General information:

    • The CTx-1CxOx current transformer is molded with Huntsman’s Araldite resin system for outdoor application with vacuum casting technology, has very good mechanical and electrical properties, withstands sudden temperature changes, and is resistant to shocks. Being affected by ultraviolet rays, the product is designed to suit tropical weather conditions and heavily polluted environments.
    • The CTx-1CxOx current transformers are of single- or multi-ratio design, which can be changed by connecting the secondary side.
    • There is 1 secondary coil. The secondary winding is used for measurement purposes only. To prevent danger, the secondary circuit of the Current Transformer must always be connected to the load or short circuit. One terminal of the secondary winding shall be grounded during operation.
    • The current transformer can be installed in any position by the four bolts that go into the four holes on the base. The base is made of steel, solid structure and hot-dip galvanized, resistant to wet environments…
    • The outputs of the current transformers are molded to the body, the terminal cover has a cover and the sealing position.


    • Voltage levels… 35kV.
    • Rated primary current…5; ten; 15; 20; 25; 30; 40; 50; 60; 75; 100; 150; 200; 250; 300; 400; 500; 600; 750; 800; 1000; 1200A…
    • Rated secondary current…5A; 1A.
    • Rated frequency…50Hz.
    • Current transformers are designed and manufactured according to IEC 60044-1; IEC 61869-2; TCVN 7697-1.
