Engineered for Extreme Industrial Environments

Cu EPR HOFR Flexible Cables are meticulously crafted to withstand harsh operating conditions typical in heavy industries, mining, and mobile equipment. Their EPR insulation and HOFR sheath provide excellent flame, oil, and weather resistance while maintaining flexibility, allowing for frequent movement and reeling. These cables ensure operational safety and reduce maintenance needs, making them ideal for both permanent and portable power connections.

Compliance and Safety Standards

Manufactured in adherence to global safety and quality benchmarks such as IS 9968 Part 1, IEC 60502-1, and IEC 60332-1, these cables are flame retardant, halogen-free, and meet key certifications like REACH and RoHS. Each cable undergoes rigorous dielectric strength testing, ensuring safe operation up to 3.5 kV and reliability in critical industrial applications.

Tailored for Versatility and Longevity

Available in a wide range of core counts and sizes, Cu EPR HOFR Flexible Cables accommodate diverse installation needs. Their robust construction, resistance to abrasion, fuel, grease, and UV rays, coupled with high tensile strength, makes them suitable for both indoor and outdoor deployments. The cables are supplied in 100-meter lengths for convenient installations and efficient logistics.

FAQs of Cu Epr Hofr Flexible Cables:

Q: How are Cu EPR HOFR Flexible Cables typically used in industrial settings?

A: These cables are most commonly employed in mobile power applications, cranes, conveyors, mining machinery, and portable devices. Their flexibility and durable design allow them to support both permanent and temporary installations, especially where frequent movement or reeling is required.

Q: What are the main benefits of using EPR (Ethylene Propylene Rubber) insulation in these cables?

A: EPR insulation offers exceptional electrical properties, high resistance to heat, chemicals, and abrasion, and remains flexible at low temperatures. This ensures longer cable life, operational safety, and reliable performance under varied environmental conditions.

Q: When should I choose a HOFR (Heat and Oil Flame Retardant) cable over conventional flexible cables?

A: HOFR cables should be selected when applications demand superior flame retardance, resistance to oils, chemicals, and UV exposure, as well as high mechanical durability. Situations like mining, outdoor installations, or locations with risk of fire or chemical exposure particularly benefit from HOFR cables.

Q: Where can these cables be installed and stored safely?

A: These cables are suitable for both indoor and outdoor installations, including environments exposed to weather, UV rays, and mechanical stresses. They can be safely stored at temperatures between -30C and +70C, provided they are shielded from direct mechanical damage and excessive moisture during storage.

Q: What process ensures the quality and compliance of Cu EPR HOFR Flexible Cables?

A: Each cable is manufactured and tested as per IS, IEC, and EN standards, including flame retardance and dielectric strength verification up to 3.5 kV. Compliance with REACH and RoHS ensures that the cables are environmentally safe and free from restricted hazardous substances.

Q: How does the cables maximum current capacity vary and where can I find the limits?

A: Maximum current capacity depends on the cables size and the number of cores. Each cables rating aligns with IS 9968 and IEC current capacity chartsfor instance, a 2.5 sqmm 3 core cable supports up to 28A. Refer to the product datasheet or relevant standards for specific ratings per size and configuration.
