The advantages of standard wires can be elaborated from multiple dimensions such as safety, performance, durability, compliance and cost. The following is a more detailed analysis of the key points:
1. Safety: Comprehensive protection from materials to craftsmanship
High purity of conductors: Made of oxygen-free copper with a resistance of over 99.99%, the resistance is 20%-30% lower than that of non-standard wires. It generates less heat during operation, reducing the risk of short circuits and fires.
The insulation layer meets the standards: The thickness and withstand voltage strength comply with the standards. Flame-retardant cables self-extinguish when burning and produce low smoke toxicity
2.. Electrical Performance: Precisely match the load requirements
True current-carrying capacity: For instance, a 2.5mm² standard copper wire has a safe current-carrying capacity of 16-25A and can be used to drive 3000-5000W electrical appliances. Non-standard wires, due to the "reduction" of the conductor cross-sectional area (actually only 1.5mm²) and the falsely marked current-carrying capacity, are prone to cause electrical appliances to trip due to overload.
3. Durability: Adaptable to complex environments and long-term use
Anti-aging material: Antioxidant is added to the insulation layer, resistant to ultraviolet rays and acid and alkali corrosion, with an outdoor service life of over 20 years. Recycled plastic used for non-standard wires may crack and powderize within 1-2 years.
High mechanical strength: The conductors are tightly twisted together, and they are not easily damaged when bent or stretched during construction, while the insulation layer of non-standard products is prone to tearing.
4. Comprehensive Cost: More economical for long-term use
Although the unit price of standard wires is 30% to 50% higher than that of non-standard ones, they have a longer lifespan, fewer malfunctions and do not need to be replaced frequently. Non-standard wires are prone to aging and short circuits, which may cause damage to electrical appliances or fires, and the hidden costs are even higher (such as repair and claim expenses).
