Their insulation is color coded and made of high quality PVC, the wire itself is made of high conductivity copper. They provide solid, stranded, circular annealed, bare or tinned copper wires of various sizes like 1.5 sq. Are known to be the best in the business.

But the ones from Prime Cables Industries Pvt. No matter what wire you use, always choose the high quality ones, as even if you choose shielded cables for the entire house, it won’t make sense if it’s shield is low quality and could leak the electromagnetic interference.įor the shielded and unshielded cables, there are very limited number of quality products in india. Unshielded wires contain only the twisted pairs with the main outer sheath/insulation. Unscreened Twisted Pair Cables, on the other hand, are easy to manufacture and also cost effective, as the sheath/shield is mostly made of pure aluminium or copper, which in turn, reduces the cost of the wire. The major reasons why these wires are not always used are, one, they are expensive to manufacture, and two, they are less flexible than their unshielded doppelgangers. Not only the wire but the couplers and jacks used in these wires are carefully shielded in order to prevent any possible shield leak, whatsoever. The higher quality shielded wires consist of a drain wire, which carries the effects of electromagnetic interference to the ground, and dissipates the excessive noise to the ground. Hence for these applications, shielding is an important element. These devices cause electromagnetic interference and can produce “noise” during current or even data transmission. Now, how this factor is decided if we want to use a screened or unscreened type of wire? The answer is where the wire is laid, whether it coincides with elements like motors, generators, air conditioners or even printers or fluorescent lamps. This screen helps in reduction of electromagnetic interference. Screened Wires are those twisted pair cables that have either copper wire braid, aluminum Mylar tape or aluminum wire as a screen between different twisted pairs inside the main insulation. Here, we tend to break down the differences between these two cables. Among the cables, there’s a long going debate on the use of shielded or unshielded cables. Despite these limitations, many local and long-distance telephone companies are replacing existing telephone lines with fiber-optic cables, enabling them to offer fiber Internet access to home and business users.When installing or upgrading your home, the question often arises, “Which wire should be used where?” This may seem like a small question, but is in fact a very intricate matter for efficiency as well as safety.
TWISTED PAIR CABLE IN HINDI INSTALL
Smaller size (much thinner and lighter weight).ĭisadvantages of fiber-optic cable are it costs more than twisted-pair or coaxial cable and can be difficult to install and modify. Less susceptible to noise (interference) from other devices such as a copy machine.īetter security for signals during transmission because they are less susceptible to noise. Inside the fiber-optic cable, an insulating glass cladding and a protective coating surround each optical fiber.įiber-optic cables have the following advantages over cables that use wire, such as twisted-pair and coaxial cables:Ĭapability of carrying significantly more signals than wire cables. Each strand, called an optical fiber, is as thin as a human hair. The core of a fiber-optic cable consists of dozens or hundreds of thin strands of glass or plastic that use light to transmit signals. Noise is an electrical disturbance that can degrade communications. The wires are twisted together to reduce noise. Each twisted-pair wire consists of two separate insulated copper wires that are twisted together. Twisted-pair cable consists of one or more twisted-pair wires bundled together. One of the more commonly used transmission media for network cabling and telephone systems is twisted-pair cable. Inside the fiber-optic cable, an insulating glass cladding and a protective coating surround each optical fiber. While the core of a fiber-optic cable consists of dozens or hundreds of thin strands of glass or plastic that use light to transmit signals. Summary: Difference Between Twisted Pair and Fiber Optic Cable is that Twisted-pair cable consists of one or more twisted-pair wires bundled together.
