Guide to Choosing 95mm Steel Armoured Cables for Power Safety

Imagine a sprawling industrial park where countless machines rely on uninterrupted power supply to function. Any disruption in electricity transmission could result in catastrophic losses. The solution? A cable capable of handling high loads while ensuring safety and reliability. The 95mm² steel wire armored (SWA) cable emerges as the ideal choice for such demanding applications.

The 95mm² SWA cable stands out for its exceptional mechanical protection, allowing direct underground installation without additional conduit protection. This significantly reduces project costs and simplifies construction. Its layered structure consists of:

• Conductor: Multi-strand copper wires ensure superior conductivity and flexibility for easier installation.
• Insulation: Cross-linked polyethylene (XLPE) provides excellent thermal resistance and electrical insulation for stable high-temperature operation.
• Filler: PVC material fills gaps between conductors and armor, preventing moisture ingress.
• Armor: Galvanized steel wires offer robust protection against external impacts, particularly for direct burial.
• Outer Sheath: PVC coating delivers weather and corrosion resistance against environmental factors.

This cable variant serves critical functions in multiple sectors:

• Transport Infrastructure: Powers railway systems, metro networks, and traffic signaling equipment.
• Industrial Facilities: Supports heavy machinery and production lines in factories and power plants.
• Utility Installations: Used in cable ducts and warehouse rooftops for equipment power supply.

Understanding these parameters ensures optimal cable selection:

• Current Rating: 289A (direct burial) - requires adjustment for ambient temperature and installation method
• Diameter: Approximately 37mm (varies by manufacturer)
• Temperature Range: Operational up to 90°C; minimum bending at 0°C
• Bending Radius: Minimum 6x cable diameter for fixed installations
• Standards Compliance: Meets BS 5467 (UK standard)
• Voltage Rating: 600/1000V (higher ratings available)

• Verify copper conductor purity for optimal conductivity
• Confirm XLPE insulation quality for thermal stability
• Inspect galvanized steel armor for corrosion resistance
• Check for relevant certifications (e.g., CCC, CE)

• Employ qualified electricians adhering to safety codes
• Maintain proper bending radius during installation
• Use appropriate cable clamps (e.g., CC16 type for 95mm² cables)
• Conduct post-installation insulation resistance tests

• Regular visual inspections for damage or wear
• Periodic insulation resistance measurements
• Connection point monitoring at terminals and joints
• Protection from mechanical stress and chemical exposure

While cable calculators provide approximate sizing, consulting certified electricians remains crucial for accurate dimensioning based on specific project requirements and local regulations.

Proper installation requires compatible accessories:

• Terminations: BW40 type for indoor use; CW40 for outdoor applications
• Clamps: Size-matched to cable diameter (CC16 recommended for 95mm² cables)

The 95mm² steel wire armored cable represents a robust, reliable solution for industrial power distribution. Its combination of mechanical durability, electrical performance, and installation flexibility makes it indispensable for critical infrastructure projects. Proper selection, installation, and maintenance ensure long-term operational safety and efficiency.
