Oil immersed transformers utilize liquid insulation and cooling to deliver high efficiency, excellent thermal performance, and long service life. They are widely applied in medium-voltage distribution networks where robust load capacity and outdoor reliability are required.
Dry type transformers are designed with solid insulation systems and air cooling, offering enhanced fire safety, low maintenance, and suitability for indoor or safety-sensitive environments. They are ideal for modern urban and commercial installations.
Built on ANSI/IEEE/CSA frameworks with switchable loop/radial feed options, HIITIO’s three-phase pad-mounted distribution transformers are widely used in commercial parks, residential zones, and renewable energy interconnection points.
Optimized for residential neighborhoods and light commercial loads, single-phase pad-mounted transformers provide compact, safe, front-access cabinet designs for underground distribution systems. Common in suburban distribution networks, new community developments, and distributed renewable systems.
Pole-mounted transformers are widely deployed in overhead rural and suburban distribution networks due to their reliability, ease of installation, and low infrastructure cost. They can be used for single-phase or split-phase distribution in overhead lines.
