详细介绍

性能特点

Performance Characteristics

C 型线夹属于非承力接续金具,适用于架空裸导线和架空绝缘电缆的接续及分支连接,适用于绝缘架空电缆的接地装置连接等。

C-shape Wire clamp is a non-load-bearing continual fitting and is suitable for connecting overhead cables and transformers.


1。C 型线夹主体采用高强度铝合金制造,导电性能良好,高弹性。并根据不同规格的导线,设计有特定形状的导线沟槽或相应的铰接楔块,即使在导线热胀冷缩时,亦能始终保持导线与线夹间持久而恒定的接触压力。

The body of C-shape Wire clamp is made from aluminum alloy of high tensile strength. C-shape Transformer Wire clamp has excellent conductivity and is highly elastic. The wire clamps have cable trenches of matching shapes or specific hinged wedges according to different specifications of cables, which allows the constant pressure to be maintained between the wire clamps and the cables.


2. 过载能力强,接触电阻小,由于线夹对导线形成稳定的压力负荷,且涂有抗腐蚀、抗氧化、憎水性的导电性能很强的电力复合脂,确保了优良的导电性能,热循环性能满足国标 GB/T 2314.3 电力金具试验方法的要求。

Because a constant pressure load is maintained between the wire clamps and the cables, the C-shape Wire clamps have little contact resistance and can greatly withstand overload as well as changes in temperature. Moreover, the anticorrosive, antioxidant, hydrophobic electric power compound grease ensures excellent conductivity. The thermal cycling property of the wire clamps also matches the international GB/T 2314.3 standard of general technical requirements for electric power fittings.


3. 安装简便,安装只需拧紧一枚螺栓,普通工具即可安装。

C-shape Wire clamps are installation friendly。 They can be installed using simple tools and only requirescrewing a bolt.


4. 节能环保,线夹材质采用高强度铝合金和不锈钢制造,无磁滞损耗,抗腐蚀、氧化。

C-shape Wire clamps are environmentally friendly, the aluminum alloy of high tensile strength and stainless steel materials they are made deters hysteresis loss,corrosion as well as oxidation, resulting in long life of the wire clamps.


5. 绝缘外罩使用国内先进新材料和配方,阻燃,抗紫外线,耐候性好

The insulated exterior of the C-shape Wire clamps usesadvanced materials and composition and is fire-proof,anti-UV rays and can withstand weather changes.

安装说明

Installation Instructions


C型线夹为非承力型电力连接金具,不能用作承力金具;只能使用于导线的电性能连接、跳线、“T”接及变压器引下线。任何电压等级均可使用,只要导线截面适合安装范围,对于架空绝缘电缆,在安装 C 型线夹的位置应剥除绝缘层。

C-shape Wire clamp is a non-load-bearing electrical connection fitting and cannot be used to bear load,

it can only be use to connect cables, jumper, T-shape connections and deflectors for transformers. As long as

the size of the cable is within range, the wire clamp can be installed to any level of voltage。 For overhead insulatedcables, the insulated layer of the cable should be peeled off on the connection part.


1.确定型号:按被接续的主支线截面规格和线型在选型表中找出对应的线夹型号,选型时把主线线型和规格当成横坐标,支线的线型和规格当成纵坐标,如LGJ-185 对 LGJ15O 分支连接,对应的线夹型号为CT-821;

Decide the model: decide the model of wire clamp touse according to the specification of the model and the section of the main and branch cables to be connected in reference to the table of models。 When using the table, set the specification and model of the main cable and branch cable as the X and Y axis accordingly and cross reference them to attain the model of wire clamp. For example, cross reference models LGJ-185 with LGJ-150 and the model of wire clamp should be CTK- 821.


2. 确定主支线:因线夹在设计中考虑满足不同线径的配合,铰接块两边的内弧面有不同的尺寸,大弧面配合主线;小弧面配合支线。规定:母块为大(主)线,公块为小 ( 支 ) 线,把铰接块拿出,使其成拱状(两拱块转成一定角度);

Determine the position of the branch lines: Because the wire clamp is designed to fit cables of different diameters, the intradoses of the two sides of the hinged block have different sizes with the large intrados for the main cable and the small one for the branch cable。 The female block is for the main cable and the male block is for the branch cable. Take out the hinged block, so that they from an arch (the two hinged blocks can be spun to form an angle).


3. 安装:把导线扣入“C”线形槽中,根据主支线放入成拱型的位于铰接块顶部的中间位,装上螺栓及平垫、螺母,先用手拧紧后再用扳手拧紧螺栓;

Installation: put the cable into the C-shaped trench and place the branch line in the middle of the arch-shape hinged block. Install the bolt, flat pad and screw nut then use your hand and later a wrench to screw the bolt tight. 


4. 螺栓拧至明显受力感,导线与“C”块及铰接块紧密接触,“C”块背部并有微微变形即完成安装。

When the bolt is screwed tight, the cable, the C-shapeblock and the hinged block are tightly connected. The installation is complete when slight deformation canbe observed on the back of the C-shaped block。


5. 对于绝缘电缆安装前应剥去导线绝缘层,在完成安装后,应加盖线夹绝缘罩。

After installation is completed, an insulated cap shouldbe added onto the wire clamp.


拆卸:松开螺栓,在铰接块与“C”块间插入一字螺丝刀,用力上撬使铰接块向上拱,即可分离导线与线夹。

Uninstallation: loosen the bolt on the C-shape block,insert a flathead screwdriver between the C-shape

block and the hinged block, apply force so that the hinged block moves outwards to detach the cable and

the wire clamp.
