15kVA Railway Transformer Single Phase
Transformer Isolation for Railway project
Transformer Isolation for Railway project
250kVA Isolation Transformer Medical application and special environment requirements for enclosure Epoxy cast transformer with F1 fire rating ,C1 climate rating and E2 environment rating.
February 2022 kick starts a busy time for Tortech with many transformer products under-way.This transformer was required for a special project for renewable power battery installation.
Toroidal transformers Made in our Sydney factory toroidal transformers made to Australian standards for railway standards.
An Automatic Regulator is designed to correct Power quality problems like brownouts, surge, over-voltage, sags, Imbalance, unbalanced current, line noise etc. in the main power supply. Our voltage regulators features voltage regulation, isolation, Transient surge protection, or any combination of these in a all in one solution.
Another three phase transformer project designed for a special railway application.
This three phase transformer project is designed for a special railway application. Made in a robust Stainless steel 316 material enclosure it is IP 56 rated.
This is a 800kva 3 phase unit recently ordered on Tortech P/L. It is 380v +/-20% input and 380v +/-2% output at 50Hz. It weighs over 1000kg . It has a small computer to control the output. The complete unit is housed in a IP20 enclosure.
A powerful 12 kW single to three phase Rotary converter Motor is external – in this case the motor is larger than standard so is mounted externally on black pallet.
3 Phase Variac and High voltage DC transformer Power supply 1400V DC at 10Amps.
