Three-Phase Cast-Resin Dry-Type Distribution Tran | RFQ Sourcing Details

This three-phase dry-type distribution transformer family is intended for power-frequency electrical distribution. The stated construction uses epoxy-resin casting and an oil-free design.

Available configurations include 6 kV, 10 kV, 11 kV, 20 kV, 22 kV, 33 kV, and 35 kV high-voltage levels, with listed low-voltage options of 0.4 kV, 0.415 kV, 0.433 kV, and 0.48 kV.

The overall stated capacity range is 30–25,000 kVA, although the applicable range depends on the selected voltage class and transformer series. Listed transformer families include SCB10, SCB11, SCB12, and SCZB10 configurations.

The specification data identifies two-winding, core-type designs;50 Hz and 60 Hz options;Class F or H insulation;and off-circuit or on-load voltage regulation options. Listed vector groups vary by configuration and include Yyn0, Dyn11, Yd11, and YNd11.

Copper is identified as the standard winding material, while aluminum is offered as an optional configuration. Protection-level options are stated as IP00, IP20, and IP23. For 10 kV and 6 kV distribution configurations, the stated capacity range is 30–2,500 kVA, with tapping options of +2 × 2.5% and +5%.

For 35 kV and 35/20 kV configurations, the listed capacity range is 800–25,000 kVA. Available customization is stated for voltage, frequency, rated capacity, winding material, loss level, temperature rise, ambient temperature, altitude, and noise requirements.

Sample-based customization, design-based customization, OEM, and ODM services are also listed. The source identifies ISO 9001 and CCC certifications, but buyers should request the exact certificates and confirm that they apply to the proposed model and manufacturing scope.

Claimed loss, noise, partial-discharge, fire-resistance, and efficiency characteristics should likewise be confirmed through model-specific drawings, test reports, and guaranteed technical schedules before purchase.
