Paired Armoured Instrumentation Cable is widely used for reliable signal transmission and control systems in harsh industrial environments. Designed in accordance with EN 50288-7, this cable ensures stable performance in applications where accuracy, safety, and resistance to interference are critical.
This XLPE insulated, overall screened SWA PVC instrumentation cable is ideal for use in oil & gas, petrochemical plants, refineries, power generation, and industrial automation systems. The overall screen (Aluminium/Polyester tape with tinned copper drain wire) provides excellent protection against electromagnetic interference (EMI), ensuring clear and uninterrupted signal transmission.
Thanks to its steel wire armour (SWA), the cable is suitable for direct burial, outdoor installations, and areas exposed to mechanical stress. The PVC outer sheath with oil-resistant properties makes it highly suitable for hazardous and corrosive environments, including offshore and chemical industries.
Typical applications include:
This armoured screened instrumentation cable is engineered for low-voltage signal circuits (e.g., 4–20 mA), delivering high performance, durability, and long service life in demanding conditions.
This structure is not a single-function design, but a “multi-layer protection system”:
This cable is selected because it provides excellent EMI protection, superior mechanical strength, and reliable signal transmission in harsh industrial environments such as oil, gas, and power plants.
The construction of this paired armoured instrumentation cable is designed to ensure reliable signal transmission, mechanical protection, and resistance to harsh industrial conditions:
1. Conductor
Stranded bare copper conductors (Class 2) for good conductivity and flexibility.
2. Insulation
Each conductor is insulated with XLPE (Cross-Linked Polyethylene), providing excellent thermal performance, electrical insulation, and durability (up to 90°C).
3. Pairing (Twisting)
Two insulated conductors are twisted together to form a pair, which helps reduce electromagnetic interference and crosstalk.
4. Overall Screening (OS)
An overall screen consisting of Aluminium/Polyester (Al/PET) tape with a tinned copper drain wire is applied to protect against external EMI and ensure signal integrity.
5. Inner Sheath (Bedding)
A PVC inner sheath is applied over the screened pairs to provide a smooth bedding layer for the armour.
6. Armour (SWA)
Galvanized Steel Wire Armour (SWA) provides strong mechanical protection, making the cable suitable for direct burial and industrial installations.
7. Outer Sheath
A PVC outer sheath (black, oil-resistant) protects the cable from environmental factors such as moisture, chemicals, and abrasion.
This cable is typically designed and tested in accordance with:

Q1: What is the advantage of the paired design in instrumentation cables?
The paired design helps to minimize electromagnetic interference and crosstalk between signal circuits. By twisting two conductors together, the cable improves signal balance and ensures more stable and accurate transmission, which is essential for PLC and DCS systems.
Q2: Why is overall screening important in this type of cable?
The overall screen provides a continuous barrier against external electromagnetic noise. It protects low-level instrumentation signals from interference caused by nearby power cables, motors, and industrial equipment, ensuring reliable data transmission in noisy environments.
Q3: Can SWA armoured instrumentation cables be directly buried?
Yes, cables with Steel Wire Armour (SWA) are designed for direct burial applications. The armour layer provides excellent mechanical protection against crushing, impact, and rodent damage, making it suitable for underground installation and harsh industrial conditions.
Q4: What is the difference between paired and multicore instrumentation cables?
Paired instrumentation cables consist of two conductors twisted together, which reduces crosstalk and improves signal accuracy. Multicore cables contain multiple individual cores and are typically used for higher circuit density but may have slightly higher signal interference.
Q5:Can you provide free sampes?
Yes, samples are free, you just need to pay the shipping cost.
