用途Application

  JBL、JBT、JB-TL系列异型并沟线夹适用于架空电力线路中导线的非承受力接续与分支，与绝缘罩配套使用起防护绝缘作用。

  JBL，JBT，JB-TL Specific forms parallel groove clamp is suitable for unendure force splicing and branch on the aerial wire ,being used with insulation cover . It’s action is insulation protection.

 

●结构特点Structure feature

 1、选用抗氧化铝合金材料

 2、齿形结构，接触电阻小，接续可靠

 3、部件连体，安装时不会掉件

 4、圆弧大面积抱紧，导线不易蠕变

 1、Select oxidze-resistance aluminium alloy.

 2、Teeth-shape structure ,touch with lowly resistance, reliable splicing.

 3、All parts connected with each other , it can’t tlose parts during installation

 4、An are embrace the most part ,conductor can’t change

绝缘罩性能特点Insulation cover performance feature

 1、工频耐压：≥18kV保压1分钟不击穿

 2、绝缘电阻：>1.0×1014Ω

 3、环境温度：-30℃~90℃

 4、耐气侯性能：经人工气侯老化试验1008小时后性能良好

 1、Withstand voltage: ≥18kV keep voltage one minute not break down

 2、Insulation resistance: >1.0×1014Ω

 3、Environments temperature: -30℃~90℃

 4、Weather proof performance:  have good performan  after 1008 hours artifical l climate aging test.
