Control Cables Manufacturers

Industrial Cable Range We Manufacture

Our Industrial Cables family is built around fixed and flexible installations inside factories, substations, water treatment plants, machine tools and process skids. Each construction is defined by voltage level, insulation material, shielding type, core count and sheath compound, so the same conductor size can be supplied in several performance grades.

Application Fit Across Industrial Systems

Industrial cable selection starts with the signal or power duty, then moves to the environment. A cable that carries 4–20mA from a pressure transmitter has different shielding and capacitance requirements from a 61-core interlock cable in a motor control centre. We match the construction to the loop rather than supplying one generic type for every panel.

• Process automation: instrument cables between field sensors, junction boxes and DCS/PLC cabinets.
• Motor control: XLPE or PVC control cables for contactor, relay and indication circuits.
• Drives and inverters: 1kV variable frequency power cables with low transfer impedance.
• High-temperature zones: silicone or fluoroplastic insulated computer and instrument cables rated to 180°C or 200°C conductor temperature.
• Outdoor and buried routes: armoured or UV-resistant sheathed control cables for cable trenches and direct burial.

Construction Options and Critical Specifications

Every Industrial Cable we quote is defined by a construction table. The table below summarises the main variables we confirm before production, using the standard configurations published for our control and instrument ranges.

Signal Integrity and Shielding Design

For instrumentation and computer cables, shielding is the difference between a stable reading and a fluctuating one. We build foil shields for high-frequency noise, braided copper shields where flexibility and mechanical robustness are needed, and composite foil-plus-braid constructions for the most demanding EMC environments. Drain wires are included so the shield can be grounded at the panel end.

Twisted pairs, triads and star-quad groups reduce magnetic pickup. Where power and signal conductors share a cable, we separate them to limit mutual induction. These choices are made at quotation stage, because changing shield type after production is not practical.

Temperature, Installation and Environmental Limits

Rated conductor temperature depends on insulation: PVC, PE and halogen-free polyolefin 70°C; XLPE 90°C; silicone rubber 180°C; fluoroplastic 200°C. Short-circuit allowance for XLPE control cables is 250°C for up to five seconds. Installation temperature should not be below 0°C for standard compounds, or below -20°C for high-and-low-temperature resistant instrument cables.

• Bending radius: 6× outer diameter for flexible or non-armoured braided cables; 8× for unarmoured rigid control cables; 12× for armoured or metal-shielded constructions.
• Routing: separate power and signal cables, maintain tray spacing, and ground shields at one end unless the system design requires otherwise.
• Environment: UV-resistant jackets for outdoor runs, armouring for direct burial, and oil-resistant sheaths for machine-tool interiors.

Quality Control and Acceptance

Henghui Cable operates two production plants and nine workshops with an MES system covering the route from raw material to finished reel. Our quality management, environmental management and occupational health and safety systems are certified, and our solar PV cable range holds TÜV Rheinland, CE and EAC certification. For Industrial Cables, routine factory tests cover conductor resistance, insulation resistance, high-voltage withstand and dimensional checks; fire-resistant and halogen-free grades are verified against the relevant performance requirements.

Acceptance documentation can include test reports, certificate of conformity and reel-length records. Where a project specifies third-party inspection or witness testing, we coordinate the inspection schedule with the customer's representative before shipment.

Related Cable Families for Complete Projects

Industrial Cables often sit alongside other circuits in the same plant. We supply the full set so that insulation systems, sheath compounds and documentation remain consistent across the project.

• Power Grid Transmission & Transformation Cables — 1.8–3kV, 6–35kV and 66–110kV XLPE power cables for substation and feeder connections.
• Rail & Transit Cables — halogen-free, low-smoke constructions for tunnels, stations and rolling stock.
• Infrastructure & Construction Cables — fixed wiring, PVC insulated wires and cords for buildings and plants.
• New Energy Cables — solar photovoltaic cables and related DC cables for generation and storage systems.

Information We Use to Configure Your Solution

To prepare an accurate Industrial Cables proposal, we need the working point and the installation conditions. The checklist below reflects the data our engineers review before issuing a quotation and production drawing.

• Circuit function: control, signal, instrumentation, drive or power distribution.
• Voltage level: 300/500V, 450/750V or 1kV.
• Conductor size and core count: cross-section in mm² and number of cores, pairs or triads.
• Insulation and sheath material: PVC, PE, XLPE, halogen-free, silicone or fluoroplastic.
• Shielding and armour: foil, braid, composite, steel tape or steel wire.
• Special performance: flame retardant grade, fire resistance, low smoke halogen-free, termite/rodent proof, UV or oil resistance.
• Installation environment: indoor, outdoor, buried, tray, conduit, ambient temperature and chemical exposure.
• Quantity and delivery: total metres, reel length, destination port and required delivery window.
• Documentation: test reports, certificates, packing list and any third-party inspection requirements.

Send these details with your enquiry and we will confirm the model, construction and lead time. Customised cores, colours, lengths and sheath compounds can be produced from drawings or samples.

Frequently Asked Questions

What is the difference between control cables and instrument cables?

Control cables carry switching and interlock signals at 450/750V and are built for mechanical robustness, often with many cores. Instrument cables carry low-level analog or digital signals at 300/500V and prioritise low capacitance, high insulation resistance and effective shielding to protect measurement accuracy.

Can you supply cables for variable frequency drives?

Yes. Our 1kV variable frequency power cable is designed with symmetrical construction and shielding to limit common-mode noise and voltage spikes between inverter and motor. We confirm the drive rating, cable length and routing method before selecting the shield and conductor class.

What temperature range do your Industrial Cables cover?

Standard PVC, PE and halogen-free polyolefin cables are rated to 70°C conductor temperature; XLPE control cables to 90°C. For high-temperature zones we supply silicone rubber insulated cables rated to 180°C and fluoroplastic insulated cables rated to 200°C, with installation temperatures down to -20°C.

Do you produce custom core counts and sheath colours?

We manufacture both standard and customised Industrial Cables. Core counts from 2 to 61, non-standard cross-sections, specific colour sequences, printed legends and alternative sheath compounds can be produced according to customer drawings or samples.

What information is needed for an accurate quotation?

Provide the model or construction, voltage level, conductor size, core count, insulation and sheath material, shielding or armour requirements, special performance needs, quantity, reel length and delivery destination. With these details we confirm the construction and issue a quotation.

How are Industrial Cables packed and delivered?

Cables are supplied on wooden or steel reels with length and drum markings, protected for sea freight. Delivery time for standard Industrial Cables is typically about 7 to 10 days after confirmation, depending on quantity and material availability.
