标准范围

IEC 62895:2017规定了额定电压不超过320 kV（含320 kV）的固定陆地安装用输电电力电缆系统、挤压绝缘电缆及其附件的测试方法和要求。在本标准的范围内，“挤出绝缘材料”是指通过挤出热塑性（例如聚乙烯）或交联（例如交联聚乙烯、乙丙橡胶等）材料制造的绝缘材料。绝缘材料可以是未填充的或填充的(例如用矿物或碳)。这些要求适用于单芯电缆及其附件、气体绝缘系统的室外和终端、接头和通常安装和运行条件下的不对称接头，但不适用于特殊电缆及其附件，如海底电缆，对其可能需要修改标准试验或可能需要设计特殊试验条件。

IEC 62895:2017 specifies test methods and requirements for transmission power cable systems, cables with extruded insulation and their accessories for fixed land installations, for rated voltages up to and including 320 kV.
Within the scope of this standard “extruded insulation” means insulation manufactured by extrusion of either thermoplastic (e.g. polyethylene) or crosslinked (e.g. crosslinked polyethylene, ethylene propylene rubber, etc.) material. The insulation material may be either unfilled or filled (e.g. with mineral or carbon).
The requirements apply to single-core cables in combination with their accessories, outdoor and terminations for gas insulated systems, joints, and asymmetric joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables, for which modifications to the standard tests may be necessary or special test conditions may need to be devised.
