In the demanding world of industrial, construction, and event production, reliable power supply is non-negotiable. Flexible, durable cables are the lifelines of these operations. Two heavy weight champions in this category are the H07RN-F and SOOW cables. Both are renowned for their ruggedness and versatility in harsh environments, but they originate from different standardization systems and have distinct specifications. Choosing the right one is critical for safety, compliance, and performance. This guide will dissect the H07RN-F and SOOW cables, comparing their features to help you make an informed decision for your next project.
What is H07RN-F Cable?
The H07RN-F is a harmonized European standard cable, defined under HD 22.12 S2 and EN 50525-2-21. Its alphanumeric code is highly descriptive:
- H: Harmonized European standard.
- 07: 450/750V voltage rating (phase-to-earth/phase-to-phase).
- R: Rubber insulation.
- N: Chloroprene (Neoprene) rubber sheath.
- F: Flexible stranded conductors (Class 5 flexibility).
This cable is engineered for extreme conditions. Its synthetic rubber construction provides excellent resistance to oil, chemicals, abrasion, weathering (UV, ozone), and mechanical stress. It remains flexible in a wide temperature range, typically from -25°C to +60°C. Common applications include temporary power distribution on construction sites, wiring for industrial machinery, stage lighting and sound equipment, outdoor events, and use in workshops, quarries, and agricultural settings.
What is SOOW Cable?
The SOOW cable is a widely recognized American standard portable cord, governed by UL 62 and CSA C22.2 No. 49. Its designation follows the UL/CSA coding system:
- S: Service grade (600V), indicating heavy-duty performance.
- O: Oil-resistant jacket.
- O: Oil-resistant insulation.
- W: Weather and water-resistant (suitable for outdoor use).
SOOW cables are a North American industry staple. They feature oil-resistant synthetic rubber insulation and a similarly robust oil-, weather-, and abrasion-resistant jacket. They are designed for maximum flexibility and durability in tough industrial environments, with a common operating temperature range of -40°C to +60°C or 90°C depending on the specific rating. Their primary uses mirror those of H07RN-F but are tailored for markets following North American codes: factory automation, heavy-duty tools, generators, shipyards, and mining equipment.
Key Similarities Between H07RN-F and SOOW Cables
Despite different standards, these cables share a core mission:
- Extreme Durability: Both are built with synthetic rubber compounds to withstand severe mechanical abuse, crushing, and impact.
- Environmental Resistance: Excellent resistance to oil, grease, chemicals, ozone, sunlight (UV), and moisture.
- High Flexibility: Fine-stranded conductors allow for repeated bending, coiling, and movement, even in cold temperatures.
- Application Overlap: They are the go-to choices for similar harsh, mobile, or temporary power applications in construction, industry, and entertainment.

Choosing the Right Cable: H07RN-F or SOOW?
Your choice is primarily dictated by location and compliance requirements.
- Choose H07RN-F if: Your project is in Europe, the UK, Australia, or any region following IEC standards. It is required for CE marking and compliance with local electrical regulations (e.g., BS, VDE). It’s the specified cable for equipment and installations designed to European norms.
- Choose SOOW if: Your project is in the United States or Canada. It is necessary to meet National Electrical Code (NEC) and Occupational Safety and Health Administration (OSHA) regulations. The UL/CSA listing is often a mandatory safety requirement for site inspections and insurance.
- For Extreme Cold: If your application involves consistently sub-zero temperatures below -25°C, the wider low-temperature rating of many SOOW cables may be advantageous.
- For Global Projects: Always specify the cable standard required by the local authority having jurisdiction (AHJ). Using the wrong standard can lead to failed inspections, safety risks, and liability issues.
