一、产品概述:
SYC系列上元C型线夹属于我公司专利产品之一。上元C型线夹主要用于架空配电线路中10kV架空绝缘导线、铝绞线、钢芯铝绞线、
非承受力位置上T型接续或跳线用。本上元C型线夹采用导电性能良好的高强度特制铝合金制造而成,结构采用合理的C型两块主楔块
组成,当主楔块受外力的作用下,将导线压在线夹主体和两块分楔块之间。由于线夹的主体采用特制的C型设计原理,当导线热胀冷
缩时,线夹的主体本身具有的弹性性能,始终保持线夹与导线间持久恒定的接触压力。它随着外界环境及负载条件的变化,而接触压
力不变,使其满足了在接续连接中的最佳性能要求。
二、C型线夹安装说明
C型线夹为非承力型电力连接金具,不能用作承力金具;只能使用于导线的连接,跳线,“T”接及变压器引下线。线夹适用电压等级:10kV、35kV、110kV、220kV、380kV、可以铝-铝、铜-铜、铁-铁的连接。无须包铝包带。
1、确定型号:仔细核对导线与线夹上所标一致,如:SYC-822 LGJ185-LJ120/95,LGJ95表示为:LGJ185对LJ(TJ)120或
LGJ185对LJ(TJ)95或LGJ185对LGJ95的连接。如图(1)
2、确定大小线:因线夹在设计中考虑满足不同线径的配合,铰接块两边的内弧面有不同的尺寸,大弧面配合大导线;小弧面配合小导线。规定:母块为大(主)线,公块为小(支)线,把铰接块拿出,使其成拱状(两铰块转成一定角度)。如图(2)
3、放好导线和螺栓:把导线放入“C”件线槽中,根据大小线放入成弓形向外)。从“C”件背面插入螺栓,使螺栓位于铰接块顶部
的中间位,用扳手拧紧螺栓。如图(3、4)4、确认已装好:在拧紧螺栓时,在最后几个螺牙应有明显受力感,把铰接块压平,顶住“C”件即可。“C”件应有微微变形。如图(5)
注:安装完后用手拉或扳两导线,看两导线是否已被压紧。
5、拆卸:松开螺栓,在铰接与“C”件间插入螺丝批,用力向上撬,使铰接块向上拱即可。如图(6)
三、塑料外壳的特点
1、工频耐压:≥18kV保压1分钟不击穿;
2、绝缘电阻:≥1.0x10 Ω;
3、环境温度:-30℃~90℃;
4、耐气候性能:经人工气候老化试验1008小时后性能良好;
5、抗拉强度:≥200MPa;
