Production Processes Of Control cable
Control cables are manufactured via pressure extrusion to lock in PVC density. Quality control goes beyond standard metrics: we conduct mandatory oil resistance and bending tests on each production lot. This verifies actual performance against IEC specs, ensuring durability in real-world automation environments.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: What is the main difference between "Overall Screen" and "Individual & Overall Screen"?
A: An “Overall Screen” only protects the cable from external noise. An “Individual & Overall Screen” (like this product) adds a shield around each pair of wires. This is crucial for preventing crosstalk—where a signal from one pair interferes with another inside the same cable. Use this type when signal precision is critical.
Q: What standards does this instrumentation cable comply with?
A: Our cables are manufactured to comply with BS 5308 (Part 1 & 2), IEC 60502, and GB/T 9330. We can provide detailed datasheets and compliance certificates upon request.
Q: Can I use this cable for outdoor installation?
A: Yes, the UV-resistant PVC sheath allows for outdoor installation in cable trays or conduits. For direct burial or extremely wet environments, please contact us for our SWA (Steel Wire Armored) or specialized PE sheath versions.
Q:What is the voltage rating of this cable?
A: The standard voltage rating is 300/500V. It is designed for low-voltage signal transmission and should not be used for direct power connections to mains electricity.
Q: Why do you recommend PE insulation over PVC insulation for instrumentation cables?
A: PE (Polyethylene) has better electrical properties, specifically lower dielectric constant and lower capacitance. This makes it superior for transmitting high-frequency data signals over long distances with less attenuation compared to PVC insulation.
Q: Do you offer armored versions for mechanical protection?
A: Yes, we offer SWA (Steel Wire Armored) or Double Steel Tape Armored options. These provide extra protection against crushing, rodent damage, and physical impact, making them ideal for direct burial.
Q: How are the pairs identified?
A: Pairs are typically identified by color coding (e.g., Black/White) with numbered referencing on the core, or by standard color charts (ANSI/ICEA or BS standards). We can customize the color coding to match your project requirements.
Q : What is your MOQ (Minimum Order Quantity) and lead time?
A: Our standard MOQ is typically 500-1000 meters depending on the specific size and core count. Lead times are generally 10-15 days for production. Please contact our sales team for stock availability on common sizes like 1-pair or 2-pair cables.
