CB250 Outdoor Transformer Porcelain Bushing
Low Voltage Transformer Bushings
Product Overview
An outdoor low voltage transformer porcelain bushing supplied under the CB250 reference. It carries the transformer winding lead through the tank into open air, insulating it from the tank and holding it in position. Detailed dimensions for the CB250 are confirmed against the drawing before an order is placed, and the bushing can be produced to a customer specification.

Comparison
How It Compares
| DIN 42530 low voltage bushings | The DIN series publishes fixed creepage and weight figures per current rating. The CB250 is ordered against its own reference, so we confirm the drawing with you first. |
|---|---|
| Indoor LV bushings | This part is specified for outdoor service. Do not substitute an indoor bushing onto an outdoor tank. |
