The world welcomes home Solar Impulse

14th December 2016 - Testing, Company News

A task once thought impossible by even the most hopeful of Ecologists, the world’s first solar airplane, Solar Impulse, has landed in Abu Dhabi; completing a groundbreaking, zero-flight mission spanning an incredible 40,000km around the world. The journey, which began in March 2015, saw 2 ambitious and visionary pilots - supported by many a team of experts - take to the skies to demonstrate the capabilities of clean energy, capturing the hearts and minds of the entire world as they did so.…

Ice Cold and Still Cool: reliability in the most extreme temperatures

6th February 2015 - Testing, Rail - Infrastructure, Protection From Rats

pma-snow1As extreme weather conditions continue to sweep through Europe and across the UK - with temperatures skipping carelessly between glacial and unseasonably mild (although we did enjoy building snowmen in February with our sunglasses on!) - it's vital that railway systems operate safely and efficiently with minimal risk of damage or delay. PMA's cable protection systems are specifically designed to withstand extreme weather conditions and our products are renowned within the industry for their superior…

Case Study: Cold Impact Testing – PMA’s products continue to amaze

20th October 2014 - Testing, Rail - Infrastructure, Hazardous Areas, Case Studies

PCS Siemens storyA Finnish rail company - a customer of Siemens - have questioned the general use of polyamide corrugated cable protection systems due to breakages to conduits as a result of poor ageing characteristics and high impact energies at low temperatures. It is important to note that these experiences had nothing to do with any PMA products, but with conduits from another, unrelated, company. This loss of confidence in polyamide materials led them to begin searching for alternative cable protection…

System pull-out strength

1st December 2013 - Testing

pulloutAll together now, streettch! At PMA, we place a great deal of importance upon the performance of our conduit when placed under pressure. Around the world, thousands of miles of cables (which are vital to general functioning and safety) are protected by our systems, so we make sure our products pass and excel in every test – from load-bearing and flexibility whilst being exposed to temperature changes, to compression and expansion. In this test, our conduits and connectors are under the microscope:…

Thermal ageing test

1st December 2013 - Testing, Rail - Rolling Stock

Thermal-testing  Prolonged heat exposure weakens almost anything, but when it comes to PMA cable protection, our thermal ageing test gives us the reassurance that our conduit will continue to perform, exhibiting strength and resistance, despite having to perform in extremely hot conditions – such as the desert.   We do this by placing test conduits in a controlled-climate oven at a specified test temperature – we then turn up the heat to 160°C for 168 hours/7days. Once removed from this…

Peak load test

1st December 2013 - Testing

peakloadIt’s vital that PMA’s cable protection systems continue to hold their own when exposed to temperature changes, hazardous conditions and constant movement – but one of the most important tests for us is how our conduit behaves when put under pressure, literally, from all sides. Our peak load test is more than just a gentle squeeze – a defined pressure is slowly applied to the conduit by two steel plates positioned either side of the tubing. At PMA, compression strength tests…

Impact Test

1st December 2013 - Testing

impactAs portrayed in the famous PMA hammer test (see video below), we’re so confident of the resilience and strength of our range of nylon cable protection systems, we’re willing to risk our limbs (or a pinky at least) to prove their protective nature. Just as in the hammer test, we expose PMA products to an impact strength test which involves the conduit being placed on a steel plate and positioned under an impact head with a defined profile (a sharp, hard object, to you and me). This…

Don’t put yourself out – we will!

1st December 2013 - Testing

flameAnti-flammable qualities are of the utmost importance in hazardous environments such as factories, power stations or energy plants. In order to comply with the strict requirements of such environments, PMA has developed a self-extinguishing polyamide from which their systems are made, which enables it to diffuse any flame and continue to offer protection to internal cabling when exposed to fire for a good length of time. We have our own internal specifications set for when we expose PMA conduits…

Cold test

1st December 2013 - Testing, Rail - Rolling Stock

coldNot only do we twist, load, bend and flex our conduits to breaking point, we also manipulate conditions and pressures to see just how each of our products react to extremes of all kinds. Polyamide, or nylon, conduit is known to display resistance to many things – from seawater to rats(!), but one of the most important benefits of PMA’s products is their ability to retain strength and flexibility in a broad spectrum of temperatures and weathers. To test this, we have a special cold test…

The third reversed bending test

1st December 2013 - Testing

circleAt PMA, we are nothing if not thorough. Our lab technicians put an emphasis on exposing our cable protection systems to extreme pressures, temperatures, conditions and wear and tear to ensure they live up to, and exceed, expectations – and perform exactly as they should. It’s because of this testing that PMA products are installed into the vital components of wind turbines – because when your state-of-the-art system is 100m in the air and out at sea, you can’t afford for…
