Varieties of SolaHD general purpose distribution transformers include open coil and core, enclosed, wound, as well as the non-ventilated model. We have also made available models that are single-phased indoor and outdoor as well as three-phased indoor and outdoor having 15 KVA to a maximum of 500 KVA. Other models such as K-factor transformers and models with low temperature rise are built to endure load currents without having to deal with overheating or instability. Should you require a more complex type of transformer to suit your needs, just contact us and we will build one for you.
