Transformer
A transformer is a static electrical device that uses the principle of electromagnetic induction to convert AC voltage, transmit electrical energy, and distribute power. It is an indispensable foundational component in modern power systems. From power plants to factory floors, and from urban grids to remote construction sites, transformers perform the core tasks of step-up transmission, step-up distribution, and electrical isolation.
Pole-Mounted Circuit Breaker
A pole-mounted circuit breaker is a high-voltage switching device specifically installed on overhead utility poles and plays a vital role in protection and control within modern power distribution networks. As an outdoor high-voltage apparatus, it typically employs vacuum interruption technology, featuring a compact structure, high breaking capacity, long electrical life, and requires little to no maintenance. The core function of a pole-mounted circuit breaker is automatic fault isolation. When a serious fault such as a phase-to-phase short circuit or a single-phase ground fault occurs on the line, the breaker can quickly detect the large fault current and automatically trip within tens of milliseconds, accurately isolating the fault point. This prevents a fault on one line from causing an upstream substation to trip and resulting in a widespread blackout.
High-Voltage Switchgear Series
A transformer is a stationary electrical device that utilizes the principle of electromagnetic induction to facilitate the transformation of AC voltage, as well as the transmission and distribution of electrical energy; it serves as an indispensable fundamental component within modern power systems.
Applications Of Electrical Equipment
Responsible for terminal power distribution of 10kV and below, it steps down medium-voltage power to supply end users including residents, small & micro enterprises and municipal public facilities.
Core voltage conversion hub of high & extra-high voltage power grids (e.g. 220kV, 110kV substations step down voltage to 35kV/10kV in stages), undertaking regional power transfer, voltage regulation and power allocation.
User-specific substations of 35kV and above for factories and industrial parks, designed for heavy load, high power supply reliability and complex industrial power consumption conditions.
Boosting transformation facilities supporting PV, wind power and energy storage stations, which collects clean energy power and steps up voltage for grid connection to the utility grid.
