Time: 2022-11-02 Hit: 54

Project Background


CS Vocational Technical College is located at hilly terrain in Hunan CS. It is subtropical zone continental climate with abundant rainfall, four seasons, the annual thunderstorm days between 34.9 ~ 71.3 days, and it belongs to high minefield.

The college’s lightning protection design of security monitoring system is not perfect, and it was located in lightning strike prone areas, power supply system, monitoring system, network data system of security monitoring has suffered different extent losses due to lightning strike.

Design of lightning protection scheme

After receiving customer’s demand, WPX do a field visit to the school environment. Security surveillance cameras are widely distributed, the gathering image has a long monitoring distance when transmit to centre computer room, transmission lines and outdoor equipment are vulnerable to suffer lightning strike.

After know the detailed reason for the damage of the equipment, WPX made overall integrated lightning protection scheme which include sports field monitoring area, teaching area monitoring, dormitory area monitoring and other areas, according to each region’s power supply system, monitoring system, data interchange system, WPX also customized few surge protectors, and finished the installation & arrangement of integrated lightning protection system with the cooperation of college’s staff.
