Import Current Transformer — Buy in Bulk from Supplier in China

The Current transformer from Dessen Co., Ltd. is a wound-type instrument transformer designed for precision current sensing in AC systems up to 1000V. It supports primary current ratings from 10A to 3000A and secondary outputs of 1A or 5A, with accuracy classes typically rated at 0.5 or 1.0. The core uses cold-rolled grain-oriented silicon steel, and the windings are insulated with polyester film for thermal stability up to 130°C. The unit is intended for panel mounting in distribution boards and switchgear.

Standard construction follows IEC 60044-1, with epoxy resin encapsulation for environmental protection. The transformer is not rated for outdoor use and lacks a specified IP rating. Burden values are not listed, but typical applications use 5VA or 10VA loads. While the listing mentions compliance, it does not specify whether the transformer is designed for metering, protection, or both. The design emphasizes compactness and ease of installation, with bolt-on primary terminals for direct busbar connection.

This transformer is commonly sourced by utility companies, renewable energy installers, and industrial maintenance teams for use in revenue metering, fault detection, and load profiling systems. Packaging is typically 20 units per wooden crate with internal foam inserts. Trade terms are not detailed, but common export practices include FOB Shanghai or CIF destination port. Buyers must verify whether the unit meets the required accuracy class for their application and confirm the burden compatibility with connected instruments.

Dessen Co., Ltd. is a registered enterprise located in Jiangyin City, Jiangsu Province, China, with a documented physical address. The supplier is classified as imported with harbor trust tier status, indicating verified export documentation. The listing provides no details on company founding date, workforce size, production capacity, or past client projects. There is no mention of in-house core manufacturing or winding capabilities.

The supplier's response rate and average response time are not recorded on the platform, suggesting limited buyer engagement. The product description focuses on general technical attributes rather than unique manufacturing processes. The absence of specific certifications or test reports in the listing implies the supplier may source or assemble components rather than produce them end-to-end. No claims are made regarding research, development, or proprietary design.
