Shielded cable and the characteristics of the shield in the cable:
Shielded cable is a cable with a simple base structure plus a layer or layers woven of various metals called shields, which are used to protect the content and information of the cable against possible electrical and mechanical disturbances of the cable and reduce the possibility of cable errors. will be
The used shield material is often made of copper metal and rarely of aluminum metal, both of which have high conductivity. In short, the shield makes the cable we use work correctly.
Shielded cable and the characteristics of the shield in the cable:
One of the most important means of energy and data transmission in today’s world is various cables. Today, electrical energy is the most consumed energy in the world and no part of the world can be imagined without it. Transmission of electrical energy and data transmission is not possible without electrical cables, such as shielded power cable. Shield means shield in English. In fact, shielded cable means a cable that has a protective shield made of copper or other material inside the cable.
Shielded power cables are used in power distribution boards, power plants, household electricity meters, street lighting, etc. Also, shielded power cable can be used underground, in water and anywhere that requires more electrical and mechanical protection. Arin Abhar Wire and Cable Industries Complex is one of the manufacturers of all kinds of shielded cables, which has been active in this field for years.
Application of protective shield in shielded power cable
When all kinds of cables are placed next to high power cables and electrical noises, they cannot transmit data fully and many signals are transmitted half-effectively. The presence of copper shields controls the intensity of the voltage and makes a stable voltage available in any situation. Another use of the shield is to reduce the intensity of radio disturbances and electric shocks. Also, shielded cable is used in open space, under water and underground, which causes rapid wear of cables.
Due to the efficient characteristics of shielded cables, these cables are widely used in the field of electrical and electronic industries, and for power transmission in medium and high voltage networks, as mentioned above, the presence of shields in high voltage cables is necessary. . Shielded cables are installed both underground and aerial. These cables have high resistance and prevent electrocution when they hit the ground or against mechanical pressure. Shielded cables are used in various applications, including fire alarm sensors, laboratory devices, and as an interface between components of a system in production lines.
Types of shielded cables available in the electricity industry:
These cables are used in most matters related to electricity. Shielded cables are made according to existing principles and standards in different types and sizes, which are divided into the following general categories:
Shielded power cable or NYCY
Shield is one of the structural requirements of power cables based on their performance. The shield causes the double resistance of the power cables, and this resistance is the reason for the use of shielded power cables in power plants and street and road electrification. The number of wires in the shielded power cable ranges from one to 61 strands and even more. Is. Single strand shielded power cable is one of the types of shielded cables which, as the name suggests, has one strand of wire. The use of single strand shielded power cable is similar to the types of shielded power cable. But the price of single-strand shielded cable is lower than its multi-stranded types.
Characteristics of shielded power cable
*Voltage: 600 to 1000 volts.
* Conductor: wire annealed or semi-alloyed copper.
*Insulation: polyvinyl chloride and compound A.
*Shield: copper wire.
* Coating: PVC.
Shielded sprinkler control cable or NYSLCY
The use of shields in control cables is necessary for accurate and correct transmission of cable signals. Control cables are a type of weak pressure cables, and not using a shield will bring the opposite results of using a shield, and the most important difference of the control cable is Shielded with other types of shielded power cable is the use of braided or braided copper in it. The copper weave in the shielded sprinkler control cable greatly reduces electromagnetic waves and noises, but keeps its flexibility intact. The price of Shildar Afshan cable, like other cables, is determined according to the number of strands used in it.
Features of shielded spraying control cable
*Voltage: 300 to 500 volts.
* Conductor: Mes Afshan.
*Insulation: PVC compound.
*Shield: woven copper.
* Coating: PVC.
Sheldar and wire cable:
The shield of the braided cables is made of copper metal, and it is one of the shielded cables in the control panels to ensure the accuracy of the accurate transmission of cable information. The shield used in wire cables is for accurate and error-free control of fluctuations against strong voltage fields around the cable. These shielded cables have a lower resistance level compared to Afshan shielded cables.
Suggested study: wire and semi-expanded wires
Shielded low voltage cable
Shielded weak pressure cable is used to measure control signals in computer systems and control equipment of industrial machines and conveyors. These cables can be installed outdoors, underground or inside the channel. One of the technical characteristics of shildar low pressure cable is its resistance to ultraviolet rays and vermin.
Technical specifications of shielded low voltage cable
Voltage: 1.8 to 3 kW.
Conductor: Uncoated annealed copper.
Insulation: XLPE or PVC cross-linked polyethylene.
Shield: copper wire or tape.
Coating: PE or PVC.
Shielded cable with glass coating
The shielded cable sheath is made of glass-coated PVC with good flexibility and tinned copper. This cable prevents the penetration of waves in environments where there is a possibility of penetration of magnetic waves.
Shielded power cable with copper conductor and XLPE insulation
Shielded power cable with copper conductor and insulation is used inside or outside the facility, in the canal or in the ground to supply energy to industrial environments and local power networks. XLPE insulation in this type of cable has a higher temperature resistance than PVC.
Features of shielded power cable with copper conductor and insulation
*Voltage: 600 to 1000 volts.
* Conductor: copper.
*Insulation: XLPE.
*Shield: copper wire, with or without helix copper tape.
* Coating: PVC.
In today’s world, shielded power cable is one of the main tools in industries that are related to the transmission of electrical energy and data transfer. Every moment in the world, hundreds of millions of information are transferred through cables, and shielded power cable is one of the most useful. If your job is related to electrical, telecommunication or computer industry, you need to buy shielded cable. Arian Abhar Wire and Cable Industry Complex supplies all kinds of shielded power cables to the market with the help of the most up-to-date technology in the world. Contact us to buy the shielded spray control cable and to know the price of the shielded cable.
General result: the use of shield in cables improves the performance and signal transmission of cables.

The price of different types of shielded cables and the factors determining the price:
One of the frequently asked questions of the buyers is the final price of the cable. We are going to provide useful information on the selling price of cables. Shielded cables are compared to unshielded cables, usually due to the use of more and more expensive raw materials and more weight. Includes more costs.
The material of the shield is usually copper and aluminum conductive metals, which is one of the factors that increase the price of the cable. Not all shielded cables are offered at the same price, and according to some cases, they do not have the same prices. One of the most important things is the type and quality of raw materials May it have a significant effect on the price of cables in the supply markets.
Among other factors, fluctuations in the domestic market and fluctuations related to foreign markets, as well as other factors affecting the price of cable, which finally send the cable to the market with the final and standard price.
