DIN 42530 1kV 1250A Transformer Bushing
Low Voltage Transformer Bushings
Product Overview
A DIN 42530 low voltage transformer bushing for power transformers, rated 1 to 3 kV at 1250 A. The shell is porcelain with copper fittings. Within the related DIN 42536 family the creepage steps from 50 mm at 250 A to 75 mm from 630 A upward, with weights rising from 0.26 kg at 250 A to 2.05 kg at 3150 A. Transport is by export carton on a wooden pallet.
- DIN 42530
Key benefits
Why Buyers Choose This Part
- 1250 A rating for the higher-output distribution transformer sizes
- Copper fittings for a low-resistance path at high LV current
- Rated across the 1 to 3 kV band so one part covers both classes
- Export carton and wooden pallet packing as standard
Application scenarios
Where It Is Used
- Low voltage side of power and distribution transformers at 1250 A
- Transformer assembly lines running DIN LV terminal patterns
- Replacement on larger distribution units during overhaul
- Export orders shipped on pallets to a transformer plant
Who it is for
Who It Suits
- Power and distribution transformer manufacturers
- Transformer service workshops handling larger units
- Distributors supplying the DIN LV bushing range
Problems it solves
What Goes Wrong Without The Right Part
- LV terminals that heat because the conductor path is undersized at 1250 A
- Transit damage to small porcelain parts shipped loose
- Two part numbers needed for 1 kV and 3 kV terminal boards
- Creepage selection across a family of current ratings

Comparison
How It Compares
| DIN 42530 1NF250A | The 250 A part has 50 mm creepage and weighs 0.26 kg. The 1250 A version is a substantially larger conductor path for higher LV output. |
|---|---|
| DIN 42539 3 kV series | DIN 42539 is the dedicated 3 kV family with its own creepage table from 120 mm upward. Use it where the drawing specifies 42539. |
Use guide
Before You Order And After It Arrives
- Check the LV terminal board takes the DIN 42530 pattern
- Size the connection hardware for the full 1250 A rating
- Keep the pallet packing intact until installation
- Match the fitting metal to your LV busbar
