We hold a substantial amount of stock of transformers, mini-subs and switch gears with an extensive range of KVA’s and voltages. If we do not have it in our stock we will acquire it or manufacture it for you with very short lead times! We manufacture to specifications and have strict quality controls and our products, being either new or refurbished units, both carry a 12 month warranty and come with test reports. www.tristarelectrical.co.za
