What Are H05SS-F and H05SST-F Cables?

The H05SS-F and H05SST-F cables are heavy-duty, harmonized, multi-core cables designed for use in extreme temperature ranges, from -60°C to +180°C, with a short-circuit temperature tolerance of up to +220°C. Their silicone insulation and jacket provide exceptional resistance to heat, chemicals, oils, and acids, making them ideal for demanding industrial settings. The key difference between the two lies in the H05SST-F’s additional polyester fiber braid, which enhances tear resistance and mechanical protection, particularly for lighting applications.

These cables are harmonized under European standards, meaning they carry the “H” designation, which ensures compliance with the European Committee for Electrotechnical Standardization (CENELEC). This harmonization makes them suitable for export to or use in European markets, a critical feature for industries operating globally, including those in South Africa.

Standards and Approvals

The H05SS-F and H05SST-F cables are compliant with several international standards, ensuring their reliability and safety:

• HD 22.15 S1: Harmonized European standard for silicone cables.

• VDE-0282 Part 15 and VDE-0250 Part-816 (N2MH2G): German standards for cable construction and performance.

• CE Low Voltage Directive 72/23/EEC & 93/68/EEC: Compliance with European safety regulations.

• ROHS Compliant: Free from hazardous substances, aligning with environmental regulations.

• IEC Standards: Including IEC 60332-1 (flame retardancy), IEC 60754-1 (halogen-free), and IEC 60754-2 (low smoke), ensuring safety in critical applications.

Applications of H05SS-F/H05SST-F Cables

The H05SS-F and H05SST-F cables are designed for environments where standard cables would fail. Their primary applications include:

• Steel Mills and Foundries: These cables withstand the extreme heat and mechanical stress of molten metal processing.

• Glass Factories: The UV-resistant and heat-tolerant silicone jacket ensures reliable performance in high-temperature glass production.

• Baking Equipment and Burners: Used in industrial ovens and burners where temperatures reach up to 180°C.

• Heating and Lighting Systems: The H05SST-F’s polyester braid makes it ideal for mechanically protected lighting in industrial settings.

• Chemical and Oil Industries: The silicone jacket’s resistance to chemicals and oils ensures longevity in harsh chemical environments.

Frequently Asked Questions (FAQs)

1. What is the difference between H05SS-F and H05SST-F cables?

The primary difference is that H05SST-F cables feature an additional polyester fiber braid, which enhances tear resistance and mechanical protection, making them ideal for lighting applications in industrial settings.

2. Can these cables be used outdoors?

No, H05SS-F and H05SST-F cables are not permitted for outdoor use due to their sensitivity to prolonged UV exposure without additional protection.

3. What industries benefit most from these cables?

Steel mills, foundries, glass factories, chemical plants, and heating/lighting systems benefit most due to the cables’ high-temperature tolerance and chemical resistance.

4. Are these cables safe in fire-prone environments?

Yes, they are flame-retardant (IEC 60332-1), halogen-free (IEC 60754-1), and low-smoke (IEC 60754-2), making them safe for use in fire-prone settings.

5. How do these cables support South Africa’s industrial needs?

Their durability, heat resistance, and compliance with international standards make them ideal for South Africa’s steel, glass, and renewable energy industries, supporting both operational efficiency and export compliance.

The H05SS-F and H05SST-F harmonized code industrial cables are a testament to the power of specialized engineering in meeting the demands of extreme industrial environments. With their robust construction, compliance with stringent European standards, and versatility in applications ranging from steel mills to glass factories, these cables are a vital component in modern industrial systems. In South Africa, where industries face challenges like load shedding and the need for global competitiveness, these cables offer a reliable, safe, and sustainable solution. By understanding their technical specifications, standards, and real-world applications, industries can harness the full potential of these cables to drive efficiency and innovation.
