1. The authors estimated high-field currents, impulse- and DC-breakdown, space charge distribution by PEA method, and treeing phenomena in order to apply new low-density polyethylene (LDPE) using methallocene catalyst to the insulating material for power cable. It is found that LDPE using methallocene catalyst has more excellent insulating properties than a conventional LDPE using high-pressure method which is widely used as an insulating material for power cable. In addition, the former has a higher DC tree initiation voltage and shows higher suppression of tree growth than the latter.2. The authors estimated high-field current, space charge distribution by LIPP and PEA method for modified high-density polyethylene films with different thickness. For all specimens, a negative space charge is observed to be accumulated near a cathode. When the thickness of film increases, both the high-field current of specimen and the density of the negative space charge decrease. The decrease is thought to be explained by the morphology of film near surface.

1.作者估计了高场电流，脉冲和直流击穿，空间电荷分布的PEA方法，和树枝化现象，以应用新的低密度聚乙烯（LDPE）使用茂金属催化剂的电力电缆绝缘材料。发现使用茂金属催化剂的LDPE比广泛用作电力电缆绝缘材料的使用高压法的常规LDPE具有更优异的绝缘性能。此外，前者具有更高的直流树起始电压，表现出更强的抑制树生长.用LIPP和PEA方法计算了不同厚度的改性高密度聚乙烯薄膜的高场电流和空间电荷分布。对于所有的标本，观察到负空间电荷附近的阴极积累。随着薄膜厚度的增加，样品的高场电流和负空间电荷密度均减小。这种下降被认为是由近表面的膜的形态来解释。
