Area number 03

Electrical Systems

We supply and specify materials, components, protection devices, instrumentation and tooling for electrical systems across low, medium and high voltage. The focus is correct specification — compatibility, voltage class, short-circuit rating, ingress protection and applicable standard — not simply the cheapest catalog item.

The problem

A wrong electrical specification only shows up at energization, or worse, at the first fault. Components with inadequate voltage class, poorly coordinated protection devices and uncertified material reach the site because purchasing worked from a generic description.

Business impact

The cost is not the component: it is the shutdown to replace it, the panel rework, the commissioning delay and the risk to people. Incorrect protection coordination turns a localized fault into a wide outage.

The Noryvex approach

We work from the design documentation — single-line diagram, design memo and bill of materials — and flag divergences before quoting. When the design does not exist or is outdated, we say so instead of quoting blind.

Capabilities

What we do here

Technical scope covered in this area. The exact composition of each project comes from the survey, not from a catalog.

  • Cables, conductors, connectors and terminals
  • Protection and switching devices
  • Instrumentation and electrical measurement
  • Panel and switchboard components
  • Installation materials and electrical infrastructure
  • Technical tooling and auxiliary equipment
  • Low, medium and high voltage applications
  • Substation materials

Scope

What's included

Contractable tracks in this area, on their own or combined. Whatever does not fit your operation stays out of scope — and out of the price.

01

Electrical design and sizing

Load calculation, conductor and protection selection, with a design memo that supports the decision.

02

Substation and medium voltage

Design, assembly and upgrade of the incoming supply, switchroom and transformation.

03

Protection and coordination studies

Short circuit, coordination and arc flash — what decides whether a fault isolates a branch or drops the plant.

04

Power quality

Measurement of harmonics, sags and imbalance, with the source of the disturbance identified.

05

Emergency power

Generator, UPS and automatic transfer sized by the load that genuinely has to keep running.

06

Testing and predictive maintenance

Thermography, relay testing and periodic measurement to find the defect before the unplanned outage.

Industries served

Where this area applies most

Energy & Utilities

Generation, transmission, distribution and sanitation — dispersed assets, high criticality.

Manufacturing

A connected plant floor, with data reaching management without passing through spreadsheets.

Commercial & Corporate

Buildings, offices and complexes: infrastructure, security and building automation.

Data Centers

Technical rooms and mission-critical environments: power, cooling, network and monitoring.

Government

Public bodies: defensible technical specification, traceability and compliance.
