Pollution Level Of Heavy-duty Connector Core Parameters

Hello everyone, many friends often see "pollution level" when choosing heavy duty electric cable connectors core and checking heavy duty automotive electrical connectors parameters. Now I will introduce the parameter heavy duty 12v connectors to you.
The following categories meet. heavy duty 12 volt connectors The measurement of equipment is related to environmental conditions. Possible pollution will affect its conductivity and affect the surface insulation performance together with humidity. 12v heavy duty connector The degree of pollution will affect the structure of the component through the creepage distance. heavy duty crimp connectors The degree of pollution is defined as an unprotected exposed isolation layer according to environmental conditions.
Pollution level 1: No pollution or only dry non-conductive pollution occurs, which has no effect. Such as computer rooms and measurement Equipment.
Pollution level 2: Only non-conductive pollution occurs, but condensation must be expected to cause occasional short-term conductive pollution. Such as residential, commercial buildings, laboratories, precision machinery workshops.
Pollution level 3: There is conductive pollution or dry non-conductive pollution becomes conductive pollution due to expected condensation. Such as unheated warehouses, workshops or boiler rooms, as well as electrical equipment or machine tools of units. Some heavy duty waterproof electrical connectors are designed according to this pollution level.
Pollution level 4: heavy duty 2 pin connector causes persistent conductive pollution, such as caused by conductive dust or rain and snow. Such as equipment on the roof of open air or outdoor spaces, trains or trams.
