Construction of Medium Voltage Copper XLPE PVC Power Cables 

---

Copper Conductor: Plain annealed copper, Class 2 stranded (IEC 60228) to reduce overall diameter and maximize current-carrying capacity and withstands short-circuit currents.

Conductor Screen (Inner Semiconductive Layer): Non-metallic semiconductive compound.

XLPE Insulation: Extruded cross-linked polyethylene (XLPE). Serves as the primary dielectric barrier with high insulation resistance, low dielectric loss, and a continuous operating temperature rating of +90°C.

Insulation Screen (Outer Semiconductive Layer): Extruded bonded or strippable semiconductive compound applied over the XLPE core maintains a uniform electric field and controls electrical stress concentration.

Metallic Screen: Copper tape or copper wire screen provides an earth-fault current path, maintains earth potential, and reduces electromagnetic interference (EMI).

(Note: Magnetic metallic armour is generally omitted on single-core AC medium-voltage cables to prevent excessive inductive heating).

Outer PVC Sheath: Polyvinyl chloride (PVC) compound Type ST2 forms a robust outer sheath to protect internal components from moisture, chemical corrosion, weathering and mechanical abrasion.

Applications of Single‑Core MV Cu XLPE PVC Power Cables 

---

These single‑core medium‑voltage copper XLPE PVC power cables are designed for fixed indoor, outdoor and underground laying within medium‑voltage distribution networks.

1, Urban and municipal power grid: Connection between distribution substations, ring main units and transformer stations for urban power supply.

2, Industrial power systems: Power feed for heavy‑duty workshops, production lines, pumping stations and industrial auxiliary facilities.

3, Commercial complex supply: Medium‑voltage incoming and outgoing lines for shopping malls, office buildings, hospitals and data centres.

4, Indoor substation wiring: Cable connections inside package substations and switchgear rooms.

5, Underground trench or direct burial installation: Laying in cable trenches, cable tunnels or direct burial under normal soil conditions without explosive gas.

6, Outdoor overhead‑to‑underground transition: Transition segments between overhead MV lines and underground cable networks.

Standards

MV single‑core Cu/XLPE/CTS‑CWS/PVC, non‑flame retardant

MV single‑core Cu/XLPE/CTS‑CWS/PVC, flame retardant FR-C

MV single‑core Cu/XLPE/CTS‑CWS/LSZH sheath, low smoke halogen‑free, flame retardant FR-C

MV single‑core Cu/XLPE/CTS or CWS Screen/PVC, non‑flame retardant

MV single‑core Cu/XLPE/CTS or CWS Screen/PVC, flame retardant FR‑C

MV single‑core Cu/XLPE/CTS or CWS Screen/LSZH sheath, low smoke halogen‑free, flame retardant FR‑C

MV single‑core Cu/XLPE/CTS or CWS Screen/AMA Armour/PVC

The cable adopts aluminium wire armour (AMA) over the metallic screen, delivering robust mechanical protection against heavy mechanical load, rock impact and abrasion for direct burial and tunnel laying.

MV single‑core Cu/XLPE/CTS or CWS Screen/ATA Armour/PVC

The cable is fitted with aluminium tape armour (ATA) above the metallic screen, offering reliable mechanical shielding against mechanical damage, moisture and stone impact for underground and duct installation.

Magnetic steel tape armour is generally omitted on single‑core AC medium‑voltage cables, and non‑magnetic aluminium armour is used where mechanical protection is required to prevent excessive inductive heating.

(These standards cover conductor resistance, power frequency withstand voltage, partial discharge, insulation resistance, thermal ageing, flame spread, halogen content, acid gas and smoke density tests.)

Electric Parameters of Unarmoured MV CU/XLPE/PVC Electric Cable 

---

Rated voltages U 0 /U(U m ) :3,6/6 (7,2) – 6/1 0 (1 2) – 8,7/1 5 (1 7,5) – 1 2/20 (24) – 1 8/30 (36) kV.

(NOTE The voltages given above are the correct designations although in some countries other designations are used, e.g. 3,5/6 – 5,8/1 0 – 1 1 ,5/20 – 1 7,3/30 kV.)

Maximum Conductor Operating Temperature: 90°C (continuous).

Short-Circuit Temperature: 250°C (for up to 5 seconds).

Conductor cross‑section: Typically 10 to 400 mm²; larger sizes available upon enquiry.

The oversheath is normally black, but a colour other than black may be provided by agreement between the manufacturer and customer, subject to its suitability for the particular conditions under which the cable is to be used.

Minimum installation bending radius: 15 × D; minimum dynamic bending radius: 20 × D (D = overall cable diameter).

Routine test: 3.5 U₀, 5 min power frequency withstand; partial discharge ≤10 pC @ 1.73 U₀

Type test: thermal ageing, hot set, sheath test; flame & smoke tests per IEC 60332‑3‑24, IEC 60754‑1/2, IEC 61034‑2

(Static vs. Dynamic: The tighter limit applies only to a fixed, finished bend after installation. While being pulled through ducts or around corners (dynamic pulling), a wider radius and cable rollers/shoes should be used.)
