Introduction to H05BB-F and H07BB-F Cables
In the world of industrial electrical solutions, the H05BB-F and H07BB-F harmonized code cables stand out for their durability, flexibility, and specialised application in challenging environments. These rubber-insulated and sheathed electric cables, featuring a parallel EPDM tube and textile braid, are engineered for demanding applications, such as electric steam generator irons (commonly known as “vaporellas”). Their robust construction makes them ideal for use in low-temperature settings and automated stripping processes, ensuring reliability and efficiency.
Applications
The H05BB-F and H07BB-F cables are tailored for specific industrial applications:
Electric Steam Generator Irons: Their parallel EPDM tube and textile braid make them perfect for “vaporella” irons, which require flexible, heat-resistant cables.
Low-Temperature Environments: With operating temperatures as low as -40°C (H05BB-F), these cables are suitable for cold storage facilities and outdoor applications in harsh climates.
Automated Manufacturing: The cables’ design supports high stripping forces on automatic machines, streamlining production processes.
General Industrial Use: Their flexibility and durability make them ideal for machinery, portable tools, and equipment requiring reliable power delivery.
In South Africa, these cables are increasingly used in industries such as manufacturing, mining, and agriculture, where robust and flexible cabling is essential.

A Cape Town-based cold storage company integrated H05BB-F cables into its refrigeration units, operating at -30°C. The cables’ low-temperature resilience and flame-retardant properties provided a safe and efficient solution, contributing to a 20% reduction in energy losses compared to previous cabling systems.
Case Study 3: Mining Equipment in Johannesburg
A mining equipment supplier in Johannesburg implemented H07BB-F cables in portable machinery used in Gauteng’s gold mines. The cables’ higher voltage rating (450/750V) and robust sheath withstood the harsh underground conditions, improving equipment reliability and worker safety.
FAQs
1. What are the main differences between H05BB-F and H07BB-F cables?
The H05BB-F operates at 300/500V and is suited for lower-temperature environments (-40°C to +60°C), while the H07BB-F supports 450/750V and a wider temperature range (-25°C to +90°C), making it ideal for heavier-duty applications.
2. Are these cables suitable for outdoor use in South Africa?
Yes, both cables are designed for challenging environments. The H05BB-F is particularly effective in colder regions, while the H07BB-F handles higher temperatures, making it suitable for South Africa’s diverse climates.
3. Can these cables be used in automated manufacturing?
Absolutely. Their design supports high stripping forces on automatic machines, ensuring compatibility with modern manufacturing processes.
4. Are the cables flame-retardant?
Yes, both cables comply with VDE 0482-332-1-2/IEC 60332-1, ensuring they resist flame propagation.
5. Where can I source these cables in South Africa?
Reputable electrical suppliers in Johannesburg, Cape Town, and Durban stock H05BB-F and H07BB-F cables. Always ensure suppliers provide cables meeting HD 22.12 and CEI 20-19/12 standards.
The H05BB-F and H07BB-F harmonized code industrial cables are a testament to engineering excellence, combining flexibility, durability, and safety for specialised applications like steam generator irons and low-temperature environments. Their technical specifications, adherence to international standards, and proven performance in South African industries make them a reliable choice for manufacturers, miners, and cold storage operators. By understanding their capabilities and applications, businesses can harness these cables to enhance efficiency and safety in their operations.
