Structure and Performance Analysis of LDPE Special for Cable Insulation
In this paper,low-density polyethylene(LDPE)2220H is mainly studied,which has some special properties as a common insulating material,these properties are mainly reflected in the molecular chain structure and volume resistivity.According to the research results,LDPE A has different parameters compared with LDPE B,including the relative molecular weight,while the relative molecular mass distribution is roughly the same;the crystallinity and melting temperature of the former one are higher than those of the latter one,and the volume resistivity of the latter one is lower when a high temperature is set;the former one has higher characteristic breakdown strength;the electrical properties of the two materials are mainly affected by the crystallization properties and other factors.
