In this article, Arian Abhar’s wire and cable explained about the shielded spray control cable. Stay with us.
Spray control cable
The control cable of Afshan is a multi-stranded cable that is formed by twisting several strands of wire. Each of these wires transmit control, protection or measurement signals in the network of control circuits and send signals to control industrial equipment. Spray cables are mostly used in dry and wet areas and when more flexibility and softness with moderate mechanical properties are required. Spray control cables are also used to connect components of production line devices. Also, Afshan control cable is used in the transmission of analog signals (currents passing through the equipment) and digital signals (such as passing control commands in the electrical panel) and opening and closing the switches. In general, sprinkler control cables:
For control and connection in machines
To control conveyor belts
For control and connection in the production line of factories and machine tool industries
For control and connection in advanced assembly lines of automatic equipment
They are used to withstand moderate mechanical stress. These flexible cables have a thermal range (in the conductor) of 70+ degrees in normal operation and up to 150+ degrees in short circuit, and on the cable surface in the bending state between -5 and +50 degrees and in the fixed state between -40 to 70+ degrees are usable. Spraying control cables are among the most widely used cables in machinery and industries, which will be discussed in more detail below.

Shielded sprinkler control cable
The use of braided or braided copper is an important distinguishing feature of shielded sprinkler control cables. As it was said, Afshan cables are often used in places that require more flexibility and moderate mechanical properties. In addition, shielded sprinkler control cables are used when there are magnetic fields, and the use of shields or braids in shielded sprinkler control cables greatly reduces the effect of noise and electromagnetic waves without affecting the ability to soften and Reduce its flexibility. These cables are available in the market with a working voltage of 500/300 volts and a test voltage of 2000 volts alternating current.

Spray control cable with PVC coating
As it was said, softness and flexibility are very important in sprinkler control cables. Having a PVC cover in these cables adds to their flexibility. PVC is the term for polyvinyl chloride, which is a type of plastic polymer and is one of the most widely used and valuable products of the petrochemical industry, which is widely used in the industry, especially in the construction industry. PVC is made through the polymerization of monoparvinyl chloride. PVC is a very good insulator of electricity, and for this reason, it is used in many wires and cables, including control cables. The following are the advantages of PVC-coated sprinkler control cable.
Recyclability
Good flexibility and flexibility
Easy production process and reasonable price
Good insulation resistance
In addition, PVC covers also have disadvantages that need to be taken into account. Including:
In case of ignition, poisonous hydrogen chloride gas is emitted from them, which causes damage to the eyes, skin and causes breathing problems.
During a fire, they create a lot of smoke that causes vision impairment.
in the end
Reviewing what was said in this article makes us know; Afshan control cables are formed by twisting multiple strands of wire and each of these strands transmits control, protection or measurement signals in the network of control circuits and sends signals to control industrial equipment. Afshan cables are used in dry and wet areas and mostly when more flexibility and flexibility with moderate mechanical properties are required. Shielded sprinkler control cables have a cut or braided copper, which is their distinguishing feature, and they are used when there are magnetic fields, and the use of a shield or cut in shielded sprinkler control cables causes the effect of noise and waves to a large extent. Electromagnetism can be reduced without decreasing their flexibility. As we said, it is very important to be soft and flexible in sprinkler control cables. The use of PVC sheath in these cables increases their flexibility compared to other sheaths.
