What are the electrical connection methods of industrial power distribution boxes?

1. Bus connection method

Busbar connection is the most common electrical connection method in distribution boxes. A busbar is a large-section conductive metal strip, usually made of copper or aluminum. Bus connection methods are divided into two types: hard bus connection and soft bus connection. Hard busbar connection connects the busbar directly to the equipment terminals and is suitable for occasions with large currents; soft busbar connection connects the busbars to equipment terminals through cable connectors and is suitable for occasions with smaller currents.

2. Cable connection method

The cable connection method uses cables as the medium for electrical connection to transmit electrical energy from the outdoor electrical distribution box to various electrical equipment. Cable connection methods are divided into direct buried cables, pipeline cables, bridge cables, etc. The cable connection method has the advantages of easy installation and simple maintenance, but the cost is relatively high.

3. Terminal connection method

The terminal block connection method is to connect electrical equipment to the electrical distribution box through terminal blocks. A terminal block is a device used to make electrical connections, usually made of copper or aluminum. The terminal block connection method has the advantages of reliable contact and convenient maintenance, and is widely used in various electrical equipment.
