Oil Filled Bushing for transformer

 

Name:Oil Filled Bushing for transformer

Type:1kv/250A-4000A+B,10NF250-30NF250

Color: White/Gray

This comprehensive range of transformer porcelain bushings integrates high-voltage (HV) and low-voltage (LV) insulation solutions, engineered specifically for oil-immersed distribution and power transformers. Covering voltage ratings from 1kV up to 35kV and current capacities spanning from standard to heavy-duty levels, this assortment serves as the critical electrical interface between the transformer's internal windings and external power grids.

Applications

-Oil-immersed distribution transformers (10kV/0.4kV, 35kV/10kV)

-Medium-power transformers for industrial plants and substations

-Outdoor power distribution equipment requiring high insulation reliability

-Custom transformer projects with specialized HV/LV connection needs

 

Product advantages

1. Premium Insulation & Reliability

High-strength brown-glazed porcelain with anti-porosity technology, tested to resist flashover in medium-pollution/coastal environments.

Meets IEC 60137, ANSI C57.5900, and DIN 42530 standards for global compliance.

2. Rugged Mechanical Design

Precision-bonded porcelain-flange structure with 44–160kN load capacity, engineered to withstand extreme wind/ice.

Galvanized steel fittings prevent rust, ensuring 30+ year service life.

3. High-Current LV Performance

99.9% pure copper conductors with low resistance design eliminate overheating at 2000A and ensure efficient heat dissipation.

Precision-machined flanges + multi-layer gaskets provide 100% oil/air tightness, stopping leakage at source.

 

 

Oil Filled Bushing for transformer mainly used in transformers and high-voltage overhead power lines to insulate and support wires.

 

Note: The process shown is the production process for this type of porcelain insulator; the appearance is manufactured according to the drawings provided by the customer.

 

 

Oil Filled Bushing packaged in wooden crates, wooden framed cases or other strong enough materials covered with moisture-proof materialoutside.Gross weight of each package not exceeds 3000kgs.

 

 

 

 

Question: What are the common specifications of porcelain insulators?
Answer: 1KV/250A, 1KV/630A, 1KV/1000A, 1KV/2000A, XP70, 10NF250, 20NF/350, etc. Customization based on drawings is also supported.

 

Question: How to ensure that the quality meets the standards?
Answer: We provide production standards. We adhere to strict selection of raw materials and have strict control over each process (molding, sintering, cementing).

Before leaving the factory, the electrical (insulation resistance, flashover voltage) and mechanical (tensile, bending) performance tests will be carried out and corresponding reports will be provided.

 

Question: Do you provide customization services?
Answer: Yes. Special requirements for size, shape and performance can all be customized according to technical parameters and drawings. Our professional team will collaborate to meet customers' needs from design to mass production.

 

Question: What's the delivery cycle for customized products?
Answer: For simple customization, it usually takes 2 - 4 weeks. If it involves adjustments for special performance, it will take 4 - 6 weeks. After receiving the order, we will provide an accurate schedule and communicate the progress in a timely manner.
