Structural Features

• "Sandwich" Design: Adopting a tightly stacked "sandwich" structure between phases, the busbar trunking has a more compact and smaller profile. This design enhances the dynamic and thermal stability of the busbar system, reduces impedance and voltage drop, and eliminates the "chimney effect" of the busbar in case of fire.
• Strong Heat Dissipation: Phases and phase-to-enclosure are closely attached, enabling the system to withstand large electric and thermal stresses. Heat generated by the conductors can be quickly dissipated, ensuring a high current-carrying capacity. Joints are fastened with insulated bolts and connected using double copper bars, increasing contact area and reducing temperature rise at joints.
• Excellent Insulation Performance: Conductors are wrapped with flame-retardant cross-linked polyethylene heat-shrinkable sleeves, providing strong insulation. They emit no toxic gases in case of fire, making them environmentally friendly products.
• Flexible Wiring: Plug-in ports are flexibly and conveniently arranged, allowing a large number of 插口 configurations with high versatility. When adjusting the position of electrical equipment, there is no need to modify the power supply system.

Technical Parameters

• Current Rating: Typically ranges from 40A to 6300A, varying by model. For example, Eaton's XAP-S series intensive busbar trunking has a rated current of 250A-5000A, while ABB's LMAX-E series ranges from 250A to 4000A.
• Voltage Rating: Suitable for systems with a rated voltage below 690V, with a general rated insulation voltage of 1000V.
• Protection Class: Available in various protection levels. For instance, Xiangjiang Cable's NYMX busbar trunking units offer IP65, IP54, IP44, and IP40, while ABB's LMAX-E series can reach up to IP66.

Application Scenarios

• Industrial Sector: Widely used in multi-story standard factories, equipment-intensive workshops, etc. It is suitable for high-current trunk transmission and provides stable power supply for various equipment in workshops.
• Civil Construction Sector: Commonly applied in high-rise civil buildings. For example, diesel generator rooms, refrigeration machine rooms, motor control centers, and floor lighting sockets often use intensive busbar trunking for power distribution.

Advantages

• Easy Installation: Compared with traditional cables, busbar trunking is quicker to install, significantly shortening the construction period.
• Space-Saving: With a compact structure and small size, it saves internal space in buildings, especially suitable for places with limited space.
• Long Service Life: Generally up to 40 years or more, with convenient maintenance, reducing later maintenance costs.
• Environmental Protection and Safety: Made of environmentally friendly materials with excellent insulation performance, it emits no toxic gases. It also has good dynamic and thermal stability and protection performance, effectively ensuring electrical safety.
