Connection technology for process technology & steel plants.
We assemble System cabling, braking resistors and Structural assemblies exactly to the requirements of your rolling mill or metallurgical plant — with upfront technical consultation, independent of manufacturer, from a single unit.
01 · Why KnorrTec
Four reasons why KnorrTec is the right partner for your process cabling.
As a cable assembler — not a distributor — we bring the technical expertise that is essential for high-stress connections in steel plants and process facilities. We do not supply off-the-shelf standard goods; instead, we develop the connection that fits your plant.
Technical consultation in advance
Before we begin assembly, we clarify your requirements together — drive power, ambient temperature, cable routing, EMC exposure. This ensures the cabling fits right the first time.
Custom assembly from quantity 1
No minimum order quantity. Exactly your custom length, your connector, your cross-section — from a spare part for an existing plant to equipping a new plant section.
Manufacturer-independent
Compatible with all common drive and control systems. We know the standard connection formats used across the market and supply the right connection — regardless of your plant's manufacturer.
Tested quality
Every assembled cable is 100% electrically tested. Connectors with ingress protection ratings for the harsh everyday conditions of steel plants — with test report on request.
02 · Technical Requirements
What cables in steel plants and process facilities need to deliver.
Standard industrial cables quickly fail near furnaces and rolling mills. Knowing the requirements of a process plant means choosing the right cable material — that is the consulting expertise KnorrTec brings to the table.
High temperature resistance
Proximity to furnaces and rolling mills generates process heat that quickly ages standard sheath materials. We select heat-resistant sheath materials matched to the actual temperature at your plant section.
Large conductor cross-sections
Large drives in rolling mills and metallurgical plants require power cables with correspondingly sized conductor cross-sections. We assemble the appropriate cross-sections including connectors.
EMC shielding
Large drives and induction systems generate strong electromagnetic interference fields. Braided shields with high coverage reliably protect control and signal cables.
Robust mechanical design
Dust, scale, and mechanical stress are the norm in everyday steel plant operations. We assemble with robust sheath materials and connectors that withstand this load.
Long custom lengths
Steel plants and metallurgical facilities often extend over hundreds of meters. We manufacture custom lengths to exactly match your cable routing — with no additional coupling points as a potential source of failure.
Braking resistors for heavy-duty drives
Highly dynamic heavy-duty drives must safely dissipate braking energy. We supply appropriately sized braking resistors together with connection cabling.
"No off-the-shelf cable for your steel plant. Every connection we supply has been discussed with you in advance."
KnorrTec — cable assembler, not a distributor.
03 · Made-to-Measure Assembly
From requirement to finished cable — starting at a single piece.
We are not a catalog supplier. Every cable we deliver was specified together with you and manufactured at our facility in Beratzhausen. That's the difference between a connection that holds — and one that fails.
Inquiry & Consultation
You describe your requirement: plant type, drive power, cable routing, ambient temperature. We ask the right questions — and together we find the optimal cable specification.
Technical specification
Our team specifies conductor cross-section, custom length, shield design, sheath material, connector, and ingress protection rating — documented as a drawing for your records.
Assembly
We manufacture in-house at our own facility — exactly your length, your connector, your print marking. From a single unit to series production, using the same materials and processes.
Testing & Delivery
Every cable is electrically tested. Delivered with a test report — on request with labeling and set packaging for direct installation in your plant.

04 · Applications
Three areas of process technology — one source.
Whether rolling mill and metallurgical plant, process control technology, or heavy-duty drives — we know the specific cable requirements of each area and deliver the right assembly.
B.01
Rolling mills & metallurgical plants
Drive and process cabling for rolling mills and metallurgical plants — heat-resistant, robust, and in the custom length your plant layout requires.
B.02
Process control technology
Sensor and control cabling for the process control level — shielded against interference fields from large drives and induction systems, reliable over long distances.
B.03
Heavy-duty drives
Large drives with high braking energy require more than just a power cable. We supply the complete cabling including braking resistor, matched to your drive design.
05 · Product Categories
The product range for process technology & steel plants.
Drive cables
Power cables for roll drives and large motors — with large conductor cross-sections and heat-resistant sheath materials to your plant specification.
Control & sensor cables
Shielded control and sensor cables for process control technology — from the control cabinet to the field device, immune to interference from large drives.
Custom lengths for large plants
Steel plants often extend over hundreds of meters. We assemble cable sets in exactly the length required, with no additional coupling points.
System cabling
Complete cable sets for process plants — assembled to your drawing, with the connectors and cross-sections your plant requires.
Brake resistors
For heavy-duty drives with high braking energy, we supply appropriately sized braking resistors including the associated connection cabling.
Structural assemblies
Pre-assembled modules for control cabinet construction in process control technology — reduces on-site installation effort and shortens downtime.
06 · Compatibility
Compatible with all common interfaces.
KnorrTec assembles independently of manufacturer — we adapt to the connectors, fieldbus standards, and drive systems already installed in your plant, rather than tying you to a specific brand.
07 · Standards & Certifications
Certified for industrial use.
Every assembled cable for process technology and steel plants is 100% electrically tested. Test reports available on request.
08 · Frequently Asked Questions
To the assembly services for process technology & steel plants.
From what quantity does KnorrTec assemble cables for steel plants?
From a single piece. There is no minimum order quantity. Whether it is a replacement cable for an existing plant, a custom length for a new plant section, or series production for several identical plant components — we manufacture in the quantity you need, with no surcharge for small quantities.
What does "upfront technical consultation" mean in practice for process technology?
Before we begin assembly, we clarify together: What drive power, what conductor cross-section, what cable routing? What ambient temperature and what EMC exposure from large drives or induction systems is present? What ingress protection rating do the connectors require? This conversation ensures that the cabling on first use fits — and does not need to be replaced again after a short time.
How long does custom assembly with special lengths take?
You will receive technical feedback and a quote within 24 hours after your inquiry. Prototypes and smaller batches are typically available in 1–2 weeks . Series production and larger custom lengths are available on request, depending on scope and material availability — we communicate delivery dates transparently and reliably.
What role do braking resistors play in heavy-duty drives?
Heavy-duty drives with high braking energy must be able to safely dissipate this energy during braking — otherwise damage to the drive and inverter can occur. We supply appropriately sized braking resistors including the associated connection cabling, matched to your specific drive design.
For which plant and drive manufacturers does KnorrTec supply compatible connection technology?
We assemble manufacturer-independent for all common drive and control systems in process technology. Since we are not tied to a specific brand, we can also develop suitable solutions for older or less common plant components — simply state the connection standard and requirements in your inquiry.
