Why the contact of the primary connectors must be Copper in the 0.4KV Low voltage switchgear?

Copper sheets are used as primary connectors materials in 0.4kV low-voltage drawer switchgearmainly because copper has the following advantages, which can ensure the efficient and safeoperation of electrical equipment:

1. Excellent electrical conductivity in the 0.4KV Low voltage switchgearCopper sheets are widely used in the 0.4KV low voltage switchgear primary coonectors, mainlybecause of the following advantages to ensure the efficient and safe operation of electricalequipment:In low-voltage switchgear, the current load is large, and the use of copper sheets can effectivelyensure the stability and reliability of current flow.

2. Antioxidation and corrosion resistanceCopper has good antioxidation properties and is not easy to rust at room temperature. It canmaintain good contact performance during long-term use, reduce the increase in contactresistance caused by the formation of an oxide layer, and thus ensure the long-term stableoperation of the system.There is usually an oxide film on the surface of the copper sheet, which further enhances itscorrosion resistance, especially in a humid environment. This feature is particularly important.

3.Good machinabilityCopper materials have good ductility and processability, and can be made into copper sheets ofdifferent shapes and sizes to meet the structural requirements of electrical equipment andconnectorsIn the connector structure of the low-voltage switchgear, the copper sheet can be preciselymatched and installed to ensure good contact of the and reduce problems caused by poorcontact.
