Insulation & Shielding
Insulation Systems
POWERTRONIX toroidal transformers are constructed with reinforced insulation and withstand 4,000 V RMS for 1 minute. Minimum creepage distance is 8 mm.
Static Shielding
In an extremely noisy environment, a static shield may be needed to reduce the capacitive coupling between the primary and secondary. Noise suppression [needs decrease?] decrease with larger core sizes.
The static shield consists of copper foil laminated between polyester tape. A larger core size may be required because the shield adds layers to the transformer’s winding window.
Low Magnetic Stray Field
With the primary and secondary windings uniformly wound around the entire core, POWERTRONIX toroidals have a very low magnetic stray field. For extremely sensitive applications, the radiated field can be reduced further by winding a magnetic shield around the transformer’s circumference.
