Amorphous Alloy Fully-Insulated Low Temperature-Rise 3D Wound Core Dry-Type Transformer (30~3300kVA · up to 35kV)

Amorphous Alloy Fully-Insulated Low Temperature-Rise 3D Wound Core Dry-Type Transformer

Product Overview
This series features a closed 3D wound-core structure that fully exploits the low-loss characteristics of amorphous alloy while overcoming its processing difficulties (hard, thin, brittle ribbon). Combined with a hybrid insulation system of NOMEX® aramid paper, PIF polyimide film and eco-friendly insulating varnish, the transformer offers low losses, strong short-circuit withstand, low noise, fire and explosion safety, moisture and pollution resistance, strong climate durability, crack resistance and low partial discharge — resolving the noise, stability and short-circuit weaknesses of conventional amorphous transformers, at an internationally leading technical level.

Key Advantages

• High efficiency & energy saving: the significant energy-saving benefit of amorphous material, the most balanced magnetic path of the 3D wound core, and ultra-low no-load loss together deliver outstanding savings — the transformer runs around the clock, so every watt saved on no-load loss cuts the annual power bill;
• Superior performance: symmetrical three-phase magnetic circuit of the 3D wound core noticeably improves short-circuit withstand and further reduces noise — quieter, more reliable operation;
• Safe & reliable: fireproof and explosion-proof, moisture and pollution resistant, strong overload and short-circuit capability, excellent climate durability — suited to humid, salty and dusty environments;
• Green & eco-friendly: low no-load and load losses, low no-load current, low partial discharge, low electromagnetic field around the unit (low radiation), explosion-proof capable, easy maintenance.
