Normally, network floors are specialized in resolving integrated wiring systems. It is applied to office, but there's no standard in national regulation, so anti-static grounding system engineering is rarely considered. As the climate in northern China is relatively dry and it is easy to occur static electricity, so anti-static grounding system would be a better choice, but the cost increases a lot. Moreover, humidifier is needed in the northern region to increase the temperature and humidity so as to reach national standards: ambient temperature from 18℃ to 25℃, which can give away static electricity better. Anti-static grounding system has a high requirement to the ability of electrostatic prevention of the equipment. Hope clients could pay attention to the anti-static grounding system and never ignore the harm of static electricity to human body and equipments.
