What are instrumentation cables?
Instrumentation Cables: The "Nervous System" of Industrial Automation, Dingzun Cable Leads with 20-Year Expertise
As global industrial automation accelerates, instrumentation cables—dubbed the "nervous system" of modern factories—are gaining unprecedented attention. These specialized cables transmit low-energy analog and digital signals for monitoring and control, which are critical to industries such as oil & gas, petrochemicals, and steel.
Unlike standard power cables, instrumentation cables require a robust anti-interference design to ensure stable signal transmission. Their core structural advantages lie in specialized protective components:
| Cable Part | Description and details |
| Conductor Material | Copper or Tinned Copper mainly |
| Cl=Fire Barrier | MGT(Mica glass tape) optional when it requires fire performance |
| Insulation Material | Y(PVC), 2X(XLPE), 3G(EPR) and etc. |
|
IS=Individual Shield PIMF, TIMF, QIMF, ICAM |
Main type AL-PET and drainwire TC for each twisted pair/triad/quad, optional when it is required |
| Cores/Pairs | Multi cores stranded; multi pairs, multi triads and multi quads twisted |
| OS=Overall or Collective Shield(ST) (OSCR)(CAM) | Main type AL-PET and drainwire TC for overall parts usually it is required |
| Inner Jacket or Sheath | Y(PVC), H(LSZH) and etc. , optional when it is required |
| Armor Layer | SWA(galvanized steel wire armored wrapping) mainly, optional when it is required |
| Outer Jacket or Sheath | Y(PVC), H(LSZH), Y-fl(Flame retardant PVC) and etc. |
| Rating Voltage |
300 V for single or multi pairs/triads/quads instrumentataion cables 300/500 V for single or multi cores instrumentataion cables others are supported |
| Basic Standard | EN 50288-7 |
they are equipped with shielding layers (often made of aluminum foil or copper wire braiding) to block external electromagnetic interference (EMI), and wrapped in durable sheaths made from materials like PVC, XLPE, or LSZH. These structural and material choices not only enhance the cables’ resistance to electromagnetic disruption but also enable them to withstand harsh environmental factors such as extreme temperatures, moisture, and corrosion.
The unique performance of instrumentation cables makes them indispensable in high-demand industrial scenarios. For example, in oil refineries—where precise monitoring is critical to operational safety—these cables act as a vital link, relaying real-time pressure and temperature data from on-site sensors to central control rooms, directly supporting the prevention of safety hazards and the maintenance of stable production processes. Additionally, their compact structural design offers practical advantages: it saves up to 40% of installation space compared to traditional alternatives, making them particularly suitable for airtight industrial environments (such as closed factory workshops or equipment compartments) where space utilization is a key consideration.
Among manufacturers, Shanghai Dingzun Electric & Cable Co., Ltd. stands out as a national high-tech enterprise with two decades of experience. Founded in 2005, Dingzun integrates R&D, production, and service, offering over 800 cable specifications with an annual output of 70 million meters. Its instrumentation cable lineup includes fire-resistant multi-core models (e.g., 300/500V CU/MGT/XLPE/OS/FR/LSZH/GSWA/LSZH) and explosion-proof variants compliant with EN 50288-7 standards. These products excel in extreme settings—from high-temperature chemical plants to offshore oil rigs.
