Functionality
Circuit interruption: The ZW7-36 is designed to safely interrupt fault and normal currents in the electrical system.
High arc suppression: Utilising vacuum technology, these circuit-breakers offer superior arc-quenching capabilities, ensuring safe operation and minimal maintenance.
Outdoor durability: Designed for outdoor use, they are resistant to weather conditions such as rain, dust and temperature fluctuations.
Service and installation conditions:
Ambient temperature: Equipment should operate in environments with ambient temperatures ranging from -30°C to 40°C. For special orders requiring operation at temperatures above 40°C, please contact us in advance.
Altitude above sea level: The installation should not exceed an altitude of 1000 metres. Installations above 1000 metres should be specified in advance.
Humidity: The relative humidity should not exceed 95% on a daily average and 90% on a monthly average.
Wind pressure: The maximum permissible wind pressure is 700 MPa at a wind speed of 0 to 5 m/s.
Sunshine intensity: The maximum permissible solar irradiance is 0.1 W/cm² under a wind speed of 0 to 5 m/s.
Maximum daily temperature variation: The equipment should be able to withstand a daily temperature variation of up to 25°C.
Earthquake intensity: The installation site should be located in areas with a maximum earthquake intensity of up to 8 degrees on the Richter scale.
Application Locations
Urban distribution networks: Where reliability and safety are paramount, suitable for use in heavily populated areas.
Rural power supply: Ideal for remote areas where the environment is harsh, it provides consistent power.
Industrial facilities: Used in industries where high standards of reliability and safety are required to ensure an uninterrupted supply of electricity.
Substations and grid connections: Indispensable for controlling and protecting power flow in and from substations and grid interconnections.
