New Cable Standards for Wind Turbines

Wind Turbines
There have been some changes to the wiring of wind turbines over the last year, as electrical systems on large wind turbines are now subject to a new standard. This standard is the UL 6141 which could see some drastic changes to cabling practices.

Both new and refurbished wind turbines that generate more than 500 kilowatts have to follow these standards. This new standard also proposes strict limits on the use of appliance-wiring material (AWM) within and between key generator subsystems.

These limits come from a requirement that all accessible wiring must either be enclosed in a raceway, or rated for tray cable usage. The new standards could affect different wind turbine subsystems, and here are a few example of how:

The Gearbox – There is no UL component standard specifically for gearboxes, therefore the UL 6141 will apply to the wiring for these components which relates to heaters and PT 100 temperature sensors as an example.

Generators – The existing UL component standard for generators permits AWM cables under limited circumstances. In order to use AWM in generator wiring, a ready-to-connect cable with connector must be set in place. This should also be fitted with a grounding cable within the generator itself. Since neither of these options is common with wind turbine generator manufacturers in today’s industry, UL listed cable products will likely be the safest design strategy now UL 6141 has arrived.

Tower – UL 6141 applies to towers as there is no existing UL for these. This clearly calls for listed products for cables that run vertically up the tower, including those for power, control signals, lighting and hoists.

While UL 6141 won’t necessarily outlaw AWM in wind turbine subsystems, a preference for listed cable products comes through loud and clear in the new standard. It remains to be seen whether electrical inspectors will accept AWM cable when it is known that the intent of the UL 6141 would be the use of listed cable products.

Design engineers working on new turbine projects may want to keep this preference for products in mind. Using listed products only will not only result in more durable wiring but will also ensure compliance when UL 6141 goes into effect.

The Importance of Road Haulage in the UK

Road Haulage
Road haulage in North West England and other parts of the UK is an essential enabler of economic growth, employment and wealth creation. The majority of everyday items we use; our necessities such as food, drink and clothing, depend on haulage services to deliver them to our nearest stores and outlets.

Road transport is highly competitive and it is a service-driven industry which responds to the fluctuating demands of customers. The industry develops as both regulations and road conditions change.

Road Haulage Associations represents the industry as clean, innovative, modern, and committed to safety, as well as an essential asset to the UK economy. The UK Government has provided a generous amount of funding for the haulage sector during the period 2015 – 2020. Funds of £500 million are set to support the development of diverse fuels and more efficient vehicles.

Additionally, the industry has a big interest in the condition of its roads and there are a number of other road factors that could benefit highly from further investment. Drivers of any vehicle use the roads to go to their place of work – factories, shops and office. The road network is where the haulage industry is at work. The conditions of the roads affect costs and the ability for staff to do their job efficiently.

Roads should remain well-built and maintained, with even surfaces to make driving safer but to also minimise road noise. The Road Haulage Association proposes the use of signalling technologies to improve traffic flow, as well as information technology to ensure road users have timely and reliable information.

Lastly, the latest trucks on sale meet Euro 6 emissions standards to help mitigate the impact HGVs have over air quality. The transport industry is becoming more advanced and vehicles are far more efficient with fuel and the pollution they produce, creating a cleaner industry than ever before.

Coastal Defence Projects in the UK

coastal defence
Project work for defence contractors in the UK is increasing, with more and more coastal defence work taking place to protect local communities. A great amount of work has commenced during the first half of 2015, with many more projects planned to go underway later on in the year.

Next week coastal defence work will start along Llanddulas tip in North Wales. This is to repair and reinforce the damaged defences over the frontage, which stretches over 810m. The work will involve removing the protection system, a geotextile membrane will then be installed and the rock armour revetment will be re-graded and enlarged.

Defence contractors in the UK complete projects to the highest standard and efficiently, but no project is the same with regards to its set time frame. The work taking place in Llanddulas is expected to take two months to complete, whereas other projects on the go are expected to be completed in the very early new year of 2016.

Market leaders in the supply and placement of graded rock armour for defence projects are providing defence contractors with the opportunity to protect the local communities. If you live close by to the coastline in your area, your household is at higher risk during torrential weather.

Dramatic weather changes can have a very negative impact on the local area, affecting the day to day running of the local area. Footpaths and cycle paths are likely to be closed in the aftermath due to health and safety, roads which stretch along the coastline would also be closed, but also flooding often takes place after a drastic coastal event.  

Fortunately, there is a new national database that holds details of coastal flooding in the UK, which has built up over the last 100 years. This new database called SurgeWatch is set to help prevent coastal flooding by allowing sea defence contractors in the UK to access this useful tool.
