Local Market Notes

What Vietnam Buyers Usually Care About

22kV is the standard medium-voltage distribution level across industrial parks and EVN power networks in Vietnam.

Manufacturing plants and electronics factories require strict voltage stability, low temperature rise, and low-loss transformer operation.

Complete export documentation provided for seamless customs clearance at Haiphong, Cat Lai, or Da Nang ports.

Procurement Notes

Information That Speeds Up Approval

Specify whether 22kV or 35kV primary voltage rating is required, and whether amorphous alloy core or silicon steel core is preferred.
