Electrical systems are becoming increasingly compact, modular, and performance-driven. To meet these demands, Xinyi offers highly customizable E91E aluminum busbars tailored to exact project specifications, including unique dimensions, edge configurations, and surface tolerances.

Precision Width and Thickness Options

Xinyi supplies E91E busbars in a wide range of dimensions to suit low-, medium-, and high-voltage applications. Standard offerings include:

• Thicknesses: 3 mm to 20 mm
• Widths: 10 mm to 200 mm
• Length: Up to 6 meters (custom cut-to-length available)

Tight tolerances are maintained through CNC finishing and quality control to ensure optimal fit during installation.

Edge Finishing Options

The edges of aluminum busbars play a critical role in both mechanical integrity and safety. Xinyi offers various edge treatments to meet installation and performance requirements:

• Square Cut: Standard edge for general electrical enclosures
• Chamfered: Reduces risk of edge cracks and improves insertion into terminals
• Rounded/Radiused Edges: Used in high-voltage applications to minimize corona discharge and improve dielectric safety
• Deburred Edges: Eliminates sharpness and ensures user safety during handling

Why Edge Quality Matters

Improper or rough edges can lead to insulation damage, arcing, and increased wear on connectors. With Xinyi’s advanced finishing lines, busbars are delivered ready for coating, bending, or direct installation—saving time and improving system integrity.

Hole Punching and Slot Customization

Busbars often require holes, slots, or terminals for bolting and connection. Xinyi provides precision punching services based on customer drawings or standard layouts. This includes:

• Round holes, oval slots, and multi-phase patterns
• Standardized spacing for IEC or UL terminal blocks
• Edge notch or bend support for tight panels

Applications Across Industries

Whether you’re wiring an inverter cabinet, retrofitting a substation, or building a custom UPS system, Xinyi’s flexible sizing options for E91E aluminum busbars ensure optimal electrical flow and mechanical fit.
