Current transformers of the TZRL-B type up to 0.72 kV

Current transformers of the TZRL-B type are made for installation in complete distribution devices and are used for signal transmission of measurement information of protection, automation and control devices in alternating current installations for a voltage class of up to 0.72 kV with a frequency of 50 Hz. Transformers can be used together with high-voltage cables or in bus lines (3-110) kV, provided that the main insulation between the current-conducting cores of the cable (bus) and the secondary winding of the transformers is provided by the insulation of the cable (bus). The transformers meet the standards of DSTU IEC 60044-1: 2008, the initial inspection is carried out in accordance with DSTU 6097:2009.
They are made for indoor installation and correspond to the type of climatic performance U and placement category 2 according to GOST 15150. According to DSTU IEC 60044-1, the category of transformers according to the temperature of the atmospheric air is "-40/40".

Distinctive features of TZRL-B:
Correspondence of overall and connecting dimensions with the dimensions of similar transformers of other manufacturers.
The possibility of installing a transformer without cutting the cable.
The accuracy class of the transformer does not change during the service life.
Convenience and ease of installation of the transformer.
The possibility of sealing the secondary terminals of the transformer.
Insulation based on an epoxy compound provides high electrical strength, insulating and physical-mechanical properties of the product, being at the same time its supporting structure, completely seals the transformer, also increases the reliability of the product and reduces to a minimum the amount of preventive work during its operation, while reducing weight and dimensions . the product itself. The construction with insulation from an epoxy compound ensures high fire and environmental safety.
