Product Overview:
The 3×70mm² 11kV Power Cable is specially designed for reliable power transmission in medium voltage (MV) networks. With high-performance copper conductors, XLPE insulation, and galvanized steel tape armour, this cable ensures excellent electrical performance, mechanical strength, and long service life. It is widely used in industrial, infrastructure, and energy distribution projects.
Applications:
Underground Power Distribution
Renewable Energy Projects
Industrial Facilities
Infrastructure Projects
Utility Substation Connections
Harsh Environments
High Safety & Durability: XLPE insulation provides high dielectric strength and thermal resistance. The steel tape armour protects against mechanical damage during and after installation.
Excellent Environmental Resistance: UV-resistant and waterproof outer sheath ensures reliable performance in harsh environments.
Low Maintenance: Long operational life reduces downtime and maintenance costs.
Flexible Customization: Available in various cross-sections and lengths; options for LSZH, fire-resistant, or flame-retardant versions.
Compliance with International Standards: Fully compliant with IEC and BS specifications.
What voltage rating does this cable support?
This cable is rated for 11kV medium voltage systems, and typically conforms to 12/20(24)kV class depending on installation standards. It is used for power transmission in substations, industrial plants, and utility grids.
What is the construction of this cable?
Conductor: Stranded copper (Class 2)
Insulation: XLPE
Screen: Semi-conductive layer with copper tape or wire screen
Inner sheath: PVC
Armour: Steel Tape Armour (STA)
Outer sheath: Black PVC or PE, UV-resistant
What are the advantages of XLPE insulation?
XLPE offers excellent thermal resistance (90°C continuous), high current capacity, strong mechanical and chemical resistance, and low dielectric loss.
What is STA and why is it used?
Steel Tape Armour provides mechanical protection against impact or rodent damage. It is suitable for direct burial and underground trench installations, but not for applications requiring cable flexibility.
Is the cable flame retardant or fire-resistant?
The cable is flame retardant according to IEC 60332-1 or IEC 60332-3. If fire resistance is required (maintaining circuit integrity during fire), a different cable with fire-resistant layers (such as mica tape) should be used.
What standards does this cable comply with?
IEC 60502-2
VDE 0276-620
IEC 60228 (conductors)
IEC 60332 (flame testing)
RoHS and ISO 9001 manufacturing systems
Can this cable be used outdoors or underground?
Yes. The cable is UV-resistant, suitable for outdoor installations, and designed for direct burial or conduit use.
Do you offer customized sizes or lengths?
Yes. Cross sections from 3×25mm² to 3×300mm² are available. Custom lengths, core color codes, and sheath printings can be provided upon request.
