Low-Loss Transformers

Product Overview

The low-loss line covers the three series most used in export markets: the S11-M fully sealed oil-immersed distribution transformer, the S13 oil-immersed series, and the SC(B)13 epoxy-resin cast dry-type series. Against previous generations, all three cut no-load loss substantially — the core metric for long-term investments evaluated on energy cost.

Key Features

• S11-M: fully sealed corrugated tank, maintenance-free, no core lifting; highly adaptable to overseas site conditions;
• S13: further reduced no-load loss versus S11 — the value choice for new distribution and campus main transformers;
• SC(B)13: the mainstream cast-resin series — flame-retardant, moisture-proof, low noise, installable at the load center;
• All built to GB 1094.1 / GB/T 6451 / GB/T 10228 / IEC 60076 with CE and ISO documentation.

Selection Guide

Convert annual loss energy into local tariffs and compare on TCO: prioritize no-load loss where duty is long and load factor low (S13/SC(B)13); prioritize load loss where load factor is high (S22/SC(B)18). Loss comparison tables and payback estimates: sales@fgtransformer.com.
