The installation of dense busbar trunking can be directly connected from the transformer to the low-voltage distribution cabinet, or directly connected from the low-voltage cabinet to the distribution system as a distribution main line. Replacing the traditional use of power cables, dense bus ducts can be used in high current places such as buildings and workshops where cables were previously used. Dense busbar trunking is a type of conductor that can replace traditional cables for transmitting electricity. It consists of copper bars and an outer shell, with each copper bar having an insulating medium and each copper bar tightly connected to form a three-phase four wire or three-phase five wire conductor. The outer shell is generally grounded.

The connection terminals of the busbar trunking system adopt butt double clamping, multi piece stacking, and tin plated conductor connection. The force is transmitted to each butterfly washer through high-strength torque bolts to ensure even force distribution, good conductor contact surface, fast and convenient installation, low joint temperature rise, overall continuity, and superior conductor performance. The connecting terminal insulation partitions are made of polycarbonate high-strength insulation extruded parts. High strength characteristic torque bolts can achieve a pressure of over 21000 Newtons on the busbar pressure plate. The bus duct is made of three-phase five wire system and three-phase four wire system, with tin plated bus bars on the surface of the conductor overlap, and the shell is made of steel refrigeration casting material.

The busbar combines the advantages of air and dense busbars, which can withstand strong electric forces and have good heat dissipation capabilities, greatly improving its load capacity. In addition, with the design of the peripheral structure and the use of molding machines, it has extraordinary support strength, which can ensure that the central part of the 6m busbar can withstand a pressure of 70 kilograms, and the deflection does not exceed 15mm, solving the problem of being unable to support lifting during large-span installation. The bus duct is a high current transmission system with a design current of 1250A-4000A. It adopts air type insulation and has a heat resistance level of B (130 ℃). It has the characteristics of excellent structural strength and smooth lines; And it absorbs the design ideas and high-quality requirements of German predecessors, with a protection level of up to IP54.
