Steel Wire Armoured XLPE Power Cable 90C 250C Withstand For Direct Burial

Steel Wire Armoured XLPE Power Cable – 90°C Continuous, 250°C Short-Circuit Withstand

Our steel wire armoured (SWA) XLPE power cable combines a cross-linked polyethylene insulation core with a galvanized steel wire or steel tape armour, making it the preferred choice for direct-burial and heavy-duty outdoor installations. The cable is rated 90°C continuously and withstands a 250°C short-circuit peak, while the outer sheath resists moisture, chemicals and UV exposure. With a designed service life of 40 years or more and full CE / IEC certification, it delivers reliable power in the harshest environments.

Key Features

• 90°C continuous rating, 250°C short-circuit withstand – high current-carrying capacity and thermal safety margin.
• Sunlight / UV protection – the outer sheath resists UV degradation, moisture and chemical attack for outdoor and buried service.
• Armored option for direct burial – galvanized steel wire (SWA) or steel tape (STA) armour protects against mechanical damage and supports direct burial.
• Long service life ≥40 years – ageing-resistant XLPE insulation and tough armour ensure decades of stable operation.
• LSZH / FR / NH customizable – sheath can be supplied low smoke halogen-free, flame-retardant or fire-resistant.
• CE / IEC certified – manufactured to IEC 60502 and CE requirements.

Applications

• Direct burial and underground power distribution
• Outdoor, industrial and construction sites
• Substations and feeder lines
• Wet, chemical or UV-exposed environments
