FAQ
11kV OLTC Oil-Immersed Transformers — Common Questions
To prepare an accurate quotation for 11kv oltc oil-immersed transformers, please confirm: capacity, high voltage, low voltage, frequency, phase, application, installation environment, standard/reference requirement. Sharing a single-line diagram or specification sheet speeds up the response.
Send your project specification (capacity, voltages, frequency, installation conditions) and our engineering team will confirm the configuration and a quotation.
Confirm the high-voltage and low-voltage ratings, the system frequency (50 Hz or 60 Hz), and the installation environment (indoor/outdoor, altitude, ambient temperature, corrosion). Typical range for this page — High voltage: 11kV; Frequency: 50 Hz / 60 Hz.
Cooling method, vector group, tap-changer type, winding material (copper/aluminium), and accessories/monitoring all affect design, price, and lead time. Configurable here — Cooling: ONAN / ONAF optional.
Yes — 11kv oltc oil-immersed transformers can be configured to project requirements (voltage ratio, cooling, vector group, tap range, accessories). Share your specification and we will confirm the design.
