Therefore, it is more Screw Terminal Blocks Manufacturers to be careful when laying cables. As long as the qualified product is unscrewed on the torque nut, it means that the wire core has been reliably connected to the piercing connecting piece. Especially for low-capacity systems, the use of uniform current grade piercing clamps as the cable branch method will reduce the material cost more significantly, coupled with easy installation, save on-site construction labor, and the total construction cost will be greatly reduced.

2 Laying, installation and quality control Lay the main cable and branch cables (wires) in place according to the traditional cable laying method, and install the piercing clamp after the cable is basically fixed.

It is impossible to suspend and fix a large number of cables in the shaft. The single-core production process is simpler with more cores and the price is lower. Prefabricated branch cables are divided into single-core and multi-core. investment. The production cycle is long. You only need to visually check whether the torque nut is broken and the position of the wire during installation. After installation, it cannot be seen from the appearance whether the main branch cable connector has been reliably connected. After testing,

the contact resistance value and line insulation resistance meet the requirements of the construction specification, and the temperature rise of the joint part is normal when the load is applied. When laying, the branch cable and the main cable move together, and you must always pay attention to the protection of the branch cable.
