• DIN 42530 1NF250A Low Voltage Transformer Bushing

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

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

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 Suits

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

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

How It Is Built

• Manufactured to DIN 42530
• 1 kV class at 250 A
• 50 mm creepage distance
• 0.26 kg net weight
• Supports and fixes the transformer winding lead
• Moisture-proof and anti-fouling surface

Published Figures For This Product

Every value below comes from the manufacturer data for this item. Figures not listed are confirmed against the drawing before an order is placed.

Creepage Distance	50 mm
Net Weight	0.26 kg

Materials

• Electrical porcelain body
• Copper or aluminium alloy conductor

Process

• Forming
• Glazing
• Firing
• Conductor assembly
• Routine electrical test

Testing

• Creepage checked against the 50 mm figure
• Insulation test between conductor and mounting
• Weight and dimension verification

Certification

• Manufactured to DIN 42530
• ISO 9001 quality management system

Customisation Options

• Other current ratings within the DIN 42530 family
• Conductor metal matched to your LV busbar
• OEM and ODM marking

How It Compares

DIN 42530 1KV630A	Same 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 series	This 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
