SINNHONG Unveils 1000V SiC-Optimized Interconnects to Power the 2026 Megawatt Charging (MCS) Revolution in Global Transit

As the global electric vehicle infrastructure enters the era of Megawatt Charging Systems (MCS), SINNHONG, a premier China & Vietnam Manufacturer, has announced the launch of its next-generation 1000V SiC-Optimized EV Bus High-Voltage Wiring Harnesses.

The MCS Era: From 350kW to 1.6MW+

The industry reached a pivotal milestone this quarter as the first public MCS charging sessions were successfully completed in both North America and Europe, delivering up to 1,500 amps through liquid-cooled cables. To support this massive leap in power density, SINNHONG’s new high-voltage power looms are engineered for 1.2MW+ sustained charging cycles, ensuring that Class 8 trucks and transit buses can recharge from 20% to 80% in under 20 minutes—effectively removing the "down-time" barrier for long-haul logistics.

SiC-Inverter Synergy and Zonal Architecture

With 1200V Silicon Carbide (SiC) modules becoming the mainstream choice for 2026 powertrains, SINNHONG has optimized its internal cabling to mitigate high-frequency switching transients (dV/dt stress). By integrating Zonal Architecture HV backbones, SINNHONG’s solutions reduce cable weight by 35% through the use of micronized additive aluminum conductors, directly addressing the "range anxiety" of fleet operators.

Vietnam Hub: Strategic "Non-China Sourcing" for 2026

As North American OEMs navigate the latest Section 301 tariff investigations concluded in April 2026, SINNHONG’s Vietnam-based production hub provides a mission-critical Duty-Free gateway. "Our Vietnam facility is not just a factory; it’s a resilience strategy," said SINNHONG’s Director of OEM Electronics Manufacturing. "By providing Section 301 Tariff Exempt and IATF 16949:2026 certified assemblies, we enable Tier-1 suppliers to meet strict US origin requirements while accessing elite IPC-A-620 Class 3 quality."

Future-Proofing Sustainable Transit

Committed to ESG-compliant manufacturing, SINNHONG also introduced options for 100% recycled copper conductors and LSZH (Low-Smoke Zero-Halogen) jacketing for underground transit systems. As the "SiC-ification" of the energy grid continues, SINNHONG remains the preferred partner for high-fidelity, landed-cost optimized interconnects that power the world's most advanced AI-managed electric bus fleets.
