Question

This type of cable consists of 100 pairs of copper wires in a single bundle (containing 200 wires). These wires use the same coloring scheme as 25 pair wires, repeated 4 times.

Each bundle of 25 wires is often wrapped together with a colored nylon string to help separate wires of the same color. This is called __ block

Answer 1

A "100-pair cable" consists of 100 pairs of copper wires bundled together. It's divided into four groups with distinct color schemes, using nylon string for identification. Copper's conductivity makes it ideal for electrical wiring with essential color-coding for safety.

Step-by-step explanation:

The type of cable in question is called a "100-pair cable" which includes 100 pairs of copper wires bundled together, making it a total of 200 individual wires. This bundle is divided into four sets of 25 pairs each, with each group having its unique color scheme for easy identification. To help distinguish between wires of the same color, a colored nylon string is used to bundle and separate each set.

Copper is widely used as the material of choice for electrical wiring due to its excellent conductivity. In electrical outlets, the insulation color-coding is important for identifying live/hot, neutral, and ground wires to ensure safe and proper electrical connections. This practice stems from the need to prevent electrical hazards by correctly wiring devices.
