RR Kabel 25mm² Single-Core Building Wire

RR Building Wire 25mm² Single Core

The RR Building Wire 25mm² Single Core is a large-section conductor for sub-main distribution, high-current feeder cables, and industrial power wiring in UAE buildings. Suitable for installation in conduit, trunking, and cable trays where high current-carrying capacity is required at medium distribution voltage levels.

Key Features

• 25mm² conductor for heavy sub-main and feeder applications
• Single-core for flexible multi-phase circuit construction
• PVC insulation for conduit and trunking installations
• Sold per metre for accurate large-project ordering
• Genuine RR Cables quality

Technical Specifications

Applications

• Sub-main distribution board feeder cables
• Industrial machinery and plant power wiring
• High-current commercial installation wiring
• Conduit and cable tray installations

FAQ

• What does the 25mm² cross-section rating mean, and how do I pick the right size for my circuit?
  The mm² figure is the conductor's copper cross-sectional area, which determines how much current the wire can safely carry and its voltage drop over distance. Larger cross-sections carry higher currents over longer runs. Confirm the correct size for your circuit's load and cable length against the applicable wiring regulations (or ask our technical team) before ordering — this listing is for the conductor itself, not a substitute for a proper circuit design.
• Can I order an exact length, and how is the price calculated?
  Yes — this wire is sold per metre, so you enter the exact quantity of metres you need at checkout and are charged accordingly. There's no minimum roll or coil requirement; order 5 metres or 500.
• What's the difference between Single-Core Building Wire and RR Kabel's Flexible Panel Wire?
  Building Wire uses a solid or low-strand-count conductor designed for fixed, permanent installation in walls, conduit, and trunking. Flexible Panel Wire uses a finer, multi-strand flexible conductor designed for movement and repeated flexing inside control panels and switchboards. Use Building Wire for fixed circuit wiring; use Flexible Panel Wire for panel/control cabinet internal wiring.
• Does this need to be installed by an electrician?
  Yes. Fixed building wiring must be installed and terminated by a licensed electrician in line with UAE wiring regulations — this is a supply-only conductor, not a DIY plug-and-play product.
• Why do the colours (Red/Yellow/Blue/Black) matter, and can I mix colours in one order?
  Colour-coding identifies phase, neutral, and circuit function so an electrician can trace and safely isolate circuits later. You can order any mix of colours and lengths in the same purchase — each colour is simply a separate variant of the same 25mm² wire.
