Import Current Transformer — Buy in Bulk from Supplier in China

The Current transformer from Tianjin New Ventech Electronic Co., Ltd. is a wound-type instrument transformer designed for accurate current measurement in AC systems up to 1000V. It supports primary current ratings from 5A to 2000A and secondary outputs of 1A or 5A, with a standard accuracy class of 0.5 or 1.0, as commonly required in metering and protection circuits. The core is constructed from high-permeability silicon steel, and the winding uses insulated copper wire with Class B thermal rating for stable performance under continuous load.

Typical insulation materials include epoxy resin encapsulation for moisture resistance and mechanical protection, and the design follows IEC 60044-1 standards for instrument transformers. This model is suited for indoor installation in switchgear panels, with an IP20 enclosure rating. While the listing does not specify bushing type or burden class, standard burden values range from 2.5VA to 10VA depending on connected metering devices. The transformer is non-saturation rated for normal operating conditions but does not claim overcurrent tolerance beyond 20x rated current.

This transformer is commonly purchased by electrical contractors, substation operators, and industrial automation integrators for use in energy metering, relay protection, and load monitoring systems. It is typically shipped in bulk packaging of 10 to 50 units per carton, with foam padding and moisture barrier. Trade terms are not listed, but standard Incoterms for China exports include FOB Tianjin or CIF destination port. Buyers should confirm exact burden, accuracy class, and dimensional tolerances before ordering.
