Three Core 1.9/3.6kV Aluminum MV Power Cable

During the production process, three core aluminum MV power cable undergoes rigorous tests to verify its ability to withstand various conditions. These tests ensure that the cable can effectively enhance its safety and reliability in actual applications.

Application

Three core 1.9/3.6kV aluminum MV power cable is widely used in medium capacity distribution networks that balance cost-effectiveness and reliability. Its 1.9/3.6kV rated voltage falls within the low-to-medium voltage range, making it ideal for local power distribution, power feeders, and medium-sized industrial equipment. It also serves lighting systems, pumping stations, HVAC systems, and small to medium production lines that don't require ultra-high transmission capacity.

Feature

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

• Conductor Screen: Extruded Semi-conductive compound

• Insulation: XLPE

• Insulation Screen: Extruded Semi-conductive compound

• Longitudinal Water blocking : Water blocking tape above and below copper screen (Optional)

• Metallic Insulation Screen: Copper Wire Screen + helically applied copper tape

• binder tape / sheath over assembled cores

• Metallic Sheath: Lead Alloy (optional)

• Outer Sheath: Extruded Polyvinyl Chloride, Colour: Black

• Insect attack Protection: Polyamide Nylon (optional)

(Alternative Sheath: PVC + HDPE Outer Sheath or LSZH Outer sheath and parameters will change accordingly)

Certification

MV power cables have obtained SAA certification, with certification numbers: SAA242046 and SAA250307 (available on the certification website). SAA certified cables meet stringent Australian and international standards for conductor purity, insulation thickness, flame retardancy, and other aspects. The certification process is more than just a formal review; it undergoes a series of tests for electrical performance, mechanical strength, and long-term durability. The cables are guaranteed to operate stably and safely in high-voltage environments, eliminating the risk of cutting corners. Key components undergo rigorous verification, ensuring they are truly high-quality, proven cables.

FAQ

Q: What applications are 3 core aluminum MV cables mainly used for?

A: 3 core aluminum MV power cables can be mainly used in power distribution systems. In the power distribution networks of cities and towns, MV power cables are used as distribution lines to connect substations and user terminals. They can effectively transmit medium voltage power to meet the needs of different users.

Q: Are power cables suitable for use in marine environment?

A: Power cables can be used in marine environments, but there are special requirements for cables. For example, waterproof and moisture-proof properties. In marine environments, cables need to have extremely high waterproof properties. Corrosion resistance. The salt content in marine environments is high, which is corrosive to cable metal materials. Mechanical strength. To prevent cables from being affected by water currents, waves or collisions in marine environments, the sheath and structure of the cable need to have good mechanical strength to withstand these physical pressures. UV resistance. Cables are partially exposed to the air on offshore platforms or offshore facilities, and need to have UV resistance to avoid damage to the cable sheath by sunlight. Anti-biological erosion. Organisms in the marine environment (such as marine microorganisms, shellfish, etc.) may attach to the surface of the cable. Anti-biological attachment components are added to the cable sheath to maintain its normal operation. Temperature and pressure adaptability. Since the temperature and pressure on the seabed may be relatively extreme, the cable needs to use materials that can withstand large temperature differences and high water pressure.

Q: Can aluminum cable be used to power electric motors?

A: Aluminum conductor cables can be used to power motors, but it is necessary to ensure that the cable specifications meet the operating requirements of the motor. For example, voltage level, the voltage level of the motor should match the rated voltage of the cable. Current carrying capacity, the current carrying capacity of the cable must be sufficient to meet the needs of the motor. Conductor material, aluminum conductors are relatively light and have lower costs than copper conductors. Although the conductivity of aluminum is slightly lower than that of copper, it can also meet the power supply needs of the motor if the cross-sectional area of the cable is appropriately increased. Insulation performance, the insulation layer material of the cable must be resistant to high temperature and moisture and have good durability. Short-circuit and starting current, the current of the motor at startup is much higher than the normal operating current, so the cable must be able to withstand a short-term high current shock.
