Pressure Plate/Bar Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

The pressure plate/bar is a critical component of grounding clamps, designed to apply uniform force to the conductor or ground rod, ensuring low-resistance electrical contact. It is typically made of high-strength materials to withstand mechanical stress and environmental conditions.

Working Principle

The pressure plate/bar uses mechanical leverage or spring tension to press the conductor against the clamp body, creating a stable electrical connection. The force is distributed evenly to minimize contact resistance and prevent loosening due to vibration or thermal expansion.

Materials

High-strength copper alloy (e.g., C11000) or stainless steel (e.g., 304/316) with corrosion-resistant coating.

Technical Parameters

Width 20-50 mm
Length 50-200 mm
Hardness Rockwell B 70-90
Thickness 3-6 mm
Surface Finish Bare or tin-plated

Standards

IEC 61238-1, UL 467, DIN 46228
