How to Select the Right Power Cable
Choose Copper Conductor When Reliability & Compact Installation Matter
Copper‑conductor cables (NYY/NYCY equivalent) feature high conductivity, stable mechanical strength, smaller voltage drop, suitable for high‑load equipment, short‑distance industrial installations and high‑reliability critical circuits. Typical uses: industrial workshops, commercial building main power supply, fire‑safety circuits, equipment internal power feed.
Choose Aluminum‑Alloy Cable for Cost‑Sensitive Long‑Distance Distribution
Aluminum‑alloy cables (AA‑8000 alloy cable) deliver obvious cost advantages for long‑distance power‑distribution. It is widely used for urban grid transformation, large residential‑district power supply. Please calculate voltage drop and short‑circuit capacity in advance.
Choose Armoured Cable for Direct‑Burial / Mechanical‑Risk Environment
Select SWA/STA armoured construction (SWA armoured cable) when cables are directly buried underground, passing through road zones or exposed to mechanical‑damage risk. Armour provides mechanical protection against external impact. For corrosive soil environment, additional anti‑corrosion sheath shall be specified.
Choose LSZH / Fire‑Resistant Cable for Public‑Safety‑Critical Projects
For tunnels, metro, high‑rise buildings, hospitals and underground public spaces, specify LSZH (LS0H / HFFR) flame‑retardant or fire‑resistant CI circuit integrity cables to avoid toxic smoke diffusion during fire accident. Confirm required flame‑retardant grade (ZA/ZB/ZC) and fire‑survival time.
Choose Medium‑Voltage XLPE Cable for Substation & Renewable‑Energy Grid‑Connection
MV XLPE cables (11kV/33kV distribution cable) are the mainstream solution for power transmission between substations and wind‑photovoltaic power‑station grid‑connection. Confirm rated voltage, cross‑section, single‑core / three‑core structure and short‑circuit withstand requirement.
Understanding Key Cable Parameters
Correct parameter selection is equally important as choosing cable model.
Conductor Class
Class1: Solid single‑wire conductor, for fixed installation
Class2: Stranded compacted conductor, widely used for power‑cable fixed installation
Class5 / Class6: Flexible stranded conductor, for moving‑equipment connections (flexible cable)
Voltage Rating
0.6/1kV for most low‑voltage distribution (600/1000V mains); 6/10kV‑26/35kV for medium‑voltage transmission (11kV, 33kV MV). Voltage rating must match system operating voltage.
Armouring
SWA: Steel‑wire armoured, for underground direct‑burial, anti‑impact (Steel Wire Armour)
STA: Steel‑tape armoured, anti‑crush (Steel Tape Armour)
AWA: Aluminum‑wire armoured, anti‑magnetic eddy‑current for single‑core MV cables (Aluminium Wire Armour)
Unarmoured: For cable‑tray / conduit indoor installation without mechanical‑damage risk
Important: Not every armouring type is applicable for single‑core medium‑voltage cables; magnetic‑armour selection rules must be followed.

Material selection and production of power cables
Good materials and technology contribute to the success of good cables
The selection of high-quality conductor material (oxygen free copper) for power cables has the following characteristics:
High conductivity: Oxygen free copper has a high conductivity and low resistivity, which can ensure the stability and reliability of current transmission.
Good mechanical properties: Oxygen free copper has good plasticity and ductility, making it easy to process into various specifications of cable cores and cables.
Corrosion and oxidation resistance: Oxygen free copper is not easily corroded and oxidized, ensuring long-term stable operation of cables.
Good welding performance: The welding performance of oxygen free copper is excellent, which can meet the needs of various cable connections and installations.
Choose high-quality insulation materials for power cables based on different cables
Common cable insulation materials include polyethylene (PE), cross-linked polyethylene (XLPE), polyvinyl chloride (PVC), fluoroplastics, etc.
Polyethylene and cross-linked polyethylene have good electrical properties, heat resistance, and chemical stability, and are widely used for insulation of low-voltage and medium high voltage cables; Polyvinyl chloride has good electrical and processing properties, but has low heat resistance and is prone to aging.
It is commonly used for insulation in general household appliances and building electrical systems; Fluoroplastics have excellent heat resistance and chemical corrosion resistance, and are widely used for cable insulation in high temperature and chemical corrosion environments.
Precision equipment and advanced technology are necessary conditions for producing power cables
Drawing: The drawing process is to draw the raw material of the conductor into a single wire with the desired cross-sectional shape and size through a drawing machine. According to different needs, it can be done through single wire drawing and twisted drawing methods.
Twisting: The twisting process involves interweaving multiple single wires in a specified direction to form a wire core that meets the flexibility requirements. This step can improve the flexibility and overall integrity of wires and cables.
Wrapping: The wrapping process involves passing the pre made wire core through an extruder, allowing the insulation layer to wrap around the conductive wire core. According to different performance requirements for wires and cables, specialized equipment can be used to wrap different materials on the outside of the conductor, such as rubber, plastic, lead, aluminum, etc.
FAQ
Purchasing cables, many customers are concerned about the following issues
Q:What power‑cable types can you supply?
A:We supply low‑voltage (0.6/1kV, NYY type) and medium‑voltage (6‑35kV,11kV/33kV) power cables: copper‑conductor, aluminum‑alloy (AA‑8000) conductor, SWA armoured /unarmoured, LSZH (LS0H) low‑smoke zero‑halogen, flame‑retardant, fire‑resistant CI and overhead insulated ABC aerial power cables.
Q:What is the difference between armoured and unarmoured power cable?
A:Armoured cables adopt steel‑tape /steel‑wire armour layer (SWA/STA) to resist external mechanical impact, suitable for direct‑burial underground. Unarmoured cables are for indoor cable‑tray /conduit installation without mechanical‑damage risk. Single‑core medium‑voltage cables have special‑armour selection rules to avoid eddy‑current heating.
Q:Copper vs aluminum‑alloy power cable, how to choose?
A:Copper cable (NYY/NYCY) has higher conductivity, smaller voltage drop, compact outer‑diameter, higher total cost. Aluminum‑alloy cable (AA‑8000) reduces project material cost, lighter weight, suitable for long‑distance distribution grid reconstruction. Please calculate voltage drop and short‑circuit capacity before selecting aluminum‑alloy cables.
Q:When should I choose LSZH low‑smoke zero‑halogen power cable?
A:LSZH (LS0H / HFFR) cables produce low‑smoke and non‑toxic‑halogen gas under burning. It is mandatory for tunnels, metro stations, high‑rise public‑buildings and underground‑public‑space projects. Ordinary PVC cables cannot replace LS0H for these safety‑critical scenarios.
Q:Can you provide fire‑resistant power‑cable with circuit‑integrity performance?
A:Yes. We supply fire‑resistant CI circuit integrity power cables built with mica‑tape fire‑barrier layer. You shall specify required fire‑survival time and corresponding test standard for your project.
Q:Can you customize cable drum/reel length and sheath printing?
A:Yes. We can produce cables to your requested drum/reel‑cut length, and print cable model, voltage, meter‑mark and customer logo on outer sheath.
Q:What international standards can your power‑cables comply with?
A:Our cables can be manufactured complying with IEC 60502‑1, IEC 60502‑2, GB/T 12706, BS 5467, VDE and other international standards subject to cable construction.
