In terms of electrical practice in ships, materials and conductors play a crucial role in ensuring the smooth operation of all electrical systems onboard. Here's a step-by-step description:

1. **Materials**: The materials used in shipboard electrical systems need to be robust and resistant to the harsh marine environment. This includes resistance to saltwater corrosion, extreme temperatures, and high humidity. Common materials include copper, which is used for its excellent conductivity, and various types of insulating materials such as rubber, PVC, or XLPE to protect the conductors and prevent electrical shorts.

2. **Conductors**: Conductors are the physical medium through which electrical current flows in a circuit. In ships, these are typically made of copper or aluminum due to their high conductivity. The size of the conductor is determined by the current it needs to carry, with larger conductors being used for higher currents.

3. **Cabling**: Cables used in ships are often multi-core, meaning they contain multiple conductors within a single cable sheath. This allows for the transmission of multiple electrical signals or power lines within a single cable, saving space and making installation easier.

4. **Protection**: All conductors in a ship are protected by some form of circuit protection, such as fuses or circuit breakers. This is to prevent damage to the conductors in the event of an overload or short circuit.

5. **Installation**: Conductors are installed in such a way to minimize the risk of damage. This includes using cable trays and conduits to protect the cables, and ensuring that cables are not subject to excessive tension, bending, or physical damage.

6. **Maintenance**: Regular maintenance is crucial to ensure the continued safe operation of the ship's electrical systems. This includes checking for signs of wear or damage, testing for correct operation, and replacing any components as necessary.

In conclusion, the materials and conductors used in shipboard electrical systems are carefully chosen and installed to ensure they can withstand the harsh marine environment and provide reliable operation of all electrical systems onboard.
