Not only wiring of domestic property but also electrical installation for commercial and industrial property is required. Key points include logic for control and automation technology, cable and wiring. And programming of small-scale control systems.
Smart industrial wiring is based on 3-phase power. 3-phase power allows you to place a lower workload on each connected wire and work together to give you maximum results at the same time. With 3-phase power, the wire is smaller and the motor is smaller than a typical single-phase motor. These factors allow for greater efficiency and longer lasting motors and wires.
There are four types of 3-phase electrical power:
- Common 3 wires
- Common 4 wire
- 3 Wire with hot leg
- Special 4 wire
Regardless of the 3-phase power you choose to use, you will need a voltage meter to determine the actual voltage available to you. Type does not determine this. Industrial cables usually run through metal carriers, armored cables, or a track. This box is the protective ground – never neutral wire.
Difference between industrial wiring and residential wiring
The differences between industrial wiring and residential wiring are the insulation, voltage load and installation process. Residential cables typically run through walls and attic crawling spaces in a single-phase design. And use a lower voltage due to the lower electrical load. Industrial wiring uses a three-phase design to create high output for high voltage equipment and multiple systems. Heavy work insulation protects industrial wiring from corrosive liquids or gases. Sensitive and power-hungry machinery often requires specialized, heavy-duty shops.
Insulating materials for industrial cables
Wires and cables (conductors) are insulated and protected by various materials (insulators). The type of material used is determined by the designer, taking into account the environment in which a control panel or installation is expected to operate. As well as the application of individual wires within the board.
As part of the insulating function, a material may have to withstand without failing:
- Current or temperature extremes
- Corrosion or similar harsh environment
- Higher voltage than the other circuit.
Because of these different properties and applications, it is essential to check the cable specifications to use the correct type.
