T2X — Bundle Assembled Aerial Cables XLPE-insulated

Product Overview

T2X is an XLPE-insulated bundled aerial cable designed for low-voltage overhead power distribution networks with a rated voltage of 0.6/1 kV (U₀/U).

The cable consists of aluminium phase conductors and a steel-aluminium supporting neutral conductor. The phase conductors are insulated with cross-linked polyethylene (XLPE), specifically TIX 2 type, providing electrical insulation for overhead installation.

Depending on the conductor cross-section, the phase conductor is manufactured as a solid aluminium conductor or a concentrically stranded aluminium conductor. The steel-aluminium neutral conductor provides mechanical support for the aerial cable assembly.

T2X cable is suitable for single-phase and three-phase service connections, residential electricity supply and public lighting networks.

Applications

T2X bundled aerial cable is designed for low-voltage overhead power distribution networks with rated voltages up to 0.6/1 kV.

Typical applications include:

• Single-phase electrical service connections
• Three-phase electrical service connections
• Residential electricity distribution
• Three-phase power supply networks for household consumers
• Single-phase public lighting networks
• Two-phase public lighting networks
• Three-phase public lighting networks
• Low-voltage overhead distribution systems

2. Supporting Neutral Conductor

• Material: Steel-aluminium
• Construction: Concentric stranded (rm)
• Function: Mechanical support for the bundled aerial cable

3. Insulation

• Material: Cross-linked polyethylene (XLPE)
• Insulation type: TIX 2
• Colour: Black
