Application

IEC 60502-2 three-core SWA cable (3.6/6kV to 18/30kV) for mining, oil & gas refineries, heavy machinery, and high pulling load applications. Galvanized steel wire armor withstands severe impacts and high tensile forces. Direct burial recommended.

Core Strengths

High-tension projects demand strongest mechanical protection. Our SWA galvanized steel wire armor withstands extreme pulling loads and severe impacts. Built for toughest conditions. Factory direct.

Standard

IEC60502, SANS 1339, BS 6622, AS/NZS1429.1, NFC 33226, CSA C 68.3, ICEA S 93-639 , ICEA S 94-649

Construction

Conductor: Aluminum (Al), stranded (class 2)

Conductor screen: Semiconductive layer

Insulation: XLPE (cross-linked polyethylene)

Insulation screen: Semiconductive layer

Copper tape screen: Helically applied copper tape

Filler: Polypropylene (PP) or PVC filler

Wrapping tape: Binding tape over assembled cores

Inner sheath: PVC

Armor: Galvanized steel tape

Outer sheath: Black PVC

Features

Rated voltage: 6kV to 30kV (Uo/U up to 18/30kV)

Aluminum conductor – lightweight, cost‑effective

XLPE insulation – 90°C continuous, 250°C short‑circuit

Copper tape screen – uniform electric field, corona suppression, fault return path

Steel tape armor – excellent crush resistance and rodent protection

Black PVC outer sheath – UV resistant, suitable for outdoor and direct burial

Ideal for industrial plants, power distribution, underground tunnels

100% factory tested to IEC 60502‑2
