What are the best ways to design electrical systems that meet durability requirements?

1 Choose the right materials

The first step is to select the appropriate materials for the electrical components, such as wires, cables, conduits, connectors, and switches. You should consider factors such as temperature, humidity, corrosion, vibration, and abrasion resistance, as well as fire and electrical ratings. For example, you may need to use stainless steel or PVC for conduits in wet or corrosive areas, or use silicone or Teflon for wires in high-temperature zones.

2 Follow the standards and codes

The second step is to comply with the relevant electrical engineering standards and codes, such as the National Electrical Code (NEC), the International Electrotechnical Commission (IEC), or the American National Standards Institute (ANSI). These standards and codes provide guidelines and specifications for the design, installation, and testing of electrical systems, as well as safety and performance requirements. You should also consult the local authorities and the facility owner or operator for any specific regulations or preferences.

3 Optimize the layout and routing

The third step is to optimize the layout and routing of the electrical system, taking into account the functionality, efficiency, and accessibility of the components. You should avoid unnecessary bends, loops, or twists in the wires and cables, as they can cause stress and damage. You should also avoid crossing or running parallel to other electrical or mechanical systems, as they can create interference or heat. You should also provide enough clearance and spacing for ventilation, insulation, and maintenance.

4 Protect from external factors

The fourth step is to protect the electrical system from external factors, such as weather, animals, or human interference. You should use appropriate enclosures, covers, or barriers to shield the components from moisture, dust, debris, or UV rays. You should also use proper grounding, bonding, and surge protection devices to prevent electrical shocks, fires, or power surges. You should also label and secure the components to deter vandalism, theft, or tampering.
