The BDK20 Railway Power Connector is a high-capacity 3-phase connector designed for air-conditioned rolling stock. Engineered to transfer 425A at 500V AC, it features spring-loaded floating contact pins and stainless steel mechanisms for vibration-resistant, ultra-low resistance (≤0.0002Ω) connections. Its IP-protected design integrates Φ20 bellows rubber sheaths and disk cladding to shield electrodes from contaminants.
