Becoming a new vogue word across the globe, the technological development is shifting the boundaries for security and high protection of electrical control systems. As a result, a drift is marked in cabling system installed in electronic equipments that serve the purpose of protection of electronic assets in contact with varied type of environments. With this, the cable gland manufacturing is in full swing with customization, quality, unique combination of material melds and with varied inbuilt features that has become a recent buzz in the worldwide technology spectrum. This article is a technical guide to significance of cable glands. Furthermore, it answers the curiosity on the mechanism to which it protects the cables from Electromagnetic Interface (EMI)?
The worldly technical expertise in all dominant business verticals is summoned up with concentration on an improved Electromagnetic Compatibility (EMC) in the electronic instruments. Be it a weird noise in radio due to the ringing of mobile phones or electromagnetic incompatibilities in a vehicle making the drive pretty uncomfortable or other discomforts faced because of the issue of electromagnetic interface in any of the electronic control system that needs strong cable protection with tough cable gland installation having application in transportation, mines and quarries, Power plant, water works, water treatment, oil and gas, petrochemical, marine and other leading industries.
The issue of Electromagnetic Compatibily has been a great challenge since the day technology resided in our routine life and business operations. People now feel handicapped without wireless technologies like Bluetooth, GPS, WLANS and many more. The pace of using electronic devices and the electromagnetic interface is a parallel aspect affecting the smooth operations in the electronic equipment. Now it has become one of the sensitive concerns that is taken care off right from the planning stage of any type of electronic project to avoid the high cost of rework in the future.
Let’s first take a quick read to the directives on Electromagnetic Compatibility (EMC)!
An electromagnetic field occurs around each electrical device that is capable to induce voltage and currents in other electrical devices which can result into a device malfunction, failure of operations in a device or issues in functionality of the equipment. The electromagnetic influence of low and high frequency arena results in these kind of electromagnetic interferences that arises due to capacitive, galvanic and inductive forms of coupling between two electrical circuits.
Going into the depth of technicalities of how cable glands help protect cables from electromagnetic interface (EMI)!
The unwanted electromagnetic interface effects can be minimized or even curbed with an effective shielding that lessens the density of emission of interference from electrical apparatus. As one of the vital components of the cabling system, the cable glands have effective shielding features at sensitive interconnections to avoid the cross signalling and interferences in the circuitry.
The quality of shielding that makes the cable gland an effective one majorly depends on the type of shielding, electrical ground connections and shielding material used in the cable gland manufacturing. Furthermore, other importance of cable glands on security of cable from electromagnetic interface (EMI) includes lowest transfer impedance, smooth assembly and among all, its high current carrying capacity makes it rough and tough to be installed in any simple or complex environment.
The research and development unit of cable glands has been able to come up with solutions that provide full control during installation in addition to controlling the shielding thickness that can act as a key success factor to make a safety screened tap connection. The partially stripped cables with effective shielding also has good contact of cable shields that can be routed further, which is possible with a spring system for developing a good contact between shields.
Other riches of the cable glands that are best for protection from Electromagnetic Interface:
It has a protective clamping of cable shield that derives a powerful performance in delivering smallest transfer impedance with super protective shield contact. The cable connectors are designed with a tech savvy layout that shapes the contact spring, which helps the Shield to get a large clamping range. One of the specialties of cable connector with effective shielding and contact is the smooth disassembly without any kind of damage to the EMC braid. Making it a super protective gland for cable, it has resistance to torsion, two part sealing inserts and with long or short entry threads. In addition to these, it has resistance to low contact, flexible terminating methods, non stop contract pressure and high temperature stability. Other attributes of cable glands consist of resistance to highest leakage currents making it more flexible in complex situations.Thus, the new innovation in cable connectors is heading towards compression technology and EMC tapping bonding technology to raise the bar in the level of customization to varied business verticals.
