Armoured MV Single-Core Power Cables, Cu XLPE,CTS or CWS,AWA, PVC Sheath, IEC 60502-2

As a reliable Chinese cable manufacturer and supplier, this IEC 60502-2 armoured medium voltage single-core power cable produced by Taitong Cable is a popular choice for EPC contractors, power utilities and engineering procurement projects. Equivalent to N2XSRY, it adopts high-conductivity copper conductor for stable power transmission, matched with XLPE insulation boasting outstanding dielectric strength, low dielectric loss and excellent thermal ageing resistance. Available with CTS copper tape screen or CWS copper wire screen to balance electric field, control partial discharge and reduce EMI. The AWA aluminium wire armour delivers robust lightweight mechanical protection against crush and impact, and the PVC outer sheath provides reliable moisture, oil and weather resistance for long-term underground and tunnel service. This armoured medium voltage power cable is widely specified for substations, industrial power distribution and underground cable network projects. Taitong Cable supplies custom cable sizes and full factory test reports for global bulk cable clients.

Construction of Armoured MV Single-Core Power Cables, Cu XLPE, CTS or CWS, AWA, PVC Sheath 

---

Conductor (Cu):Stranded copper conductor ( either of class 1 or class 2 of plain or metal-coated annealed copper), IEC 60228

Conductor Screen: An extruded semi-conducting compound applied directly over the copper conductor to smooth out surface irregularities and evenly distribute the electrical field.

Insulation: Cross-Linked Polyethylene (XLPE) extruded over the conductor screen. It offers high dielectric strength and continuous operating temperatures up to 90°C (with short-circuit ratings up to 250°C).

Insulation Screen: A second extruded semi-conducting layer applied over the XLPE insulation to maintain a uniform electrical field around the core.

Metallic Screen: CWS Copper Wire Screen or CTS Copper Tape Screen. Carries fault or earth leakage current and provides an electrostatic shield.

Bedding / Inner Sheath: An extruded layer of Polyvinyl Chloride (PVC) placed over the core assembly to cushion and protect the underlying layers from the metallic armour.

Armour (AWA - Aluminium Wire Armour):A closed layer of non-magnetic round aluminium wires.

Crucial note: 

Single-core AC power cables must use non-magnetic armour (like aluminium rather than steel) to prevent excessive inductive heating and magnetic eddy currents. It provides mechanical protection against crushing and digging impacts.

Outer Sheath: An outer jacket made of extruded PVC compound (often flame-retardant grade ST2) that protects the entire cable against moisture, sunlight, soil chemicals, and physical abrasion.

Reference standards for Cu/XLPE/CTS (or CWS)/AWA/PVC single-core medium voltage (MV) power cables typically align with international and regional technical codes:

Primary International Standards 

---

IEC 60502-2: Extruded insulation power cables for rated voltages 6 kV (7.2 kV) up to 30 kV (36 kV)

IEC 60228: Insulated cable conductors

IEC 60332: Fire performance tests for cables

EN 60502-2: European adoption of IEC 60502-2

Alternative / Regional Standards

DIN VDE 0276‑620 / HD 620 S2: European equivalent specification (N2XSRY)

BS 6622: British standard for MV armoured XLPE cables with AWA

IS 7098 (Part 2): Indian regional standard

Key Applications of Medium Voltage Copper, XLPE, AWA, PVC Electric Cables 

---

This armoured medium voltage single-core cable is designed for demanding medium-voltage distribution systems, engineered for fixed installations demanding reliable mechanical protection, suited for underground burial, ducts, tunnels, cable trays and riser routes, and delivers stable power transmission and distribution across municipal, utility, industrial and EPC projects.

1, Municipal and regional underground power distribution (direct burial or in cable ducts)

2, Substation incoming / outgoing feeders for transformers and switchgear

3, Heavy industrial plants, manufacturing and processing facilities

4, Power station main and auxiliary power circuits

5, Mining and heavy infrastructure with mechanical stress and moisture exposure

6, Indoor, tunnel, cable tray and vertical riser installations, UV-resistant PVC sheath for outdoor exposed runs

7, Renewable energy and general EPC power transmission projects

Technical and Operating Parameters of Armoured MV Single-Core Power Cables, Cu XLPE, CTS or CWS, AWA, PVC Sheath, IEC 60502-2 

---

Voltage Ratings: Commonly manufactured across medium-voltage ranges such as 3.8/6.6 kV (7.2 kV max), 6.35/11 kV, 8.7/15 kV, up to 19/33 kV (or 26/35 kV).

Installation: Fixed installation, direct burial, duct, tunnel, cable tray.

Conductor Temperature Ratings:

Normal Continuous Operation: Up to 90°C.

Short-Circuit Rating (5s max): Up to 250°C

Installation Temperature: Ambient temperature during installation should not fall below 0°C.

Minimum Bending Radius: Typically ≥20 x Overall Diameter (D) for single-core cables.

Note:

Medium-voltage single-core cables with metallic screens and wire armour require a larger radius (20D) compared to low-voltage or multi-voltage equivalents to prevent over-bending the rigid copper conductor, cracking the XLPE insulation, or overstressing the aluminium wire armour (AWA) and PVC sheath.

Applicable Standards: Built in accordance with standards such as IEC 60502-2, BS 6622, or regional equivalents.

The cross-sectional area of the copper conductor: 10mm² to 400mm²，larger sizes to be specified in your inquiry.
