The AL/XLPE/CWS/STA/PVC three-core power cable 18/30kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 aluminium conductor). It adopts aluminium conductors, XLPE insulation, copper wire screen (CWS), steel tape armour (STA), and PVC outer sheath, delivering a cost-efficient and mechanically protected solution for high medium-voltage underground distribution systems.
The three-core structure is suitable for balanced three-phase networks, while the STA layer provides reliable resistance to external mechanical stress and soil pressure, making it suitable for direct burial and long-term underground operation.

Conductor: Stranded aluminium conductor (Class 1 or Class 2)
Conductor Screen: Semi-conductive layer for electric field control
Insulation: XLPE with high thermal endurance and dielectric strength
Insulation Screen: Semi-conductive layer for uniform stress distribution
Metallic Screen: Copper wire screen (CWS) for fault current return and grounding
Armour: Stainless steel tape armour (SSTA) for mechanical protection and anti-rodent performance
Bedding: Protective layer separating armour from insulation system
Outer Sheath: PVC (ST2), moisture and abrasion resistant
Design: Single-core, SSTA armoured high-voltage MV cable (18/30 kV)
The 18/30kV aluminium STA three-core cable is widely used in medium-voltage underground systems where both electrical performance and mechanical protection are required. It is commonly selected for cost-sensitive infrastructure projects with long service life expectations.
Typical applications include:
Underground MV distribution networks
Substation feeder and outgoing circuits
Industrial power distribution systems
Urban utility backbone networks
Road, railway, and tunnel crossings
Renewable energy collection and evacuation systems
Direct buried cable routes in protected trenches

It’s easier to install. All three phases are in one cable, so less trench space and fewer laying steps.
Slightly. The cable is heavier and less flexible than single-core, so drum handling and pulling need more care.
Yes, but trench bedding must be well prepared to avoid stress on the outer sheath and armour.
Yes. It needs a larger bending radius and smoother routing compared to single-core cables.
It saves space and reduces installation complexity, especially where routes are tight.
The phases are more compact, so external magnetic field is lower and system layout is simpler.
