Questions regarding the prices of equipment with different protection and explosion-proof ratings
Thread Content
I wonder if colleagues in the electrical field are aware of any approximate comparisons regarding the prices of equipment with different protection and explosion-proof ratings? For example, what is the price difference between DIICT1 and DIICT2 devices?
The prices produced by different manufacturers vary, but one thing is certain: the higher the explosion-proof rating, the higher the price.
The lower the grade, with fewer manufacturers using it, the more expensive it is. No one produces it, and even if it is produced, there’s no one to buy it, so the manufacturers go bankrupt
What you’re referring to is simply the difference in the maximum temperature allowed for explosion-proof equipment: the surface temperature of T1 must not exceed 85 degrees, while that of T2 must not exceed 135 degrees
The higher the explosion protection rating, the more expensive it is. The explosion-proof rating of the equipment must be determined based on the specific installation environment; the higher it is, the better, but it is sufficient as long as the explosion-proof requirements are met.
Yes, the price varies depending on the requirements~
The gap is not very large; the larger gaps exist between IIA, IIB, and IIC. The surface temperature of T1 is no higher than 85°C, while that of T2 is 135 degrees Celsius. These generally meet the standards; no additional anything is needed, so the price difference isn’t significant.
It’s difficult to specify precisely; you can inquire about the quotes from several manufacturers to get an idea. It is recommended to choose manufacturers with a good reputation and strong capabilities.
Reply to 4# jiang3151 regarding the classification of ignition temperatures: After checking, it is as follows: T1: Ignition temperature t>450℃; T2: Ignition temperature 300
The price of explosion-proof equipment is determined not only by different protection levels and explosion-proof ratings, but also by the manufacturer; there is a significant difference between high-quality manufacturers and those of lower quality.
