NXL 系列楔形耐张线夹及绝缘罩

NXL series aluminium alloy strain clamp(wedge type) and insulation cover A

用途 /Application
耐张线夹
NXL 系列楔型耐张线夹适用于 20kV 及以下配电线路中，将架空绝缘铝导线或裸铝导线固定在转角或终端耐张杆的绝缘子上，从而将架空导线固定或拉紧，
绝缘罩与耐张线夹配套使用，起绝缘防护作用。
NXL series strain clamp(wedge type)is suitable for distribution wire up to 20kV,fixing the aerial insulation aluminium conductor or naked aluminium
conductor on the rotate angle or insulator of terminal strain pole,and then fixing and tighting the aerial conductor,insulation cover and strain clamp are
used together.It's action is insulation protection.

结构特点 /Structure Feature

◆ 选用非磁性高强度抗氧化铝合金材料，无磁滞损耗； ◆ Choose the unmagnetic character high-intersity oxidate-resistance aluminium alloy. No
waste electric energy.
◆ 楔块锁紧结构，安装简便可靠；
◆ Wedged-locked structure，easy installation.
◆ 圆弧大面积抱紧，导线不易蠕变、握力大。
◆ An are embraces the most part， conductor can't change， large grip strength.

绝缘罩性能特点 /Insulation Cover Performance Feature
◆ 1-10kV 工频耐压：≥ 18kV，保压 1 分钟不击穿； ◆ 1-10kV power frequency voltage: ≥ 18kV, dwell 1 minute without breakdown;
◆ 20kV 工频耐压：≥ 30kV，保压 1 分钟不击穿； ◆ 20kV power frequency withstand voltage: ≥ 30kV, dwell 1 minute without breakdown;
