Description

IEC 0.6/1kV XLPE Insulation Steel Tape Armoured (STA) Power Cable

Product Overview

The IEC 0.6/1kV XLPE Insulation Steel Tape Armoured (STA) Power Cable is designed for fixed installation indoors and outdoors in cable ducts or directly in the ground. These cables are provided with mechanical protection and are therefore suitable for external use, direct burial, and areas where sudden mechanical stress is expected.

The cable features XLPE insulation, a PVC inner sheath, steel tape armour for multi-core constructions, and a PVC outer sheath. LSZH, PE, and flame-retardant options are available to meet project-specific requirements.

Features & Benefits

  • Conductor Temperature: Max. 90°C during normal operation

  • Short-Circuit Temperature: Max. 250°C for max. 5 seconds

  • Test Voltage: AC 3.5kV for 5 minutes, without breakdown

  • Mechanical Protection: Steel tape armour (STA) for multi-core cables; aluminium tape armour (ATA) for single-core cables

  • Conductor Options: Plain annealed copper or aluminium, Class 2, conforming to IEC 60228

  • Insulation: XLPE (cross-linked polyethylene)

  • Inner Sheath: PVC standard; LSZH and PE optional

  • Outer Sheath: PVC standard; flame retardant, PE, and LSZH optional

  • Installation: Suitable for fixed indoor and outdoor installation, cable ducts, direct burial, and areas with expected mechanical stress

Typical Applications
