高压电缆阻燃聚乙烯外护套浸水条件下电气绝缘性能试验研究

Experimental Study on Electrical Insulation Performance of Flame Retardant Polyethylene Sheath of High Voltage Cable under Water Immersion Conditions

对阻燃聚乙烯外护套在浸水条件下的电气特性进行了研究。通过试验五种不同配方的阻燃护套材料试片和电线的长期浸水绝缘性能,筛选出能够在长期浸水条件下具有较好电气特性的阻燃添加剂,为进一步研发提供了方向。

The electrical characteristics of flame retardant polyethylene sheath under immersion conditions were stud ied in this paper.Five kinds of flame retardant sheath materials with different formulations were tested for their long term immersion insulation properties.The flame retardant additives with good electrical properties under long term im mersion conditions were screened out,which provided a direction for further research and development.
