It incorporates a full metallic shielding (copper /aluminum) between primary & secondary winding
Isolation transformers are being used to protect electronic & sensitive creative equipment such computer & peripherals medical instruments, digital machines & cnc m/c from the excessive line voltage transient, spikes/surges which produced in the system. Apart from this, isolation transformer also obstructs those disturbances that are generated by the noisy equipment from being injected into the power line i.E. It filters common mode noise usually an attenuation of approx. 30 db.
In shielded transformer, 4 low impedance path exist for noises to pass to secondary & vice versa. These paths are:
- high value of coupling capacitance.
- maximum leakage of magnetic field.
- leakage current
- static transformers of electric noise.
The multiple shielding techniques employed in isolation transformers reduce the inter winding capacitance below to 0.005 pico farad & increase d.C isolation to over 1000 m ohms.
Application of isolation transformer
ò protection of microprocessor based machines from damage & data loss
ò where ground of equipment cannot be earthen
ò when no current leakage is permitted in equipment
ò when protection is needed against high frequency line losses & strong surges.
Introduction:
Our transformers had exported to more than 50 countries in the world up to 200mva 230kv, we offers a complete range of power and distribution transformers designed to grant the reliability, durability, and efficiency required in utility, industrial, and commercial applications. QingZhong is a major transformer manufacturer throughout China offers both liquid-filled and dry-type transformers as well as services for complete life-cycle support, including replacement parts and components.
We are engaged in supply of a wide range of Power & Distribution Transformers from 160kVA to 415MVA, 500kV Class to fulfill the specific demands of the Power & Industrial sectors and the Railways.
These Transformers find use in industries such as Power Utilities, Process Industries, Railways, Mines, Electricity Boards, Industrial users etc in both the Domestic as well as Global markets
We also offer Switchgear products ranging from 3.3kV to 420 kV, to meet the requirements of electrical sub-stations and installations.
Transformer Types
Distribution (160kva & Above)
Power
Dry Type/Oil filled/Cast Resin
1. The low-voltage winding is of cylindrical or spiral structure, with high mechanical strength and good short-circuit resistance.
2. The corrugated oil tank is adopted to replace� the oil conservator. The oil tank cover and the oil tank are all-welded along the edge or fastened with bolts, thus prolonging the service life of the transformer oil.
3. After oil removal, embroidery removal, and phosphating treatment, the product is sprayed with three times of primer and one time of finish paint inside and outside. The product is salt fog proof, damp heatproof, and fungus� proof, which can meet the special requirements of metallurgy, petrochemical system, and wet and polluted areas. It is beautiful� and reliable.
4. The transformer oil tank is� fully sealed, and� equipped with� pressure reducing valve, signal thermometer, gas relay, etc according to the standard requirements to ensure the safe operation of the transformer.
5. This series of products are beautiful in appearance, small in size, and can reduce the installation area. It is an ideal maintenance-free distribution product.
