DIN 42530 1kV 1250A Transformer Bushing

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

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

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 Suits

Power and distribution transformer manufacturers
Transformer service workshops handling larger units
Distributors supplying the DIN LV bushing range

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

How It Is Built

DIN 42530 low voltage transformer bushing
Rated voltage 1 to 3 kV
Rated current 1250 A
Porcelain insulator with copper fittings
Made in China
Export carton and wooden pallet transport packing

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.
