Product Introduction
Laminated Bus Bar for Telecom
It is also known as a composite busbar or BusBar for Electric Locomotive in the industry, and is a low-inductance and rigid power distribution component that uses multiple layers of flat conductive foils (usually copper or aluminum), sandwiched with thin layers of insulating media, and is laminated and cured by high temperature and high pressure. Different from traditional round cables or soft braided tapes, it is specially designed for high current, limited space, and high-frequency switching environments. In the field of telecommunications, BusBar for Power Electronics is a key physical link connecting rectifier modules, battery packs and UPS inverters. It is designed to eliminate the "last inch" power distribution bottleneck and ensure the ultimate purity and stability of power transmission.
Core Product Features
Ultra-low impedance transmission architecture
Laminated Bus Bar for Mounting Structure of Capacitor Bank uses high-conductivity oxygen-free copper foil (OFHC) as the conductive base material, and eliminates the air gaps between layers through a molecular-level lamination process to achieve optimal management of the skin effect. The multi-layer parallel design reduces the equivalent resistance to 30%-40% of the traditional copper bar solution.
Electromagnetic compatibility optimized design
In response to the dense electromagnetic environment of telecommunications equipment rooms, the internal busbar adopts a staggered and stacked polarity arrangement to form a natural electromagnetic field self-cancellation structure. Bus Bar Solutions for Electrical Power Distribution can meet CISPR 32 Class B radiated emission standards without additional shielding layers.
Modular expansion interface
Standardized through-hole arrays and quick-plug terminal positions are reserved to support smooth upgrades from 100A to 4000A current levels. When the data center expands its power density, there is no need to replace the entire power distribution architecture. It only needs to add parallel modules or adjust the connection topology to achieve long-term value preservation of infrastructure investment.
Material advantages
Not just conductivity, but full life cycle reliability.
The material system we use is based on actual measurements of communication equipment's service conditions for more than 10 years.
conductor material
The main material is high-conductivity oxygen-free copper (C11000 or C10200), with conductivity ≥100% IACS. Current branches, a copper-aluminum composite structure (copper-clad aluminum) can be selected, which is of great significance for high-altitude or wall-mounted communication cabinets for Bus Bar for Power Electronics Bunding Solutions.
insulation material
Standard solution: UL 94 V-0 flame-retardant PET or polyimide film, withstand voltage ≥3kV AC (adjustable according to customer voltage level).
For outdoor base stations or high-humidity scenes, we provide epoxy powder coating (Epoxy Powder Coating), with edge coverage without dead corners, resistance to salt spray, mold resistance, and leakage tracking resistance (CTI ≥ 600V).
Contact interface processing
All terminal contact areas are silver-plated (Ag) or selectively silver-plated, with a thickness of 1.3 to 5 μm, and the contact resistance is stable below 0.1 mΩ.
An optional nickel plating bottom layer + tin plating solution is suitable for aluminum row connection scenarios and effectively inhibits electrochemical corrosion for Bus Bar Solutions for Electrical Power Distribution.
Manufacturing process and technical barriers
Precision stamping and CNC processing
High-speed precision stamping technology is used to ensure that there are no burrs on the edges of the conductor and no stress concentration points. Cooperating with the CNC machining center, the micron-level precision of the installation hole position is achieved to ensure a perfect match with the UPS module without the need for on-site secondary trimming for Laminated Bus Bar for High Current Circuit Board IGBT.
Polymer diffusion welding (Diffusion Bonding)
Different from traditional bolting or soldering, we use mutual diffusion between atoms to form a metallurgical bond under specific conditions. This process eliminates the hot spot effect of contact resistance, making the entire busbar a homogeneous conductor, with a current-carrying capacity far exceeding that of a spliced Bus Bar for Power Electronics Bunding Solutions.
Vacuum lamination technology
Use epoxy resin or polyimide (PI) film as the insulating layer, and perform thermal lamination in a high vacuum environment. This completely eliminates interlayer air bubbles, ensures dielectric strength up to several kV, and has excellent moisture-proof and chemical corrosion resistance.
Application scenarios
