Products Information

Single Phase Isolation Transformer
Single Phase Isolation Transformer defined: A transformer which isolates the primary circuit from the secondary circuit. An Isolation/distribution type Transformer should be used on all systems that require grounding of the load.

Single Phase isolation/distribution type transformers are ideal for supplying auxiliary lighting circuits from 600V and lower supplies and electric heating equipment.

Features :
General purpose indoor ventilated steel enclosure suitable for dry locations. After fabrication, the enclosure is finished in ASA61 grey powder paint suitable for most industrial and commercial installations.

Transformers up to 75KVA may be readily hung on H-columns, walls, shelves or floor mounted to suite each typical installation. Most units have lifting lugs, conduit knockouts and removable front and back covers for easy access to terminals.

Transformers larger than 75KVA are suitable for floor or platform mounting only.
Transformer terminations rated below 330A are supplied with suitable hardware and lugs for cable connection. Terminations above 330A are supplied with termination pads.

Comparison on Transformer with Toroidal, EI, R, CD Shape Core
Since 1995, we have been playing a leading role to replace the types of R, CD, EI with toroidal type for our customers from each part of the world.
Core EI, R & CD Toroidal
Dimension Not Adjustable Adjustable
Performance Average Better
Reliability Average Better
Price Expensive 10%-30% Cost Saved

Productivity:
Toroidal/annular/ring transformer 2 million PCS,
EI transformer 3 million PCS annually;
Three Phase Transformer 50000pcs
Others 100000 pcs

Workforce:
About 200 workers, 5 technicians, 2 senior engineers

Equipment:
Over 50 sets toroidal/annular/ ring coil winding machines, 3 EI type transformer lines, 2 sets of vacuum annealing furnaces, A set of nitrogen and hydrogen production equipment.

Warning
Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'.

Label Info:
Certificate Logo, Basic Electronic Data, Manufacture's Information, also can be printed according to customer's Advice.
Bar Code available according to customer's advice.

Certificate
The certificate of our transformer has CE CQC RoHs UL

Note
The above-mentioned single phase Isolation  transformer is frequently-used, we can also manufacture the products by customer design. And the specification is for reference, if has the change further, please take the material object as the standard.
