【摘要】 本文对MPG母排绝缘热收缩管抗自然老化性能进行了研究 ,实验结果表明:在本次实验期间 ,材料的体积电阻率、介电常数、击穿强度、断裂强度、断裂伸长率等性能均变化不大 ,材料的微观结构也无明显变化。各项性能指标完全符合规定要求更多还原

【Abstract】 In this paper,the anti_natural ageing properties of the MPG brs bar insrlation heat shrinlable tubes were studyed.The test results indicated that the volume resistivity、 dielectric constant、 breskdown strength、 bresking strength and breaking elongation had no large change during this test.And the microstructure of this material had no notable change, too. The every properies is accord with the demands.更多还原
