3.8/6.6kV Single Core Copper MV Power Cable

3.8/6.6kV single core copper MV power cable is made of stranded compacted circular copper, which has excellent conductivity, making it the preferred material for high-performance electrical cables. The stranded and compacted structure increases flexibility and reduces the overall diameter of the conductor, improving current-carrying capacity while maintaining mechanical strength. The compacted design also ensures better contact between strands, reducing energy loss and improving overall efficiency during power transmission.

Min. installation temperature: 0 degree

Operating temperature: -25 degree to +90 degree

Emergency operating temperature: 105 degree

Max. Short Circuit Temperature: 250 degree

Copper 3.8/6.6kV MV power cable are suitable for large infrastructure power distribution, such as factory power distribution, underground system power distribution, and transmit power from substations to various users. MV power cable are moisture-proof and corrosion-resistant, which can ensure long-term stable operation and avoid failures caused by the external environment.

Min. installation temperature: 0 degree

Operating temperature: -25 degree to +90 degree

Emergency operating temperature: 105 degree

(max. operation of 36hrs, at 3 periods for 12 consecutive months use)

Max. Short Circuit Temperature: 250 degree

• Nominal Voltage: 3.8/6.6 (7.2) kV

• Conductor: Stranded Compacted Circular Copper conductor as per AS/NZS 1125

• Conductor Screen: Extruded Semi-conductive compound

• Insulation Screen: Extruded Strippable Semi-conductive compound

• Metallic Insulation Screen: Copper Wire Screen + helically applied copper tape (E/F current capacity – Based on requirement)

• Termite Protection: Polyamide (Nylon -12) (optional)

(Alternative Sheath: PVC+HDPE Composite Sheath or PVC + Nylon + HDPE

(composite sheath with anti-termite properties) or LSZH Outer sheath and parameters will change accordingly)

AS/NZS1429.1 MV power cable has been extensively tested to prove its reliability under different conditions, such as temperature fluctuations, humid environments, etc., to ensure the long-term stable operation of the cable in harsh environments, reduce safety risks such as electrical failures and fire, and protect the safety of users and equipment.

Q:What are the main application scenarios of medium-voltage cables?

A: Medium-voltage cables are widely used in industries, power infrastructure, urban distribution networks, wind farms, photovoltaic power stations and other scenarios that require reliable power transmission.

Q: What is the difference between medium-voltage cables and high-voltage cables?

A: The voltage level of MV cables is lower than that of high-voltage cables. High-voltage cables are used for power transmission above 35kV, while medium-voltage cables are used for power distribution systems with lower voltages.

Q:What is the difference between aluminum-core medium-voltage cables and copper-core medium-voltage cables?

A:Aluminum-core cables are lighter and less expensive, but their conductivity is slightly inferior to that of copper-core cables. Copper-core cables have high conductivity and are suitable for applications with high current density requirements.
