ABB and high-voltage autotransformer offers
The equipment links retain the complete published ratings and stated condition. A reconnectable common winding is not a simultaneous 115 kV and 69 kV load claim, and a tertiary voltage does not establish the main-winding load capacity.
Buying a 230/115 kV or 230/69 kV autotransformer
Send the one-line, required MVA, selected common-winding connection, tertiary duty, grounding, insulation, impedance and its rating basis, tap range, fault requirements and protection scheme. The responsible project engineer reviews the unit-specific nameplate, drawings and tests against the intended operating direction.

Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Does J&J have an ABB autotransformer offer?
The public ABB record describes 230 kV autotransformer equipment with a common winding reconnectable for 69 or 115 kV service and a 13.5 kV tertiary. Use the exact rating and duty in that record; current allocation and delivery require written confirmation.
Is an autotransformer the same as a two-winding step-down transformer?
No. Its winding construction and electrical connection differ. A matching ratio does not establish interchangeability; review grounding, currents, protection, tertiary duty and the project specification.
