DIN 3KV6500 Transformer Bushing Insulators
product description
DIN 3KV6500 Transformer Bushing Insulator is an electrical component that meets DIN Standard
Rated Voltage: 3KV
Rated Current: 6500A
Creepage Distance:Min130mm
Transformer bushings like the DIN 3KV6500 are used to:
1.Provide electrical insulation between high-voltage transformer terminals and the grounded tank.
2.Facilitate conductor connection (cable or overhead line) to the transformer.
3.Prevent flashovers/leakage currents in harsh environments (humidity, pollution, UV exposure).
4.Support mechanical loads from connected cables/busbars.
features

Industrial power systems where DIN standards are followed.
Renewable energy systems (wind/solar substations).
Compliance & Testing:
DIN standards ensure compatibility with European electrical grids.
Tests include:
Power frequency & lightning impulse withstand.
Partial discharge tests.
Mechanical load tests
Advantages of DIN 3KV6500 Transformer Bushing Insulator
The DIN 3KV6500 bushing insulator offers several key advantages, making it a reliable choice for medium-voltage transformer applications. Here’s why it stands out:
1. High Electrical Insulation Performance
Optimized for 3 kV systems (or higher, depending on exact specs) with excellent dielectric strength.
Low partial discharge levels, ensuring long-term reliability.
Effective creepage distance design to prevent tracking and flashovers, even in polluted or humid environments.
2. Robust Mechanical Strength
Withstands high mechanical loads (e.g., wind, ice, and conductor tension).
Durable construction (porcelain or composite polymer) resistant to cracking and deformation.
Vibration-resistant, ideal for transformers in industrial or high-load environments.
3. Weather and Environmental Resistance
UV-resistant (if polymer-based) or highly glazed (if porcelain) to prevent degradation.
Hydrophobic properties (in silicone rubber composite types) reduce moisture absorption.
Corrosion-resistant metal parts (e.g., aluminum or stainless steel flanges).
4. Compliance with DIN Standards (German Engineering Quality)
Guaranteed compatibility with European power systems.
Rigorously tested for electrical, thermal, and mechanical performance.
Interchangeable with other DIN-standard bushings, simplifying replacements.
5. Long Service Life & Low Maintenance
Stable performance over decades with minimal aging.
No regular cleaning needed (if using composite insulators with self-cleaning properties).
Resistant to thermal cycling, preventing cracks due to temperature fluctuations.
6. Versatile Applications
Suitable for oil-filled or dry-type transformers.
Used in indoor/outdoor installations (depending on material).
Compatible with renewable energy systems (wind farms, solar substations).
