Product Description
The CBRG series dry-type capacitive transformer porcelain bushing (cable-through type) is a high-voltage terminal component specifically designed for epoxy resin cast dry-type transformers. It incorporates a capacitive grading structure and uses high-quality electrical porcelain as external insulation, with an internal cable-through connection design. Suitable for distribution systems with voltage ratings of 24kV and below, this product features excellent electrical insulation performance, mechanical strength, and resistance to environmental aging. It is easy to install and maintain, making it widely applicable in indoor distribution installations with high requirements for fire safety and reliability, such as data centers, commercial buildings, industrial plants, and new energy power stations.
