ABB MWD-15 Surge Arrester Product Introduction

General Description: The ABB MWD - 15 is a silicone - rubber - insulated, gap - less metal - oxide surge arrester designed to protect electrical equipment in AC power systems from over - voltage surges. It is part of the MWD series, which is widely used in medium - voltage and high - voltage applications.
Technical Characteristics
Rated Voltage: 15 kV, suitable for systems with a nominal voltage of 10 kV.
Continuous Operating Voltage: It can continuously operate at a voltage of up to 12 kV, ensuring reliable performance under normal operating conditions.
Nominal Discharge Current: With a nominal discharge current of 10 kA, it has the ability to handle large - amplitude over - voltage surges caused by lightning or switching operations.
Residual Voltage: When discharging, it can limit the residual voltage to a relatively low level, effectively protecting the connected electrical equipment. For example, the residual voltage at 8 / 20 μs wave shape may be around 42 kV.
Excellent Non - linear Characteristics: Using metal - oxide (MO) resistors as the core component, it shows excellent non - linear volt - ampere characteristics. Under normal voltage, the resistance is extremely high, and the leakage current is only in the micro - ampere range. When an over - voltage occurs, the resistance decreases rapidly, allowing a large current to pass through and discharge the over - voltage energy.
Environmental Adaptability
Temperature Range: It can operate normally in the ambient temperature range from - 60℃ to + 40℃, suitable for various harsh natural environments.
Other Environmental Factors: It has certain resistance to humidity, pollution, and mechanical vibrations, ensuring reliable operation in different field conditions.
Applications: The MWD - 15 surge arrester is mainly used in 10 kV AC power systems to protect equipment such as transformers, switchgear, cables, and motors from over - voltages caused by lightning strikes, switching operations, and other factors. It is suitable for both indoor and outdoor installations, providing effective protection for power distribution systems.

List of Some Models in the MWD Series

MWD-03: Rated voltage is 3 kV, suitable for lower - voltage AC systems.
MWD-04: With a rated voltage of 4 kV, it is often used in some low - voltage distribution systems.
MWD-06: The rated voltage is 6 kV, which is applicable to certain medium - voltage applications.
MWD-08: Designed for 6 kV voltage level systems, it has different technical parameters compared to MWD - 06 to meet specific application requirements.
MWD-27: Has a rated voltage of 27 kV, which is suitable for higher - voltage medium - voltage systems, with parameters such as Uc 27 kV / Ur 33.8 kV / 50 / 60 Hz.
