Wires are an indispensable material in the manufacturing of integrated domestic wastewater treatment equipment, and their quality directly affects the performance of the equipment. To ensure product quality, strict inspections of wire quality are necessary. Below, our editor introduces the methods for judging the quality of wires in integrated domestic wastewater treatment equipment.

1. Homeowners should ask vendors to cut a section of the wire to inspect the copper core material. The copper core should be bright, soft, and have good tensile strength. Conversely, a wire with poor luster and blackening, or one that has been oxidized, may indicate a substandard product. Poor-quality products have dark, hard copper, which is a recycled mixed copper with poor conductivity and can pose a hazard to integrated domestic wastewater treatment equipment.

2. Look at the length and price. How do you determine the length of a wire? Some manufacturers deceive by making the outer sheath thick, making it hard for the average person to spot the trick. However, everyone can count the number of turns and then multiply it by the radius of the entire spool to roughly estimate its length.

When selecting wires, pay attention to the surface of the wire. Good quality wires are usually smooth and flat, with no damage to the insulation sheath, clear markings, and a non-greasy feel when touched. Lastly, when purchasing wires, ensure that the conductor diameter matches the specifications on the certificate of compliance. A wire with a conductor cross-section that is too small can easily overheat and cause a short circuit.

4. Ensure the wire packaging label includes a birth certificate number. When inspecting the wire's interior, always check if the outer plastic sheath is bright and dense, and whether it can ignite a flame when extinguished with a lighter. Poor-quality products typically use recycled plastic, which is dull and loose, and can easily catch fire, potentially causing accidents.
