Quality Instrument Transformers
SADTEM is a private company, specializing in the manufacture of electrical transformers for Medium Voltage Measurement and Protection both for indoor and outdoor use.
Rexel Utility has integrated the best in quality instrument transformers from SADTEM providing many advantages such as :
- Casting process and resin allows for reduced sizes, reduced weights and optimum dielectric strengths
- Pioneers in the use of cycloaliphatic resin insulators providing excellent creepage distances and resistance to surface tracking and flashover
- Easy to mount in any position either on their own or in clusters on pole mounted bracket assemblies or in padmount enclosures
- Dry type design – compact, rugged and require no maintenance
- Built to CSA/IEEE standards and are Measurement Canada approved
