Built-in current transformers for outdoor installation
The ZTM Ltd. has mastered the production of built-in current transformers for outdoor installation with cast polyurethane insulation type TV-TM-35-L. These products have the following advantages over the transformers installed inside the tank circuit breakers and power transformers:
1. Ease of installation and maintenance.
2. Ease of switching taps.
3. Saves space in the tank.
Currently, the company is producing current transformers TV-TM-35-A at voltages of 35, 110 and 220 kV. One case can be fitted with several secondary windings. The transformers for electricity metering (accuracy class 0,2S; 0,5S) have the possibility of sealing cap contacts.
Our company has its own constructor department that allows the company to carry out a full cycle of transformers testing.
Calculation of the costs for transformers is done in a short time according to the customer requirements. The company manufactures some type of products on a regular basis.
