详细介绍

    性能特点   

    Performance Characteristics 

    力矩节能线夹是非承力接续金具,结构新颖独特,制造工艺精美,适用于架空铝绞线或钢芯铝绞线的接续 及分支连接。 

Torque energy saving wire clamp is a non-strength-bearing connecting hardware, with brand new structureand delicate manufacturing。 It is suitable for directconnection and branch connection of overheadaluminum cables or aluminium cables steel reinforced(ACSR)。



 (1)安装简便,采用特定的扭力螺母控制安装力矩,安装时只需拧断扭力螺母即可,排除了安装过程中的人为因素,保证线夹与导体之间恒定的电气接触。

The installation is convenient, with special screw nutcontrolling moment. To install, just twist off the nut.This can avoid the human factors in the installationprocess and guarantee stable electric connectionbetween clamp and conductor. 

 

 (2)采用优质弹簧钢制作的碟型垫片取代传统的弹簧垫圈,抗疲劳性能强,弹性持久,能在安装时储存一部分能量,弥补因气候环境热胀冷缩时线夹对导线的压紧力。 

The traditional spring washer is replaced by plate-shape washer, which is made by high quality springsteel, with good fatigue resistance and lasting elasticity。It can store some energy during installation, and offsetthe pressure to wires made by thermal expansion in different climatic environments。 

 

 (3)主体材料采用高强度、高弹性、高导电的铝合金,独特的设计结构使产品具有优越的强度和弹性功能,在各种恶劣的环境中线夹都能紧握导线,保证线夹与导线的充分接触,提高了运行稳定性,免去日常维护。 

Aluminum alloy with high strength, high elasticity andhigh conductivity is used as main material. Its uniquestructure gives outstanding strength and elasticity.It can hold the wire firmly even in various harshenvironments, keeping adequate connection between clamp and wire, and promoting working stability toreduce daily maintenance.

 (4)适用范围广,通用性好,能用于同径或异径导线连接,跨径大选型方便,仅几个规格就覆盖了所有导线的接续组合,特别便于抢修或夜间施工。

It can be widely used in various connections betweencables with same or different radius。 With wide rangeof allowed radius difference, it is convenient to choosethe types since several types of clamps can cover all thecombinations of different wires, especially convenientfor emergent fixing or night work。


 (5)主体铝合金表面镀锡,由于锡是软金属,安装受力时锡会变形,从而增大导线与线夹的接触面,提高了线夹的导电能力。

Tinplating is used on the surface of main bodyaluminum。 Since tin is soft metal, it will deform and be reshaped during installation, thus increasing thearea between wire and clamp, therefore promoting the

conductivity of the clamp。


 

 (6)螺栓、碟型垫片表面进行了达克罗处理,钢铁件盐雾腐蚀试验达 500 小时以上,确保产品的正常使用寿命,能在沿海或潮湿的气候环境中长期不腐蚀、不生锈。

The surfaces of bolt and plate-shape washer are treated  with DACROMET treatment. Over 500 hours of saltspray corruption tests guarantee the length of normal  service life. It can stay non-corroded and unrusted inhumid environment for a long time. 


 (7)电阻小,温升低,热循环性能满足国标GB/T2314。3 电力金具试验方法的要求,一般情况下安装一个线夹就能满足电性能。

The electric resistance is small and the temperatureincrease is low. Its heat recycle ability pass the

requirement of international GB/T 2314.3 test.Normally, one clamp is enough for ideal electrical  performance.

 

 (8)力矩节能线夹螺栓和扭力螺母的螺纹配合十分精确,手拧螺纹时进退顺畅,省力。

The torque energy saving wire clamp can accuratelyfit the thread of screw nut. So the operation is smoothand easy.

安装方法

Installation Procedure


 (1)首先选择适合导线截面的力矩节能线夹,在安装前准备:绝缘导线应剥去绝缘层,剥绝缘层的长度略长于线夹,裸线则应清洁导线表面污垢;

Choose the Torque energy saving wire clamp thatfits the sectionof wire. Before installation: removethe insulation layer。 Make the length of removedinsulation layer a little longer than the length of wireclamp (clean the surface of wire if it has no insulationlayer。)


 (2)拧松线夹的螺栓,分别将主线和支线扣入线槽,再用手拧紧扭力螺母,确保导线的位置正确无误;

loosen the bolt. Respectively, lock the main line andbranch lines into the slot, and then twist the screw nut。Make sure the position of wire is correct。


 (3)然后用套筒扳手拧紧,直至拧断扭力螺母,即完成安装;

Tighten the screw nut with socket spanner until the nut breaks. The installation is done.


 (4)如果架空绝缘导线上安装线夹,最后应配上绝缘罩。

If stall wire clamp on overhead insulating wire, put on the insulating cover.


注: 

(1)禁止使用开口扳手或活动扳手安装力矩节能线夹;

Comment: Don’t use open spanner or monkey spanner to install moment sketchy wire clamp

(2)力矩节能线夹属一次性线夹,重复使用时请更换新的扭力螺母。

Torque energy saving wire clamp is disposable wireclamp。 Please use new screw nuts when the wire clampis reused.
