In our previous Keystone Academy blog, "RS485 vs RS422", we introduced the similarities and differences between the 2 wire protocols, RS485 and RS422. Though similar, the 2 wire protocols are not the same. After knowing their differences, you may be wondering how to select a suitable signal cable. Here, we have distilled the key considerations to look into: Insulation Screening ..read more

The oil and gas industry is hazardous as it is prone to explosions that occur in the presence of 3 substances: flammable gas or dust, oxygen, and an ignition source. Hence, to prevent explosions from occurring, we need to ensure that these 3 substances are not present at the same time. Conversely, as both flammable gas and dust are indispensable in the oil and gas industry, and oxygen is a necessity, the determining factor lies in the prevention of ignition sources ..read more

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 ..read more

Power and control cables are used to 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 ..read more

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, SS299 ..read more

A cable conductor is the basic component of electrical cables. It refers to the metallic wire or wires that carry the electrical signal through the cable. Here, we examine the four different Copper (Cu) conductor categories, namely Class 1, Class 2, Class 5, and Class 6 ..read more

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 ..read more

In search of a clean and sustainable energy source for the future, solar remains the most promising renewable energy source for Singapore and for most of the South East Asian countries. Singapore aims to harness 1.5 gigawatt-peak (GWp) of solar energy by 2025 and will accelerate the country's goal to a target of at least 2GWp of solar energy by 2030 ..read more

In a nutshell, if you purchased a cable that is manufactured to international standards, and wired indoors according to proper guidelines, your cables are generally expected to last based on a design life of at least 20-30 years ..read more

A structured cabling system (SCS) is a set of cabling and connectivity products that integrate voice, data, and various other ELV systems on the premise (eg. safety alarms, security access, energy systems). It is a web that connects all the devices together through smaller standardized elements - providing a reliable and future-proof solution to a wide range of communication requirements ..read more
