Factory wholesale Heatpipe Heatsink - China High Quality Laminated Bus Bar – D&F Detail:

Laminated bus bar, also called composite bus bar, laminated no-inductance bus bar, low inductance bus bar, electronic bus bar, etc. It is a kind of connecting circuit with multi-layer composite structure. Laminated bus bar is composed of multi-layer conductive material and insulation material.

Laminated bus bar is the highway of electric power distribution systems. Compared with the traditional heavy and messy wiring mode, it has such characteristics as low impedance, anti-interference, good reliability, saving space and quick assembly. It is Widely used in rail transit, wind and solar inverters, industrial inverters, large UPS systems or other components that require electric power distribution.

Our production equipment, please visit our facilities.

The laminated bus bars are customized ones based on users’ drawings and technical requirement. All our engineers in the technical teams have over ten years of experience of developing and producing laminated bus bars, they can help users to optimize the product structure and they are sure to supply a high quality products and satisfactory service to you.

Product Characteristics

1) Low inductance coefficient, compact structure, effectively save the internal installation space, increase the heat dissipation area, and effectively control the temperature rise of the system.

2) The minimum impedance reduces the line loss and greatly improves the high current carrying capacity of the line.

3) It can reduce the damage to components caused by voltage commutation and prolong the service life of electronic components.

4) Reduce system noise and EMI, RF interference.

5) High power modular connection structure components with simple and fast assembly.

Advantages Of Laminated Bus Bar

1)Lower inductance

Laminated bus bars are two or more layers of fabricated copper plates stacked together, the copper plate layers are electrically insulated by insulation materials, and the conductive layers and the insulation layers are laminated into an integral whole through related thermal lamination process.

The connecting wire is made into a flat cross section, which increases the surface area of the conductive layer under the same current cross section, and at the same time, the spacing between the conductive layers is greatly reduced. Due to the proximity effect, the adjacent conductive layers flow opposite currents, and they produce The magnetic fields cancel each other out, so that the distributed inductance in the circuit is greatly reduced. At the same time, due to its flat profile characteristics, the heat dissipation area is greatly increased, which is beneficial to the increase of its current carrying capacity.

1) Structure

Compact structure, efficient use of space and well control system temperature.

Reduce the number of components and increase the reliability of the system.

Easy to install and maintain.

Simple and beautiful.

The influence of DC bus insulation layer is as follows:

The thickness of the insulation is important;The thickness of insulation layer is a function of additional stray inductance;

The thickness of the insulation layer is taken as a function of the partial discharge of the additional high frequency capacitor.

The inductance of the bus is directly proportional to the thickness of the insulation material between the bus bars.
