10 kV Oil-Immersed Distribution Transformer

Overview: A 10 kV oil-immersed distribution transformer is a common starting point for medium-voltage distribution systems. The insulating liquid supports electrical insulation and heat transfer. The proposed unit should be defined by the network, load profile and site conditions rather than by a model code alone.

Where this configuration is considered

Consider this configuration for utility feeders, industrial facilities and commercial distribution where a 10 kV class primary supply is specified. Confirm the exact primary and secondary voltages with the project single-line diagram.

Information to define before quotation

Provide rated kVA, voltage ratio, frequency, tap requirements, vector group, impedance, cooling arrangement, site temperature and installation method. Ask for guaranteed no-load and load losses, dimensions, accessories and the required test schedule.

International standards to review

Reference standards may include IEC 60076-1:2011. The applicable editions, clauses, conformity evidence and test scope must be agreed for the final design and destination market. This page does not claim certification or guaranteed compliance for an unspecified product.

A useful question for the technical brief

Is 10 kV the incoming nominal system voltage, and what secondary voltage and capacity does the load require?
