Shielded, flexible control cable with numbered cores, insulation and PVC sheath with internal reinforcement sheath, outer sheath transparent. Flexible cables intended for operation in power control and protection devices and for control circuits, as well as for supplying electricity to low-power receivers, mobile and portable devices. Thanks to the shielding, the cable is suitable for connections in places exposed to electromagnetic fields, especially in an industrial environment. When the shield is connected on both sides, it meets the requirements of electromagnetic compatibility (EMC). Transparent coating allows optical control of the screen condition. A special filling coating additionally improves the mechanical properties of the cable. Intended for permanent installation and for movable connections in industrial equipment, technological lines, machines operating in dry and damp rooms. The high flexibility of the BIT 500 CY cables facilitates their laying and the insulation materials used allow for easy and quick connection and ensure high durability of the connection.
