Electrical transformers have undergone tremendous changes

These superconductors will be compatible with other electrical devices such transformers, transmission cables and power limiters. For example; a current limiter with a capacity of 10.5 kilovolts and 200 amperes are being tested in some of the power research centres. The need for high-temperature superconductors has been created by the ever increasing number of power consumers. Such innovated superconductors will have the capacity to withstand high-voltage from power generators. Through this, China will have the capacity to supply electricity to major factories and to domestic consumers (Andersen, 2001).

Electrical transformers have undergone tremendous changes through innovation in electric related matters. For instance, a high-voltage power holding 3-phase transformer which can withstand a capacity of 630 kV/10.5 kV for high use have been developed in Japan. Such transformers contain iron core solenoid and other high-voltage resistant materials such as stainless steel. These stainless steel materials get enforced by silver materials coated by polyamide films. This combination has allowed generation of modern electrical transformers which can withstand high electric voltage as well resistance to high temperatures.

In China, modern electric transformers which have an automatic and modern cooling system have been developed. These transformers have replaced the old antiquated transformer which used circulating cooling oil in small metallic pipes. Through this, the conduction of electricity has been necessitated as a high level of degree Celsius can be lowered within a very short time. The inductor that is used is shown below
