Support for customized designs → Meets project requirements for different current paths, shapes, and terminal arrangements
Key Product Features: Precisely Matches Stringent Industrial Requirements
Integrated Structure
Utilizing a multi-layered composite structure with alternating conductive and insulating layers, multiple conduction paths are integrated into a single component, significantly reducing the cluttered layout of traditional cable connections, minimizing internal space occupancy, and supporting the overall miniaturization of the equipment.
01
Low Conductive Loss
High-purity conductive materials are selected, and conductor cross-section design and current path layout are optimized to reduce resistance loss and skin effect. Power transmission efficiency is improved by 15%-30% compared to traditional cables, effectively reducing equipment operating energy consumption.
02
High Insulation Reliability
The insulation layer uses a special composite material that is high-voltage resistant, temperature resistant, and flame-retardant. After special processing, the insulation strength can reach over 10kV/mm, effectively resisting the erosion of harsh industrial environments such as humidity, dust, and vibration, ensuring safe power transmission.
03
Superior Mechanical Performance
The overall structure is molded, possessing excellent rigidity and deformation resistance, capable of withstanding vibration and impact during equipment operation. It also exhibits excellent thermal stability, maintaining stable performance within a wide temperature range of -40℃ to 150℃.
04
Easy installation
The integrated design reduces the number of bolt fixing points in traditional connections, and with precisely positioned mounting holes, it enables rapid assembly and disassembly, reducing equipment assembly and maintenance costs and improving construction efficiency.
05
Detail Showcase – The Devil Is in the Details, Quality Is Seen in the Millimeters
Edge Treatment
All conductor edges are deburred and rounded to avoid the risk of sharp discharge and prevent scratches to the insulation or personnel during installation.
Interface Precision
The dimensions and positional tolerances of bolt holes and locating pins are strictly controlled to ensure a perfect match with your devices, smooth installation, and even stress distribution.
Insulation Alignment
After lamination, the insulation edges of the inverter busbars are perfectly aligned with the conductor edges, without misalignment or overflow, demonstrating superior process control.
