1. Reducing the withstand voltage grade of the cable: If the thickness of the insulation layer is insufficient, its withstand voltage capacity will decline, which may lead to breakdown at normal working voltage and cause damage to the equipment
Damage or personal injury.
Second, accelerate cable aging: The resistance to temperature changes, humidity, chemical corrosion, etc. will decrease, thereby reducing the service life of the cable.
Iii. Safety Hazards: During construction and maintenance, if the insulation layer is too thin, it may cause the cable temperature to be too high. Long-term high-temperature operation will accelerate the aging of the cable
It may even cause serious consequences such as fires.
Fourth, increase the difficulty of laying: During the cable laying process, if the insulation layer is too thick, it will increase the outer diameter of the cable. Conversely, if the insulation layer is too thin, the cable may be prone to damage when subjected to external forces.
