Not covered here? Send your drawing — an engineer replies within 2 business hours.

What governing standard and construction define FL11Y (FL11Y (ISO 6722) Abrasion-Resistant TPE-U (PUR) Automotive Low-Voltage Primary Wire)?

FL11Y (FL11Y (ISO 6722) Abrasion-Resistant TPE-U (PUR) Automotive Low-Voltage Primary Wire) is manufactured in accordance with ISO 6722-1 Class C / DIN 72551 for 60 V DC (600 V peak) service over -40 °C to +125 °C. Its 2-layer construction comprises stranded copper conductor, tpe-u insulation.

What is the minimum bending radius and installation temperature for FL11Y?

The minimum installed bending radius for FL11Y is 5 × OD across its continuous operating temperature range of -40 °C to +125 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of FL11Y arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per ISO 6722-1 Class C / DIN 72551); (02) TPE-U insulation (Extruded TPE-U insulation dielectric (continuous layer)).

What factory test certificates are supplied with FL11Y?

Every production drum or spool of FL11Y undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per ISO 6722-1 Class C / DIN 72551, and is delivered with an EN 10204 3.1 factory test certificate.
