In medium-voltage power systems, cable insulation materials are a core element ensuring stable power transmission and safe equipment operation. Their performance requirements are stringent and diverse, directly impacting cable lifespan and overall system reliability.
High insulation resistance is a fundamental requirement. Medium-voltage cables must withstand thousands of volts or even higher, necessitating insulation materials with extremely high resistance values to effectively prevent current leakage, ensure efficient power transmission, and avoid safety accidents caused by leakage.
Excellent heat resistance is equally crucial. Medium-voltage cables generate heat during operation, especially under prolonged high loads. The insulation material must withstand high temperatures without softening, deforming, or degrading, ensuring stable operation even in high-temperature environments.
Good mechanical properties are indispensable. Cables are subjected to various mechanical stresses during laying, installation, and operation, such as tension, bending, and compression. The insulation material must possess sufficient tensile and compressive strength and flexibility to resist these mechanical damages and ensure the integrity of the cable structure.
Chemical corrosion resistance is also an important consideration. Medium-voltage cables may be laid in various complex environments, such as chemical industrial areas and humid locations. The insulation material must be able to resist the erosion of chemicals such as oil, acids, alkalis, and solvents to prevent a decline in insulation performance due to chemical corrosion.
Aging resistance is equally important. Under long-term electrical, thermal, and mechanical stress, the insulation material must maintain stable performance and not easily age or crack, ensuring reliable operation of the cable throughout its entire service life.
