加长型10kV热缩三芯交联聚乙烯电缆中间接头的连接方法
摘要：
本发明公开了一种加长型10kV热缩三芯交联聚乙烯电缆中间接头的连接方法，一、准备工作。二、剥外护套及铠装层。三、剥内护套及填充物。四、制作加长型中间接头。五、剥除铜屏蔽层及外半导电层。六、固定应力管。七、套入管材。八、压接各相线连接管。九、缠绕半导电带。十、包绕填充胶。十一、固定半导电绝缘复合管。十二、包绕防水胶。十三、包绕半导电带。十四、安装铜屏蔽网及地线。十五、固定密封护套管。10kV热缩三芯交联聚乙烯电缆线路受力破坏后，一般断头距离都在10～200mm范围内，按本发明将200mm以下断头一律断为200mm断头，每芯用一个自制的加长型中间接头进行一次性连接，连接后电气性能完全达到技术标准要求。
摘要（英）：

The invention discloses a connecting method of a lengthened 10kV thermal shrinkable three-core cross-linked polyethylene cable intermediate joint. The method comprises the following steps of: I, preparing; II, peeling an outer jacket and an armor layer; III, peeling an inner jacket and a filler; IV, manufacturing a lengthened intermediate joint; V, peeling a copper shielding layer and an outer semiconducting layer; VI, fixing a stress tube; VII, sleeving a tubular product; VIII, pressing each phase line connecting tube; IX, winding a semiconducting belt; X, wrapping filling glue; XI, fixing a semiconducting insulating compound tube; XII, wrapping water-proof glue; XIII, wrapping a semiconducting belt; XIV, installing a copper shielding screen and a ground wire; and XV, fixing a sealed protecting tube. After a 10kV thermal shrinkable three-core cross-linked polyethylene cable circuit is damaged by pressing, the general end breaking distance is 10-200 millimeters, broken ends below 200 millimeters are broken into broken ends of 200 millimeters, each core is connected at one time by using a home-made lengthened intermediate joint, and the electric performance fully meets the technical standard requirement.
