CAREPOLE was developed by Siemens Energy for your overhead distribution line networks. CAREPOLE answers the challenges which transformers can possibly meet. Its windings are sealed with cast resin under vacuum, separated from the core, and the insulation is solid and resist the dielectric loads in the distribution network. The cast resin also protects your unit against severe weather conditions. High- and low-voltage bushings are cast in one piece with the windings. This technical design makes CAREPOLE especially reliable and unsusceptible to failures. Do you need an off-load tap changer? We can provide one near one of the top high-voltage bushings. It is set via a patented tap panel when the transformer is de-energized.
Weatherproof design
Your CAREPOLE withstands any weather conditions and ensures a reliable operation. The winding surfaces and core are in direct contact with the ambient air, resulting in efficient natural heat exchange. The frame surrounding the core creates a solid mechanical structure that protects the unit against corrosion and direct sunlight. The frame also serves as a lifting and fastening mechanism for the transformer. A special manufacturing process and advanced sealing compound ensure lownoise operation and perfect contact between frame and core. The core is wound from highquality electrical steel. The solid insulation of CAREPOLE is stable under all weather conditions and prevents moisture from penetrating the windings and core.
Overload and short circuit capability
CAREPOLE can withstand higher temperatures than liquid-filled transformers, due to the solid insulation. Accordingly, CAREPOLE units can be overloaded for longer periods of peak demand and can better withstand short-circuit effects.
