Technical Overview

11kV — The Global Distribution Standard

11 kV (also written 11kV or 11,000 V) is the most widely deployed medium-voltage distribution class outside the Americas. It is standard in Sub-Saharan Africa, the UK, India, Pakistan, Bangladesh, Southeast Asia, and GCC countries. Distribution transformers at this voltage class step down to 0.4 kV (400 V / 230 V) for end-user supply.

XinHuan's 11 kV transformer range is manufactured to IEC 60076 as the primary standard, with GB/T 1094 cross-reference available. The S13 and S22 series oil-immersed designs feature amorphous or grain-oriented silicon steel cores for low no-load losses, hermetically sealed or conservator tank options, and ONAN standard cooling with ONAF upgrade available for high ambient temperature sites.

Standard accessories include: off-circuit tap changer (±2 × 2.5%), oil level gauge, thermometer, pressure relief valve, earthing terminal, and cable boxes. Buchholz relay, winding temperature relay, and on-load tap changer (OLTC) available on request.
