Test Method for Establishing Volume Resistivity Compatibility of Water Blocking Components With Extruded Semiconducting Shield Materials
用挤压半导体屏蔽材料确定阻水部件体积电阻率兼容性的试验方法
ICEA T-32-645-2012 (R2017) provides procedures for establishing volume resistivity compatibility of water blocking
components with extruded semiconducting shields utilized in MV, HV or EHV power cables. The
compatibility test is designed to verify that the electrical properties of a semiconducting material used as a
conductor or insulation shield are not adversely affected when exposed to a water blocking component.
These water blocking components can be incorporated in a conductor, over a conductor, over an insulation
shield, or around a metallic shield or concentric neutral. It describes a test method of demonstrating that
the volume resistivity and volume resistivity stability remain within their specified limits when a
semiconducting material is exposed to a water blocking component at the emergency operating
temperature of the cable.
