Introduction

In the maritime industry, where safety and reliability are paramount, the choice of cabling can significantly impact operational efficiency and crew safety. The 0.6/1 kV Mica Tape + Cross-Linked Polyethylene (XLPE) Insulated, Low Smoke Zero Halogen (LSOH) Sheathed, Armoured Fire-Resistant Power and Control Cables (Single Core) are engineered to meet the stringent demands of marine environments. These cables, adhering to international standards such as IEC 60092 and IEC 60331, are designed for fixed installations on ships, offering fire resistance, flame retardancy, low smoke emission, and halogen-free properties.

Advantages of 0.6/1 kV Fire-Resistant Cables

Fire Resistance

The mica tape insulation ensures circuit integrity during fire exposure, maintaining power supply to critical systems such as emergency lighting, alarms, and communication systems. This is vital for safe evacuation and firefighting efforts on ships.

Flame Retardancy

Compliance with IEC 60332 standards ensures the cables do not propagate flames, reducing the risk of fire spread in confined maritime spaces.

Low Smoke and Halogen-Free Properties

The LSOH (SHF1) sheath minimises smoke and toxic gas emissions, improving visibility and reducing health risks for crew members during fire incidents. This is particularly crucial in enclosed areas like engine rooms or cabins.

Mechanical Protection

The copper wire braid armour provides robust protection against physical damage, ensuring long-term reliability in harsh maritime conditions, such as vibrations, impacts, or exposure to saltwater.

Thermal and Environmental Resilience

The XLPE insulation and LSOH sheath enable the cables to operate reliably across a wide temperature range, making them suitable for South Africa’s diverse coastal climates, from the cold Benguela Current to the warmer Agulhas Current.

Versatility

Available in various cross-sectional sizes and conductor classes (Class 2 or Class 5), these cables can be tailored to specific power and control requirements, from lighting circuits to heavy machinery.

Applications in Maritime Environments

These cables are designed for fixed installations on ships, including:

Power Distribution: Supplying electricity to critical systems such as propulsion, navigation, and communication equipment.
Control Systems: Supporting control circuits for automated systems, ensuring operational efficiency.
Emergency Systems: Powering emergency lighting, alarms, and firefighting equipment, where fire resistance is critical.

Case Studies in South African Maritime

Case: Offshore Supply Vessel in Durban

In 2023, a South African offshore supply vessel operating out of Durban was retrofitted with 0.6/1 kV Mica Tape + XLPE Insulated, LSOH Sheathed, Armoured Fire-Resistant Cables. The vessel, servicing oil rigs in the Indian Ocean, required cables that could withstand high mechanical stress and maintain circuit integrity during potential fire incidents. The 1×50 mm² single-core cables were installed for power distribution to the vessel’s navigation and communication systems. The copper wire braid armour protected the cables from damage caused by vibrations and equipment movement, while the LSOH sheath ensured low smoke emissions, critical for crew safety in enclosed spaces. Post-installation, the vessel reported enhanced reliability and compliance with international safety standards, contributing to safer operations.

Conclusion

The 0.6/1 kV Mica Tape + XLPE Insulated, LSOH (SHF1) Sheathed, Armoured Fire-Resistant Power and Control Cables (Single Core) are a cornerstone of modern maritime electrical systems. Their fire resistance, flame retardancy, low smoke and halogen-free properties, and robust mechanical protection make them ideal for the demanding conditions of ships. In South African contexts, these cables enhance safety and reliability for vessels operating from key ports like Durban and Cape Town. By adhering to stringent international standards and offering versatility across applications, these cables ensure operational efficiency and crew safety. As the maritime industry evolves, continued investment in innovative cable technologies will further strengthen South Africa’s position in global maritime operations.
