Regarding the selection of pre insulated sleeve withstand voltage level, first of all, the lowest voltage model that can meet the conditions should be determined based on the purchaser's use environment and objects. Secondly, each pre insulated junction sleeve model has an average voltage value and an individual voltage value. So when choosing a insulated joint sleeve withstand voltage level, try to choose a model that is one level higher than the rated voltage. In layman's terms, according to the actual working voltage environment of the covered object, choose a pre-insulated casing that is greater than the actual voltage environment of the covered object to ensure safety of use.
