If you are searching for the variety and uses of each, Rajdhani Cables is a manufacturer with a credible reputation. Our range is based on national and international regulations and the application-specific requirements.
LT Cables for Low-Voltage Power Distribution
Low tension cables are the most common cables that you can find, as they are meant for residential, commercial, and low-power industrial use. These cables carry electrical power from the supply grid to individual loads. The quality of the conductor, insulation, and safety provisions plays a crucial role in designing LT cables.
Some of the common configurations you can explore are heat- and fire-resistant PVC-insulated cables, single core and multi core variants.
Here are the broad uses of LT cables:
- Residential electrical installations
- Commercial buildings
- Industrial Low voltage installations
- Switchgear
- Control panels
- Motor starters
- Controllers
- Instrumentation panels
- Relay connections
Power Cables for Electrical Power Transmission
Power cables are designed to transmit and distribute electrical energy from power sources to different electrical loads. Depending on the voltage level and application, power cables are available in different conductor sizes, insulation materials and constructions.
Power cables are used in residential, commercial, industrial and infrastructure applications. Their construction is selected according to the required voltage, current-carrying capacity, installation environment and mechanical protection requirements.
Common applications of power cables include:
- Electrical power distribution
- Industrial power systems
- Commercial buildings
- Power plants and substations
- Infrastructure projects
- Distribution networks
- Electrical equipment connections
Building Wires for Residential and Commercial Wiring
Building wires are commonly used for electrical wiring inside residential, commercial and other buildings. These cables are generally selected according to the voltage, current requirement, installation method and environmental conditions.
They are used to connect electrical distribution systems with switches, sockets, lighting points and other electrical equipment.
Common applications of building wires include:
- Residential wiring
- Commercial buildings
- Offices
- Shops and retail spaces
- Lighting circuits
- Switches and sockets
- Electrical panels
- Internal power connections
Armoured Cables for Added Mechanical Protection
Armoured cables are the electrical conductors to which a strong metallic layer is added. This mechanically strong layer increases the stability of the wire. It prevents the rodents and other animals from biting the wires. During installation, the unarmoured cables might break during routing, but the armoured layer protects the wire from the abrasive forces.
Steel Wire Armouring
SWA, or steel wire armouring, uses galvanized steel wire to layer the cable. It is wrapped around the insulated conductor above the inner sheath. On this layer, an outer sheath of PVC or XLPE insulation is covered.
The armoured cables are popularly used in:
- Industrial power distribution
- Commercial installations
- Infrastructure projects
- Power connections
Industrial Cables for Heavy-Duty Applications
Industrial cables are designed for electrical systems operating in demanding industrial environments. These applications can involve machinery, motors, control systems, power distribution equipment and other industrial electrical installations.
Depending on the application, industrial cables may require protection against mechanical stress, heat, moisture, chemicals or other environmental conditions.
Industrial cables are commonly used in:
- Manufacturing plants
- Heavy machinery
- Industrial power distribution
- Motor connections
- Control systems
- Automation equipment
- Industrial panels
- Infrastructure projects
Control and Instrumentation Cables
Control and instrumentation cables are used to transmit control signals and measurement signals between electrical equipment, control panels, instruments and industrial systems.
They are particularly useful in industrial environments where reliable signal transmission is required between different components of an automated or controlled system.
Common applications include:
- Control panels
- Industrial automation
- Instrumentation systems
- Process control systems
- Machinery
- Monitoring equipment
- Industrial plants
- Relay and control circuits
Fire-Resistant and Flame-Retardant Cables
Fire safety cannot be overlooked in any of the modern cables. The standard regulations increasingly expect the manufacturers to include certain safety features regarding fire accidents. Flame-retardant cables can have LSZH, HFFR, or FRLS insulation, depending on the configuration. Their applications can be found in most residential, industrial and commercial appliances and power distribution.
Fire-safety cable applications include:
- Residential buildings
- Commercial buildings
- Industrial installations
- Public infrastructure
- Electrical distribution systems
- Critical electrical installations
Data and Communication Cables
Data and communication cables are designed to transmit information and signals rather than electrical power. They are used in communication networks, computer systems and other data-transmission applications.
These cables are selected according to the required transmission speed, distance, network configuration and installation environment.
Common applications include:
- Computer networks
- Ethernet connections
- Data centres
- Office networks
- Communication systems
- CCTV and security systems
- Structured cabling installations
- Networking equipment
Solar Cables for Solar Power Systems
Solar cables are specially designed for electrical connections in photovoltaic (PV) systems. They are used to connect solar panels with other components of a solar power installation.
Solar installations are exposed to outdoor environmental conditions, so cable construction needs to be suitable for the intended installation environment and operating conditions.
Solar cables are commonly used for:
- Solar panel connections
- Photovoltaic systems
- Solar farms
- Rooftop solar installations
- Solar inverters
- DC connections in solar systems
- Renewable energy projects
Innovative Cable Varieties
Strengthening the insulation and conductor material is not the only purpose of innovations in modern cables. Here are the ways in which the electrical cables get enhanced features and performance:
Unify Conductor
In the unified cables, the bunched copper conductors are closely arranged. As there are no loose strands, the risk of power loss due to them is minimized. Low conductor resistance is the key to the longer life of unified cables. These are used in domestic and commercial wiring, appliances, terminals, and sockets.
How to Select the Right Electrical Cable
When selecting the electrical cables, it is important to identify the difference in build type, insulation used, size of cable and current carrying capacity. The application, voltage requirement, installation environment and required protection should also be considered.
- Voltage rating
- Current-carrying capacity
- Conductor material
- Number of cores
- Cable size
- Insulation material
- Mechanical protection
- Temperature and installation conditions
- Fire-performance requirements
Conclusion
Low tension cables are used in common wiring systems for power distribution and signal transmission, while armoured cables have more mechanical protection. Innovative features such as Unify copper conductor and fire-retardant insulation make the cables fit for modern installations. Power cables, building wires, industrial cables, control and instrumentation cables, data and communication cables, and solar cables serve different application requirements.
When selecting the electrical cables, it is important to identify the difference in build type, insulation used, size of cable and current carrying capacity. A leading wire and cable manufacturer like Rajdhani Cables provides a detailed chart with clear specifications.
