FAQ

Questions engineers ask first

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

Why choose screened KYFLCY over unscreened KYFLY in crane festoon systems?

KYFLCY incorporates a 70–80 % coverage copper braid screen around the cores or bundles. When terminated 360° at the VFD cabinet and motor terminal box, it suppresses high-frequency common-mode noise from PWM inverter drives and prevents interference with adjacent encoder or fieldbus cables.

What is the voltage rating difference between control and power sizes in KYFLCY?

Control and signal cross-sections up to 1.0 mm² are rated 300/500 V (2.0 kV test voltage), whereas 1.5 mm² to 95 mm² crane power and control sizes are rated 450/750 V (2.5 kV test voltage).

How should the copper EMC screen be terminated at the crane trolley and junction box?

Use flat EMC cable glands or 360° metallic screen clamp bars at both ends to bond the copper braid directly to the earthed enclosure backplate; avoid long 'pigtail' screen leads which increase high-frequency impedance.

When should I specify KYFLTFCY instead of KYFLCY?

KYFLCY is self-supporting up to 35 m hanging length via its copper conductors (15 N/mm² limit). For vertical hoist drops or high-bay stacker loops from 35 m up to 80 m, specify KYFLTFCY with integrated strain-bearing suspension elements.
