Genuine LSF Gland Shrouds vs Non-Genuine LSF Shrouds
In recent years there has been a massive influx of imported products, such as cable gland shrouds, which claim to have equal characteristics to their traditional counterparts. Our video outlines the difference in quality between genuine LSF gland shrouds and ‘economy’ LSF shrouds. Transcription: “The following video clip demonstrates the differences in so called LSF […]
Earthing Requirements of Cable Glands Used on SWA Cables
When cable glands are used to terminate SWA (Steel Wire Armour) cables, the gland must be able to provide earth continuity from the termination of the armour through to the body of the equipment, either via the enclosure itself (if it is metallic), via a gland plate or through an external earth path with the […]
How engineering has changed on the London Underground in the past 150 years
2013 marked the 150th year since the London Underground became the first underground rail system. On that day, around 40,000 people were carried on the service that ran between Farringdon Street and Paddington. Since the early days of gas lit platforms, steam powered trains and class division and now with around 3.5 million daily users, […]
The Importance of Correctly Cleating Cables
The importance of correctly cleating cables in a trefoil formation within electrical installations is frequently underestimated, often due to a lack of understanding. Many people assume cleats are used purely to hold the power cables to the desired route, but for an installation of single core cabling system to be deemed safe, it is vital […]
Heat Shrink vs Cold Shrink: Knowing When Each One Is More Suitable
Cold Shrink and Heat Shrink tubing may appear similar from the outside, but their key characteristics are very different. Both types of tubing have different installation techniques, applications and physical properties. HeatShrink and ColdShrink tubing can be used for a variety of cabling applications including: terminating, splicing and providing environmental seals on LV and MV […]
Stainless Steel Cable Cleats and Galvanic Corrosion
How the issue of galvanic corrosion affects installation of stainless steel trefoil cleats onto galvanised steel support structures in various environments. The term galvanic corrosion refers to corrosion induced when there is electrical contact between two dissimilar metals in the presence of an electrolyte, i.e. water or corrosive vapour. The severity of the corrosion is […]
