineers can’t afford to wait months for critical electrical components. At High Power Products (HPP), we recognized early on that traditional lead times—often stretching from 52 to 100 weeks for custom switchgear—were simply too long. By rethinking our entire production pipeline, we’ve been able to deliver many low- to medium-voltage products in half the time our competitors take, all while maintaining the highest standards of safety and reliability.
The Lead Time Challenge in Electrical Equipment
Extended lead times are a growing concern across the electrical industry. Recent analyses show that transformer delivery schedules ballooned from around 50 weeks in 2021 to an average of 120 weeks in 2024, driven by COVID-era disruptions, raw-material shortages, and international shipping bottlenecks, 2024. Likewise, panelboard and switchgear orders routinely faced delays of 20–30 weeks just for protection and metering current transformers alone.
These delays not only slow down site work, but also force constructors to carry higher on-site inventory, raising costs and tying up capital. Clearly, the industry needed a better approach.
Our Three-Pronged Approach
We tackled the lead-time problem head-on with a strategy built around three core pillars:
1. Leveraging Local Resources
Rather than relying on distant suppliers, we partner with regional metal-fabrication shops and parts distributors. This drastically reduces transit time and gives us greater control over raw-material quality and availability. Local sourcing also allows us to respond within days—not weeks—when design tweaks or rush orders arise.
2. In-House Manufacturing
All HPP switchgear and switchboards are built in our own facilities. By vertically integrating fabrication, assembly, and final testing, we eliminate handoffs that can introduce delays or errors. Our teams follow standardized work instructions and utilize specialized jigs and fixtures to streamline each build. This in-house approach enables rapid changeovers and consistent throughput.
3. Strategic OEM Partnerships
While HPP is an original equipment manufacturer (OEM) of switchgear assemblies, we source critical subcomponents from every major global OEM—ensuring both performance and interoperability. By maintaining authorized relationships with leading breaker, relay, and bushing manufacturers, we secure priority access to high-quality parts. This hybrid model lets us remain nimble while still offering best-in-class electrical protection and switching products.
Embracing Lean Manufacturing and Advanced Planning
Beyond our core structure, we’ve adopted proven lean-manufacturing methods—such as value-stream mapping and single-minute exchange of die (SMED)—to drive further efficiency. For example, by applying SMED principles originally developed by Toyota, we reduced equipment setup times from hours to under 15 minutes, cutting queue delays and allowing lot-sizes of one.
Additionally, our advanced planning and scheduling software forecasts material needs weeks in advance, flags potential bottlenecks, and optimizes assembly sequences. This digital layer ensures that every work order flows smoothly through cutting, fabrication, assembly, and testing—with minimal wait times. As one case study showed, a similar approach in transformer component production yielded a 52.9% reduction in process lead time and an 80.7% drop in processing time.
Ensuring Quality at Every Stage
Speed is meaningless without reliability. Our quality-assurance program combines:
- Incoming Inspection: Every batch of raw material and OEM part undergoes dimensional and electrical testing to verify specifications.
- In-Process Audits: Trained inspectors oversee key steps in fabrication and assembly, immediately addressing any deviations.
- Final Acceptance Testing: Each finished unit is bench-tested under simulated load conditions and subjected to dielectric, insulation-resistance, and functional tests.
By embedding quality checks throughout the process, we catch issues early—before they can cascade into rework or field failures.
Delivering Custom Solutions with Rapid Turnaround
Because every project is unique, we maintain a flexible “custom-engineer” team that can adapt designs within hours. Whether you need an unusual voltage rating, special enclosure, or integrated metering package, our engineers leverage modular design libraries and 3D-CAD templates to generate shop drawings in less than a day. Meanwhile, our local supply chain kicks into action to procure any specialized components. The result: a bespoke solution delivered faster than a typical “off-the-shelf” offering.
Conclusion & Call to Action
Through local partnerships, in-house manufacturing, strategic OEM sourcing, lean practices, and digital planning, we’ve slashed typical industry lead times by more than 50%—all without compromising on safety or performance. If you’re planning a project and need switchgear, switchboards, delivered on your schedule, let HPP be your trusted partner.
