Finolex 10 Sq Mm Armored Cable Recommended for Home Upgrades

Upgrading your home's electrical system can be daunting, especially when navigating complex cable specifications. Finolex, a reputable cable manufacturer, offers a reliable solution with its 10 square millimeter 4-core armored copper cable. Here’s a breakdown of its key features to help you make an informed decision.

The cable features high-quality copper conductors, known for superior conductivity and low resistance. Compared to aluminum alternatives, copper cables offer higher current-carrying capacity, ensuring efficiency and safety in power transmission.

The "10 square millimeter" designation refers to the cross-sectional area of each copper core, which determines its current-carrying capacity. This size is ideal for home mainlines, supporting high-power appliances like air conditioners and water heaters. The four independent cores are typically used in three-phase systems or single-phase setups with live, neutral, ground, and control wires.

The cable incorporates a metal armor layer for mechanical protection against impacts and crushing. Each copper core is insulated with 0.7mm PVC, while dual PVC sheaths (0.3mm inner and 1.4mm outer) enhance durability and weather resistance.

Key electrical properties include:

• Maximum DC resistance: 1.83 ohms
• Maximum AC resistance: 2.34 ohms
• Reactance at 50Hz: ~0.0837 ohms/km
• Capacitance: ~0.31 mFd/Krr

These parameters ensure stable performance in AC circuits with minimal energy loss.

With an outer diameter of 21.8mm, the cable is easy to install. Its 73-amp rated current capacity provides ample headroom for residential applications when properly sized with safety margins.

The black outer sheath aids identification. Professional installation by licensed electricians is mandatory to comply with electrical safety standards.

Finolex's armored copper cable combines robust construction with reliable performance, making it a prudent choice for home electrical upgrades. Proper selection and installation ensure long-term safety and efficiency in your power distribution system.
