Long Shed Transformer Bushing

The Long Shed Transformer Bushing is used for transformer conductor outlets where a longer external insulation path is required. Common application voltage is 10–35 kV.
Its extended shed profile is suited to outdoor, high-humidity, salt-mist, and industrial-dust conditions where pollution level affects creepage selection.
Buyers should confirm both system voltage and the real site environment before fixing the shed arrangement.

Long-Shed Geometry and Maintenance

High-strength electrical porcelain forms the insulating body, with a glazed surface that supports routine cleaning and exposure to rain in outdoor service.

The upper and lower shed distribution increases the surface leakage path while keeping overall installation height under project control.

Shed quantity, outside diameter, and creepage distance are not treated as one fixed specification; they are set according to pollution level and technical requirements.

Interface Choices for Equipment Matching

Flanged, threaded, or dedicated mounting-base interfaces are supported according to equipment drawings.

OEM/ODM production can follow a transformer drawing or physical prototype, with interface details, shed dimensions, and external insulation requirements confirmed before production.

A pre-production sample can be arranged for batch-order confirmation when project dimensions need physical verification.

Porcelain Process and Verification

Production covers raw-material treatment, forming, clay preparation, glazing, firing, and subsequent inspection.

Mechanical, electrical, and dimensional inspection equipment is available for production control.

Quality management covers incoming material, manufacturing, and finished-product release. Finished units receive 100% inspection before packing, and third-party inspection is accepted.

Export Order Planning

Export packing can be configured to destination receiving requirements. Standard production is generally 30 days and customized production generally 45 days.

Photo or video progress updates are available during production, and EXW, FOB, and DDP terms are supported.
