Types of Electrical Cables ITI Electrician Motilal Bhoye

Twisted Pair Cable: Consists of two conductors twisted together to reduce electromagnetic interference (EMI), commonly used in telecommunications.

Coaxial Cable: Contains a central conductor, surrounded by a dielectric insulator, a conductive shield, and an outer insulating layer. Ideal for high-frequency signals like TV and internet.

Fiber Optic Cable: Uses strands of glass or plastic to transmit data via light pulses, offering high bandwidth and immunity to EMI, commonly used in telecommunications and networking.

Multi-Conductor Cable: Contains multiple insulated conductors within a single cable, used for applications requiring multiple signals or power distribution.

Single-Conductor Cable: Consists of a single conductor surrounded by insulation, commonly used for power distribution.

Ribbon Cable: Features multiple parallel conductors flatly arranged in a ribbon-like structure, often used for internal computer connections.

Armored Cable: Contains a protective metal layer to shield against physical damage, commonly used in industrial and outdoor applications.

Direct Burial Cable: Designed for underground installation without conduit, typically features extra insulation and protection against moisture.

Fire-Resistant Cable: Constructed with materials that resist fire propagation, commonly used in buildings where fire safety is critical.

Thermostat Wire: Specifically designed for low-voltage control circuits, commonly used in HVAC systems and thermostats.
