Product Description

The dimension of the GREWIN electronic toroidal transformer coil winding machine without toroidal coil noise
The Partial List of GW-B  Series Toroidal Transformers with Cable and Mounting Holes:
 
1. Installation: 
 Horizontal (non-conventional-type base plate), sunk, side type, and bridge. 

2.Application: 
Especially low-hum and low-dispersing construction 
Low-level of induction 
High-grade design casing possible 
Statically shield winding and magnetical shield winding optional .
 Be used widely such as audio equipment,communication,new energy areas,Electrical control,Cable TV network etc.         

3.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 as below: 
. Automatic Winding Machine
. Semi-automatic Winding Machine
. Toroidal Winding Machine
. Insert Lamination Machine
. Wave Soldering Machine
. Plastic Termal Ultraviolet Machine
. Domino Ink Jet Printing Machine
 Transformer Multitester for High & Low Frequency
 Layer Insulation Withstand Voltage Tester
 
4.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'. 

5.Certificate 
The certificate of our transformer has CE CQC RoHs UL 

6.Note 
The above-mentioned toroidal 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. 

7.GREWIN'S Dimension : 
External diameter: 55mm-300mm, height :13mm-130mm, Efficiency: 75-98% 
we can design the appropriate products according to customers' requirments such as installation dimension, input and output voltage,power...etc.)
