Material selection and testing requirements:
- EN50264: This standard deals with cross-linked polyethylene insulation materials. When selecting and testing insulating materials, attention should be paid to their heat resistance, aging resistance, electrical properties, etc. to ensure the stability of the cable in long-term use and under different environmental conditions.
- EN50306: For high voltage cables, special attention should be paid to the dielectric strength and partial discharge characteristics of the insulating materials, etc. These properties directly affect the safety and reliability of cables in high voltage environments.
- EN50382: For silicone-coated glass fiber cloth insulated cables, attention should be paid to the heat resistance and mechanical strength of the silicone coating, as well as the durability and electrical properties of the glass fiber cloth.
Testing and certification standards:
- EN50264: It shall be ensured that the specified insulation resistance test, fire resistance test and electrical performance test are carried out and in strict accordance with the test methods required by the standard.
- EN50306: Partial discharge testing of HV cables is critical but can sometimes be overlooked. Partial discharges are a common precursor to faults in HV cables and therefore must be properly tested and evaluated.
- EN50382: Be aware of the special requirements in the test methods, including testing of electrical characteristics under high temperature conditions, to ensure the reliability of cables in extreme environments.
