《GB/T 12972.2-2008矿用橡套软电缆 第2部分：额定电压1.9/3.3kV及以下采煤机软电缆》由TC213（全国电线电缆标准化技术委员会）归口，主管部门为中国电器工业协会。
GB/T 12972《矿用橡套软电缆》分为10个部分,本部分为GB/T 12972的第2部分。本部分代替GB 12972.2-1991《矿用橡套软电缆 第2部分：额定电压0.66／1.14KV及以下采煤机软电缆》。B/T 12972的本部分规定了额定电压1.9/3.3kV及以下采煤机电缆产品品种、技术要求、试验方法和检验规则。本部分适用于额定电压U0/U为1.9/3.3kV及以下采煤机及类似设备用的铜芯橡皮绝缘橡皮护套软电缆。本部分应与GB/T 12972.1共同使用。本部分与GB 12972.2-1991相比主要变化如下：
―――名称更改为“额定电压1.9／3.3KV 及以下采煤机软电缆”；
―――增加了额定电压UCP1.9／3.3KV 采煤机软电缆（本版的表１）；
―――额定电压Uo／U为0.66／1.14KV 电缆规格由导体截面35mm2～95mm2 增加到35mm2～120mm2（1991年版的表2ｂ；本版的表3）；
―――删除了原规格表中控制线芯参数（1991年版的表2ａ和2ｂ）；
―――增加了“控制线芯芯数不少于3芯、线芯标称截面不小于2.5mm2”内容（本版的6.4）；
―――删除了XJ-00A 型橡皮内容（1991年版的5.3.1和5.3.2）；
―――调整提高电缆在20℃时绝缘电阻最小值（1991年版5.1，本版的7.1）；
―――电缆燃烧试验由GB/T 18380.1《电缆在火焰条件下的燃烧试验 第1部分：单根绝缘电线或电缆的垂直燃烧试验方法》代替GB/T 12666.2《单根电线电缆垂直燃烧试验方法》（1991年版的表4；本版的7.2）。
