Revolutionizing Cable Grease Filling with Smart Pressure Control
Cable manufacturing demands precise lubricant filling to ensure smooth signal transmission and long-term durability. Traditional manual adjustments lead to over-greasing, wasted materials, and inconsistent quality. This article explores how electro-pneumatic proportional valves address these challenges by:
Closed-Loop Pressure Control: Maintain ±0.3 bar stability for uniform grease distribution.
One-Touch Preset Switching: Instantly adapt to 50+ cable diameters (1–50mm).
Real-Time Flow Feedback: Auto-correct deviations via 4–20mA/PROFINET signals.
A case study shows a 30% reduction in material waste for high-voltage cable producers.

The Precision Challenge in Cable Grease Filling
Under- or over-filled lubricant in cables causes:
Signal Loss: Air gaps in communication cables.
Friction Damage: Insufficient grease accelerates wire abrasion.
How Electro-Pneumatic Valves Optimize Filling
Micron-Level Pressure Accuracy
0.1–10 bar Control: ±0.3% stability for cables from 1mm² to 240mm².
Viscosity Compensation: Auto-adjust for temperature-driven grease thickness changes.
Anti-Pulsation Design: Eliminate pressure spikes causing uneven coating.
Smart Process Integration
HMI Presets: Store 50+ recipes (e.g., CAT6 vs. HV power cables).
PLC Synchronization: Match pressure to line speed (0.5–5 m/s).
Leak Detection: Alert if flow exceeds tolerance during idle periods.
