Analysis of the reasons for grounding the -48V positive terminal of the communication base station

Nov , 28 2025

1. Prevention of Electrochemical Corrosion (The Most Critical Reason) Physical Principle: In humid environments, metal conductors carrying a positive voltage (positive pole) are more likely to attract negative ions from the air, leading to electrochemical corrosion and causing cables and terminals to gradually rust and break. System Design: If the positive terminal of the power suppl...
