Standard Transformer Porcelain Bushing

The Standard Transformer Porcelain Bushing combines an electrical-porcelain insulator with metal conductive components for insulated conductor exit and mechanical support on distribution transformers.
Common voltage coverage is 1–35 kV, with application in 50 Hz or 60 Hz power systems according to the required insulation level.
Its general-purpose configuration supports regular transformer production, spare-part planning, and replacement work.

Construction and Installation Options
 

The porcelain body provides external insulation and supports the conductor assembly at the transformer outlet.

Tank-cover, threaded, and flanged mounting structures are available, so the installation form can follow the transformer design rather than a single universal interface.

The material combination and mounting method should be reviewed together when replacing an existing bushing.

Buyers managing repeat production can use the same confirmed dimensions as a purchasing reference for subsequent batches.

Dimension Matching for New or Existing Equipment

 

Overall height, conductor diameter, mounting-hole diameter, terminal form, and shed dimensions can be configured from the transformer drawing.

OEM/ODM work can follow tank-cover, conductor, and terminal drawings, as well as an existing sample or technical prototype.

For old equipment replacement, buyers can reproduce the confirmed interface dimensions instead of changing the surrounding transformer structure.

Production Review Before Packing

 

Manufacturing and inspection cover raw materials, porcelain forming, glazing, firing, and finished-product checking.

The production base has conditions for porcelain electrical-product manufacturing and inspection, with full inspection before packing.

Third-party inspection can be arranged when required by the purchasing project.

Packing Around the Complete Assembly

 

Packaging is selected according to porcelain shape, conductive components, and destination receiving requirements.

Standard specifications generally require 30 days for production, while customized versions generally require 45 days. Production images or video can be supplied during order execution.

When ordering the Standard Transformer Porcelain Bushing, provide the transformer voltage, frequency, mounting method, conductor size, and installation drawing to confirm the configuration before batch production.
