2500A dense busbar trunkingBus shell configuration
The LCMC series bus duct adopts a reasonable "sandwich" phase line tightly stacked structure design, which makes the bus duct more compact in appearance, smaller in volume, and enhances the dynamic and thermal stability of the bus system. It has the advantages of low impedance and voltage reduction, and eliminates the formation of the "chimney effect" of the bus duct in case of fire. It can be applied to large-span installation on construction sites.
2500A dense busbar trunkingBus shell configuration
The shell is composed of reinforced molded aluminum magnesium alloy profiles for electrical use or a mixture of molded aluminum alloy integral side panel profiles for electrical use and cold drawn steel cover panel profiles. This set of shell is lightweight, fully enclosed, and windproof, with both ultra-high bending strength and good corrosion resistance, as well as excellent heat dissipation and grounding properties. Aluminum magnesium alloy shell is corrosion-resistant and has a service life of over 50 years.
1. The integral aluminum alloy side plate structure wraps the conductor inside the metal side plate, preventing the penetration of water vapor and harmful dust, and achieving a true IP54 protection level for the busbar as a whole;
2The special aluminum shell forms a non-magnetic choke coil, which can reduce the transmission of eddy currents between high current busbars, reduce the passage of harmonic currents in the main busbar, reduce the heating phenomenon caused by the above reasons, reduce the voltage drop of long-distance transmission, and significantly enhance the current carrying capacity of the busbar;
3The aluminum side plate structure that tightly contacts the conductor as a whole can directly transmit and dissipate heat from multiple surfaces such as the side plate and cover plate, improving the heat dissipation capacity of the busbar system and increasing the current carrying capacity;
4The integral grounding system is formed within the shell range, and users can choose this integral aluminum shell with>50% phase line capacity as the grounding conductor. In the event of a large capacity grounding short circuit fault, the short-circuit current can be effectively transmitted through the large section aluminum metal shell, protecting the safe operation of the entire busbar trunking system and the safety of operators.
PEThe grounding conductor is extremely important for the safety of high current transmission busbar systems. Users can choose an economical shell grounding configuration or a busbar system with a separate PE conductor. All configuration schemes have a PE grounding system cross-section of ≥ 50% of the phase line cross-section.
