Flexibles Kabel 500V OZ-BL-CY 4x2,5 blau für EX-Zonen, geschirmt 14061

Flexible cable for potentially explosive atmospheres

This blue, shielded OZ-BL-CY 4x2.5 cable with a voltage of 500V is a reliable solution for installations in areas at risk of explosion. The cable is designed to function as a flexible control and measuring cable in intrinsically safe systems, where high interference resistance and safety are required. It is particularly useful in applications where installations are not grounded and have a separate electrical circuit.

Construction and application

The cable is characterized by a multi-wire copper core, PVC insulation and a copper braid screen that effectively protects against electromagnetic interference (EMC). This construction provides flexibility and durability, enabling easy installation even in difficult conditions. It is not intended for laying in the ground. The use of a plastic film further increases its mechanical strength. The blue PVC coating (RAL 5015) identifies it as an element of intrinsically safe systems of type -i-, compliant with DIN VDE 0165-1 / DIN EN 60079-14 / IEC 60079-14.

Properties and benefits

• Safety in EX zones: Designed for installation in potentially explosive areas, meeting strict safety standards.
• EMC shielding: Copper braid minimizes electromagnetic interference, ensuring stable signal transmission. For optimal protection, it is recommended to have two-sided contact of the braid with cable gland clamps.
• Flexibility and durability: Multi-wire copper core and flexible construction facilitate installation and ensure long-term operation.
• Resistance to external conditions: Resistant to UV radiation and weather conditions, allowing it to be used in outdoor installations.
• Wide temperature range: Allows operation in a temperature range of -40°C to +80°C (stationary) and -10°C to +80°C (flexible).
• Compliance with standards: Meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking) and the standards DIN VDE 0285-525-2-51 / DIN EN 50525-2-51 concerning PVC cables for intrinsically safe installations.
• Environmentally friendly material: Materials used in production do not contain silicone, cadmium or substances hindering painting.
• Convenient meter-based sale: Supplied in meter lengths, making it easy to precisely adapt to installation needs.

Remember that the minimum bending radius is 10x the cable diameter for flexible operation and 5x the cable diameter for fixed laying. AWG sizes are given for guidance only – the exact cross-section should be checked in mm².
