What is switchgear?
Electrical switchgear refers to a centralized collection of circuit breakers, fuses and switches (circuit protection devices) that function to protect, control and isolate electrical equipment. The circuit protection devices are mounted in metal structures. A collection of one or more of these structures is called a switchgear line-up or assembly.
Switchgear is commonly found throughout electric utility transmission and distribution systems as well as in medium to large sized commercial or industrial facilities. Standards for electrical switchgear are defined by IEEE in North America and by IEC in Europe and other parts of the world.

How does switchgear work?
Electrical switchgear refers to a collection of circuit protection devices (circuit breakers, fuses or switches) mounted in a common, metal enclosure. The circuit protection devices distribute power to various sections of a facility and the electrical loads within those sections. They also provide protection to individuals and equipment throughout the facility by limiting the current flow through the system to safe levels.
Applications of Switchgear
Some of the application areas of ZTelec Group switchgears are as follows:
Industrial power distribution: Both these devices are used in different plants and factories where special attention needs to be given to surge and overload protection. These switchgears help in a better and organized distribution of power to the machines in an industrial unit.
Solar power generation: These devices also find application in various types of PV installations. As voltage and surge regulation is mandatory in every solar power installation, these switchgears regulate the passage of electric current from the main unit to the subunit.
Residential power distribution: These switchgears are also installed in different residential societies and complexes. Generally, at these places there is a combination of several metal clad and metal enclosed switchgears. This combination helps in controlling the load and voltage in the area, along with facilitating fault regulation.
Power stations: Main and sub power distribution units require these switchgears to protect various types of electrical connections. Power generation and distribution involves the use of various types of circuit breakers and surge protectors, which are generally enclosed in these switchgears.
