What environmental pollution level needs to be switched to heavy-duty connectors?

Heavy-duty connectors, also known as HDC heavy-duty connectors, aviation plugs, are widely used in construction machinery, textile machinery, electric power, automation and other equipment. The advanced nature of the heavy-duty connector in terms of structural design and material use makes the connector outstanding in terms of electrical performance. The reliability of the electrical connection system is beyond the reach of ordinary connectors.

The application environment of the device has a great influence on the conductive environment of the connector. We generally divide environmental pollution into four levels. The higher the pollution level, the higher the requirement for the pit pollution capability of the connector. Because pollution will affect the electrical conductivity of the pins, and affect the surface insulation performance together with humidity.

Pollution level 1: No pollution or only dry non-conductive pollution occurs, and the pollution has no effect. Such as computer room and measuring equipment.

Pollution level two: Only non-conductive pollution occurs, but it must be expected that temporary conductive pollution will occasionally occur due to condensation. Such as residential buildings, commercial buildings, laboratories, and precision machinery workshops.

Pollution level 3: Conductive pollution or dry non-conductive pollution is conductive pollution due to expected condensation. Such as unheated warehouses, workshops or boiler rooms and electrical equipment or machine tools of the unit. The heavy-duty connector is designed according to this degree of pollution.

Pollution level four: cause persistent conductive pollution, such as caused by conductive dust or rain and snow. Such as roof equipment in open air or outdoor spaces, trains or trams. The connectors of these parts must use heavy-duty connectors and frequent maintenance to extend the service life of the connectors and ensure the safety of the equipment.
