1.Why ENC GROUP LTD?
More than 10 years of experience in electrical insulation
Cover the whole category of electrical insulation products
Goods with excellent quality
2.What are insulation materials?
Those materials used to electrically insulate the transformer’s windings, turn-to-turn or layer-to-layer, and other assemblies in the transformer such as the core and busswork. Nomex, polyester, epoxy, rubber, Glastic and plastic are commonly used as insulating materials in the electrical industry.
3.What is a transformer and how do it work?
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static solid state device, which insures under normal conditions, a long and trouble-free life. It consists, in it’s simplest form, of two or more coils of insulated wire wound on a laminated steel core.
When voltage is introduced to one coil, called the primary, it magnetizes the iron core. A voltage is then induced in the other coil, called the secondary or output coil. The change of voltage (or voltage ratio) between the primary and secondary depends on the turns ratio of the two coils.
4.What is “CLASS” in insulation?
Insulation class was the original method used to distinguish insulating materials operating at different temperature levels. Letters were used for different designations. Letter classifications have been replaced by insulation system temperatures in degrees celsius. The system temperature is the maximum temperature at the hottest spot in the winding.
5.Are you a factory or trading company?
We are a factory, we can guarantee our price is competitive and we will ship goods very fast.
6.What's your main products?
