INSTRUMENTATION CABLES FAQs
Click a question to reveal the answer.
How do Chinese (GB) and International naming conventions for instrumentation cables differ?
In the international market, naming conventions follow structural codes defined by standards like BS 5308, EN 50288-7, or UL 13. The Chinese system utilizes the GB (Guobiao) standard based on Pinyin initials.
-
Chinese System (GB/T): Common models include DJYVP (Polyethylene insulation, PVC sheath, braided shield), DJYPVP (Individual and collective shield), and DJYPVRP (Flexible version). The "DJ" prefix denotes instrumentation/computer use.
-
International System: Focuses on standard-specific codes such as RE-2X(st)Y (XLPE insulation, static shield, PVC sheath), CU/TICW/OS/LSZH (Copper/Tinned Copper/Overall Shield/LSZH), or PLTC (Power Limited Tray Cable).
Common Models Comparison:
| Application | Chinese Model (GB) | International Model (EN/BS/UL) |
| Overall Shielded | DJYVP / DJVVP | RE-2Y(st)Y / BS 5308 Part 1 Type 1 |
| Individual & Overall Shield | DJYPVP | RE-2X(st)H PiMF / BS 5308 Part 2 Type 2 |
| Armored (SWA/SWB) | DJYVP22 | RE-2Y(st)Y SWA / UL 13 PLTC |
Compatibility is driven by technical parameter alignment. While codes like DJYPVP and RE-2X(st)Y appear different, they are both manufactured to meet IEC 60332 (flame retardancy), IEC 60228 (conductor resistance), and IEC 60079 (explosive atmospheres). As long as the core cross-section (mm² or AWG), insulation material (PE, XLPE, or PVC), and shielding effectiveness match the project’s engineering blueprints, the cables are functionally interchangeable and safe for global integration.
-
Overall Shield (OS): A single layer of aluminum foil or tinned copper braid wraps all pairs. It protects the signal from external electromagnetic interference (EMI).
-
Individual Shield (IS): Each pair is wrapped in its own foil. This is critical for preventing crosstalk (interference between adjacent signals) in multi-pair cables.
-
Combination (IS/OS): Cables with both provide the highest signal integrity, essential for sensitive analog data in petrochemical or power plants.
-
XLPE (Cross-linked Polyethylene): Offers superior thermal stability (up to 90°C), lower dielectric constant, and better moisture resistance. It is the preferred choice for long-distance signal transmission where signal attenuation must be minimized.
-
PE (Polyethylene): Excellent for high-frequency signal transmission but has lower temperature limits.
-
PVC: Cost-effective and flexible, but typically limited to 70°C and less suitable for critical high-speed data.
In the event of a fire, LSZH cables do not release toxic halogens or dense black smoke. This is mandatory in the international market for confined spaces, offshore platforms, and control rooms to protect both personnel and sensitive electronic equipment from acid gas corrosion.
In hazardous areas (ATEX/IECEx zones), intrinsically safe cables are used to limit electrical energy to prevent sparks that could ignite explosive gases. These cables are typically distinguished by a Light Blue outer jacket to alert technicians that the circuit is low-energy.
-
Steel Wire Armor (SWA): Provides maximum crush resistance and longitudinal strength. Ideal for direct burial or high-traffic industrial zones.
-
Steel Wire Braid (SWB): Offers mechanical protection while maintaining high flexibility. Better suited for installations with tight bends or vibration.
Most international specifications require Class 2 (Stranded) or Class 5 (Flexible) tinned copper conductors. Stranded conductors prevent the "skin effect" and provide the durability needed for terminal connections in vibrating industrial environments.
Choosing the right support system depends on the cable load and environmental stressors:
-
Perforated Cable Trays: Provide excellent ventilation and are the standard for most instrumentation runs.
-
Wire Mesh Cable Trays: Best for light-duty cables and data centers where flexibility in routing and cleanability are priorities.
-
Cable Ladders: Used for heavy, large-diameter armored cables requiring maximum support and heat dissipation.
-
Solid Bottom Trunking: Protects sensitive signals from physical damage and provides extra EMI shielding in high-noise areas.
According to international standards like IEEE 518, instrumentation cables should be separated from power cables to prevent induction noise. If they must share a space, use a Cable Tray with a Divider or maintain a minimum clearance (usually 300mm–600mm) depending on the voltage of the power lines.
EMT provides a rigid, grounded metallic barrier that offers superior protection against physical impact and high-frequency interference. It is commonly used in commercial and light industrial zones where cables must transition from open trays to wall-mounted equipment.
The drain wire (usually tinned copper) remains in constant contact with the aluminum foil shield. It provides an easy path for grounding induced currents at the termination point, ensuring the shield remains effective across the entire cable length.
-
Pairs: Standard for most 4-20mA analog loops.
-
Triples: Required for RTD (Resistance Temperature Detector) circuits to compensate for lead-wire resistance.
-
Quads: Used in specific digital communication protocols or to reduce the overall diameter in high-density installations.
For unarmored instrumentation cables, the radius is typically 7.5x to 10x the Outer Diameter (OD). For armored cables (SWA), it increases to 12x to 15x the OD. Exceeding these limits can fracture the aluminum foil shield or damage the core insulation.
To ensure Electromagnetic Compatibility (EMC), shielding should ideally be grounded at only one end (usually the control room end) to prevent "ground loops," which can introduce the very noise the shield was intended to block. Use specialized EMC Cable Glands when entering metallic enclosures.
