3. Design and Construction

3.1 Conductor

The heart of the Plano-Flex NGFLGOEU lies in its meticulously engineered conductor system, utilizing high-purity electrolytic copper that provides exceptional electrical conductivity and corrosion resistance. For conductor cross-sections up to 25 mm², the cable employs extra-fine stranded copper construction classified as Class 6 according to IEC 60228 standards, delivering maximum flexibility for demanding festoon applications.

Larger conductor sizes above 35 mm² utilize Class 5 stranding, which maintains excellent flexibility while providing the structural integrity necessary for higher current-carrying capacity. This graduated approach to conductor design ensures optimal performance across the entire range of available configurations.

The conductor stranding pattern follows a carefully engineered sequence that minimizes stress concentration during flexing cycles. Each individual copper strand undergoes precision drawing and annealing processes to achieve the ideal balance between conductivity and mechanical flexibility. This results in conductors capable of withstanding millions of flex cycles without wire breakage or electrical degradation.

3.2 Insulation & Shielding

The insulation system utilizes advanced EPR insulation (PROTOLON 3GI3 compound) manufactured in accordance with DIN VDE 0207-20 specifications. This high-performance elastomeric insulation provides exceptional dielectric strength while maintaining flexibility across a wide temperature range.

Optional tinned copper braid shielding offers electromagnetic interference (EMI) protection with coverage ratings between 60-80%, depending on application requirements. The shielding construction employs tinned copper strands woven in a precise pattern that maintains electrical continuity even during extreme flexing operations.

For applications requiring enhanced EMI protection, the shielded flat cable configuration includes a drain wire for simplified grounding connections. The shielding system effectively attenuates electromagnetic interference while allowing the cable to maintain its exceptional flexibility characteristics.

3.3 Sheath

The outer sheath utilizes premium chloroprene rubber (CR) compound type 5GM3, engineered specifically for demanding industrial environments. This CR sheathed cable provides exceptional resistance to flame propagation, UV radiation, ozone exposure, and mechanical abrasion.

The flame-retardant properties meet stringent international safety standards, ensuring personnel safety and equipment protection in industrial installations. The UV and ozone resistance characteristics enable reliable outdoor operation without degradation of mechanical or electrical properties over extended service life.

4. Electrical & Thermal Properties

The Plano-Flex NGFLGOEU operates at a rated voltage of 300/500V with peak voltage capability up to 600V, making it suitable for both power distribution and control signal applications. This 600V flat control cable undergoes rigorous electrical testing to ensure compliance with international safety standards.

Testing protocols include AC voltage tests at 2 kV for individual control cores and 2.5 kV for overall cable assembly, performed for five minutes to verify insulation integrity. These comprehensive tests ensure the VDE-certified flat cable meets the highest safety standards for industrial applications.

Thermal performance characteristics include a maximum continuous conductor temperature of 90°C during normal operation, with short-circuit capability up to 250°C for one second. This thermal rating enables the cable to handle both steady-state loads and emergency overload conditions without compromising safety or performance.

The cable's thermal design incorporates optimized conductor spacing and advanced insulation materials that facilitate heat dissipation while maintaining compact dimensions. This thermal management approach ensures stable electrical performance across the entire operating temperature range.

5. Mechanical & Flexibility Performance

Mechanical performance represents a critical design parameter for festoon cable applications, and the Plano-Flex NGFLGOEU delivers exceptional capabilities in this regard. The cable withstands tensile loads up to 15 N/mm², providing substantial margin for installation tensions and operational stresses.

Festoon travel speeds accommodate demanding industrial requirements, supporting speeds up to 180 m/min in motorized systems and 160 m/min in non-motorized applications. These high-speed capabilities enable the cable to support rapid material handling operations without mechanical stress or electrical degradation.

The minimum bending radius specification of 5× cable thickness ensures proper installation practices while maximizing system flexibility. This generous bending radius prevents conductor stress concentration and insulation damage during installation and operation.

Flat cable bending radius calculations must consider both static installation requirements and dynamic flexing applications. The cable's flat profile distributes bending stresses across a larger area compared to round cables, resulting in extended service life and enhanced reliability.

Flex life testing demonstrates the cable's ability to withstand millions of flex cycles under specified conditions, making it ideal for continuous-duty applications. The testing protocol simulates real-world operating conditions to validate long-term performance expectations.

6. Environmental & Chemical Resistance

Environmental resistance capabilities distinguish the Plano-Flex NGFLGOEU from standard industrial cables. The cable demonstrates exceptional oil resistance according to DIN VDE 0473-404 standards, enabling reliable operation in oil-contaminated industrial environments without sheath degradation.

UV resistance and ozone resistance characteristics ensure reliable outdoor operation without material degradation from solar radiation or atmospheric ozone exposure. These properties make the UV-resistant festoon cable suitable for both indoor and outdoor installations.

The operating temperature range accommodates diverse environmental conditions:

• Flexing applications: -35°C to +80°C

• Fixed installations: -50°C to +80°C

This wide temperature range enables the oilproof flat crane cable to operate reliably in extreme climates, from Arctic installations to tropical industrial environments. The cable maintains mechanical flexibility and electrical performance across this entire temperature spectrum.

Chemical resistance extends beyond oil to include resistance to common industrial chemicals, cleaning solvents, and atmospheric pollutants. This comprehensive chemical resistance ensures long service life in diverse industrial environments.
