Insulating sleeves are widely used in household appliances and are key components ensuring their safe and stable operation. In large household appliances such as air conditioners, refrigerators, and washing machines, they protect the internal wiring harnesses from long-term vibration and friction damage. In kitchen appliances such as microwave ovens, rice cookers, and induction cookers, they utilize their excellent high-temperature resistance to provide a reliable insulating barrier for wires in high-temperature environments. Zhengtong Insulation provides high-temperature and wear-resistant insulation material solutions, effectively ensuring the electrical safety and durability of various household appliances during long-term use.
