Application

To improve the reliabilty, lifetime and electrical safety of the computational and office hardware (computers, printers, copy machines etc.), medical and household equipment, electric hand tools, industrial machinery (lifting magnets, frequency converters, etc.) our company suggests to power them through isolating transformers (RT).

The isolating transformer is a transformer dedicated for a part of a power-supply grid, powering a consuming device en route from the power source or the grounding or null grids. The transformer is an isolating one if neither of its secondary coils is not grounded.

The isolating transformers significantly reduce the risk of electrocuting for personnel, as the transformer's secondary terminals are galvanically isolated from both the power source's grounded neutral and the ground.

If a rupture onto a device's casing occurs, ther is no sparking and the device is still functional. The resulting currents are of no danger to the personnel and can't damage the equipment.

Meeting our customer's wishes we can install additional shields between the primary and secondary coils. The shield's grounding improves the transformer's isolating qualities manifold.

The isolating transformers can be used with the equipment of up to 40 kWt (GOST 30030).

Advantages

• RT prolongs life-time of amy electric equipment;
• RT reduces the short-circuiting amperage;
• RT is an additional protecting device;
• RT improves the quality of the power supplying grid as it filters out high-frequency harmonics.

Technical data

Our company manufactures two types of transformers, depending on application: to use with magnet's control units (connection of coils Z-Y) or to use with other equipment (connection of coils Y-Y).
