Series | YH5WX |
Description:
35 - 220kV Suspended Composite - Housed Metal Oxide Surge Arresters are vital protective devices designed for medium to high voltage power systems ranging from 35kV to 220kV. They are suspended and installed in places such as transmission lines, substations, and near key power equipment like transformers and circuit breakers. With composite housings (usually made of silicone rubber) and advanced metal oxide varistor (MOV) technology, these arresters can effectively suppress overvoltages caused by lightning strikes, switching operations, and system faults. By diverting surge currents to the ground and clamping the voltage to a safe level, they protect the power system equipment from damage, ensuring the stable and reliable operation of the 35 - 220kV power grid.
Features:
Wide Voltage Adaptability:It is specifically designed for 35kV to 220kV medium and high voltage power systems, with rated voltages that precisely match the requirements of different voltage levels in the grid. This allows it to provide effective overvoltage protection for various parts of the power system within this voltage range.
Suspended Installation Design:The suspended installation method saves space and is suitable for occasions where vertical installation space is limited, such as on transmission line towers. It can be easily integrated into the existing power system structure without occupying too much ground or equipment space, facilitating installation and maintenance.
Excellent Composite Housing:The composite housing made of silicone rubber has outstanding performance. It has good hydrophobicity, which can prevent moisture and pollution accumulation, reducing the risk of flashover. It also has strong resistance to aging, ultraviolet radiation, and extreme temperature changes, ensuring stable operation in harsh environmental conditions.
Strong Surge Withstand Capacity:It can withstand large surge currents caused by lightning and switching operations, effectively protecting the connected power equipment from the impact of overvoltages. This strong surge withstand capacity ensures the reliability of the power system even in severe weather or frequent switching operations.
Low Maintenance Requirements:The composite housing is not easy to be damaged and has a long service life. It does not require frequent maintenance and overhaul, reducing the operation and maintenance costs of the power system. At the same time, the stable performance of the MOVs ensures that the arrester can work reliably for a long time.
Compliance with Industry Standards:It meets relevant international and industry standards, such as IEC 60099 - 4 and ANSI/IEEE C62.11. This ensures that the arrester has good compatibility and interchangeability, and can be used in conjunction with other power equipment in the power system to ensure the safety and stability of the entire system.
