What Is XLPE Armoured Power Cable?
XLPE armoured power cable is a heavy-duty electrical power cable featuring cross-linked polyethylene (XLPE) insulation and a galvanized steel wire armour (SWA) layer, designed for reliable power transmission in mechanically demanding environments. It is the global standard for underground power distribution, industrial installations, and construction projects where cables require robust protection against physical damage, moisture, and environmental stress.
Our XLPE insulated steel wire armoured power cable (also known as SWA XLPE power cable or model designation YJV32) combines the excellent thermal and electrical properties of XLPE insulation with the superior mechanical protection of galvanized steel wire armour. The result is a cable that delivers 15–25% higher current-carrying capacity than PVC-insulated alternatives while withstanding direct burial, impact, crushing, and even rodent attack.

Cable Construction & Key Features
Our XLPE insulated armoured electrical cable features a multi-layer construction designed for maximum reliability. From the inner conductor to the outer sheath, every component is carefully engineered and quality-controlled:
Copper / Aluminum Conductor
High-purity annealed copper or aluminum conductor, Class 1 solid or Class 2 stranded per IEC 60228. Excellent conductivity and flexibility.
XLPE Insulation
Cross-linked polyethylene insulation rated at 90°C continuous operating temperature (250°C short circuit). Superior electrical, thermal, and aging resistance vs. PVC.
PVC Bedding & Filler
PVC inner bedding and non-hygroscopic fillers ensure a smooth, round cable profile and protect the insulation layer from armour damage.
Galvanized Steel Wire Armour (SWA)
Helically applied galvanized steel wires provide superior mechanical protection against impact, crushing, rodent attack, and tensile stress during installation.
PVC Outer Sheath
Black PVC outer sheath (ST2 type) provides protection against moisture, UV radiation, chemicals, and environmental corrosion. LSZH option available.
Color-Coded Core Identification
Standard color coding (Red/Yellow/Blue/Black + Green/Yellow earth) ensures easy and accurate installation, reducing wiring errors.
SWA vs STA: Which Armour Type Do You Need?
We offer both Steel Wire Armoured (SWA) and Steel Tape Armoured (STA) options. Understanding the difference helps you select the right cable for your application:

| Mechanical Strength | Superior - withstands direct impact & crushing | Moderate - light mechanical protection |
| Tensile Strength | High - suitable for vertical & long-span installation | Lower - best for horizontal runs on cable trays |
| Flexibility | Good flexibility | Stiffer, reduced bend radius |
| Typical Applications | Direct burial, underground, industrial, outdoor | Cable trays, indoor wiring, cable ducts |
| Model Designation | YJV32 (copper) / YJLV32 (aluminum) | YJV22 (copper) / YJLV22 (aluminum) |

FAQ
What's the difference between XLPE and PVC insulated cables?
XLPE (cross-linked polyethylene) insulated cables offer several key advantages over PVC insulated cables:
- Higher temperature rating: XLPE operates at 90°C continuously vs. 70°C for PVC, enabling 15–25% higher current-carrying capacity.
- Better short-circuit resistance: XLPE withstands 250°C short-circuit temperature vs. 160°C for PVC.
- Superior moisture and chemical resistance: XLPE performs better in wet and chemically aggressive environments.
- Longer service life: XLPE has better aging characteristics, typically lasting 30+ years vs. 20–25 years for PVC.
While PVC cables are cheaper upfront, XLPE armoured power cable offers better long-term value through higher performance and extended service life.
What does SWA stand for in SWA XLPE power cable?
SWA stands for Steel Wire Armoured. It refers to the layer of galvanized steel wires helically applied around the cable to provide mechanical protection. SWA cables are designed for:
- Direct burial underground without additional conduit
- Installations with risk of mechanical damage (impact, crushing)
- Areas with rodent or termite activity
- Vertical installations where tensile strength is needed
The alternative is STA (Steel Tape Armoured), which uses steel tape instead of wires. STA is lighter and cheaper but offers less mechanical protection than SWA.
How do I choose the right cable size for my project?
Choosing the right XLPE steel wire armoured cable size depends on several factors:
- Current carrying capacity: Based on the load current and installation method (direct burial, cable tray, etc.)
- Voltage drop: Ensure the voltage drop at full load is within acceptable limits (typically ≤ 5%)
- Short-circuit rating: The cable must withstand the available fault current
- Environmental conditions: Ambient temperature, soil thermal resistivity, grouping of cables
- Future expansion: Consider oversizing for future load growth
Our technical team can help you calculate the correct cable size. Just provide us with the load details, installation method, and environment, and we'll recommend the optimal specification.
