Network Cabling for Manufacturing & Industrial Sites
Shielded cabling for high-EMI environments, OT/IT network separation, fibre backbones, and production-ready infrastructure — installed in live facilities with proper RAMS and coordination with your maintenance and H&S teams.
Manufacturing and industrial network cabling is a specialist discipline. The combination of harsh physical environments, electromagnetic interference from production machinery, live-site working constraints, and the need for proper OT/IT network separation means standard commercial cabling practice is not sufficient. We have delivered network cabling projects in production facilities, chemical plants, food manufacturing sites, precision engineering workshops, and heavy industrial environments across the UK.
If your production monitoring is unreliable, your SCADA communications are intermittent, or your factory network is a mixture of improvised connections and infrastructure that nobody has documented, we can help. We design, install, and certify network cabling infrastructure that is appropriate to the environment and documented to support your IT and OT teams going forward.

The factory floor reality
Industrial Network Challenges We Solve
Electromagnetic interference (EMI) from production machinery
Factory floors are saturated with electromagnetic noise from variable frequency drives (VFDs), large motors, servo systems, induction heating equipment, and welding stations. Standard UTP cabling absorbs this interference, leading to data errors, intermittent link failures, and network instability that is genuinely difficult to diagnose without understanding the production environment. Proper cable specification and routing are the solution.
OT and IT network separation
Production line control systems — PLCs, SCADA platforms, HMIs, and DCS controllers — must be protected from the corporate network. A single ransomware attack reaching the OT network through an unprotected network boundary can halt production entirely. Cyber insurance and manufacturing sector compliance frameworks increasingly require demonstrable network segmentation with documented OT/IT separation.
Harsh physical environments
Manufacturing environments present physical challenges that office cabling is not designed for. Temperature extremes, dust, vibration, moisture, chemical exposure, mechanical impact risk, and pressure washing are all normal conditions on factory floors. Cabling specification, containment, and routing all need to account for these factors from the outset.
Legacy equipment and mixed protocols
Many manufacturing businesses operate equipment with 10, 20, or 30 years of service life. Older machine tools and control systems may use Profibus, DeviceNet, or legacy serial interfaces rather than modern Ethernet. Network infrastructure upgrades need to accommodate this legacy equipment and, where Ethernet connectivity is available, ensure the physical layer supports the communication reliably.
Production uptime and network-dependent processes
Production monitoring, machine status reporting, quality control systems, and ERP integration all depend on continuous network connectivity. A network fault that takes a production cell offline — or silently corrupts process data — has an immediate, quantifiable impact on output. The physical layer must be robust enough to handle the environment, and the design must include appropriate redundancy for critical connections.
Site expansion and future automation investment
Manufacturing businesses investing in automation — new CNC cells, robotic systems, vision inspection, AMRs — need a cabling infrastructure that can absorb this expansion. Properly designed structured cabling with documented outlet schedules and a structured backbone means new equipment can be connected without re-pulling cable or improvising infrastructure.

Technical detail
OT/IT Network Separation: Why It Matters for Manufacturers
Operational technology (OT) — the systems that control and monitor production processes — was historically isolated from corporate IT by design. As manufacturing becomes more connected and data-driven, that isolation has eroded. The result is that many production networks are now directly or indirectly accessible from the corporate network, creating a path for threats to move from office systems to the production floor.
The consequences of a cyber incident reaching OT systems are severe: production line shutdown, equipment damage, safety system compromise, and in some sectors, regulatory breach. The Cyber Essentials framework, NIS Regulations, and increasing requirements from cyber insurers all point in the same direction — OT and IT systems need to be properly separated, with documented controls at the boundary.
At the physical layer, proper OT/IT separation starts with separate cable runs from the start. We install OT and IT network cabling in separate containment where practical, terminate them to separate patch panels in the comms room, and design the physical layout to make it clear which connections are OT and which are IT. This physical separation complements and supports the VLAN-based logical separation that your network equipment team will implement at the active layer.
Why Techcare
Why Manufacturers Choose Us
We understand production environments
We have worked in chemical plants, precision engineering facilities, food production sites, and heavy industrial environments. We understand permit-to-work, isolation procedures, hot-work permits, and the culture of safety that manufacturing businesses rightly maintain.
Correct cable specification from the start
We do not apply office cabling specifications to factory floors. We assess the EMI environment, mechanical risks, and physical conditions in each area of your site and specify the right cable type, containment, and routing for each run.
OT/IT knowledge at design stage
We understand the distinction between OT and IT networks and design the physical cabling to support proper separation — not as an afterthought, but as part of the initial design.
We work around your production schedule
We plan our programme around your planned maintenance windows, shift changes, and production schedule. We do not impose our preferred working pattern on your operation.
Full Fluke certification on every link
Every copper link is Fluke DSX-8000 certified, every fibre run OTDR tested. In production environments where marginal cable performance can cause intermittent production faults, certification is not optional — it is the evidence that your infrastructure meets specification.
ISO 9001 quality management
Our quality management system ensures consistent delivery standards across every project. You receive the same level of documentation, testing rigour, and professional handover regardless of project size.
Common questions
Industrial Cabling FAQs
What cabling do you use in high-EMI environments?
In environments with significant electromagnetic interference — motor drives, VFDs, welding equipment, or heavy electrical machinery nearby — we specify shielded cable (S/FTP or F/FTP) rather than unshielded UTP. The shielded construction suppresses induced noise that would otherwise cause data errors or link instability. We also pay careful attention to cable routing, keeping data cables segregated from power runs and crossings made at 90 degrees where unavoidable.
What is OT/IT network separation and why does it matter?
Operational technology (OT) systems — SCADA, DCS, PLCs, and industrial control systems — should be kept on a logically separate network from corporate IT systems. This separation (typically implemented using VLANs and firewall rules) prevents a cyber incident in the IT environment from reaching production control systems, and prevents operational traffic from competing with business network traffic. It is increasingly required by cyber insurance policies and sector compliance frameworks.
Can you work on a production site during manufacturing hours?
Yes, and most of our industrial projects are delivered in live facilities. We work closely with your maintenance, H&S, and production planning teams to understand permit-to-work requirements, exclusion zones, and the specific constraints of your production environment. Any disruptive activity — cable routes near machinery, network switch cutovers — is scheduled for planned maintenance windows or shift changes.
Do you install cabling for SCADA and production monitoring systems?
Yes. We install the physical cabling infrastructure that supports SCADA, production monitoring, and industrial control system connectivity. The design will incorporate appropriate network segmentation to keep OT traffic on a dedicated, isolated network segment separate from the corporate IT infrastructure.
How do you protect cabling in harsh industrial environments?
We specify and install appropriate mechanical protection for industrial environments — steel conduit or armoured cable in areas with mechanical impact risk, chemical-resistant conduit where process chemicals are present, and high-temperature rated cable in areas near process heat. Cable management is designed with the industrial environment in mind, not just pulled along the most convenient route.
Do you provide cabling for both office and factory floor in the same project?
Yes, and this is common on manufacturing sites where we install Cat6A cabling throughout the site office areas alongside the factory floor infrastructure. The two environments are treated differently in terms of specification and routing, but can be delivered under a single coordinated programme.
