Impressive Technical Specifications of Substation Surge Arresters
Key Features:
- The product utilizes gapless technology, eliminating the phenomenon of air gap breakdown, thereby enhancing insulation durability and ensuring a rapid response to overvoltage surges. This design not only improves reliability but also reduces the risk of internal discharge, ensuring the safety of the entire system.
- Substation surge arresters support a wide voltage range from 3kV to 240kV, making them suitable for various voltage levels in medium and high-voltage substations. The device effectively protects critical equipment, such as transformers, switchgear, and control devices, from dangerous overvoltage surges.
- With a discharge current capacity of up to 10kA, the product can effectively handle direct lightning strikes or transient surges caused by switching operations. This ensures continuous operation, prevents equipment damage, and minimizes repair and replacement costs.
- Substation surge arresters are tested at the CESI laboratory – a member of STL, fully meeting rigorous testing requirements according to the IEC 60099-4 standard. This serves as clear evidence of the product’s high quality, safety, and stability throughout its operational lifespan at electrical substations.
Practical Applications
The equipment is widely used in projects requiring high reliability for the protection of medium and high-voltage power systems:
- Medium and high-voltage substations: Protect all station equipment from overvoltage incidents, ensuring continuous and safe system operation.
- Power plants and the national power transmission system: Minimize the risk of widespread power outages caused by lightning strikes or sudden surges.
- Key industrial zones and large manufacturing plants: Stabilize voltage and protect control devices, switchgear, and industrial automation systems.
- Airports, seaports, and logistics centers: Operate effectively in humid and dusty environments with a high frequency of abnormal electrical surges.
- Renewable energy infrastructure projects (wind, solar): Ensure safety for inverter systems, transformers, and electrical cabinets within energy conversion stations.
- High-tech GIS (Gas-Insulated Switchgear) or AIS (Air-Insulated Switchgear) station systems: Require surge protection devices with high durability, instantaneous response capability, and absolute reliability.
