Power current transformer and relay protection 6 (10) kV

Transformers of reference type TOL-12-B1 and TOL-12-B2, manufactured for installation in complete distribution devices and used for signal transmission of measurement information of measuring devices and protection, automation and control devices in alternating current installations for a voltage class of up to 12 kV with a frequency of 50 Hz.

Transformers meet the standards of DSTU EN 61869-1:2017, DSTU EN 61869-2:2017 and during operation are subject to verification with an interverification interval of no more than 4 years, the initial verification is carried out in accordance with DSTU 6097:2009.

The transformers are made for internal installation and correspond to the type of climatic performance U and placement category 2 according to GOST 15150. In accordance with DSTU EN 61869-1:2017, DSTU EN 61869-2:2017, the category of transformers according to the ambient air temperature is "-40/40" .

Distinctive features of TOL-12-B1

Reduced weight and dimensions, compared to similar products of other manufacturers.

The possibility of installing the transformer in any position in space.

Absence of air sinks inside the compound.

The accuracy class of the transformer does not change during the entire 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, makes the transformer completely airtight, also increases the reliability of the product and reduces to a minimum the amount of preventive work during its operation, while reducing the weight and dimensions of the product itself.

The construction with insulation from an epoxy compound ensures high fire and environmental safety.
