At the beginning of Sep, The Albania customers can’t come to China for mobile substations acceptance test because of COVID-19

The temperature rise of transformer refers to the difference between the temperature of transformer and ambient air temperature.

Recently, there are many rainy days in southern China, especially in coastal areas. Several southern coastal power plants (discharge, photovoltaic, thermal power, etc.)

Moulded case circuit breaker (MCCB) is one of the most common low-voltage electrical components. It can make and break rated current reliably and cut off the current automatically when the current exceeds the trip setting.

The high-voltage load switch is a combined high-voltage apparatus, which is composed of disconnector, fuse, thermal relay, shunt release and arc extinguishing device.

The transformer iron heart magnetic flux is related to the exerted voltage. In the current, the excitation current does not increase as the load increases. Although the load is not saturated, the resistance loss of the coil will increase, exceeding the rated capacity due to the heat generated by the......
