CuZn10 Brass Die Casting Solution for High-Voltage Line Clamp Manufacturing
Project Overview – Demands on Line Clamps in High-Voltage Electrical Systems
High-voltage line clamps are critical components in power transmission systems. They require exceptional conductivity, mechanical strength, and resistance to environmental corrosion. These clamps must maintain secure, low-resistance electrical contact while withstanding mechanical vibration and thermal cycling. CuZn10 brass die casting enables mass production of durable, conductive, and corrosion-resistant clamp bodies, providing a cost-effective solution for electrical grid infrastructure.
Material Selection – Why CuZn10 Brass is Ideal for High-Voltage Line Clamps
CuZn10 is a low-zinc, high-copper brass alloy with excellent electrical conductivity, good mechanical strength, and superior resistance to stress corrosion cracking. The alloy’s ductility and castability make it well-suited for precision components that require subsequent post-machining and high surface integrity. CuZn10’s minimal electrical resistivity makes it ideal for current-carrying components such as clamps, connectors, and terminals.
Manufacturing Process Breakdown
Copper Alloy Die Casting with CuZn10
Using copper die casting, we form line clamp bodies with complex geometries including cable seats, bolt channels, and contact pads in a single cycle. Mold design is optimized to ensure complete fill, uniform cooling, and minimal porosity. Wall thickness is controlled within ±0.1 mm for dimensional stability and electrical consistency.
Precision Post Machining for Interface Accuracy
Post machining ensures precise alignment of screw threads, clamping faces, and conductor interfaces. Machined surfaces are held to ±0.05 mm tolerance to guarantee uniform contact pressure, proper fitment with fastening hardware, and minimal contact resistance under electrical load.
Surface Treatment – Shot Blasting for Contact Enhancement
We apply shot blasting to improve surface uniformity and remove oxides. This process not only enhances the mechanical bond for coatings or platings (if applied later) but also creates a matte finish that increases surface area slightly, supporting stable long-term contact performance under high current conditions.
