Versatile and Durable Cable ConstructionEngineered with high-quality copper conductors and PVC insulation, these unarmoured cables provide robust performance and reliable protection. The flame retardant properties, combined with resistance to moisture, sunlight, chemicals, and oil, make them well-suited for diverse indoor and outdoor installations. Their flexibility and good mechanical strength ensure ease of handling and durability under varying conditions.
Flexible Installation and Customizable OptionsThese cables are applicable for a range of uses including control panels, power distribution, lightings, and general wiring. They can be installed using surface mounting, in conduits, or trunking systems. With options for different colors, sizes (from 1.0 Sq.mm to 16 Sq.mm), and core configurations (single to multi-core), users can select cable variants that best suit their specific electrical requirements.
FAQs of CU PVC PVC Unarmoured Cables:
Q: How are CU PVC Unarmoured Cables with FR/FRLS grade typically used?
A: These cables are widely used in residential, commercial, and industrial wiring for control panels, power distribution, lighting, and general electrical installations. Their flame retardant and low smoke properties ensure enhanced safety in populated environments.
Q: What are the benefits of the flame retardant and FRLS grade insulation?
A: The FR/FRLS insulation significantly reduces fire risk by inhibiting flame propagation and limiting smoke emission during a fire, enhancing safety and visibility for occupants during emergencies.
Q: When is it advisable to choose unarmoured cables over armoured ones?
A: Unarmoured cables are suitable where theres no exposure to high mechanical stress, such as indoor wiring, conduit, and trunking installations. For direct burial or areas with possible physical damage, armoured cables are preferred.
Q: Where can these cables be installed and what environments are they suitable for?
A: These cables can be installed on surfaces, inside conduits, or trunking, making them suitable for both indoor and sheltered outdoor use, thanks to their weatherproof construction and resistance to moisture, chemicals, and UV rays.
Q: What is the process for selecting the correct size and core configuration?
A: To choose the right cable, consider the current load requirements, application area, installation type, and local regulations. Consult with an electrician or refer to IS 694 standards to ensure the appropriate size (from 1.0 Sq.mm to 16 Sq.mm) and the necessary number of cores for your application.
Q: How are these cables typically supplied and in what lengths?
A: CU PVC Unarmoured Cables are available in standard 90-meter rolls or custom-cut lengths, supplied either in rolls or on drums, as per the users project specifications or bulk requirements.
