Medium voltage (MV) electrical systems are energy transmission and distribution systems that generally operate at voltage levels ranging from 1 kV to 36 kV. These systems are critical for the safe and efficient transmission and distribution of electrical energy in a wide range of areas, such as industrial facilities, commercial buildings, infrastructure projects and large residential areas. The reliability and sustainability of medium voltage systems are directly related to the quality of the electrical materials and switchgear products used. Medium voltage electrical materials and switchgear products form the backbone of energy transmission and distribution systems. The correct selection, supply and use of these products ensures that energy systems operate safely, efficiently and sustainably. The quality of the materials used in the projects, the reliability of the manufacturers and technical support services play a critical role in the performance and longevity of the systems.

Medium Voltage Electrical Equipment

The main materials used in medium voltage electrical systems are:

Cables and Conductors: Cables used in MV systems must be resistant to high voltage and have high electrical conductivity. Aluminum and copper are the most commonly used conductor materials.

Insulators: Insulators are used to ensure the safe transmission of electrical energy. Ceramic, glass and polymer insulators are commonly used in MV systems.

Transformers: In MV systems, transformers are used to reduce or raise voltage levels. There are various types such as power transformers, distribution transformers and auto transformers.

Breakers and Disconnectors: Breakers and disconnectors are used for the protection and control of MV circuits. These devices protect the system by interrupting the circuit in case of malfunction.

Switchgear Products

Switchgear products are equipment used for the control, protection and distribution of electrical energy. The main switchgear products used in medium voltage systems are:

MV Switchgears: MV switchgears are used for safe control and protection of medium voltage circuits. Metal-enclosed, gas-insulated and air-insulated switchgears are the most common types.

Relays and Protection Systems: Relays and protection systems are used to ensure the security of MV systems. These systems detect situations such as overcurrent, ground fault, short circuit and take the necessary protection measures.

Disconnectors and Breakers: Disconnectors and breakers used for on-off operations of MV circuits safely control the energy flow.

Capacitors and Reactors: Capacitors and reactors used for power factor correction and voltage control increase the efficiency of MV systems.
