Ready Board, in the product manuals of many distribution cabinets, Ready Boards and other electrical equipment, we can often see the requirements for environmental conditions, such as the requirements for air temperature and humidity of GGD AC low-voltage distribution cabinet: the ambient air temperature is not higher than + 40 ℃ and not lower than - 5 ℃. The average temperature of 24h shall not be higher than + 35 ℃. The relative humidity of surrounding air shall not exceed 50% at high temperature of + 40 ℃.

Higher relative humidity is allowed at lower temperature. (for example, 90% at + 20 ℃), so why is the distribution cabinet so strict on air temperature and humidity? Today, I'll reveal the impact of air temperature and humidity on electrical equipment. SMC is a new material. Although it has many advantages, the price is also relatively high.

However, we can also choose different shell materials according to the purpose of Ready Board products. As a, we can provide distribution cabinet shells of various materials according to customers' needs to meet all customers' requirements. High humidity reduces the insulation strength of electrical equipment. On the one hand, the humidity is too high, which reduces the insulation performance of the air. Many places in the switchgear are insulated by air gap.

On the other hand, the moisture in the air is attached to the surface of insulating materials, which reduces the insulation resistance of electrical equipment, especially for equipment with long service life. Due to the dust inside to absorb moisture, the humidity will be more serious and the insulation resistance will be lower. The leakage current of the equipment increases greatly, even causing insulation breakdown and accidents.

In addition, the computer network equipment in the Ready Board requires about 45% humidity in the air during operation. Once the humidity standard in the air exceeds this value, the working state of the network equipment may become unstable, and the network equipment may be damaged at any time.
