详细介绍

性能特点

Performance Characteristics

电表线夹适用于电缆与电表箱的“T”型分支接续,适合各种运行环境,体积小、运行安全可靠,电性能优越,适用电压1kV及以下,适用主线16-300mm2,分支线 4-50mm2。

Electric Meter Wire clamp is used to connect the T-shape branches between cables and the meter box.Due to its small size, excellent conductivity and reliable performance, the wire clamp is suitable underall sorts of environment. It is suitable for voltage lower than 1kV, main cables with section between 16 to300mm2 and branch cables with section between 4 to50mm2


1. 电气连接采用铰接和自锁功能,是产品完美结合,还大大减轻了劳动强度,在安装和拆卸时都不会损伤导线的导体,能重复使用,与导线等同寿命。

Electrical connection has articulate and self-lockingfunctions, which perfectly fits this product。 The wireclamp also greatly alleviates the intensity of wear, itwill also not damage the cables during installation anduninstallation。 The wire clamp can be repetitively used and have equal longevity as the cable。


2.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。

The body of Electric Meter Wire clamp is made from aluminum alloy of high tensile strength, high elasticity and high conductivity. Its unique design allows it to have high tensile strength and great elasticity. It can maintain sufficient contact between the wire clamp and cable under all sorts of adverse environment,which enhances stability and eliminates the need for maintenance.


3.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 Electric Meter Wire clamps uses advanced materials and composition and is fire-proof, anti-UV rays and can withstand weather

changes.

4.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。

The Wire clamps have low resistance and can greatly withstand changes in temperature. 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.


5.电表线夹零部件采用铝合金和不锈钢等不导磁金属,不会产生磁耗,属于节能金具,并且抗氧化腐蚀性能高

The aluminum alloy of high tensile strength and stainless steel materials the wire clamps are made deters hysteresis loss, corrosion as well as oxidation,resulting in long life of the wire clamps.


6.绝缘电缆上“随遇而安”装,工作效力高。

The Wire clamps can be installed on insulted cables with ease and is highly efficient.

电表线夹安装步骤

Installation Instructions


1、选型

Decide the model

根据实际使用的主、支导线规格选定所需的电表线夹,

范围对应适合;

decide the model in accordance to the specification ofthe main and branch cables.


2、准备

Preparatio

穿戴好必要的安全防护工具,剥主导线的绝缘层,剥开宽度应略大于电表线夹宽度,长度不超过电表线夹宽度 10mm 为宜,再剥分支导线端部的绝缘层,剥开长度为 25 ~ 30mm;

wear necessary protective gear. Peel off the insulatedlayer of the main cable, the width peeled off should be slightly greater than the width of the wire clamp but should not exceed the width of the wire clamp by 10mm. Then, peel 25 to 30 mm off the insulated layerof the branch cable.


3、连接安装

Installation

拧松电表线夹螺母至最大范围,先扣入主线剥开部位,再把分支导线按出线口标识插入正确位置,用手拧紧螺母,检查无误后再用扳手拧紧,直至电表线夹与导线稳定牢固;

loosen the screw nut of the wire clamp to maximum, first place in the peeled main cable, then place the branchcable according to the signs. Screw the screw nut until the wire clamp and cable are tightly connected。



4、绝缘罩安装

Installation of insulated cap

打开绝缘罩,把已安装的电表线夹套上绝缘罩,方向对应,扣上绝缘罩扣子,未使用的那个出线口用悬挂在绝缘罩上塞子堵住;

Open the insulated cap and place onto the wire clamp then shut the cap. Stuff the used opening using theplug on the insulated cap.


5、铅封保护

Led protection

用万用表检测或通电运行确认无故障后,在绝缘罩的下端 2 个小孔处安装铅封,用以防止任意打开或私接

电线,即完成安装。

After determining the device is operating smoothly,install led seals in the 2 holes beneath the insulated cap to prevent accidental opening of the cap or wire attachment。
