16mm Square Single Core Flexible Pure Copper Cable | PVC Insulated 450/750V
The Flexible Wire 16mm Square is a high-grade electrical cable engineered for versatility and high conductivity. Constructed with 99.9% pure annealed copper, this 16mm single core flexible cable utilizes a Class-5 stranded design, making it incredibly easy to maneuver through tight conduits and complex panel layouts. Its robust PVC insulation is designed to withstand the physical stresses of moving applications and provides excellent resistance to moisture and abrasion.
At Enon Traders, we highly recommend this 16mm cable for residential solar inverters and solar batteries setups (typically 3kW to 5kW systems). It is the ideal choice for connecting battery series or as a main DC lead where standard rigid cables are too difficult to install. For a complete and safe installation, ensure your solar panels are wired with correctly sized conduits like our flexible pipe 1 inch.

Benefits
- Reduces Installation Time: The “soft” nature of the wire makes it much faster to pull through pipes than standard 7/44 or 7/64 cables.
- Prevents Overheating: High purity copper ensures the cable stays cool even under continuous load, protecting your equipment.
- Space Efficient: Higher current capacity in a smaller overall diameter compared to lower-grade cables.
- Long Service Life: Designed for a functional lifespan of 30+ years in protected environments.
Applications
- Battery Interconnections: Perfect for 12V, 24V, and 48V battery banks in UPS and Solar systems.
- Inverter DC Input: Connecting the battery bank to the DC terminals of the inverter.
- Internal Switchgear: Wiring inside electrical control panels and distribution boards.
- Industrial Machinery: Providing power to portable tools, motors, and lighting rigs.
- Earthing: Used as a flexible grounding wire for sensitive electronic racks.
