Every NAHU product is made in our own ISO 9001 certified factory in Wenzhou — and we run the same metering equipment on our own production lines. What we sell, we use.
NAHU supplies the full factory metering kit — indoor CTs, metering boxes, and load break switches — and proves it daily at our own plant: No. 2188 Zhongxin Avenue, Liushi Town, Yueqing City, Wenzhou, where ISO 9001 quality control sits next to the switchgear we build.
Indoor CTs on every feeder and switchboard panel feed live consumption data, exposing waste and supporting energy-saving programmes. NAHU metering boxes tie each line's CT/VT signals together cleanly.
Compact metering boxes and instrument transformers mount cleanly in LV and MV switchgear, keeping panels tidy and accurate. NAHU indoor CTs are available in the bar, wound, and split-core styles panel builders expect.
Load break switches and protection CTs isolate production lines safely for maintenance and protect motors and drives from faults. NAHU switchgear accessories complete the distribution chain end to end.
NAHU's Wenzhou factory — No. 2188 Zhongxin Avenue, Liushi Town — is ISO 9001 certified and manufactures every transformer we ship. The metering we sell to factories is the same equipment monitoring our own production and test lines, which is exactly why we stand behind it for yours.
From the incoming panel to the last production feeder, these three product families cover factory-wide metering and switching.
Indoor CTs in bar, wound, and split-core styles for panels, feeders, and retrofits across the plant.
Indoor VTs for MV panel metering and protection, sized to standard factory switchboard envelopes.
Combined CT/VT metering boxes that consolidate measurement for clean, auditable factory metering points.
