Introduction of SG3M Metal Via Connector
The Saichuan SG1M SG2M SG3M metal connector system can achieve 300A at up to 1000V.
With their high mechanical strength ,excellent vibration and shielding, high efficiency when crimping , the SG1M SG2M SG3M connectors are well-suited to typical high volatge EV applications such as the connection between motor, inverter,PDU and battery.
The range includes single-hole, 2-hole and 3-hole connectors, and for maximum flexibility, copper or aluminum cables can be used in seven different cable cross-sections.
