1. Performance parameters and requirements for dense busbar trunking
1.1 Busbar structure type: dense busbar; Rated working voltage (Ue): 1000V; Rated insulation voltage (Ui): 1000V;
1.2 Protection level: IP66, rated frequency: 50HZ. It has the characteristic of preventing flame spread; Fire resistance characteristics in building structures, fire resistance time: 180min
1.3 The bus duct must ensure long-term stable operation at 100% rated current. The specifications of the bus duct are 400 A、630A、800A、1000A、 1250A 、1600 A、2000 A 、2500A 、3150A、 4000A 、 5000A、6300A
2. Conductor material and composition.
2.1 The phase conductor of the bus duct adopts high conductivity TMY electrical hard copper rolled by T2 electrolytic copper, which meets the national standard. The purity requirement of the copper busbar is ≥ 99.95%, and the DC resistivity at 20 ℃ is ≤ 0.01708 Ω mm2/m. The entire busbar is tinned.
The cover plate and side plate of the busbar enclosure are assembled by rolling high-quality and heat dissipating aluminum profiles. The inner busbar is wrapped with polyester film with good insulation performance, which can ensure that the product's edge performance meets the specified requirements and avoid the problem of large temperature rise caused by wrapping ordinary insulation materials. The shell of this series of bus ducts is made of aluminum profiles with excellent conductivity, which can be used as PE bars for three-phase five wire systems. The busbars are closely arranged between each other and closely adhered to the side panels, which can effectively reduce temperature rise. The dedicated connector insulation board is used to connect the various units of the busbar. This series of busbar slots has the characteristics of excellent structural strength and convenient and fast connection. Used for power transmission and distribution systems in various industries, it has the advantages of excellent structural strength and convenient and fast connection and plugging. The connection points of each unit in the bus duct are sealed with sealant to ensure a protection level of IP66.
3. Insulation material
3.1 The insulation medium of the busbar is made of flame-retardant materials, with insulation and heat resistance levels reaching Class B. It can withstand high temperatures of 150 ℃ and low temperatures of -60 ℃, and does not release toxic gases in the event of a fire. DuPont film from the United States is used.
3.2 The insulation material adopts the process of covering each phase of copper bars as a whole, and the insulation aging life reaches more than 30 years.
3.3 It can maintain its flexibility and dielectric strength without aging in an environment temperature of -5 ℃~40 ℃ for a long time.
4. Shell material:
To ensure the strength, rigidity, and heat dissipation effect of the busbar trunking system, the aluminum alloy shell side plate of the busbar trunking system adopts a shell with a heat dissipation device.
4.2 It adopts a fully enclosed form, with a compact structure, flexible configuration, good dynamic and thermal stability, and strong resistance to internal and external impact.
4.3 The outer surface of the trunking should be treated with anodizing to achieve good anti-corrosion effect.

Basic description of system components
Unlike traditional intensive products, the MK-I intensive busbar system adopts the Henrob riveting technology from the UK, and the overall structure of the shell adopts rivet riveting, with a high degree of automation production. By using hydraulic transmission, a large and uniform pressure can be obtained, which greatly improves the overall strength of the bus duct, and has good sealing effect and anti-seepage function. It has a high protection level, excellent electrical continuity, and a clean and beautiful appearance.
