What can you expect?

Immediate availability

No lengthy onboarding processes. As a specialist with a background at SPIE and SBI Connectors, I quickly understand the context of high-voltage projects.

Flexible availability

From a one-off review to full-time — depending on the scope of the assignment. On-site, remote or hybrid, by arrangement.

Standards-driven approach

Familiar with IEC 60865, IEC 61284, IEC 62271 and EN 50341. Your output meets the applicable frameworks.

Independent judgment

No supplier interest, no agenda. You get the judgment that the engineering requires.

On-site execution guidance

During the actual mounting, I can also guide your team on site — from clamp selection to correct execution according to the supplier's standards.

How does Nexums work?

Nexums follows a fixed six-step approach:

  1. Connection advice & selection — Nexums advises on the right type of connection for your situation, taking account of load, environment and standards.
  2. Collaboration with engineering — Nexums works closely with internal and external engineering teams to integrate connection details into design, revision and execution.
  3. Second opinion — In case of doubt about an existing design or execution, Nexums provides an independent, substantiated and verifiable technical assessment.
  4. Technical documentation — Nexums prepares assembly specifications, inspection reports and connection drawings that comply with the applicable standards (IEC, NEN and grid-operator requirements).
  5. Inspection & diagnosis — On site, Nexums assesses the condition of connections through visual inspection and measurement data, with clear reporting on risks and priorities.
  6. Knowledge transfer — Through on-site guidance or targeted sessions, Nexums transfers knowledge to your team, so that quality is also safeguarded internally.
Who does Nexums collaborate with?

Nexums regularly consults SBI, which holds a significant share of the Dutch high-voltage clamp market. Because a large proportion of the clamps used in the Dutch high-voltage sector come from SBI, this is a practical way to obtain up-to-date product information. Nexums' assessments and recommendations remain fully independent throughout: based on IEC/EN standards and the technical situation, not on commercial interest or product preference.

Which standards does Nexums use?

Nexums assesses against IEC 60865, IEC 61284, IEC 62271, EN 50341 and related international standards.
