FAQ
What is the difference between a wire and a cable?
A wire is a single conductor used to carry electricity, while a cable is a bundle of wires grouped together, often with insulation around each wire, designed for carrying electrical current more efficiently.
What types of cables are used for electrical installations?
Common types of cables include single-core cables, multi-core cables, armored cables, coaxial cables, and fiber optic cables, each serving different purposes like power transmission, data transfer, and communication.
How do I choose the right cable for my project?
Selecting the right cable depends on factors such as the current rating, voltage requirements, environmental conditions, installation location, and safety standards. It’s important to consult a professional or refer to national standards.
What is the purpose of cable insulation?
Cable insulation protects the wires inside from external damage, moisture, and electrical faults. It also ensures that electrical current flows through the conductors without leakage or interference.
What is the meaning of "armored" cable?
Armored cable has an extra layer of protection made from materials like steel wires or aluminum, providing added resistance to physical damage and making it suitable for installation in rough environments.
What are the safety standards for cables?
Cables must meet specific safety standards like UL (Underwriters Laboratories), IEC (International Electrotechnical Commission), or RoHS (Restriction of Hazardous Substances), depending on their intended use and geographical location.
How can I extend the life of my cables?
To extend the life of cables, avoid overloading them, protect them from extreme temperatures, keep them away from moisture, and ensure proper installation with correct voltage and current. Regular inspection also helps.
What is the difference between a power cable and a communication cable?
Power cables are designed to transmit electricity to devices, whereas communication cables are used for data transfer (such as Ethernet cables, fiber optics, or telephone lines) and carry signals rather than electrical power.
