        絕緣穿刺線夾 Insulated Piercing Wire Clamp

        詳細介紹

        性能特點

        Performance Characteristics


        絕緣穿刺線夾主要適用于架空絕緣導線的接續、分支連接和接地保護,適用電壓等級為 10kV 及以下,其主要性能和特點:

        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.安裝簡便。運用穿刺的原理,使接觸刀片穿透導線的絕緣層后刺入導體,安裝時無需剝去導線的絕緣層,只要按規定位置在線夾中放入主線和支線,用套筒扳手均勻擰斷力矩螺母即可。

        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.壽命持久。安裝線夾的導線損傷微小,結構仍然密封,導體不會裸露而氧化、腐蝕,因此不影響架空絕緣導線的正常使用壽命,而且產品材料均為進口或國內優選,強度高、耐老化,使用壽命遠高于架空絕緣導線,性價比高。

        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.電阻小,溫升低。特制力矩螺栓確保安裝時恒定的穿刺壓力,使線夾與導線達到良好的電氣接觸而不過分損傷導線,簡化了安裝難度,接觸齒片材料為紫銅表面鍍銀,導電性能極佳。


        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.結構密封、絕緣性高。線夾內部采用絕緣導熱絕緣油脂填充,安裝后完全達到封閉、絕緣效果,提高穿刺線夾絕緣強度和安全性,保證線夾在惡劣的自然環境中長期可靠地運行。

        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.免維護。線夾的鎖緊裝置上設有碟型墊片,采用高強度彈簧鋼制作,安裝時通過變形能儲存一部分的能量,在線夾受外界氣候影響熱脹冷縮時提供補償,使接觸齒片跟導體始終有恒定的壓力,保證足夠的電氣接觸面積。

        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.線夾適用范圍廣??蛇m用于銅鋁導線、異徑導線的支接、等徑導線的對接,并適用于銅鋁絕緣導線的過

        渡連接。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  


        由于絕緣穿刺線夾是屬于“電纜附件”還是“電力金具”還沒有最后定論,國內對穿刺線夾的命名方式尚未統一,如早期的JBC、JC和近期的JJC等。進口的穿刺線夾則多以各自企業的產品編號為準。



        1.絕緣穿刺線夾命名方式為:

        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.

        絕緣穿刺接地防雷線夾

        Insulated Piercing Gounded anit-Lightening Wire Clamp


        絕緣穿刺防雷線夾的主要技術性能指標

        The Key Performance Indicators OfInsulted Piercing Wire Clamp


        絕緣導線防雷驗電接地線夾是為防止 10kV 架空絕緣導線遭雷擊斷線而研制開發的新型產品。本產品是集防雷、驗電、接地三位一體的多功能架空絕緣線路防護金具;而且安裝不用剝除絕緣導線,也不需要更換原有的絕緣子及橫擔,僅加裝本產品既可。安裝方便快捷,大大提高現場工作效率。本產品經武漢高壓研究院,上海電氣輸配電試驗中心檢測,試驗通過。

        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.


        本產品特點及基礎原理是將該產品安裝在架空絕緣導線遭雷擊閃絡的多發部位,(理論研究及實踐證明此多發部位經常是在電桿上導線的某固定部位),當雷電過電壓超過一定數量值,會在防雷線夾的高壓電極和低壓電極之間的空氣間隙中閃絡,形成短路通道。接續的工頻短路電流電弧的弧根固定在放電環上燃燒,從而保護架空絕緣導線的熔化斷線。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.
