Key Features

01

Capacity Selection

SZ11: Capacity, high-voltage and low-voltage combination, tap range, and connection group are confirmed before quotation. This point is especially relevant to on load tap changing transformer.
02

Cooling and Insulation

Oil-immersed, dry-type, amorphous alloy, and H-class requirements are reviewed according to installation conditions. For SZ11, check this together with the selected project scheme.
03

Loss Data Review

No-load loss, load loss, impedance, and efficiency-related data should be matched with the selected capacity. On SZ11, confirm the application duty, site layout, and project standard before selection.
04

Project Installation

Foundation, lifting, terminal position, ventilation, and clearance requirements need confirmation before delivery. Use the SZ11 drawings and rated data to confirm this point before quotation.
05

Application Flexibility

Transformer selection can support utility, industrial, commercial, indoor, outdoor, and renewable-energy projects. For SZ11, review this with on load tap changing transformer and the final installation plan.
