Current Transformer specialized company
#Sunghan Transtek Company Info
Welcome to our homepage with many thanks!
Our company was established in June.
1991 and have been committed to the distribution and research and development of the processing technology of nickel alloy material for electrical and electro-magnetic applications.
We are manufacturing and distributing worldwide C/T's covering wide range of current, DC immune accuracy current transformers, Zero phase current transformers for earth leakage breaker, Current sensors etc.
Our ZCT's offer superior temperature characteristic and narrow output deviation.
The ZCT's for large current capacity guarantee good unbalance property with high sensitivity.
Our high accuracy DC immune CT's provide solution to the chronic phase angle shift and temperature inaccuracy problems that were frequent with conventional ones.
Our stringent quality control and manufacturing technology enable us to produce not only our own standard products but also customers' own designs with short delivery time by implementing various tools and equipments available.
