ShanghaiKLD-F Series Air-Type Busbar System

Product Selection

Example: KLD-F-G-T-1000A/4P: Kailangde air-type busbar, with a steel enclosure and copper busbar conductors, rated current of 1000A, and three-phase four-wire system.

Scope of application

The CFW series air-type busbar trunking system is suitable for AC three-phase four-wire and three-phase five-wire systems with frequencies ranging from 50 to 60 Hz, rated voltages up to 660 V, and rated operating currents from 250 to 6300 A. It is designed to perform power distribution tasks, connecting low-voltage switchgear to large- and medium-sized loads. This system is primarily used in modern workshops, factories, and high-rise buildings.

Product Features

1. Air-insulated separation provides excellent insulation performance; its safe clearances and creepage distances between phases significantly exceed standard requirements. It features a compact size, low voltage drop, easy installation, enhanced transmission efficiency, flexible future scalability, and a harmonious aesthetic design.

2. The busbar is made of copper or aluminum conductors with high electrical conductivity. After undergoing surface treatment and other processing steps, it is entirely covered with a PVC heat-shrink sleeve. High-strength epoxy resin insulating blocks are used to separate the phases, providing the busbar with double insulation protection and significantly enhancing its insulation performance. Finally, the busbar is enclosed within a grounded metal enclosure, ensuring exceptional safety and reliability.

3. The busbar enclosure is made from high-quality, high-strength cold-rolled steel or aluminum-magnesium alloy profiles. Not only does this design offer a sleek and elegant appearance, but it also significantly enhances the mechanical strength and dynamic and thermal stability of the busbar trunking system, effectively addressing the challenges associated with large-span installations at construction sites. According to system requirements, plug-in interfaces can be installed at any location along the busbar trunking system, allowing for quick installation, convenient tap-off connections, and safe operation.

4. The plug-in installation method makes busbar trunking systems extremely convenient and flexible during installation, significantly reducing installation time; installation is exceptionally easy.
