Product Details

Industrial Electrical Low Tention Arc Resistant 33KV Compact Substation


Product Description


A substation is an electrical facility used to transform voltage from high to low, or the reverse, along with circuit breaking and switching functions.

• Substations consist of transformers that decrease the voltage of high voltage transmission lines to a level that is usable for distribution lines and consumers.

• Equipment at substations include transformers, disconnect switches, circuit breakers, surge arresters, instrument transformers and control systems.

• Substations receive electrical power from transmission lines and redistribute it on distribution lines that feed industrial and residential users.

• They are also used to transmit power from one transmission line to another when electrical networks are interconnected.

• Substations require substantial space, security precautions and maintenance due to the high voltages involved. Hence they are typically located away from heavily populated areas.

• Main functions of substations are voltage transformation through transformers, circuit interruption through circuit breakers, and transmission line switching through disconnect switches.

• Substations have high and low voltage sections separated by locked metal fences for safety.
