Understanding mechanical testing for cable longevity

What is the purpose of mechanical testing? Power cables, typically installed underground, in ducts, or on overhead structures, are often subject to mechanical stresses such as tension, compression, bending, and twisting. Hence it is important that cables are put through stringent tests to ensure they can withstand the mechanical stresses that they will be subjected […]

RS485 vs RS422 Similarities and Differences

In data communication, there are low-frequency and high-frequency communication. For low-frequency data communication, 2 wire protocols are commonly used: RS422 and RS485. Wire protocols are guidelines for the transmission of data from point to point. Both of these “RS” protocols, RS422 and RS485, are also known as TIA-422-B, and TIA-485-A respectively. Cables following these protocols

Understanding Variable Speed Drive Cables

Power and control cables transmit and distribute electrical energy in various applications. In cases where Electromagnetic Compatibility (EMC) is required, Variable Speed Drive (VSD) cables become an attractive choice. What are VSD Cables? VSD cables are 3-core cables specially designed to limit the effects of Electromagnetic Interference (EMI). They are screened, heavy-duty cables for machinery that requires

SS 299:2021 Updates – Fire Resistant Test Standard

In our previous Keystone Academy blog, ‘Fire resistant test standards-explained!‘. we introduced the differences among the 3 common LSZH FR test standards. In Singapore, Fire-resistant (FR) cables undergo tests given by the Singapore standard, SS 299. SS 299:2021 standards specifies the requirements of FR cables relating to characteristics required to maintain circuit integrity and the

H07RN-F Neoprene Cables: For Heavy Duty Use

Power cables are ubiquitous for different industrial applications. In cases where ordinary power cables cannot operate under certain harsher conditions, H07RN-F neoprene cables become an attractive choice. What does H07RN-F mean? H – conformity to harmonized standards (set by CENELEC that standardizes electrotechnical specifications)07 – voltage rating is 450/750VR – EPR insulationN – PCP jacketF – Flexible
