DIN 42530 1NF250A Low Voltage Transformer Bushing

Low Voltage Transformer Bushings

Product Overview

A DIN 42530 low voltage bushing for the 1 kV winding side of a distribution transformer, rated 250 A. It supports and fixes the winding lead so the winding stays in position inside the tank, isolates it from the tank and other metal parts to stop leakage current, and resists moisture and surface fouling. Creepage is 50 mm and the unit weighs 0.26 kg.

  • DIN 42530
Key benefits

Why Buyers Choose This Part

  • DIN 42530 pattern fits the low voltage terminal boards most transformer drawings use
  • 0.26 kg unit weight keeps the LV terminal board light
  • Moisture and anti-fouling performance on the exposed LV side
  • 250 A rating covers the common distribution transformer LV outputs
Application scenarios

Where It Is Used

  • Low voltage side of oil-immersed distribution transformers
  • Transformer assembly lines running DIN terminal patterns
  • LV bushing replacement during transformer service
  • Pole transformers where the LV terminals sit exposed to weather
Who it is for

Who It Suits

  • Distribution transformer manufacturers
  • Transformer repair and rewinding workshops
  • Distributors stocking DIN LV bushings
Problems it solves

What Goes Wrong Without The Right Part

  • LV windings that shift inside the tank because the lead is not fixed
  • Leakage current between the winding and the tank
  • LV bushings that foul quickly and fail in humid climates
  • Sourcing small LV parts in the same DIN family as the HV bushings

Comparison

How It Compares

DIN 42530 1KV630ASame DIN family and voltage class, a lower current rating. Match the bushing to the transformer LV output current.
High voltage bushings in the DIN 42531 seriesThis is the LV side part. The HV side needs the taller, longer-creepage DIN 42531 bushings on the same transformer.

Before You Order And After It Arrives

  • Check the LV terminal board pattern against DIN 42530 before ordering
  • Match the conductor metal to your LV cable lugs
  • Do not over-torque the small fixing, the porcelain body is light
  • Keep the surface clean on pole-mounted units to preserve the anti-fouling behaviour
Questions

DIN 42530 1NF250A Low Voltage Transformer Bushing Questions

Which standard applies?
DIN 42530, the low voltage transformer bushing series.
What is the current rating?
250 A.
What is the creepage distance?
50 mm.
How much does it weigh?
0.26 kg.
Can you supply matching HV bushings for the same transformer?
Yes. We produce DIN 42531 and EN 50180 high voltage bushings alongside this LV range, so one order can cover both sides.
Do you supply in bulk for a production line?
Yes. Send the annual quantity on WhatsApp and we will quote a schedule.
