How to Check the Quality of Electrical Wires: A Guide to Ensuring Safety and Reliability

When it comes to electrical wiring, quality is paramount. Poor-quality wires can lead to electrical failures, fires, and other hazards. Therefore, it’s essential to know how to check the quality of electrical wires before purchasing them for your home, office, or industrial use. In this guide, we will discuss various methods to assess the quality of electrical wires, including the FRLS test, counting the right number of strands, and measuring the thickness of the strands.

Understanding FRLS Wires

FRLS (Fire Retardant Low Smoke) wires are designed to reduce the spread of fire and produce minimal smoke in the event of a fire. Here’s how to ensure your wires meet FRLS standards:

• FRLS Test: This test ensures that the wires are fire retardant and produce low smoke. Ensure that the wires you purchase have been tested for these properties and comply with relevant standards like IS 694:2010.
• Certification: Check for certifications and compliance marks on the wire packaging, which indicate that the wires meet safety standards.

Counting the Number of Strands

The number of strands in a wire affects its flexibility and current-carrying capacity. Here’s how to check:

• Visual Inspection: Carefully strip a small section of the insulation and count the number of copper strands. Compare this with the specifications mentioned on the packaging.
• Specifications: For example, a 0.75 SQ MM wire should have 24 strands of 0.2mm diameter each. Ensure the actual count matches these specifications.

Measuring the Thickness of Strands

The thickness (gauge) of each strand in a wire determines its current-carrying capacity and overall performance. Here’s how to measure it:

• Micrometer: Use a micrometer to measure the diameter of individual strands. Ensure the measurements align with the specifications provided by the manufacturer.
• Consistency: Check multiple strands from different sections of the wire to ensure uniform thickness throughout.

Additional Quality Checks

• Copper Purity: High-quality wires use pure electrolytic grade copper, which has better conductivity and durability. Look for purity certifications or perform a resistivity test.
• Insulation Quality: Inspect the insulation for uniformity, flexibility, and durability. Poor-quality insulation can lead to short circuits and fire hazards.
• Brand Reputation: Purchase wires from reputed brands like Polycab, RR Kabel, Novawires etc. which adhere to stringent quality standards and testing protocols.
