1、矿用电缆与热力管道平行安装时应保持2m的距离,交叉时应保持0。5m。 1, the mine cable should be kept at a distance of 2m from the parallel installation of thermal power pipelines, and 0。5m should be maintained at the time of crossing。 2、电缆与其它管道平行或交叉安装时均要保持0。5m的距离。 2, the cable should be kept at a distance of 0。5m when it is parallel or cross installed with other pipelines。 3、电缆直埋安装时,1-35kV电缆直埋深度应不小于0。7m。 3。 When the cable is buried directly, the depth of 1-35kV cable shall not be less than 0。7m。 4、10kV及以下电缆平行安装时相互净距不小于0。1m,10-35kV不小于0。25m,交叉时距离不小于0。5m。 4。 When the cables are installed parallel to 10kV and below, the distance between them is not less than 0。1M, 10-35kV is not less than 0。25m, and the distance between crossover time is not less than 0。5m。 5、电缆的最小弯曲半径,多芯电缆不得低于15D,单芯电缆不得低于20D(D为电缆外径)。 5, the minimum bending radius of the cable, multi core cable should not be less than 15D, single core cable must not be less than 20D (D is the outer diameter of cable)。 6、6kv及以上电缆接头。 6, 6kV and above cable joints。 A。 安装电缆终端头时,必须剥除半导电屏蔽层,操作时不得损伤绝缘,应避免刀痕及凹凸不平的情况,必要时要用砂纸磨平;屏蔽端部应平整,并要把石墨层(碳粒)清除干净。 A。 installation cable terminal head, must be stripped of semi conductive shielding layer, operation should not damage the insulation, should avoid knife marks and uneven condition, when necessary, use sand paper grinding, shielding end should be smooth, and clean the graphite layer (carbon)。 B。 塑料绝缘电缆端头铜屏蔽和钢铠必须良好接地,对短线路也应遵循这项原则,避免三相不平衡运行时钢铠端部产生感应电动势,甚至"打火"及燃烧护套等事故。接地引出线要采用镀锡编织铜线,和电缆铜带连接时应用烙铁锡焊,不宜用喷灯封焊,以免烧损绝缘。 The copper shield and steel armor of the B。 plastic insulated cable must be well grounded, and the short line should follow this principle to avoid the induction electromotive force at the end of the steel armour at the unbalanced operation of the three-phase, even the accidents of "fire" and the burning sheath。 The grounding lead wire shall be tin plated braided copper wire and soldered iron soldering when connected with the cable copper belt。 It is not suitable to use the torch to seal the weld so as to avoid burning the insulation。 C。 三相铜屏蔽应分别与地线相连,注意屏蔽接地线和钢铠接地线应分别引出,相互绝缘,焊接地线的位置应尽量靠下。 The C。 three phase copper shielding should be connected to the ground line respectively。 It is noted that the shielded grounding wire and the steel armored ground line should be separately elicited and insulated from each other。 The position of the welded ground wire should be as far as possible。
