FAQ

Questions engineers ask first

Decode the German designation LiYY.

In DIN VDE 0812 nomenclature, 'Li' stands for 'Litze' (fine-stranded flexible copper conductor), the first 'Y' denotes thin-wall semi-rigid PVC core insulation (Type YI2), and the second 'Y' denotes the PVC outer sheath (Type YM2).

How does LiYY differ from YY / YSLY control cable?

LiYY is an electronic signal and data cable built to DIN VDE 0812 in small cross-sections (0.14 to 1.5 mm²) with thin-wall YI2 core insulation and DIN 47100 colour coding (no green-yellow earth core), giving a much smaller outer diameter for D-Sub, M12 and PCB connectors. YY / YSLY is a 300/500 V mains-rated power/control cable (0.5 to 35 mm²) with thicker TI2 insulation and numbered cores.

When should I choose LiYCY or LiHH instead of LiYY?

Select LiYCY when your signal circuit runs near VFD motor cables or switching contactors and requires a tinned-copper braid screen for EMC protection. Select LiHH when the installation is in a public building, airport or rail car requiring low-smoke zero-halogen (LSZH) fire performance.

Can LiYY be used for 230/400 V AC mains power supply?

No. Under DIN VDE 0812, LiYY is rated for 350 V (0.14 mm²) or 500 V (≥ 0.25 mm²) peak operating voltage in low-voltage electronics, signalling, measurement and control circuits, not for heavy mains power distribution.
