Company introduction
1.certification
We have passed ISO9001:2015,CE,SGS approval and IEC report
2.Company profile
Tianjin Grewin is concentrating on transformers for 20 Years and complianted by ISO9001:2015,CB,IEC CB,CE etc.We're always pay great attention to its business philosophy "Quality and Honesty First".GWSCTC660A series retro-fit (split-core) current transformer has been specially designed to facilitate their installation in new or already existing net works. They may be installed without opening any cable or bus-bar circuit. An internal precision resistor across the secondary winding of the CT provides a low safe voltage output. It can save time and the installation costs.windely used in communications,electronics,meters,industrial control,medical equipments and other fields.We are also a provider of power meters and instruments locators. 85% of its products exported to America, Europe, and Asia etc.We sincerely invite you to join us to create a bright future.
