In terms of mechanical strength, some competitors’ products have lower compressive strength, which may lead to a higher risk of damage under heavy loads or harsh environmental conditions.
For electrical resistance, a few competitors can't achieve the 500 - 1000 kV/cm range, resulting in more current leakage and potential impacts on system stability.
Regarding fault detection, not all competitors have the convenient zero - value self - breaking feature, making defect discovery more time - consuming and difficult during inspections.
In environmental durability, some rival products show more significant performance degradation under prolonged exposure to weather, UV, or pollution, requiring more frequent maintenance.
For self - cleaning, competitors with rougher surfaces may accumulate contaminants faster, reducing insulating capabilities and increasing maintenance work.
