The HKYFLCY-Bd, HKYFLTCY-Bd, and HKYFLTFY-Bd are a family of Chinese standard (GB/T 6995) screened flexible flat cables designed for elevator control systems, crane festoon cable tracks, and automated production line cable chains. Each designation encodes a specific combination of shielding, conductor type, and application: HKYFLCY-Bd features an overall copper wire braid screen (CY suffix); HKYFLTCY-Bd adds individually screened twisted pairs for signal separation; HKYFLTFY-Bd incorporates a foil screen variant for cost-effective high-frequency shielding.
All variants use fine-wire or extra-fine-wire Class 5/6 copper conductors with PVC insulation and a flexible flat PVC outer sheath. Rated 300/500V; 4 to 40 cores; 0.5 mm² to 2.5 mm²; temperature ‑25°C to +70°C.
| Type | Screening | Best Application |
|---|---|---|
| HKYFLCY-Bd | Overall Cu braid screen | Crane and AGV control in moderate EMI |
| HKYFLTCY-Bd | Individual pair + overall Cu braid | High EMI environments, mixed signal/power |
| HKYFLTFY-Bd | Overall Al-polyester foil screen | Cost-effective HF shielding for data signals |
Select HKYFLCY-Bd for standard crane and AGV control in moderate electromagnetic noise environments. Upgrade to HKYFLTCY-Bd when variable-speed drives or servo systems are present and individual signal pair isolation is needed. Choose HKYFLTFY-Bd as a cost-effective solution where high-frequency (above 100 kHz) shielding is the primary requirement and the lighter foil screen weight is advantageous.
