Industry has evolved with the times, and heavy-duty connectors are widely used. Let's talk about the pollution caused by such connectors.
Pollution level 1 means that the heavy-duty connector has no pollution or pollution that has no effect on the equipment. This pollution is often dry and non-conductive pollution. This situation is common in computer rooms and so on. Pollution level two, there is pollution, but for non-conductive pollution, this pollution may lead to occasional short-term conductive pollution, which occurs in residential or commercial buildings, laboratory buildings. Pollution level three, conductive pollution, or conductive pollution caused by non-conductive pollution, this occurs in the workshop or boiler room, or where there are electrical equipment or machine tools. Pollution level 4, conductive pollution continues to lasting conductive pollution, which is often caused by the environment, such as snowstorms or sandstorms, outdoor space, trains can also appear persistent conductive pollution.
All connectors cause contamination, so frequent maintenance and repairs are required during use.
