FLRY-B wire are single-core cables specifically designed for vehicle electrical systems, setting the standards in the automotive sector. The FLRY-B wire stands out particularly for its thin-wall PVC insulation and its structure that does not lose flexibility over a wide temperature range, from -40°C to +105°C. This cable, which provides vital power and signal transmission from the engine compartment to the interior cabin of a car, must be resistant to fuels, oil, and abrasion. Produced by global leaders like Prysmian Group, this special conductor is the automotive equivalent of reliability and long-term investment.
In this guide, we will examine the fundamental differences between FLRY-B wire and FLRY-A, why these cables are as critical as a high voltage cable, and how Deltatema provides expert solutions for your projects.
Technical Structure and Decoding of the FLRY Cable Series
The FLRY series is manufactured according to international standards such as DIN 72551 and ISO 6722. The coding indicates the insulation type and flexibility of the cable:
- FL: Thin Wall Insulation. This is critical for complex wiring layouts in confined spaces and where space-saving is required.
- R: Round Conductor.
- Y: PVC (Polyvinyl Chloride) Outer Sheath.
- -A / -B: Indicates the conductor stranding structure:
- FLRY-A: Unilay stranding structure (concentric layers).
- FLRY-B wire (Bunched): Has a bunched structure. With a higher number of thinner strands, FLRY-B typically offers greater flexibility than FLRY-A.
The Role of Thermal and Chemical Resistance in Automotive
The success of the FLRY-B wire lies in its unique resistance to temperature and chemicals:
- Temperature Resistance: Capable of continuous operation over a wide temperature range from -40°C to +105°C. A critical feature for the engine compartment.
- Chemical Resistance: Resistant to fuels, oils, acids, and moisture. This ensures the cable installation maintains its function even in case of leaks or spills.
- Abrasion and Vibration: Offers mechanical resistance against constant vibration and friction between cable harnesses that occurs when the vehicle is in motion.
FLRY-B Wire: High Performance in Critical Systems
Although the FLRY-B wire series is used for low voltage systems (like 12V/24V), its role in automotive is as critical as a high voltage cable.
- System Integrity: A small failure in an FLRY cable can lead to sensor errors, disruption of the engine control system, or even vehicle failure. In electric and hybrid vehicles, these cables are used in crucial points requiring high temperature resistance.
- Critical Applications: Lighting, signaling, instrument panel circuits, and engine control systems. These cables must transmit low-voltage signals stably.
The role of the FLRY-B wire in the vehicle’s control and safety systems is just as important as the role of the high voltage cable in the power grid.
