The three main types of circuit breakers are: Thermal Circuit Breakers: These breakers operate based on the principle of thermal expansion. When an overcurrent flows through the circuit, the heating effect causes a bimetallic strip within the breaker to bend and trip the mechanism, opening the circuit. Thermal circuit breakers are commonly used in low-voltage applications and are relatively simple in design.

The 10kV ring main unit is a crucial equipment in the power distribution system. It is mainly responsible for steadily delivering high voltage electricity of 10 kV or 35 kV to users, so that everyone can have access to electricity. Not only that, it can also constantly monitor the transformers in the power system and control them to ensure their normal operation. Because it undertakes these important tasks, the 10kV ring main unit has the characteristics of high voltage level and large capacity. However, its size and weight are not large, making it very convenient to use. Next, let's take everyone to get to know the 10kV distribution ring main unit and understand its various aspects.

Socket Box is a power distribution device designed for industrial environments. Socket box is often used in industrial plants, outdoor construction sites, commercial places and other scenes that require multiple high-power power sockets, which can provide a stable and safe power interface to meet the power needs of various types of equipment.

Electrical Insulator is a non-conductive material used to prevent electric current from flowing through it. A good electrical insulator has a high resistance to electrical current. Some commonly used materials that are effective electrical insulators include:

​In modern power systems, the construction and maintenance of distribution stations are crucial. As an emerging power infrastructure, prefabricated distribution stations have gradually attracted widespread attention due to their high efficiency, flexibility and economy.

High voltage switchgear refers to electrical products used for power generation, transmission, distribution, energy conversion, and consumption in the power system. The voltage level is between 3.6kV and 550kV, including high-voltage isolation switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizing devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear.
