ÖLFLEX® EB CY — экранированный кабель управления для искробезопасных цепей type of protection “i”
ÖLFLEX® EB CY combines the sky-blue intrinsic-safety identification of EB cables with CY shielding. The tinned-copper braid protects signal transmission within intrinsically safe circuits against electromagnetic interference, while the sky blue PVC outer sheath similar to RAL 5015 supports clear visual assignment to type of protection “i” circuits.
The cable is designed without inner sheath and uses plastic foil wrapping under the screen. This makes the structure compact while retaining shielding performance, UV/weather resistance according to ISO 4892-2, 300/500 V nominal voltage and defined electrical parameters for intrinsic safety assessment.
1. Product positioning: intrinsic safety plus EMC screening
ÖLFLEX EB CY should be positioned as the screened version of the EB intrinsic safety control cable. It is intended for intrinsically safe circuits where EMC protection is also required. The key selling point is the combination of type “i” circuit identification, sky blue sheath and tinned-copper braid screening.
