详细介绍

性能特点

Performance Characteristics


绝缘穿刺线夹主要适用于架空绝缘导线的接续、分支连接和接地保护,适用电压等级为 10kV 及以下,其主要性能和特点:

Insulated Piercing Wire clamp is mainly used for branch connection and ground protection of overhead insulated cable。 It is applicable to voltage level no higher than 10kV。


1.安装简便。运用穿刺的原理,使接触刀片穿透导线的绝缘层后刺入导体,安装时无需剥去导线的绝缘层,只要按规定位置在线夹中放入主线和支线,用套筒扳手均匀拧断力矩螺母即可。

Insulated Piercing Wire clamp is easy to install. It uses a blade to puncture the insulated layer of the cable into

the conductor, thus eliminating the need to peel off the insulated layer when installing。 Simply place the main

and branch lines into certain locations and then use a wrench to twist off the torque nut.

2.寿命持久。安装线夹的导线损伤微小,结构仍然密封,导体不会裸露而氧化、腐蚀,因此不影响架空绝缘导线的正常使用寿命,而且产品材料均为进口或国内优选,强度高、耐老化,使用寿命远高于架空绝缘导线,性价比高。

Insulated Piercing Wire clamp has a long life. The wire clamp deals little damage to the wire when installing, the structure of the wire is still intact so that the conductor will not be exposed to oxidation or corrosion; thus the longevity of the insulated wire is not affected. Moreover, the raw materials are all imported or the best domestic selection, they are strong and does not wear, thus the longevity of the wire clamp is much greater than overhead insulated cables.


3.电阻小,温升低。特制力矩螺栓确保安装时恒定的穿刺压力,使线夹与导线达到良好的电气接触而不过分损伤导线,简化了安装难度,接触齿片材料为紫铜表面镀银,导电性能极佳。


Insulated Piercing Wire clamp has little contact resistance and low temperature increase. The specially made moment bolt guarantees constant puncture pressure which enables to wire clamp to have a good electric contact without excessive conductor damage. The moment bolt also simplifies the installation process, with the contact chain rings made from copper with silvering, the conductivity of the wire clamp is excellent.


4.结构密封、绝缘性高。线夹内部采用绝缘导热绝缘油脂填充,安装后完全达到封闭、绝缘效果,提高穿刺线夹绝缘强度和安全性,保证线夹在恶劣的自然环境中长期可靠地运行。

Insulated Piercing Wire clamp has a sealed structure with great insulation。 The internal part of the wire clamp is filled with insulating heat-conductive grease, which seals the wire clamp and improves the insulation and safety of the wire clamp, ensuring smooth operation and endurance in adverse environment。


5.免维护。线夹的锁紧装置上设有碟型垫片,采用高强度弹簧钢制作,安装时通过变形能储存一部分的能量,在线夹受外界气候影响热胀冷缩时提供补偿,使接触齿片跟导体始终有恒定的压力,保证足够的电气接触面积。

Insulated Piercing Wire clamp does not need maintenance。 The locking device of the wire clamp has a disc shape gasket, which is made from strong spring copper。 Energy is store by deformation during installation and can be released to compensated for thermal expansion and contraction。 The contact chain rings apply a constant pressure onto the conductor, ensuring sufficient electrical contact area。


6.线夹适用范围广。可适用于铜铝导线、异径导线的支接、等径导线的对接,并适用于铜铝绝缘导线的过

渡连接。Insulated Piercing Wire clamp has a wide range ofusage。 It is applicable to branch connection of copper

and aluminum conductor, hetero-diametric conductorand iso-diametric conductor. It is also applicable to

transition branch connection of copper and aluminum insulated cable。

命名方式

Naming Of  Electric Meter Wire Clamp  


由于绝缘穿刺线夹是属于“电缆附件”还是“电力金具”还没有最后定论,国内对穿刺线夹的命名方式尚未统一,如早期的JBC、JC和近期的JJC等。进口的穿刺线夹则多以各自企业的产品编号为准。



1.绝缘穿刺线夹命名方式为:

Naming of Insulated Piercing Wire clamp


Because whether Insulated Piercing Wire clamp is "Cable accessories" or "Electrical Fitting" is still under debate, the naming of Insulated Piercing Wire clamp has yet to be unified, such as the early "JBC" "JC" or the recent "JJC". Imported Insulated Piercing Wire clamp is usually numbered by corporations.

Insulated Piercing Gounded anit-Lightening Wire Clamp


绝缘穿刺防雷线夹的主要技术性能指标

The Key Performance Indicators OfInsulted Piercing Wire Clamp


绝缘导线防雷验电接地线夹是为防止 10kV 架空绝缘导线遭雷击断线而研制开发的新型产品。本产品是集防雷、验电、接地三位一体的多功能架空绝缘线路防护金具;而且安装不用剥除绝缘导线,也不需要更换原有的绝缘子及横担,仅加装本产品既可。安装方便快捷,大大提高现场工作效率。本产品经武汉高压研究院,上海电气输配电试验中心检测,试验通过。

Type aerial insulation conductor anti-lightening and power acceptance earthing clamp is the new type product researched and developed for preventing 10kV aerial insulation conductor from line breaking when lightening happens。The product is the multi-functional protection hardware fittings with aerial insulation line and it integrates three functions of anti-lightening,power acceptance and earthing;moreover,the stripping of insulation

conductor is not necessary during installation and the original insulator and cross arm will not be changed,and the product is the only thing that shall be installed。The installation is convenient and rapid,which enhance the working efficiency greatly。 The product passes the test and experiment of  Wuhan High Voltage Research Institute。


本产品特点及基础原理是将该产品安装在架空绝缘导线遭雷击闪络的多发部位,(理论研究及实践证明此多发部位经常是在电杆上导线的某固定部位),当雷电过电压超过一定数量值,会在防雷线夹的高压电极和低压电极之间的空气间隙中闪络,形成短路通道。接续的工频短路电流电弧的弧根固定在放电环上燃烧,从而保护架空绝缘导线的熔化断线。The feature and basic principle of the product is to install the product in the part where lighting flashover

occurs to the aerial insulation conductor easily,(the theoretical research and practice prove that such part

is often shown as a certain part of the conductor on the pole)。When the overvoltage of the lightening surpasses a certain value,flashover will be formed in the air gap between the high voltage electrode and low voltage electrode of the anti-lightening hardware fittings。The arc root of the continued power frequency short-circuit current will be fixed to the discharge to burn in order to protect the aerial insulation conduct from melting and line breaking。
