In modern crane, gantry, and material handling systems, power and control cables are constantly exposed to frequent bending, mechanical stress, and electromagnetic interference (EMI). This raises a critical question for engineers and system designers:

Is there a low-voltage festoon cable that combines flexibility, EMC shielding, durability, and international compliance?

The (N)GRDGCGOEU Low Voltage Screened Festoon Cable (0.6/1 kV) is one of the most trusted answers. Designed in accordance with DIN VDE 0250-814, this cable is widely used in cranes, automated material handling systems, and machine tools, especially where EMC performance and operational reliability are essential.

What Is (N)GRDGCGOEU Festoon Cable Used For?

The (N)GRDGCGOEU is a low-voltage, round, screened power and control cable specifically designed for festoon systems operating under:

High mechanical stress
Frequent bending
High travel speeds
Strict EMC requirements

Typical applications include:

Gantry cranes and hall cranes
Rack-based material handling systems
Automated transportation systems
Machine tools with moving cable carriers
Flexible motor power supply connections

It is especially suitable for environments where power cables may interfere with data or control cables, or where EN 55011 / EN 55022 emission limits must be met.

Why Is EMC Shielding Important in Festoon Systems?

In industrial environments, variable frequency drives (VFDs), motors, and power electronics generate electromagnetic noise. Without proper shielding, this can cause:

Signal interference
Control errors
Sensor malfunction
PLC communication faults

The braided copper screen (>80% coverage) in the (N)GRDGCGOEU cable provides excellent EMC performance, with low transfer impedance across a wide frequency range (up to 30 MHz). This ensures:

Stable control signals
Reduced system downtime
Compliance with EMC regulations

How Should (N)GRDGCGOEU Cable Be Installed?

Key Installation Recommendations

Avoid torsional stress (not allowed)
Ensure proper grounding of the screen
Use appropriate cable carriers for weight and loop length
Do not exceed recommended cross-sections for festoon use
Consult manufacturer for speeds above 240 m/min

Correct installation significantly improves service life and EMC performance.

Frequently Asked Questions (FAQ)

Is (N)GRDGCGOEU suitable for outdoor use in Indonesia?

Yes. The PCP outer sheath resists UV, ozone, humidity, and oil, making it ideal for tropical environments.

Can this cable be used with frequency converters?

Yes. It supports up to 690 V AC with VFDs and offers excellent EMC protection.

Why is cross-section above 3×50 mm² not recommended for festoon systems?

Larger cross-sections increase weight and mechanical stress, which can reduce bending life and system reliability.

Is this cable approved under international standards?

Yes. It complies with DIN VDE 0250-814 and holds VDE and GOST-R approvals.

If you are designing or upgrading crane, port, or material handling systems and require a reliable, EMC-compliant festoon cable, the (N)GRDGCGOEU Low Voltage Screened Festoon Cable is a proven solution.
