ELECTRICAL WIRE & CABLE
[CODE NO.4054]
Wire is used to carry the current from one place to another A wire is a single conductor (material most commonly being copper or aluminium) while cable is two or more insulated wires wrapped in one jacket. Multiple conductors that have no insulation around would be classified as a single conductor.
TYPES OF ELECTRICAL WIRES
There are two main types of wires: solid or stranded.
A solid wire is a single conductor that is either bare or insulated by a protective colored sheath. It offers low resistance and is perfect for use in higher frequencies. When inside a covering there are many thin strands of wires twisted together, it is called a stranded wire. Stranded wires are used where flexibility is important because which the wire can be used for a longer period. This type of wire have larger cross-sectional area than solid wires for the same current carrying capacity. Stranding is process of twisting together of small wires to form a single larger conductor. Used to provide flexibility, ease of handling and vibration resistance.
Copper Wire
Copper Wire is a single electrical conductor manufactured out of Copper Ore. This widely used conductor can either be insulated or uninsulated. Having a moderate conductivity, it’s used to transfer electricity with low voltage. Electrical wiring in buildings is the largest market for the copper industry worldwide. As per estimation, around half of the copper mines is consumed in manufacturing electrical wire and cable conductors.
PROPERTIES
Properties of Copper Wire:
• Tensile Strength
• Electrical Conductivity
• Strength and Ductility combination
• Creep resistance (it doesn’t change much due to heat)
• Corrosion resistance
• Co-efficient of thermal expansion
• Ease of installation
• Thermal conductivity
• Ability to be soldered
ELECTRICAL CABLE
A cable is defined as the set of conductors, insulators, sheaths and armor protection or shielding, specifically built to carry the current both for energy transportation and for signal transmission.
PVC COPPER CABLE
PVC insulated cables & wires are the ultimate medium for the distribution of electricity. The PVC cables are used for the power distribution in all types of electric wiring, control cables, telephone cables and signaling in Railways. The PVC cable has mostly replaced VIR and CTS cable in domestic as well as industrial wiring due to its long life, moisture resistance, etc
The individual insulated conductors are covered with PVC coatings providing additional electrical and mechanical protection. The cables are suitable for use in sub-station, distribution systems, industrial installation, house wiring and street lighting, etc.
House wire is the simplest of cables and most basic in its construction, manufacture and use. It consists of only two components, viz. conductor (mostly copper) and insulation (mostly PVC) involving three operations – wire drawing, stranding, bunching and extrusion. Before the advent and subsequent extensive use of vinyl compound as insulating materials, vulcanized rubber was most commonly used insulating material for domestic wire as it was for other types of cables. It served the industry and the users very well for several decades until replaced by PVC (Poly Vinyl Chloride).
Property
1. The long-term permissible operation temperature of the conductor shall not be higher than 70℃.
2. Conductor maximum short circuit ((less than 5 second) temperature shall not be higher than 160℃.
3. The cable is not limited by drop in level when being laid, and the environment temperature shall not be lower than 0℃.
4. Perfect chemical stability, resistant against acids, alkalis, grease and organic solvents, and flame retardance.
5. Light weight, perfect bending properties, installed and maintained easily and conveniently.
Application
With the characteristics of stable capability, advanced technology, broad material resources, low price, good flexible and easy to lay and maintain, the PVC Insulated and Sheathed Power Cable are suitable to be laid for distribution line with A.C.50HZ and rated voltage up to 1kV.
